ELECTRICAL INSTALLATION
ELECTRICAL SHOCK
Remove power from FF-SR Series control modules and
machine during installation.
Failure to comply with these instructions could result
in death or serious injury.
Multiple wiring configurations are possible for the
FF-SRE3081 extension
guidelines are provided because there are various ways
to interface the module to machine control circuitry. Refer
to the important warnings (page 5) and the application
examples (pages 6 through 7).

control module. General
FUNCTIONAL DESCRIPTION
This module receives two safety inputs between A1/A2
and A3/A4 from a connected safety device. Immediately,
the normally open safety contacts (13...73/14...74) will
close and the normally closed safety contacts (81/82) will
open.
If a safety device is actuated (an emergency stop
condition occurs), the normally open contact will open
immediately and the normally closed contact will close.
This emergency stop condition is relayed via the safety
contacts of the module to the machine control circuitry to
arrest dangerous motion and/or remove power.
FIG 7. BLOCK DIAGRAM
The normally closed contact of the extension module
(81/82) must be connected to the external loop monitoring
circuit of the connected safety device. This configuration
will ensure that the two safety relays in the extension
module are operating correctly.
One or more FF-SRE3081 Extension Modules or external
contactors with positively driven contacts can be used to
multiply the number of contacts of the FF-SRE3081
Emergency Stop Module. If multiple safety contacts are
used in parallel with one load, the maximum admissible
current can be increased.
