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
SRD5985 Safety door monitor module. General 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
(page 6).
FUNCTIONAL DESCRIPTION
The module operates in an
accepts immediate input from the safety device (safety
switch).
If the module receives input (between S13/S14 and
S23/24) from two safety position switches that are
monitoring door closure, and this occurs in less than three
seconds (assuming the external monitoring loop circuitry
(Y1/Y2) is closed), the two normally open contacts of the
module (13/14 and 23/24) will close.
When the door opens, the two normally open contacts
(13/14 and 23/24) will open relaying the emergency stop
condition to the machine control circuitry to arrest
dangerous motion and/or remove power.
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-SRD5985 Safety
door monitor module. If multiple safety contacts are used in
parallel with one load, the maximum admissible current can
be increased.
