Mounting Option Cards
Refer to the installation document that accompanies a specific option card for complete details. The following
procedure provides a basic set of steps.
Procedure 2
Mounting option cards on a JO-PC1 controller.
Step 1
Remove power
from the controller—see the previous
.
Step 2
Remove the cover. See
“Removing and Replacing the Cover,”
Step 3
Remove the battery and bracket assembly by taking out the four screws holding it in place, setting the
screws aside for later. Unplug the battery from the connector on the controller’s base board.
Step 4
Remove the blanking end plate for the slot you are installing the option card into.
(Retain the blanking plate in case the option card must be removed at a later date.)
Step 5
Carefully insert the pins of the option card into the socket of the appropriate option card slot.
The mounting holes on the option board should line up with the standoffs on the base board. If they
do not, the connector is not properly aligned. Press until the option card is completely seated.
Step 6
Place the custom end plate that came with the option card over the connector(s) of the option card.
Step 7
Plug the battery connector plug into the battery connector on the controller’s base board.
Step 8
Set the battery and bracket assembly back over the option card slots, with the mounting holes aligned
with the standoffs.
Step 9
Place the four screws through the battery bracket, end plates, and into the standoffs on the controller’s
base board. Using a screwdriver, hand tighten these screws.
Step 10
Replace the cover.
About Accessory Modules
The JO-PC1 controller has a 20-pin, right-angle, Euro-DIN connector that accepts custom-built accessory
modules. The connector provides power and signal lines to any connected modules, and is located on the end of
the JO-PC1 opposite to the option cards.
Warning
•
Power to the controller must be OFF when inserting or unplugging accessory modules.
Wait for all LED activity to stop (all LEDs to be off).
•
Also, do not connect live voltages to the inputs or outputs of an I/O module (JO-16 or JO-34)
while it is in an “un-powered state” before plugging the module into a JO-PC1.
Otherwise,
damage to the I/O module and/or the controller may result
!
