MODE SETTING
ELECTRICAL SHOCK
Remove power from FF-SR Series control modules
and machine during installation and before setup.
Failure to comply with these instructions could
result in death or serious injury.
To set the desired mode of operation, remove the
front panel (see figure 7). Refer to the back of the
front panel for switch setting options (see figure 8).
Set switches as required, then replace front panel.
S1 AND S2 SWITCHES
(Refer to the important warnings on page 6.)
This module contains two internal switches (S1 and
S2) that are used to set various modes of operation.
This feature ensures application flexibility.
Switches S1 and S2 are used to select automatic
start and manual start with or without cross fault
detection.
Switch S1 is used to select an operating mode for
cross fault detection between the two inputs.
Cross fault monitoring must be used when two
independent safety inputs are provided to this
module to increase the overall safety level of the
solution (see typical application examples).
Switch S2 is used to select automatic start or
manual start. Terminals S33 and S34 must be
connected for automatic start to function.

To gain access to the two internal switches, it is not
necessary to remove the terminal blocks. Just unclip
the front panel as shown in figure 7.

ELECTRICAL INSTALLATION
Multiple wiring configurations are possible for the
FF-SRS5925 dual channel emergency stop module.
General guidelines are provided because there are
various ways to interface the module to machine
control circuitry. Refer to the important warnings
(page 6) and the application examples (pages 7
through 9).
SAFETY CONTROL MODULE DAMAGE
Do not supply any current/voltage to the FF-
SRS5925 safety module control inputs.
inputs receive their voltage (24 Vdc under a 40 mA
current) from external power via pins A1 and A2.
Failure to comply with these instructions will
result in product damage.
LED INDICATORS
The FF-SRS5925 module has three green LED status
Panel
indicators (Power, K1 and K2) as illustrated below.
The Power LED indicates power is applied to the safety
control module. Illuminated K1 and/or K2 LED's
indicate(s) that the corresponding internal safety relay is
energized. Both K1 and K2 relays must be energized
to have the normally open contacts 13/14 and 23/24 in
a closed position. If one of the safety relays de-
energizes, the normally closed contact will close.
