Initial Checkout Procedure; Periodic Checkout Procedure - Banner ES-UA-5A Instruction

CAUTION . . . Disconnect Power Prior to Checkout
Before performing the initial checkout procedure, make certain all power is disconnected from the machine
to be controlled.
Dangerous voltages may be present along the Safety Module wiring barriers whenever power to the machine
control elements is ON. Exercise extreme caution whenever machine control power is or may be present.
Always disconnect power to the machine control elements before opening the enclosure that houses the
Safety Module.
1. Remove power from the machine primary control elements.
2. Ensure the safety device is in a STOP or "open-contact" state (e.g., actuate the E-stop switch to open its contacts).
3. Apply power to the Safety Module at terminals A1 and A2 or B1 and B2. Verify that only the Input Power indicator
is ON. If either input channel 1 or input channel 2 indicators are ON at this point, disconnect the input power and
check all wiring. Return to step 2 after the cause of the problem has been corrected.
4. Reset or otherwise cause the safety device to reach an ON or "closed-contact" state (e.g., arm the E-stop switch
to close its contacts).
5. Manual Reset mode: Ch1 and Ch2 indicators should be flashing. Close and reopen the Reset switch.
6. Verify that the Ch1 and Ch2 indicators both come ON. If only one indicator comes ON or if any indicator is
flashing, refer to the Troubleshooting section for more information. Return to step 2 after correcting the problem.
7. Cause the safety device to generate a STOP or "open-contact" state (e.g., actuate the E-stop switch to open its
contacts).The Ch1 and Ch2 indicators should turn OFF simultaneously. If either indicator remains ON, disconnect
the input power and check all wiring. Return to step 2 after the cause of the problem has been corrected. Refer
to the Troubleshooting section for more information.
8. If more than one safety device is series-connected to the Safety Module, run the above checkout procedure
individually for EACH device.
9. Close and secure the enclosure in which the Safety Module is mounted. Apply power to the machine control ele-
ments and perform the Periodic Checkout Procedure.
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. Failure to test each device in-
dividually in this manner could result in undetected faults and create an unsafe condition which could result
in serious injury or death.
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 2 seconds. Verify that the machine
can be restarted by normal initiation.
