This circuit has redundancy in the emergency-stop control circuit and therefore offers the highest
possible safety level.

FUNCTIONAL DESCRIPTION:

After activation of the Emergency-stop push button, the K1 and K2 LED’s will turn OFF, indicating that the
two internal safety relays K1 and K2 are de-energized. The normally open safety outputs 13/14... 63/64 will
open.
There exist two different start modes:
Manual start mode
1. After  removing the stop condition, press and release the START push button to restart the safety control

module.

2. The K2 and K3 LED’s will turn ON indicating that the safety relays K2 and K3 are energized. The six

normally open safety contacts will close and the normally closed monitoring contact will open allowing the
machine to operate.

Automatic start mode
1.  After removing the stop condition, the safety control module will reset within 1 sec.
The K2 and K3 LED’s will turn ON indicating that the safety relays K2 and K3 are energized. The six
normally open safety contacts will close and the normally closed monitoring contact will open allowing the
machine to operate.

APPLICATION NOTES:

NOTE (A): 

Dual channel safety devices:

This may be an emergency stop push button in series with dual output safety switching devices (OSSD)
such as
- safety light curtains (FF-SB, FF-LS),
- safety mat (FF-SM),
- single beam (FF-SPS), modular safety light curtains (FF-SC),
- safety laser scanner (FF-SE),
- dual output safety limit or interlock switches (for example, 2CLS and GK, see fig. 12).

NOTE (B):

 Y1 and Y2 are jumpered if no external contactors have to be monitored

NOTE (C):

 Start mode:

Manual start mode: Insert start push-button between S33/S34; no jumper must be set between X1/X2
Automatic start mode: Insert jumper between X1/X2

IMPROPER AUTOMATIC START MODE IN PERIMETER GUARDING APPLICATIONS

•

 If the module is in the automatic start mode, another part of the safety control circuitry must keep the

latched function engaged.

Failure to comply with these instructions could result in death or serious injury.
