REPLACEABLE OUTPUT BOARD DESCRIPTION
Output Board
The controller is supplied with an output board (relay, logic/SSR or triac)
installed. The output board is configured for the type of Main Control and
Alarm Output based upon the model number ordered. The output board is
field replaceable in many models. (For models where the output board is not
replaceable, the controller must be returned to the factory for output board
repair.) See Ordering Information, page 81, for available models.
Replacing Output Board
1. Remove the bezel assembly. (See Removing Bezel Assembly, page 3).
2. Lift up on the top bezel board latch while gently pulling out on the
bezel/display board assembly. Do NOT remove the display board from
the bezel.
3. Remove the output board by pulling it away from the other boards. Replace
the output board by aligning the board to board connector. Be certain the
connector is fully mated.
4. Connect the bezel/display board assembly by guiding the board ends into the
bezel latches. Slide the assembly on evenly until the display board connector
is completely engaged and bezel latches are fully seated onto the boards.
