WARNING: Multiple Safety Devices
When two or more safety devices are used, each device must be individually actuated, causing a
STOP or open-contact condition, then reset/rearmed and the Safety Module reset (if using manual
reset mode). This allows the monitoring circuits to check each device and its wiring to detect faults. Fail-
ure to test each device individually in this manner could result in undetected faults and create an
unsafe condition which could result in serious injury or death.

Periodic Checkout Procedure

The functioning of the Safety Module and the device(s) connected to it must be verified on a regular periodic basis to ensure proper
operation (see also the machine manufacturer’s recommendations).

1. With the machine running, cause the safety device to generate a STOP or "open-contact" state (e.g., actuate the E-stop switch to

open its contacts). Verify that the machine stops.

2. Reset or otherwise cause the safety device to reach an ON or "closed-contact" state. Verify that the machine does not restart.
3. If using manual reset mode, close and then open the reset switch within 3 seconds. Verify that the machine can be restarted by

normal initiation.

4. If more than one safety device is series-connected to the Safety Module, run the above checkout procedure individually for EACH

device.

Repairs

Do not attempt any repairs to the Module. It contains no field-replaceable components. Return it to the factory for warranty repair
or replacement by contacting Banner Factory Application Engineering. They will attempt to troubleshoot the system from your description
of the problem. If they conclude a component is defective, they will issue a return merchandise authorization (RMA) number for your
paperwork and give you the proper shipping address.
Pack the Module carefully. Damage that occurs in return shipping is not covered by warranty.

CAUTION: Abuse of Module After Failure
If an internal fault has occurred and the Module will not reset, do not tap, strike, or otherwise attempt to
correct the fault by a physical impact to the housing. An internal relay may have failed in such a man-
ner that its replacement is required.
If the Module is not immediately replaced or repaired, multiple simultaneous failures may accumu-
late such that the safety function can not be guaranteed.
