E-Stop Safety Module
Periodic Checkout Procedure
The functioning of the E-stop system must be verified on a regular periodic basis to
ensure proper operation (see also the machine manufacturer's recommendations).
Procedure:
1. With the machine running, engage the E-stop switch (open its contact). Verify that the
machine stops.
2. Return the E-stop switch to its closed-contact position. Verify that the machine does
not restart.
3. Close and then open the Reset switch (if using manual reset mode). Verify that the
machine can be restarted by normal initiation.
NOTE: If two or more E-stop switches are series-connected to one E-Stop Safety
Module, this test must be run individually for EACH switch.
NOTE: Do not attempt any repairs to the Emergency Stop Safety Module. It
contains no field-replaceable components. Return the Safety Module to the
factory for warranty repair or replacement.
If it ever becomes necessary to return an E-Stop Safety Module to the factory, please do
the following:
1. Contact the Banner Factory Application Engineering Group at the address or at the
numbers listed at the bottom of the back page. They will attempt to troubleshoot the
system from your description of the problem. If they conclude that a component is
defective, they will issue an RMA (Return Merchandise Authorization) number for your
paperwork, and give you the proper shipping address.
2. Pack the E-Stop Safety Module carefully. Damage which occurs in return shipping is
not covered by warranty.

switches are used, each switch must be
individually actuated (engaged), then re-
armed and the E-Stop Safety Module reset
(if using manual reset mode). This allows
the monitoring circuits to check each switch
and its wiring to detect faults. Failure to test
each switch individually in this manner
could result in undetected faults and
create an unsafe condition which could
result in serious injury or death.
If an internal fault has occurred and
the ES-...A-5A 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 manner that its
replacement is required.
If the Module is not immediately
replaced or repaired, multiple
simultaneous failures may accumulate
such that the safety function can not
be guaranteed.
To remove a terminal
block, insert a small
screwdriver into the slot
as shown, and pry to
loosen.
