STEP 4. Install the CPU and Interface Boards (daughter boards)
IMPORTANT:
DO NOT CONNECT CONTROLLER TO POWER DURING FIRST-TIME INSTALLATION STEPS.
IF YOU ARE REPLACING A BOARD ON EXISTING SYSTEM, KEEP IT DISCONNECTED FROM THE POWER HARNESS
WHILE YOU ARE HANDLING THE BOARD OR WIRING/CONNECTING OTHER DEVICES.
4.1 Install the 635-CPU Board inside Controller
NOTE: if you have a pre-install process that allows you to preconfigure the CPU settings, you may do that before installing.
However, this requires you to know in advance what the field settings must be. This is helpful if you are repairing/replacing an
existing board. If you do not have a preconfigure process, you will program the board at a later step.
1.
Loosen the stand-offs and mount the Board (bracket) flush against the back wall of cabinet, in first slot.
DO NOT mount bracket on end of stand-off – See diagram below.
NOTE: Board installs with components facing down (or toward power supply).
2.
Tighten stand-offs on top of the bracket
,
to anchor the board firmly in position (see diagram cutaway below).
3.
Connect the Ribbon Cable
to the Data port (J8).
4.
Connect the Sense (Tamper) Connector to
(J7)
.
DO NOT CONNECT POWER HARNESS YET.
5.
Remove the paper strip
*
from the 3V lithium battery.
FYI - The paper strip shows the embedded
flash version
installed on the CPU from the factory.
If the field system
is running newer or older flash version, you must update the CPU to the field version.
Updating CPU Flash is
performed in a future step (before loading data to the board).
