ES-UA-5A and ES-VA-5A E-Stop Safety Modules
4. If more than one safety device is series-connected to the Safety Module, run the above checkout procedure
individually for EACH device.
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 manner that its replace-
ment 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.
Do not attempt any repairs to the Module. It contains no field-replaceable components. Return it to the fac-
tory for warranty repair or replacement: Contact Banner Factory Application Engineering at the address or the
numbers listed on 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 a return merchandise authorization (RMA) number
for your paperwork, and give you the proper shipping address.
Pack the Module carefully. Damage which occurs in return shipping is not covered by warranty.

Specification
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 (protected extra-low
voltage, for circuits with earth ground) power supply.
Protected against transient voltages and reverse polarity
Output relay contact voltage of 1V to 150V ac/dc: category III
Output relay contact voltage of 151V to 250V ac/dc: category III, if appropriate
overvoltage reduction is provided (see
11).
2
4 normally open (N.O.) output channels and 1 normally closed (N.C.) auxiliary output
Each normally open output channel is a series connection of contacts from two
forced-guided (mechanically linked) relays, K1-K2. The normally closed Aux. output
channel is a parallel connection of contacts from two forced-guided relays, K1-K2.
Contacts: AgNi, 5 µm gold-plated
Low Current Rating: The 5 µm gold-plated contacts allow the switching of low
current/low voltage. In these low-power applications, multiple contacts can also be
