• Whenever two or more E-stop switches
• Also, when two or more E-stop
routine be performed after returning the E-
stop switch to its closed-contact position
(when arming the E-stop switch). When
automatic reset is used, an alternate
means must be established to require a
reset routine, after the E-stop switch is
armed. Allowing the machine to restart
as soon as the E-stop switch is armed
creates an unsafe condition which could
result in serious injury or death.
are connected to the same E-stop Safety
Module, the contacts of both switches
must be connected together in series.
This series combination is then wired to
the respective Safety Module input.
Never connect the contacts of multiple
E-stop switches in parallel to the E-
stop Safety Module inputs; this defeats
the switch contact monitoring ability of
the Safety Module, and creates an
unsafe condition which could result in
serious injury or death.
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.

ANSI B11 and NFPA 79
standards require that a reset
Reset
The Reset Circuit switch can be any mechanical switch such as a normally open
momentary switch, or a two-position key switch. The Reset switch must be capable of
reliably switching 12 to 18V dc at 40 to 100 milliamps. As shown in Figure 2, the Reset
switch connects between terminals Y1 and Y2 of the Safety Module.
The Reset switch must be located outside of – and not be accessible from – the
area of dangerous motion, and must be positioned so that any area of dangerous
motion may be observed by the switch operator during the Reset procedure.
Model ES-FA-6G may be configured for automatic reset by replacing the Reset switch
with a jumper wire in the Y1-Y2 feedback/reset input circuit (see Figure 2). The E-stop
Safety Module will reset (and the outputs energize) as soon as the E-stop switch
returns to its closed-contact position.
The automatic reset mode is useful for some automated processes. However, if
automatic reset is used, it is necessary to provide an alternate means of preventing
resumption of hazardous machine motion, until an alternate reset procedure is
performed. The alternate procedure must include a Reset switch, located outside the
area of dangerous motion, which is positioned so that any area of dangerous motion
may be observed by the switch operator during the reset procedure.
The action of the Auxiliary Monitor Contact, 41-42, inversely “follows” the action of
output contacts 13-14, 23-24 and 33-34 when power is applied to the E-stop Safety
Module. The contact 41-42 is open when the three normally open output contacts are
closed, and vice versa. The 41-42 Auxiliary Monitor Contact is to be used only for
control functions that are NOT safety-related. A typical use is to communicate the
status of the Safety Module output to a programmable logic controller (PLC). The
switching capacity of the 41-42 Auxiliary Monitor Contact is 250V ac/dc maximum at
6 A maximum (see product specifications on page 10).
NOTE: The MSC Monitor Contacts must remain in a series connection betweet Y1
