1 Overview 1.2. The CH Breaker Gateway The CH Breaker Gateway is designed to allow CPC’s family of site controllers to interface directly with CutlerHammer Pow-R-Command PRC100 breaker control panels (equipped with PRC100MOD System Controllers) to activate and deactivate loads. A Pow-R-Command™ breaker panel features remotely controllable circuit breakers, each of which may be flipped from OFF to ON and from ON to OFF by commanding the PRC100MOD System Controller.
3 Power Wiring 3.1. CH Breaker Gateway Power Wiring Input Voltage 24VAC, Class 2, 50/60Hz Power 5VA Table 3-1 - Gateway Power Requirements The Gateway requires 24VAC power from a Class 2 center-tapped transformer. Figure 2-1 - Gateway Board Mounting Dimensions The Gateway should be mounted in an environment with ambient temperature between -40°F and 150°F, with a non-condensing relative humidity between 5% and 95%.
4 Networking 4.1. Connecting the CH Breaker Gateway to the Breaker Panels (Figure 4-2). PRC100MOD boards have no on-board termination and must be terminated with a 150-ohm resistor across the + and - terminals (Figure 4-2). TERMINATION TERMINATION The Cutler-Hammer breaker panels connect to the Gateway by MODBUS network connection. MODBUS is a two-wire, polarity-sensitive network physically similar to RS485.
4.1.3. Setting the NET Switches 1. Plug the HHT into the HHT jack. The PRC100MOD controller has a pair of switches that, when switched to the OFF position, breaks the MODBUS network connection. Verify that these switches are in the ON position as shown in Figure 4-4 to enable MODBUS communication. 2. From the opening screen, press the DOWN ARROW key to display the Board Addresses screen (Figure 4-6).

Setting the RS485 I/O Termination Jumpers As part of a site controller’s RS485 I/O (COM A or COM D) Network, a Gateway must be terminated if it is the end device of a daisy chain.
5.2.2. Adding Lighting Schedule Applications For each group of breakers to be controlled separately, set up a Lighting Schedule application from the Add New Application screen. 1. Add/Delete Application 2. Add New Application 3. DLOOK UP to select Lighting Control. Enter the number of desired applications in the How Many? field. If using an Einstein controller, from the Home screen or Enhanced Lighting Status screen, press ((Actions), (Control Appl Setup), and then (Add Control Application).
Figure 5-3 - Lighting Proof Setup Screen 5. Set Proof Type to ON Only. If the light circuit is read as open when it should normally be closed, the 16AI board will send a "fail" input relay to the controller. The Gateway proofs both ON and OFF so that the user can select the desired proof type as ALL Values, ON Only, or OFF Only. If any breaker within a group fails the proof, the entire group will fail the proof. 6.
HHT Keys Function F1 Home screen key F2 Quick access to status information OPTION: 0 1= STATUS 2= DIAGS 3= CONFIG Left and right arrow keys point to the desired field to be configured Up and down arrow keys scroll through all breakers on panel screens Cancel Enter Deletes number you have chosen and changes it to zero, and cancels overrides on selected field Figure 6-3 - Option Screen Option No. 1 Status information that can be overridden.
6.1.3. Status From the Option screen, select 1 for Status. The Status screen shows the status of the 48 groups and shows the ON or OFF state of each group and any proof failures (a proof failure is indicated by "*" after the ON or OFF state). Press the down arrow key to scroll through the groups. After the groups are displayed, continue pressing the down arrow key to see the ON or OFF state and any proof failures of each of the 48 breakers and all panels.

Appendix A: Worksheets Use the workspace below to assign breakers to groups. Refer to Table A-2 for group number board and point assignment.
16AI Address = ____ Fill in the Gateway 16AI board address that you set with the HHT. For groups 17-32, add 1; for groups 33-48, add 2. 8RO Address = ____Fill in the Gateway 8RO board address that you set with the HHT for Groups 1-8. For Groups 9-16, add 1; for 17-24, add 2; for 25-32, add 3; for 33-40, add 4; for 41-48, add 5.

Appendix B: Troubleshooting SYMPTOM Board Offline POSSIBLE PROBLEM I/O Network Problems SOLUTION Check wiring polarity. Verify the 485+ uses one color and the 485uses the other color throughout the network. Check each connector for any loose wires or frayed strands between connectors. Termination Jumpers Set Incorrectly Verify all three jumpers are set in the UP position if the board is at the end of a daisy chain, and that all other boards are not terminated (jumpers in DOWN position).
SYMPTOM HHT Home screen displays FAIL: I/O NET. POSSIBLE PROBLEM SOLUTION Communication has been lost between the site controller and the Gateway. Check I/O Net wiring. The Gateway is not configured with at least one group. It must be configured before the Gateway will communicate with the PRC100MODs on the MODBUS Network. If Receiver Bus Status LED is not blinking, assign at least one breaker to a group (1-16). If the Group number is 0 (zero), it is undefined.
