for illustration.
A maximum of four option boards can be used per unit, barring other restrictions. A four option board stack requires
four (4) M4x70 pan head screws.
A single option board stack requires four (4) M4x25 pan head screws.
STEP 1 – Standard 2A, (4) “OS” contacts (LCS/Main Board)
Connect to the control cover using (4) M4x8 pan head screws.
From the terminal block, connect 12-pin plug (Cable J1) to socket J5 on the main board.
STEP 2 – Option “OA”, 4-5A “R” contacts and (1) 5A MR (monitor relay); Digital Output board connection
Connect to the control cover using four (4) M4x25 pan head screws.
Ensure that jumper on the DO board is located in the 1-2 position. Connect 12-to-22 pin adapter to Cable J1 (12-pin
plug). Connect to the 22-pin socket J3 on DigOut board
NOTE: This will disable the digital relays on the main board. A keycode must be entered to restore them. Please contact
factory at 434-528-4400 for the keycode.
A shield is required to be installed between the digital output board and any adjacent boards.
STEP 3 - Option “OB”, 4-5A “R” contacts and (1) 2A MR (monitor relay ); Digital Output board connection and
2 – 2A “S” contacts
Connect to the control cover using four (4) M4x25 pan head screws.
Ensure that the jumper is located in the 3-4 position. Connect Cable J1 (12-pin) to socket J5 (12-pin) on the main
board. Connect cable J5 (22-pin) to socket J3 on DigOut board.
STEP 4 - Option “OC”, 8-5A “R” contacts and (1) 5A MR (monitor relay); 2 Digital Output boards connection
Connect to the control cover using four (4) M4x40 pan head screws.
Ensure that the jumper on DigOut board 1 is in the 1-2 position and the jumper on DigOut board 2 is in the 3-4
position. Connect the 12-22 pin adapter to Cable J1 (12-pin), then connect it to socket J3 (22-pin) of board 1. Connect
cable J5 to socket J3 of board 2.
STEP 5 – ANALOG OPTION BOARD CONNECTION (option)
Connect to the control cover using four (4) M4x25 pan head screws if one analog board is installed. Connect to the
control cover using four (4) M4x40 pan head screws if two analog boards are installed.
Ensure that jumpers 1 and 2 are in the same position. If there is only one board, both should be in the
1-2 position (Board 1). If there are two boards, the second board should have the jumpers in
2-3 position. Connect J8 (3-pin) cable to J3 of board 1. Connect J3 (4-pin) cable to J1 of board 2.
STEP 6 – MODBUS – DDC NETWORk BOARD CONNECTION
Connect to the control cover using four (4) M4x25 pan head screws if one DDC board is installed. Ensure that Jumpers
1 and 2 are both in the “A” position. Connect the J7 6-pin cable from the terminal block to socket J2.
STEP 7 – PROFIBUS-DP NETWORK BOARD CONNECTION
Connect to the control cover using four (4) M4x25 pan head screws if one Profibus-DP board is installed. Ensure that
both jumpers are in the “A” position. Connect the J7 6-pin cable from the terminal block to socket J8.
