To satisfy the requirements of Safety Category 4 of ISO 13849-1(EN 954-1), the Master
Stop Control Elements must each offer a normally closed, forced-guided monitor contact.
One normally closed monitor contact from each Master Stop Control Element is wired in
series to the feedback input (S33/S34 auto reset, S11/S33 manual reset; see Figures 2
and 3). In operation, if one of the switching contacts of either master stop control element
fails in the shorted condition, the associated monitor contact will remain open. Therefore,
it will not be possible to reset the E-Stop Safety Module. If no MSC-monitor contacts are
monitored in auto reset, a jumper must be installed between terminals S33 and S34 (see
Figures 2 and 3). It is the responsibility of the user to ensure that any single failure will
not result in a hazardous condition and will prevent a successive machine cycle.
The hookup diagrams (Figures 2 and 3) show a generic connection of the E-Stop Safety
Module’s redundant output circuits to Master Stop Control Elements. A Master Stop Control
Element is defined as an electrically powered device, external to the E-Stop Safety Module,
which stops the machinery being controlled by immediately removing electrical power to the
machine and (when necessary) by applying braking to dangerous motion (reference ANSI
B11.19, section 5.2: “Stop Control”). This stopping action is accomplished by removing
power to the actuator coil of either Master Stop Control Element.
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 Figures 2 and 3, the Reset switch
connects between terminals S33 and S11 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.
The ES-FA-9AA module may be used also with automatic reset. If no MSC-monitor contacts
are monitored, a jumper must be installed between terminals S33 and S34 (see Figures 2
and 3). 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.
NOTE: The minimum amount of time required for the Module to be in a STOP or OFF
E-Stop Safety Module –

P/N 60606 rev. B
condition is 250 ms. This “recovery time” (OFF-state) is required for the internal
circuitry of the Safety Module to normalize, allowing a reliable reset to occur. A
lockout will occur if the Module is cycled too quickly. To clear the lockout, the
Module must be re-cycled, meeting the minimum OFF time requirements.

• Whenever two or more E-stop
• Also, when two or more E-stop
standards require that a reset 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.
switches 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.
