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)

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