close as possible to the motion-causing device.
Example: If you have a relay coil that in turn energizes a motor starter and you
cannot disconnect the motor wires, open the circuit at a point between the motor
starter and the relay contact.
WARNING
POSSIBLE UNEXPECTED MACHINE MOTION
During all testing, always disconnect all devices that, when energized,
might cause machine motion.
Failure to observe this precaution can cause equipment damage or
personal injury.
Powering Up
When you apply power to the system, the module status LED should illuminate,
indicating that your module is receiving power and has completed its onboard
self-test. If the LED does not illuminate after several seconds, your module is not
functional. Discontinue testing until you can get the LED to illuminate.
The most probable reasons for the LED not illuminating are:
•
The SLC 500 system is not receiving power from its power supply.
•
The rack slot where your module is located is defective.
•
Your module is defective.
Interpreting The
LED Indicators
Your module has nine LEDs: eight channel status LEDs (numbered 0–7 for
channels 0–7, respectively) and one module status LED.
