Periodic Checkout

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 (for example, actuate the E-stop

switch to open its contacts). Verify that the machine stops as expected.

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 the reset switch for approximately ¼ second and then open it. 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 this Banner device; it contains no field-replaceable components. Contact the Banner Application
Engineers, who will attempt to troubleshoot the system from your description of the problem. If they conclude that a component is defec-
tive, they will issue an RMA (Return Merchandise Authorization) number for your paperwork, and give you the shipping address to return
the device to Banner for warranty repair or replacement as needed.

Important: Pack the Banner device carefully. Damage that occurs in return shipping is not covered by war-
ranty.

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.

Output relay contact voltage 1V to 150V ac/dc: Cat-
egory III
Output relay contact voltage 151V to 250V ac/dc:
Category II (Category III, if appropriate overvoltage re-
duction is provided, as described.)

Input Requirements: Safety Input Switch

2-Channel (contacts) hookup: 10 to 20 mA steady
state at 12V dc
NOTE: Inputs are designed with a brief contact-clean-
ing current of 100 mA when initially closed.
Solid-State Dual Channel hookup: 5 to 20 mA steady
state at 18 to 28V dc sourcing ( PNP), < 2 mA leakage
current
Single-Channel hookup: 40 to 100 mA at 24V ac/dc ±
10%; 50/60 Hz

Input Requirements: Reset Switch

20 mA at 12V dc, hard contact only

Minimum OFF-State Recovery Time

250 ms (When used with the AG4 Safety Laser Scan-
ner, the “Restart delay time after PF release” must be
configured for 280 ms or greater.)
