Output over-voltage pro-tection

The output over-voltage protectionthreshold is set to (61 ± 1) VDC and it isnot adjustable. If the output voltage isgreater than this value, the rectifier stopsworking. In this case, turn off the AC inputpower, troubleshoot it and then restart it.

Output over-current pro-tection

To prevent the over-current protectionfrom being prior to the current limitingprotection, the response of the over-cur-rent protection should be slower than thecurrent limiting protection; in addition, theover-current protection threshold shouldbe greater than the maximum currentlimiting threshold. The over-current pro-tection threshold of the rectifier is (60 ±2) A.

Over-heat protection andtemperature control

Normally, the fan rotates at half speed orat full speed according to the temperatureof the heat sink.� If the temperature is less than 50°C,

the fan rotates at half speed.� If the temperature is greater than

50°C, the fan rotates at full speed.To protect the rectifier from damage, thenegative temperature coefficient thermis-tor of the equipment controls the highesttemperature when the fan is faulty or thefan rotates at full speed but the tempera-ture of the heat sink still rises. The detailsare as follows:� If the temperature is over the

threshold, the DC-DC circuitstops working.

� When the temperature is belowthe threshold, the DC-DC circuitstarts working.

For example, the system is configured with one -48 V battery packconsisting of 24 batteries (2 V/battery). The temperature com-pensation coefficient is set to 3 mV/℃. The battery temperatureis 30℃. The charging voltage decrease is calculated according tothe formula below.

⊿V=30℃-25℃×3 mV/℃×24=360 mV= 0.36 VIf the floating charge voltage is set to 53.5 V in floating chargemode, the system output voltage is: 53.5 V - 0.36 V = 53.14 V.

Value Range 0 mV/℃ to 8 mV/℃, 3 mV/℃ by default.



SettingRequirements

Set this parameter according to the battery charging features.

Cur.Temp.Co.


Cur.Temp.Co. is a hidden parameter. Its interface is shown inFigure 74.

FIGURE 74 CUR.TEMP.CO. INTERFACE

ParameterMeaning

This parameter indicates the charging current rate (C/℃) to bedecreased when the battery temperature (T) is higher than 25℃.When the battery temperature is higher than 25℃, the system low-ers Cur. Limited through this parameter according to the batterytemperature, and thus to lower the maximum charging currentand avoid overcharge. So setting Cur.Temp.Co. can further lowerthe maximum charging current.

The formula is as follows:

I= Battery capacity ×[Cur. Limited - (T-25℃) × Cur.Temp.Co.]For example, the system is configured with a 300 Ah battery pack.Cur. Limited is set to 0.15C and Cur.Temp.Co. is set to 0.001C/℃.If the battery temperature is 30 ℃, the maximum charge currentis calculated as follows:

I=300 Ah× 0.15C- 30℃-25℃ ×0.001C/℃ =300 Ah× 0.15C-0.005C=43.5 A

Value Range 0 C/℃ to 0.010 C/℃, 0 C/℃ by default.

SettingRequirements

Set this parameter according to the battery charging features.

Note:

The decrease of Cur. Limited after temperature compensation can-not be greater than a half of the original Cur. Limited; otherwiseCur.Temp.Co. is invalid.

Temp.Volt.Max. and Temp.Volt.Min.


Temp.Volt.Max. and Temp.Volt.Min. are hidden parameters.Their interfaces are shown in Figure 75 and Figure 76 respectively.



FIGURE 75 TEMP.VOLT.MAX. INTERFACE

FIGURE 76 TEMP.VOLT.MIN. INTERFACE

ParameterMeaning

It limits battery charge temperature compensation:

� The system compensates temperature only when Float Vol. orEqual Vol. lies between Temp.Volt.Max. and Temp.Volt.Min.

� If the compensated result is greater than Temp.Volt.Max.,the system takes Temp.Volt.Max. as the result. If the com-pensated result is less than Temp.Volt.Min., the system takesTemp.Volt.Min. as the result.

� The system does not compensate temperature if Float Vol.or Equal Vol. does not lie between Temp.Volt.Max. andTemp.Volt.Min.

Value Range � Temp.Volt.Max.: 50.0 V to 58.0 V, 57.0 V by default.

� Temp.Volt.Min.: 50.0 V to 58.0 V, 50.0 V by default.

� Constraints: Temp.Volt.Max. ≥ Temp.Volt.Min.

SettingRequirements

Battery Temperature Threshold

Bat.Temp.Max.


Bat.Temp.Max. is a hidden parameter. Its interface is shown inFigure 77.

FIGURE 77 BAT.TEMP.MAX. INTERFACE

ParameterMeaning

FIGURE 79 BAT.DISCH.VALVE INTERFACE

ParameterMeaning

Threshold of battery discharge. When the battery dischargecurrent reaches this value, the system gives the “Bat.Discharge”alarm.

Value Range –4 A to –50 A, –10 A by default (discharge current is negative,while charge current is positive).

SettingRequirements

Set this parameter according the battery discharging features.

Volt.Dev.


Volt.Dev. is a hidden parameter. Its interface is shown in Figure80.



FIGURE 80 VOLT.DEV. INTERFACE

ParameterMeaning

Voltage deviation in the transition phase. When mains recoversfrom failure, the rectifiers do not power the loads. The specifiedoutput is equal to the minimum battery voltage plus Volt.Dev..Therefore, the batteries can power the loads instead, and thus toavoid startup failure because of the generator startup problem.This process lasts about 30 seconds.

Value Range –2 to –0.5, –0.5 by default.

SettingRequirements

Set this parameter according the battery discharging features.

Work ModeSafe Mode

Safe mode is a redundancy work mode based on reliability.

In safe mode, the system calculates the number (N) of requiredrectifiers based on total load current and maximum battery chargecurrent and performs N+1 backup. N should be an integer. Theformula is shown as follows:

For example, total load current is 20 A, battery capacity is 300 Ah,and rated SMR output current is 50 A. If Cur. Limited is set to 0.15C, the number (N) of required rectifiers is equal to (20+300×0.15)/ (50×0.7)+1≈3.

Note:

Safe mode is limited by Smr Limit Num.. If the calculated valueis less than the preset value of Smr Limit Num., Smr Limit Num.is taken as the number of required rectifiers.

In safe mode, the system control turning-on of rectifiers based onthe following rules:

� When the system runs normally, if the number of normallyworking rectifiers is less than the number of required recti-fiers, the system automatically turns on rectifiers that are notworking until both numbers are the same.

� If the number of normally working rectifiers is greater than orequal to the number of required rectifiers, the system does



not control rectifiers. That is, in safe mode the system canonly turn on rectifiers automatically.

Save Mode

Save Mode can guarantee that the rectifier efficiency is always thepeak value to save more power.

In the save mode, four work modes are available: Auto Save Mode,Temp NonSave Mode, Perm NonSave Mode, and Manual Detect.

Auto Save Mode Depending on whether the system satisfies the save conditions,auto save falls into Auto Save Mode and Auto NonSave Mode.

� When save conditions are not satisfied, the system enters AutoNonSave Mode automatically. All the rectifiers are opened.

� When save conditions are satisfied, the system enters AutoSave Mode. Smr Limit Num. and Rotate Period are involvedin auto save.

� In auto save mode, the number of normally working rec-tifiers controlled by the system equals the number of re-quired rectifiers (an integer). The system adjusts the num-ber of required rectifiers depending on real-time load cur-rent and charge current so that rectifiers can work withhigh efficiency. Meanwhile, the number of required recti-fiers must be greater than or equal to Smr Limit Num..

� In auto save mode, once the switching period is over,the system opens the rectifier that is shut down for thelongest time and shuts down the one that has worked forthe longest time. If the rectifier to be opened is faulty, thesystem does not shut down another rectifier to make surethat the number of normally running rectifiers equals thenumber of required rectifiers.

Temp NonSaveMode

In Temp NonSave Mode, the system performs the following oper-ations:

1. Opening all rectifiers first.2. After a period of NonSave Delay (24 hours by default), switch-

ing to auto save mode.

NonSave Delay can be configured in Setup Para > Batt Para> NonSave Delay.

Perm NonSaveMode

In Perm NonSave Mode, the system opens all the rectifiers andstays in this mode unless it is manually set to another work mode.

Manual Detect In this mode, maintenance personnel can check running of thesystem save program as well as battery and rectifier status.

After having entered the Manual Detect mode, the system per-forms the following operations:

1. Opening all the rectifiers first and triggering periodical batterydetect at the same time. Battery detect duration depends onthe setting of Bat.Det.Time, 2 minutes by default.

2. After battery detect, if save conditions are satisfied, switchingrectifiers; otherwise, after a certain delay, the system entersthe auto save mode.



The process of switching rectifiers is as follows:

i. Opening the required rectifiers starting from the smallestnumber of slot in which a rectifier is in position.

ii. Turning on and then turning off all the in-position and nor-mally running rectifiers based on the slot sequence.

3. After a certain delay, switching to the auto save mode.

Free Mode

In the free mode, the monitoring software can freely control on/offof the rectifier without limit. In this mode, when the load currentis greater than the sum of rated current of all opened rectifiers,the rectifiers will limit current and lower voltage. As a result, thebatteries will discharge.

Caution:

Free mode is suitable for system debugging. Only professionalmaintenance personnel can use this mode.

Selecting Work Mode

Context The system supports three work modes: Safe Mode, Save Mode,and Free Mode. The default is Safe Mode.

Take Save Mode as the example. The operation flow is shown inFigure 81.

Emergency HandlingEmergency Handling Principle

The basic principle of emergency handling is to keep the DC powersupply for the communication equipment.

In power system, the following faults will affect communicationquality or cause communication interruption:

� Permanent damage of the circuit in the AC distribution unit.

� Short circuit of the DC load or the DC distribution unit.

� All the rectifiers are faulty.

� The disorder of the monitoring unit leads to the system shut-down.

� DC over-voltage leads to the shutdown or lock of the rectifiers.In this case, turn off the AC power, troubleshoot the fault andthen restart the rectifiers.



Emergency Handling of ACDistribution Unit

TABLE 36 EMERGENCY HANDLING OF AC DISTRIBUTION UNIT

Symptom Solution

The fault of the AC distributionunit leads to the interruption ofthe AC input power.

Directly introduce AC power intothe rectifiers.

Emergency Handling of DCDistribution Unit

TABLE 37 EMERGENCY HANDLING OF DC DISTRIBUTION UNIT

Symptom Solution

The system has no output on aload branch due to short circuit.

Turn OFF the corresponding loadair switch.

The short circuit of the DCdistribution unit affects thecommunication.

� [Solution 1] Turn OFF the ACinput, disconnect the batteriesfrom the system, and use thebatteries to power the loadsdirectly.

� [Solution 2] .

Disconnect the rectifiers fromthe system. Connect the ACinput cables and DC outputcables to their respective I/Oterminals.

Turn ON the AC input to powerthe rectifiers and the rectifierswill power the loads directly.

Emergency Handling of MonitoringUnit

Note:

When the system works without the monitoring unit, the systemdoes not have the function of battery management.


Chapter 6 Emergency Handling and Maintenance

TABLE 38 EMERGENCY HANDLING OF MONITORING UNIT

Symptom Solution

The fault of the monitoring unitaffects the DC output of the powerequipment.

Uninstall the monitoring unit andtroubleshoot it.

Emergency Handling of Rectifier

TABLE 39 EMERGENCY HANDLING OF RECTIFIER

Symptom Solution

Some rectifiers are faulty. If the remaining normal rectifiersare able to power the loads, justpull out the faulty rectifiers.

When the load current is lowerthan the capacity of one rectifier,the output over-voltage ofsome rectifier will lead to theover-voltage of the power systemand all the rectifiers will be inover-voltage protection status.This fault cannot automaticallyrecover.

1. After confirming that thebatteries are able to supplypower normally, turn OFF theair-switches of all rectifiers.

2. Turn ON the rectifierair-switches one by one.The corresponding rectifier isfaulty if the DC over-voltagealarm occurs again when anair-switch is turned ON. Inthis case replace the faultyrectifier.

3. Turn OFF the AC input power.4. Turn ON the air-switches of all

the rectifiers.5. Turn ON the AC input power

to restart the rectifiers. Thenthe system will work normally.

MaintenanceRoutine Maintenance

Table 40 describes routine maintenance items.



TABLE 40 ROUTINE MAINTENANCE ITEMS

MaintenanceItem Description

Surge arrester

Each day or after lightning storm, check whetherthe lightning arresters are damaged. If yes, repairor replace them in time.

[Acceptance Criteria]

� Varistors of class C lightning arresters arenormal. Window display of the arresters isGREEN or COLORLESS.

� If three indicators of DC surge arrester are onat the same time, the internal fuse is normal.

[Check Methods]

1. Observe the window of the class C lightningarrester. If the window turns red, the arrestersare faulty. Replace the arresters.

2. Observe the three indicators of DC surgearrester to see if they are all glowing. Ifone of them is off, it means the fuse of thecorresponding DC arrester loop is OFF andthe fuse needs to be replaced. Even if one ortwo indicators are OFF, DC surge arrester stillhas the function of DC lightning protection.However, if all of the three indicators are OFF,DC surge arrester will cease to be in effect andfuses have to be replaced.

Communicationfunctions


Each unit of the system communicates normallywith the monitoring unit. There is no such alarm inhistory alarm records that some single unit has lostcommunication for several times.

System Operating PrinciplesFigure 129 shows the block diagram of the ZXDU68 T301 systemoperating principle.

FIGURE 129 OPERATING PRINCIPLES OF THE ZXDU68 T301

� The AC distribution unit inputs and distributes the AC powersupply and performs the related protection function.

� The rectifiers perform AC/DC conversion.

� The DC distribution unit outputs DC power, connects battery tothe system and performs load protection.

� The monitoring unit collects information, performs signal con-version and alarm functions.



Operating Principles of ACDistribution UnitThe operating principles of the AC distribution unit are shown inFigure 130.

FIGURE 130 OPERATING PRINCIPLES OF AC DISTRIBUTION UNIT

� The two AC input branches supply AC power to the rectifiersthrough the switching unit (if there is only one AC input branch,the switching unit is not needed).

� The AC transducer transmits the required AC input parametersto the monitoring unit.

� The lightning protection (or AC input lightning protection) is alightning proof unit.

� Each AC input phase provides an appropriate AC auxiliary out-put, to supply an auxiliary AC power to the loads.

Operating Principles of DCDistribution UnitFigure 131 shows the block diagram of DC power distribution unit.


Appendix A Operating Principles and Functions

FIGURE 131 DC DISTRIBUTION UNIT OPERATING PRINCIPLES

� The rectifiers supply power in parallel to the DC distributionunit through the copper busbar.

� Load and battery loop are configured with shunt; the shuntsserve to detect total load current and battery current. In addi-tion, on each load branch and each battery branch, a fuse or airswitch is configured for over-current protection and short-cir-cuit protection.

� The DC distribution unit has the LLVD function. If the batterydischarging time is excessively long and no emergency proce-dures has been taken, the system will disconnect the less-im-portant loads if the battery voltage falls to a limit; the systemwill disconnect all the loads if the battery voltage falls to a lowerlimit to prevent batteries from damage caused by over-dis-charge.

� The DC lightning arrester provides DC lightning protectionfunction.

Operating Principles ofRectifierThe operating principles of the ZXD2400 (V4.3) rectifier are shownin Figure 132.



FIGURE 132 RECTIFIER OPERATING PRINCIPLES

The principles are described as follows:

� The ZXD2400 (V4.3) rectifier operates from 110 V AC/120 VAC/127 V AC or 220 V AC source.

� The input EMI, soft start, surge/lightning protection rectifi-cation and input surge current limiting circuits feature smallstartup surge current and good EMC. After the input AC is rec-tified, it will directly enter the front PFC circuit.

� The main circuit of the front PFC is the BOOST circuit. The PFCcircuit uses the averaged current mode/peak current mode tocontrol the input power factor (the input power factor becomesapproximately equal to 1). The harmonic current is less than5%. The PFC circuit also adjusts the input voltage to a stable410 V DC voltage to be provided for the back DC-DC conversioncircuit.

� The back DC-DC conversion circuit adopts the phase-shift full-bridge power inversion technology. The circuit converts 410 VDC to 48 V DC.

� The PFC circuit and the DC-DC conversion circuit have reliablecontrol and protection function.

� The control interface transmits the working status and alarmdata of the rectifier to the monitoring system. The monitoringsystem implements the three tele-functions through the con-trol interface. For example, adjusting the output voltage of therectifier and turn it on/off through the control interface.

� Status display is composed of several indicators that indicatethe working status of the rectifier.

� The auxiliary power supply provides power for the internal con-trol circuit and the fan of the rectifier.


Appendix A Operating Principles and Functions

Functions of the MonitoringUnit

Short Description The monitoring unit detects the operation status of system andautomatically controls the operation of the whole system. Inaddition, it transmits the data to the remote monitor PC or remotemonitor center through the communication interface, realizingunattended maintenance.

The functions of the monitoring unit are described as follows:

� Data collection and processing

Monitored Object Data Collection and Processing

AC distribution unit AC voltage, AC current, AC input air switchstatus and class C surge arrester status

DC distribution unit

DC output voltage, battery voltage, batterycurrent, total load current, status of load out-put breaker, status of DC contactors and DCarrester status

Rectifier modulePower-on/off control of rectifier module, re-charge status control and in-position and faultdetection

� Man-machine interactive interface

The LCD and keys enable the user to set the system runningparameters and query the related information.

� Communication

The monitoring unit provides multiple communication inter-faces, such as RS232/RS485/modem. Centralized monitoringcan be implemented through modem or in other ways.

� Alarm reporting management and protection

The monitoring unit processes real-time data, as set by users.If a serious fault occurs, the unit generates an alarm and re-ports it to the background PC automatically; in addition, theunit records and stores fault information. The user can alsohave access to alarms through the monitoring unit directly.The details are shown below:

Item Description

Alarm settingThe user can set the upper and lower limitsof the system parameters accordingly.

Alarm management The system has reliable and real-time alarmmanagement function.

In case of any alarm, the monitoring unit gen-erates audible and visual signal to inform themaintenance personnel and reports the alarminformation to a background PC through itscommunication interface.

Alarm mode



Item Description

Press any key to mute the alarm sound; thenthe ALM indicator keeps glowing until thefault is eliminated.

� Battery management function

� Battery charging management

The system has three battery charging modes:

S/N Description

1The system periodically recharges the batteries accord-ing to the period set by the user.

2

When the mains supply recovers after failure and thebattery discharges its capacity to a certain degree, whichcan be set by the user, the system automatically re-charges the batteries.

3

When the batteries are of full capacity, the system keepscharging them; the system provides constant floatingcharging voltage and low floating charge current to thebatteries.

� Battery protection function

When the mains supply is cut off, the battery supplies thepower. The corresponding alarm is generated when thevoltage of the battery falls to a certain degree (settable).

The system has LLVD function. When the battery voltagefalls to a limit, the system shuts down the less-importantloads; after that, when the battery voltage falls to a lowerlimit, the system shuts down all the loads. LLVD functionis to ensure that important loads work longer and protectbatteries from over-discharge.

In addition, the maximum charging current can be set toprotect batteries. The maximum charging current is equalto the limited battery current multiplied by the battery ca-pacity. Therefore, to set limited battery current is to limitmaximum charging current.

� Control

The monitoring unit of the system and the monitoring softwareon the background PC enable the user:

� To control the rectifier power-on, power-off, equalizedcharging and float charging.

� To adjust the rectifier output voltage within the range from-42 V to -58 V.

Table of ContentsAC Distribution Part ......................................................... 169DC Distribution Part ......................................................... 170Rectifier Part................................................................... 170Battery Part .................................................................... 171Communication Part......................................................... 172

AC Distribution PartThe AC distribution part is described in Table 47.

TABLE 47 AC DISTRIBUTION PART

Term Description

Mains Primary AC input source for the power supplyequipment.

GeneratorSecondary AC input source for the power supplyequipment. Diesel generator or gasoline gener-ator are the most commonly used.

3-phase 5-wiresystem

The connection mode of AC power supply, includ-ing phase wires of 3 AC phases (U, V and W),neutral wire (N) and ground wire (PE).

Single-phase 3-wiresystem

The connection mode of AC power supply whenthe user has only signal phase AC power, includ-ing phase wire (live wire, L), neutral wire (N) andground wire (PE).

Air switch

Also called automatic air switch or circuit breaker.It is a kind of circuit protection facility, capa-ble of automatic disconnection upon overload orshort-circuit. The air switches used in the com-bined power system involve AC power input end,lightning arrester air switch, AC standby output,rectifier AC input and load output.

AC contactor A kind of over/under-voltage protection device ofthe AC circuit, used for the AC input power.



Term Description

AC transducer Used for detecting the AC input voltage and cur-rent.

AC lightningarrester

Generally used in AC level C lightning protec-tion. Its purpose is to discharge the high cur-rent caused by lightning or surge current inputby power supply network. The lightning arrest-ers used in ZTE DC power system are of OBO andPHOENIX brands. The OBO lightning arrester hasa small mechanical window, which is normallygreen when the arrester is normal and turns redif it is damaged. The window of the PHOENIXlightning arrester has no color in normal case andred in damaged case. It is required to regularlycheck the lightning arrester and immediately re-place it if its window turns red.

DC Distribution PartThe DC distribution part is described in Table 48.

TABLE 48 DC DISTRIBUTION PART

Term Description

FuseFuse protector. When over-load or short-circuitoccurs on the line, the fuse will break, and thusdisconnecting the circuit.

DC contactorUsed for under-voltage protection of the battery,emergency lighting control and load low voltagedisconnection function.

First Load LowVoltage Disconnect(LLVD1)

When the AC power input fails, the batterypowers the load. The discharging of the batteryleads to a gradual decrease of the output volt-age. When the voltage falls to the threshold ofthe LLVD1, the system will automatically shutdown less important load. Due to reduced load,the battery can power the important load for alonger time.

Second Load lowVoltge Disconnect(LLVD2)

When the voltage falls to the threshold of theLLVD2, the system will automatically cut off theentire load. After all the load is cut off, the cease-less discharging of the battery is terminated, andthus preventing the battery from damage due toexcessive discharging.

Load Equipment powered by the combined power sup-ply.

Rectifier PartThe rectifier part is described in Table 49.


Appendix E Explanations of Common Terms

TABLE 49 RECTIFIER PART

Rectifier

A rectifier converts AC power into DC power. Inthe DC power system, multiple rectifiers work inparallel connection mode, with the total outputcapacity equal to the sum of the output currentof every rectifier.

Current limiting

An over-load protection function. When the rec-tifier current exceeds the pre-set value, the out-put current will be limited. When input voltage ofthe rectifier is too low, the current limiting pro-tection will take effect as well.

Battery PartThe battery part is described in Table 50.

TABLE 50 BATTERY PART

Term Description

Battery

The battery used in the DC power supply systemis usually sealed lead-acid maintenance-free bat-tery. This kind of battery is almost free of mois-ture loss in the recharging/discharging, so watersupplement is unnecessary and erosive gas canbe avoided, and thus requiring no maintenance.The standard battery voltage can be 2 V, 4 V, 6V, or 12 V (mostly used in DC power system).24 pieces of batteries are connected in series toform a 48 V battery group.

Floating charge

Recharging mode of the battery. When the bat-tery is full, the charger will not stop recharging,instead, it still provides constant floating chargevoltage and small floating charge current for thebattery. Once the charger stops recharging, thebattery will naturally discharge power. Thus, thefloat charging mode is used to balance this natu-ral discharging. Usually, the float charging volt-age is 53.5 V.

Equalized charge

Recharging the battery in the mode of specifiedcurrent and specified time, featuring a short re-charging time. This recharging mode is oftenused when the professional maintenance person-nel maintain the battery, facilitating the activa-tion of the chemical features of the battery. Usu-ally, the equalized charge voltage is 56.4 V.

Battery capacity

Usually represented with AH. It is an importantbasis for recharging/discharging management ofthe battery. Thus, it is required to properly setthe battery capacity of the system upon commis-sioning.



Term Description

Battery temperaturecompensationcoefficient

The leakage current of the battery is sensitive totemperature. To suppress leakage current, tem-perature compensation is applied to the batteryvoltage. Usually, the compensation level is 25°C.When the battery temperature increases by 1°C,the voltage of each battery decreases by 3 mV;when the battery temperature decreases by 1°C,the voltage of each battery increases by 3 mV.

Battery temperaturesensor

Used for detecting the battery group tempera-ture.

Discharge Process during which the battery supplies powerto the load.

Over dischargeThe case in which the battery voltage is equal toor even lower than the nominal lower limit. Theexcessive discharging heavily harms the battery.

Communication PartThe communication part is described in Table 51.

TABLE 51 COMMUNICATION PART

Term Description

Dry contactPassive contact, used for signal transfer anddivided into normally-close contact and nor-mally-open contact.

RS232

A kind of serial communication physical inter-face standard, commonly used for short-distancetransmission. It supports 3-wire transmission.Signals are divided into transmitting, receivingand signal ground.

RS485

Differential mode serial asynchronous transmis-sion data interface. It can implement multi-sta-tion interconnection and remote transmission.Usually, there are two data wires, supportingover 1000-m transmission distance.
