Single Module System
Single Module Systems (SMS) comes standard with one Customer Contacts Interface Board and has an option for a second.
Paralleled System
Parallel System come standard with one Customer Contacts Interface Board in the Parallel Controller Cabinet and has an option for a second. Each MMU has the option of having a Customer Contacts Interface Board installed in each MMU also. There is limited input/output contact support when a Customer Contacts Interface Board is installed in an MMU.
Both
The purpose of the Customer Contacts Interface Board is to provide an isolated customer interface to the UPS1200 unit. There are six programmable output dry contacts for the customer to use. The alarm or condition on which the relay changes state is user selectable. The alarms or conditions is received by the Customer Contacts Interface Board over the Multi-drop network from the APC2 control Board.
In addition, there are six programmable isolated inputs to which the customer may connect alarms or status indicators. These relays are powered by an isolated +24VDC supply. The customer simply connects the input to an isolated dry contact. On a contact closure, the status is then relayed over the Multi-Drop to the APC2 for the appropriate action to be taken.
Custom messages may be programmed as well. The Instructions button on the User Interface has a list of programmable options for the input and output contacts of the Customer Contacts Interface Board.
From the Graphical User Interface on the front of the Controls cabinet, touch the "Instructions" button at the top right side of the Graphical User Interface. This selection brings up the Instructions screen on Graphical User Interface.
Touch the "Table of Contents" button at the bottom of the screen. This selection will bring up a list of help functions.
Touch the "User I/O Help" button to bring up the list of programmable options for the input and output contacts on the Customer Contacts Interface Board.

Multidrop Bus
The Customer Contacts Interface Board provides serial data over the UPS1200 Multidrop Bus. The Customer Contacts Interface Board functions as a slave on this bus, receiving commands from the APC-2 and responding with status information.
The Customer Contacts Interface Board has a jumper-selectable 100-Ohm terminating resistor for the Multidrop bus. Jumper JMP1 provides terminal resistance. There is also a switch that sets the Node ID. Set the Node ID for the Customer Contacts Interface Board and terminating resistor jumper to the settings on the following table.
| Customer Contacts Interface Board Multidrop Settings | |
|---|---|
| Node ID CCI #1 | 4 |
| Node ID CCI #2 | 5 |
| Terminating Resistor | JMP1 - Never installed |
Refer to Systems Operation, Testing and Adjusting, RENR7654, "Multidrop Network - Setup" for information on setting up the Multidrop Network.

Removal
- Perform steps in the Systems Operation, Testing and Adjusting, "Internal Component Preremoval Steps (Controls Cabinet)" in order to de-energize the system and gain access to internal components.
- Disconnect all connectors from the board. The connectors locations in the unit are labeled. Verify each connector to make sure that the label is present and legible.
Refer to Illustration 2.

Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. When not in use, keep the module in the static-shield bag. Follow these guidelines when you handle any module: Touch a grounded object to discharge static potential. Wear an approved wrist-strap grounding device. Do not touch the bus connector or connector pins. Do not touch circuit components inside the module. If available, use a static-safe work station. |
- Remove the cross head ground screw, labeled "J2", from the bottom right of the Board.
- Disconnect the five white plastic standoffs connecting the board to the left panel using the following method.
Note: The board must be removed from the stand-offs without bending the board.
- Pinch the head of each stand-off so that the board is not locked to the stand-off but is still attached to the stand-off.
- Remove the board by gently and evenly pulling the board from all stand-offs at the same time.

- Position the board in the cabinet over the five white stand-offs that are connected to the left panel.
- Push the board, gently and evenly, onto all the stand-offs simultaneously. Make sure all stand-offs are locked in place.
- Attach the cross head ground screw into the bottom right hole of the board labeled "J2".
- Plug the wire connectors into the correct connectors on the board. Check the labels on each connector for proper placement.
