CautionIndicates a potentially hazardous situation, which if not avoided, could

result in minor or moderate injury. It may also be used to alert against

unsafe practices.

Electric shockThere is a risk of electric shock.

ElectrostaticThe device may be sensitive to static electricity.

Read the safety instructions before any operation of the equipment. The safety precautionsmentioned in this manual only serve as a supplement to the local safety codes.

Only trained professionals are allowed to install, operate and maintain the equipment. ZTEbears no liability to the consequences incurred by violation of the general safety operationrequirements, or violation of the safety standards for designing, manufacturing and usingthe equipment.

Take the following precautions when installing and operating the equipment.

High VoltageDirect contact or indirect contact with high voltage and mains through damp object willendanger the operator’s life.

l Observe the local safety codes during the equipment installation. The installationpersonnel must be qualified for high voltage and AC power operations.

l Never wear any conductive object, such as watch, hand chain, bracelet or ring duringthe operation on the equipment.

l Prevent any moisture from entering the equipment during operations.

No Object With Harmful EffectsProtect the equipment against ingress of objects with harmful effects, such as conductiveobject and water. Otherwise, short circuit may occur and damage the equipment!

I

High Leakage Current

Earth connection is essential before connecting supply.

DC Short Circuit

Avoid short circuit during operation. ZXDU58 W121 system is a power supply product ofconstant DC voltage.

Connecting or Disconnecting Power Cable

Power cable operation with power ON will cause fatal danger to operation personnel anddamage to the equipment.

l Turn OFF all the breakers and switches before connecting or disconnecting a powercable.

l Before connecting a cable, make sure that the cable and its label are in accordancewith the requirement.

Tools Safety

When operating high-voltage equipment, tools safety must be considered. Insulate thetools to prevent short circuit.

Electrostatic Damage

Electrostatic discharges generated by human body may damage components. Use wriststraps when handling the equipment. Insulate the uncovered metals to prevent shortcircuit.

Operation on Battery

l Before performing any operation on battery, read the safety precautions in the batterymanual.

l Connect the battery cables according to the instructions. Avoid short circuit andelectrolyte leakage.

Work Mode.................................................................................................................4-1Automatic LLVD Control .............................................................................................4-3

4.1 Work Mode

4.1.1 Types of Work ModeThe ZXDU58W121 system supports three work modes, SaveMode, Safe Mode and FreeMode. The default word mode is Save Mode.

l Save Mode

In Save Mode, five work modes are available: Auto Save Mode, Auto NonSaveMode, Temp NonSave Mode, Perm NonSave Mode, and Manual Detect.

l Safe Model Free Mode

Note:

In any workmode, current limit occurs to the rectifiers and the output voltage of the rectifiersfalls if the load current is larger than the sum of the rated current of all working rectifiers.As a result, the batteries will be discharged.

4.1.2 Save ModeSaveMode is a high-efficiency mode. It can guarantee that the rectifier efficiency is alwaysat the peak to save more power.

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

Auto Save Mode

In Auto Save Mode, the monitoring unit enables the system to switch to Auto Save Modeor Auto NonSave Mode according to the system configuration and real-time operationdata.

4-1



l Auto Save Mode

à The parameters related to Auto Save Mode are Smr Limit Num. (2, by default)and Rotate Period (7 days, by default).

à In Auto Save Mode, the system makes the number of normally working rectifiersequal to that of the required rectifiers. The system adjusts according to thereal-time load current and battery charging current so that the rectifiers can workwith their highest efficiency. In addition, the number of the required rectifiersshould be ≥ Smr Limit Num..

à InAuto SaveMode, the system rotates the rectifiers according toRotate Period.

The process for the system to rotate rectifiers is: The monitoring unitautomatically turns on/off rectifiers; the monitoring unit turns on the rectifierthat is shut down for the longest time and turns off the one that has workedfor the longest time. In the process, the monitoring unit guarantee three-phasebalance; in addition, the number of normally working rectifiers is equal to that ofthe required rectifiers.

l Auto NonSave Mode

When failing to satisfy the saving conditions, the system enters Auto NonSave Modeand turns on all the rectifiers.

Temp NonSave Mode

In Temp NonSave Mode, the system:

1. Turns on all the rectifiers first;2. Switches to Auto Save Mode after a period of NonSave Delay.

The NonSave Delay can be set and its default is 24 hours.

Perm NonSave Mode

In Perm NonSave Mode, the system turns on all the rectifiers and stays in this modeunless it is manually set to another work mode.

4.1.3 Safe ModeSafe Mode is a redundancy work mode based on reliability.

In Safe Mode, the system calculates the number (N) of the required rectifiers based onthe total load current and the maximum battery charging current, and performs the “N+1”backup. The formula is as follows. The number of required rectifiers should be an integerthat is equal to or larger than the result. For example, the number of required rectifiersshould be 4 if the result is 3.6.

4-2


Chapter 4 System Working

For example, the total load current is 10 A, the battery capacity is 300 Ah, and the ratedoutput current of the rectifier is 30 A. If Cur. Limited is set to 0.15 C, the number (N) ofthe required rectifiers in Safe Mode is: (10+300×0.15) / (30×0.7) + 1 ≈ 4.

Note:l The rated output current of the ZXD800 rectifier is 15 A.l The rated output current of the ZXD1500 rectifier is 30 A.l The rated output current of the ZXD030 S480 rectifier is 30 A.l The rated output current of the ZXD2400 rectifier is 50 A.

In Safe Mode, the number of required rectifiers is limited by Smr Limit Num.. If the resultof the above formula is less than Smr Limit Num., the number of required rectifiers shouldbe equal to Smr Limit Num. (2, by default).

In Safe Mode, the system turns on the rectifiers by the following rules.

l When the system runs normally, if the number of normally working rectifiers is less thanthe number of the required rectifiers, the system automatically turns on the rectifiersthat are not working until both of the numbers are the same.

l If the number of normally working rectifiers is greater than or equal to the number of therequired rectifiers, the system does not turn off the working rectifiers, which meanswhen in Safe Mode, the system can only turn on rather than turn off the rectifiersautomatically.

4.1.4 Free ModeIn Free Mode, the monitoring unit does not control on/off of the rectifier. In this mode,maintenance personnel can turn on or off rectifiers in the monitoring unit, withoutrestrictions of Smr Limit Num.

Caution!

Free mode is for system debugging. Only professional maintenance personnel can usethis mode.

4.2 Automatic LLVD ControlIntroduction to LLVD Control

The ZXDU58 W121 system has Load Low Voltage Disconnect (LLVD) function.

l LLVD1:

4-3



When the battery voltage falls to 1-Shut Vol., the system disconnects the secondaryloads (LLVD1 loads) to ensure that the important loads (LLVD2 loads) can work longer.At the same time, the monitoring unit gives the 1st Shut-Down alarm.

l LLVD2:

When the battery voltage falls to 2-Shut Vol., the system disconnects the importantloads (LLVD2 loads) to protect the batteries from over-discharge. At the same time,the monitoring unit gives the 2nd Shut-Down alarm.

Note:

The ZXDU58 W121 system can immediately power the loads with mains recovery afterfailure.

Related Parameters

Table 4-1 lists the default and range of the two related parameters, 1-Shut Vol. and 2-ShutVol..

In the monitoring unit, users can access Ctrl > 1. Setup Para > 2. Batt Para > 1-ShutVol. > 2-Shut Vol. to modify the value of the two parameters.
