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.
This module offers the possibility to function in the
automatic start mode or manual start mode. To set
the desired mode of operation, insert the start push-
button between terminals S33/S34 for manual start
mode or insert a jumper between X1/X2 for
automatic start mode to function (see table below)

ELECTRICAL INSTALLATION
Multiple wiring configurations are possible for the
FF-SRS5988 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-
SRS5988 safety module control inputs (S11/S12
S21/S22). These inputs receive their voltage (24
vdc under a 110 mA current) from external power
via pins A1/A2 or via A3(+)/A4(-)
•
Failure to comply with these instructions will
result in product damage.

FUNCTIONAL DESCRIPTION
In the manual start mode, the module accepts
input from the safety device (light curtain, safety mat,
safety switches, etc.) between S11/S12 and
S21/S23 after activation of the start push button
between S33 and S34. The two internal safety relays
(K2, K3) will then energize and the normally open
safety contacts (13/14...63/64) will close and the
normally closed contact (81/82) will open
In the automatic start mode, the module accepts
immediate input from the safety device (light curtain,
mat, safety switches, etc.) between S11/S12 and
S21/S23 (Y1 and Y2 are jumpered if external relay
monitoring is not needed). The two internal safety
relays (K2, K3) will then energize and the normally
open safety contacts (13/14...63/64) will close and
the normally closed contact (81/82) will open.
In either mode, if the safety device is actuated
(emergency stop condition occurs), the normally
open contact will open immediately and the normally
closed contacts 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.
INPUT SIGNAL SEQUENCE
•
The voltage at terminal S23 must be applied
before terminal S12, in order to let the automatic
start function work properly.
•
In the manual start mode the input signal
sequence order has no impact.
