WHAT IS THE PRODUCTINTERFACE?

The PowerLogic Product Interface for Life-gard Model 85A TemperatureControllers brings remote transformer temperature monitoring to the PowerLogicsystem. Any Square D PowerCast or conventional dry type transformer, equippedwith a Life-gard Model 85A Temperature Controller, can be monitored fortemperature and status. Table 1-1 lists the available data.

The Product Interface connects to the Model 85A Temperature Controller usingstandard RS-422 communications. The Product Interface can be located up to 4,000feet from the Model 85A.

The Product Interface provides standard RS-485 communications for connectionto a PowerLogic communications link. Multiple Product Interfaces and otherPowerLogic devices can be daisy-chained to a remote personal computer, asillustrated by Figure 1-1, or to a PowerLogic Network Interface Module (PNIM)for connection to a high speed network, as illustrated in Figure 1-2.

Chapter 3 Bulletin No. 3050IM9102Installation January 15, 1992

As in all other PowerLogic devices, the Product Interface uses an industry standardRS-485 (RS-422 compatible) electrical interface for data communications. Mul-tiple Product Interfaces, Circuit Monitors, and other PowerLogic devices can bedaisy-chained together on a single PowerLogic communications link. Figure3-3 shows multiple device types on a communications link.

All PowerLogic devices have RS-485 communications terminals for connection toa PowerLogic communications link. The Product Interface uses a removable, five-position terminal plug labeled “RS485 DATA COMMS” for this purpose. (SeeFigure 3-4).

As in all other PowerLogic devices, the Product Interface requires a communica-tion cable containing two shielded twisted pairs (Belden 8723 or equivalent).Communication cables are daisy-chained from the Product Interface’s RS-485communications terminals to the matching RS-485 communications terminals ofthe next device. That is, SHLD is wired to SHLD, OUT- to OUT-, OUT+ to OUT+,IN- to IN-, and IN+ to IN+.

If the Product Interface is the last device on the communications link, it must beterminated using a Multipoint Communications Terminator (MCT-485). SeeTerminating the Communications Link below for termination instructions. If theProduct Interface is the first device on the link, it must be connected to acommunications port using a Multipoint Communications Adapter (MCA-485).See Biasing the Communications Link below for biasing instructions.

If the Product Interface is between the first and the last device on the PowerLogiccommunications link, complete the following steps:

1. Strip back the cable sheath 2 inches on both ends of the communicationscable. Then strip back the insulation for each conductor 1/4 inch.

2. Inspect the stripped ends for stray wires to minimize the possibility ofshorts across terminals.

3. Connect one wire to the IN+ terminal on the Product Interface’s RS-4855-position terminal block. Connect the other end of the same wire to theIN+ terminal of the next device.

4. Repeat step 3, connecting the IN- terminal on the Product Interface to theIN- terminal on the next device, the OUT+ terminal on the ProductInterface to the OUT+ terminal on the next device, and so on.

For example, to wire a Product Interface to a Circuit Monitor, connect the SHLDterminal on the Product Interface to the SHLD terminal on the Circuit Monitor,connect the OUT- terminal on the Product Interface to the OUT- terminal on theCircuit Monitor, connect the OUT+ terminal on the Product Interface to the OUT+terminal on the Circuit Monitor, and so on.

To ensure reliable communications, the PowerLogic communications link must bebiased. This is done using a biasing device called a Multipoint CommunicationsAdapter (MCA-485). The adapter is placed between the first device on the link andthe communications port of the PNIM or SY/LINK card. Figure 3-6 illustrates theplacement of the adapter when the first device on the link is a Product Interface. Ifthe first device on the link is not a Product Interface, refer to the first device’sinstruction bulletin for biasing instructions.

To connect the Product Interface as the first device on the PowerLogic communi-cations link, you will need the following items:

• One PowerLogic Multipoint Communications Adapter (3090 MCA-485).(This is not included with the Product Interface and must be purchasedseparately).

• One PowerLogic cable 3090 CAB-107. (This is not included with theProduct Interface and must be purchased separately).

• A five position terminal block—1 provided with each Product Interface.

• Belden 8723 or equivalent cable. (Not included).

Figure 3-6 illustrates the wiring connections. Refer to this figure when completingthe steps listed below.

Biasing the CommunicationsLink

To connect the Product Interface as the first device on the PowerLogic communi-cations link, complete the following steps:

1. Install the terminal block in a convenient location.

The CAB-107 is a ten foot cable. If the terminal block must be locatedfarther than ten feet from the PNIM or PC, a custom cable must be built.To build a custom cable, use Belden 8723 cable and a male DB9 connector.Appendix C shows the required pinout for the CAB-107 cable.

NOTE: When connecting to a PNIM, connect the Product Interface to thetop RS-422 port, labeled port 0. This port must be configured for PowerLogicmode.

3. Mark the flying leads on the CAB-107 as indicated in the table below. Forexample, mark the white wire, labeled 20, as “IN+”; mark the green wire,labeled 21, as “IN-”; and so on.

4. Attach the Male DB-9 connector on the CAB-107 to the MultipointCommunications Adapter.

5. Connect the CAB-107 spade connectors to the terminal block.

6. Cut a length of Belden 8723 (or equivalent) cable that is long enough toreach from the terminal block to the Product Interface. Strip the cablesheath from both ends and expose 1/4" of each conductor.

7. Connect one end of the Belden 8723 (or equivalent) cable to the terminalblock.

8. Connect the other end of the Belden 8723 (or equivalent) cable to theremovable 5-position terminal plug, labeled RS-485 Data Comms, on theProduct Interface. Be sure to connect the terminal accepting the IN- wireon the CAB-107 to the IN- terminal on the Product Interface, the terminalaccepting the IN+ wire on the CAB-107 to the IN+ terminal on the ProductInterface, and so on.

An alternative to using a terminal block and a CAB-107 is to build acustom cable using Belden 8723 cable (or equivalent) and a maleDB-9 connector. When building the cable, follow the CAB-107pinout shown in Appendix C.

NOTE



To ensure reliable communications, the last device on a PowerLogic communica-tions link must be terminated. Figure 3-7 illustrates terminator placement when thelast device on the link is a Product Interface for Model 85A Temperature Control-lers. If the last device is not a Product Interface, refer to the last device’s instructionbulletin for termination instructions.

Terminating theCommunications Link

If a communications link contains only a single device, it must beterminated. If a link contains multiple devices, as in Figure 3-8, onlythe last device must be terminated.

NOTE

To connect the Product Interface as the last device on the PowerLogic communi-cations link, you’ll need the following items:

• One PowerLogic RS-485 Multipoint Communications Terminator (3090MCT-485). (This is not included with the Product Interface and must bepurchased separately).

• A five position terminal block—1 provided with each Product Interface.

• Belden 8723 or equivalent cable. (Not included).

The Product Interface has five switches on its faceplate. These switches are usedto set its baud rate, set its communications address, specify the transformer type,and reset the Product Interface. Figure 4-1 shows the switch locations. This chapterdescribes the purpose and use of each switch. A label on the side of the ProductInterface also shows the switch locations and their functions.

The Product Interface must be reset each time a change is made to the address, baudrate, or transformer type switch settings. There are two ways to reset the ProductInterface: Hardware Reset, and Software (remote) Reset.

To perform a hardware reset, press the Reset button located on the front of theProduct Interface. (See Figure 4-1). For instructions on performing a software resetusing PowerLogic software, refer to the instruction bulletin accompanying thesoftware.

RESETTING THEPRODUCT INTERFACE

Reset the Product Interface after changing a switch setting. If youchange a switch setting and do not press the Reset button, theProduct Interface will not use the new switch setting.

The Product Interface baud rate must be set to match the baud rate of the otherdevice(s) on the PowerLogic communications link. All devices on the PowerLogiccommunications link must be set to the same baud rate. For example, if two CircuitMonitors and one Product Interface are daisy-chained to a PNIM, both CircuitMonitors, the Product Interface, and the PNIM port must be set to the same baudrate.

The baud rate switch is located on the front of the Product Interface. (See Figure4-1). The baud rate switch settings are clearly identified on a label on the side ofthe Product Interface. Table 4-1 repeats the baud rate switch settings.

To set the baud rate, complete the following steps:

1. Insert a miniature, flat-bladed screwdriver into the arrow in the center ofthe baud rate switch.

2. Rotate the switch until the arrow points to the number that corresponds tothe desired baud rate. For example, to select 19200 baud, rotate the arrowto switch position 5.

3. Press the Reset button. This forces the Product Interface to use the newbaud rate setting.

NOTE: The Product Interface can also be reset by issuing a reset commandusing PowerLogic application software. For instructions on performing asoftware reset using PowerLogic software, refer to the instruction bulletinaccompanying the software.

Any single PowerLogic communications link can support up to 32 individualdevice addresses. For example, a single PowerLogic communications link couldhave 30 Circuit Monitors and 2 Product Interfaces. Because multiple devices canshare a single communications link, each device on the communications link mustbe assigned a unique communications address. The communications address isused by PowerLogic software and hardware products to locate a specific device onthe link.

Each Product Interface on a communications link must be assigned a communica-tions address in the range 1-32. When choosing an address for a Product Interface,consider the following points:

• Each device on the communications link must be assigned a uniqueaddress. For example, a Circuit Monitor and a Product Interface must notbe assigned the same address.

• Each PowerLogic communications link must have one device whoseaddress is “01.”

- If a communications link contains several daisy-chained ProductInterfaces (and no other PowerLogic devices), one Product Inter-face must be assigned the address “01.”

- If a communications link contains only one PowerLogic device, aProduct Interface, its address must be “01.”

The Product Interface’s communications address is set using two ten positionrotary switches located on the front of the Product Interface. (See Figure 4-1). Thelower address switch sets the ones digit. The higher address switch sets the tensdigit. To set the address, complete the following steps:

1. Insert a miniature, flat-bladed screwdriver into the arrow in the center ofthe ones switch.

2. Rotate the switch until the arrow points to the desired number.

3. Insert a miniature, flat-bladed screwdriver into the arrow in the center ofthe tens switch.

4. Rotate the tens switch until the arrow points to the desired number.

5. Press the Reset button. This forces the Product Interface to use the newaddress switch setting.

NOTE: The Product Interface can also be reset by issuing a reset commandusing PowerLogic application software. For instructions on performing asoftware reset using PowerLogic software, refer to the instruction bulletinaccompanying the software.

The XFMR TYPE switch, located on the front of the Product Interface, is used tospecify the type of transformer being monitored. A label on the side of the ProductInterface shows the switch position that corresponds to each transformer type.Table 4-2 repeats this information.

To set the transformer type switch, complete the following steps:

1. Insert a miniature, flat-bladed screwdriver into the arrow in the center ofthe XFMR TYPE switch.

2. Rotate the switch until the arrow points to the number that corresponds tothe correct transformer type. (See Table 4-2).

3. Press the Reset button. This forces the Product Interface to recognize thenew switch setting.

Note: The Product Interface can also be reset by issuing a reset commandusing PowerLogic application software. For instructions on performing asoftware reset using PowerLogic software, refer to the instruction bulletinaccompanying the software.

SETTING THETRANSFORMER TYPE

Double-check the XFMR Type switch setting. The switch must beset to match the type of transformer being monitored, for theProduct Interface to operate properly.

Before starting the Product Interface, review Chapter 3 and Chapter 4. Verify thatall external wiring is connected according to color codes. Inspect for stray wires andshort conditions. Check the baud rate and address settings. Be sure that the ProductInterface baud rate matches the baud rate of all other devices on the PowerLogiccommunications link. Verify that the address of the Product Interface is unique.Verify that the XFMR TYPE switch is in the correct position.

After verifying proper installation and setup, apply control power to the ProductInterface. The “DC OK” LED on the front of the enclosure should light indicatingthat the Product Interface is receiving adequate power. If the green LED does notlight, re-check the control power wiring. Be sure that the Product Interface isreceiving 120 VAC power. Refer to Chapter 5 - Maintenance and Troubleshoot-ing for troubleshooting tips.

The Product Interface provides two user-definable parameters called the label andnameplate. The label is a four character alpha-numeric string. The PowerLogicProduct Communications Software and other PowerLogic products display thelabel to help identify the device being viewed. The default label is “XFMR.”

The nameplate is a 16 character alpha-numeric string. The PowerLogic ProductCommunications Software and other PowerLogic products display the nameplateto help identify the device being viewed. For example, a typical nameplate mightbe “USS1 XMFR TEMP” indicating that the data being viewed is from thetransformer in Unit Substation 1. The default nameplate is “Transformer Temp.”

The label and nameplate are set using PowerLogic application software. Refer tothe software instruction bulletin for instructions on setting these values.

Appendix A – Register Listing

Each Product Interface has an identical set of storage registers. Table A-1 providesa listing of the registers. The table has three column headings: PIF Reg, R/W, andDescription. The column headings are described below.

PIF Reg - This column shows the Product Interface register number.

R/W - An R is shown in this column if the register can only be read, butnot written. If the register can be read and written, R/W is shownin this column.

Description - This column provides a description of the register contents.

• None of the R/W registers are saved when power to the Product Interface is lost.

• All non-supported registers return a value of zero when read. A write to theseregisters does nothing.

• Product Interface register 237 is a command register that allows the user to resetthe Product Interface by writing to the register with bit 5 set to 1. (This isequivalent to writing a decimal 16). This performs the same function aspressing the Reset button on the front of the Product Interface.

All PowerLogic devices are equipped with RS-485 communications. This RS-485standard allows up to 32 devices to be daisy-chained to a single communicationsport. For example, up to 32 Circuit Monitors can be connected to the top RS-422communications port of a PowerLogic Network Interface Module (PNIM). When1 to 16 PowerLogic devices are connected to a single communications port, themaximum length of the communications link, that is the distance from thecommunications port to the last PowerLogic device on the chain, is 10,000 feet.When more than 16 PowerLogic devices are connected to a single communicationsport, the maximum length of the communications link changes in relation to thebaud rate. This is necessary to insure accurate communications at high rates ofspeed (up to 19,200 baud). The table below shows the maximum distancesrecommended at varying baud rates.
