Banner ES-FA-6G Safety Module - Manual (Page 11)

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 con-
tacts).
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 elements 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. 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.
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.
Specifications
Supply Voltage and Current
AI-A2: 115V ac (model ES-UA-5A) or 230V ac (model
ES-VA-5A) ±15% , 50/60Hz
BI-B2: 11V dc – 27.6V dc
Power consumption: approx. 4W/7VA
The Safety Module should be connected only to a SELV (safety
extra-low voltage, for circuits without earth ground) or a PELV (pro-
tected extra-low voltage, for circuits with earth ground) power sup-
ply.
Supply Protection Circuitry
Protected against transient voltages and reverse polari-
ty
Overvoltage Category
Output relay contact voltage of 1V to 150V ac/dc: cate-
gory III
Output relay contact voltage of 151V to 250V ac/dc:
category III, if appropriate overvoltage reduction is pro-
vided (see Overvoltage Category III Installations).
