A2
Chassis ground/N
13, 14; 23, 24
Relay enabling circuit, normally-open, undelayed
31, 32
Relay signaling circuit, normally-closed (enabling circuit status), undelayed
47, 48; 57,58
Relay enabling circuit, normally-open, delayed
61,62
Relay signaling circuit, normally-closed (enabling circuit status), delayed
73, 74
Relay signaling circuit, normally-open (feedback circuit fault)
T1, T2
Test outputs with pulsed test signals
T3
Test output with static test signal (+24 V DC)
1
Cascading input/normal switching duty
Y12, Y22
Sensor inputs, channel 1, channel 2
Y33
Start button (start after upwards and downwards edge)
Y34
Feedback circuit (checked only for "closed" to enable operation without feedback)

LEDs, keys and their meanings (undelayed and delayed)
Table 8-7
LEDs - undelayed and delayed enabling circuits
LED
Status
Meaning
Off
No / too low supply voltage or internal fuse tripped.
Green
Supply voltage in the permissible operating range
Flashing green
Self-test during restart
Yellow
Configuration mode DIP switch
Flashing yellow
Configuration error or
configuration mode for delay time
Green/yellow
flashing
Delay time changed
Device
Red
Device defective -> Replace device
Device faulty (e.g. due to electromagnetic interference)→ Press Reset
Off
Output passive
Green
Output active
OUT
Flashing green
•
OFF-delayed output, time running
•
RF not
"closed"
if start condition met (the SF LED also flashes)
Off
Input passive (or switch-on condition not satisfied)
Green
Input active
IN
Flashing green
Cross-circuit at the input, simultaneity of sensors not satisfied, wire breakage during safety
shutdown mat operation
Off
No group fault
Red
Group fault (wiring fault, cross-circuit, wire breakage in the case of safety shutdown
operation, configuration error) -> Eliminate the fault and press RESET
SF
Flashing red
Group fault (RF fault, simultaneity condition of the sensors not satisfied)
