Connection of Reset Switch
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 8 to 12V dc at 10 to 15 milliamps. As shown in
the hookup drawings, the reset switch connects between Safety Module terminals S33 and S11.
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. See warning below.
Automatic Reset Mode
The Safety Module may be configured (via hookup) for automatic reset. If no MSC contacts are monitored, install a
jumper between terminals S33 and S34. The Safety Module will reset (and its outputs energize) as soon as the
switch returns to its armed (closed-contact) position.
Automatic reset is useful for some automated processes. However, if automatic reset is used, it is necessary to
provide a means of preventing resumption of hazardous machine motion, until an alternate reset procedure
is performed. The alternate procedure must include a reset/restart 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. See Warning below.
NOTE: The minimum amount of time required for the Module to be in a STOP or OFF 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.
8
The reset switch must be accessible only from outside, and in full view of, the hazardous area. Reset
switches must also be out of reach from within the safeguarded space, and must be protected against
unauthorized or inadvertent operation (e.g., through the use of rings or guards). If any areas are not visible from
the reset switch(es), additional means of safeguarding must be provided.
Failure to do so could result in serious bodily injury or death.
U.S. and international standards require that a reset routine be performed after clearing the cause of a stop condition
(e.g., arming an E-stop button, closing an interlocked guard, etc.). Allowing the machine to restart without ac-
tuating the normal start command/device can create an unsafe condition which could result in serious injury
or death.
