5.2 Emergency stop function
The emergency stop impact button switches off the safety OSSDs
Release details of the emergency stop impact button are transmitted to
the control system via the response byte in the SD/FB protocol
The bit assignment in the SD/FB response byte is as follows:
Position 1: Emergency stop
• Unactuated
Authorised operation: Response bit 0 = 1
• Actuated
Switched off:
Response bit 0 = 0
5.3 Mode of operation of the safety outputs
The safety outputs of the emergency stop function can be integrated
directly into the safety-relevant part of the user control system for circuit
connection Actuation of the emergency stop impact button causes
immediate deactivation of the safety outputs
Any error that does not immediately affect the functionality of
the emergency stop function (eg ambient temperature too high,
interference potential at safety output, short circuit) will lead to a
warning message and delayed shut-down of the safety outputs
safety outputs are disabled if the error warning is active for 30 minutes
Once the error has been rectified, it can be acknowledged by actuating
and disengaging the emergency stop impact button The safety outputs
enable and allow a restart Error acknowledgement can be carried out
by setting / deleting bit 7 in the SD/FB query telegram
5.4 Function of the command and signalling devices
The non-safety signals of the command devices are transmitted to
the control system via the response byte in the SD/FB protocol The
Illuminated signals are controlled by the control system via the query
byte in the SD/FB protocol
The bit assignment of the SD/FB response byte / query byte is as follows:
Position 2:
Illuminated pushbutton, indicator lights, pushbutton and
mushroom pushbutton
LT, LM, DT, PT
• Pushbutton function NO contact Response bit 1 = 1
NC contact: Response bit 2 = 0
• Indicator lights

NC contact: Response bit 2 = 1
• Position 1
NO contact: Response bit 1 = 1
NC contact: Response bit 2 = 0
Maintained selector switch / spring-return selector switch,
3 positions:
WS3, WT3, WTS3

Query bit 5
5.5 Function of G24 indicator lamp
The G24 indicator lamp is controlled by the control system via the query
byte in the SD/FB protocol
The bit assignment of the query byte is as follows:
• G24
Red LED
Query bit 1
• G24
green LED
Query bit 2
