The MiniOCS keypad has “OK” and “RUN” indicators. These indicators are green LEDs that are built into
the keypad. When there are no errors present in the MiniOCS and the Self-Tests have “passed,” the
green “OK” LED illuminates. When the controller is running logic, the RUN LED illuminates. If the
controller is in the RUN mode with no logic loaded or if it is in the DO I/O mode, the RUN LED flashes.

Operation
When the MiniOCS unit first powers-up, it displays “MiniOCS Self-Test In Progress.”Next, the message
“MiniOCS Self-Tests In Progress...” appears. After the Mini displays this message, the unit performs tests
to examine the current state of the network. Four different scenarios can occur:
Scenario #1: No power is supplied to the CAN port. The message “No Network Power Network
Disabled” is displayed. Assuming the controller is configured to require the network, the OCS then
displays the message “Self-Tests Failed.” Also, there is a Fault Code of 80 displayed in “View OCS Info”
in the System Menu (see Chapter 3). The green “OK” light does not illuminate.
Scenario #2: No other units are on the CAN network (or this is the first device to power-up on the
network). The message "Waiting for Net: F1 = Disable Net" is shown. If another device is placed on
the CAN network, the message clears and operation continues. The message “Self-Tests Passed” is
displayed. The green “OK” light illuminates. If F1 is pressed the message “No Net Response Network
Disabled” appears and is followed by the message “Self-Tests Failed”. The green “OK” light does not
illuminate.
Scenario #3: If a unit powers-up and finds another unit with the same node number as itself, the display
shows "Duplicate ID Network Disabled". The network is disabled, and the unit displays the message
“Self-Tests Failed.” The green “OK” light does not illuminate.
Note: The ID checking works when one of two devices with the same ID is powered-up more than 1
second before the other. If both devices are powered-up at the same time, this method of
ID checking may not work. In this case, the Mini continues to check for duplicate IDs during operation.
Scenario #4: If a unit powers up and it has network power, and other units are powered up on the
network, the message “Self-Tests Passed” is displayed, and the green “OK” light is illuminated.
At any time, the Mini unit can be reset by pressing:

+ F1 + F2 (press the keys at the same time)
