Access guarding
Detection of a person’s body on entry into the danger zone is
required.

AOPD response time
Time between penetration/entry into the active protective field of
the AOPD and when the OSSDs actually switch off.
AutoReset
When an error indication occurs, caused, for example, by faulty
external wiring, the AOPD attempts to start again. If the error no
longer exists, the AOPD returns to the normal state.
Contactor monitoring
(EDM)
The contactor monitoring monitors the normally closed contacts
of downstream positive-guided contactors and relays.
Danger zone guarding
Requires detection in the foot/leg area
EDM
External Device Monitoring
FC
Feedback circuit for EDM

Point of operation
guarding
Requires finger, hand or arm detection
RES
Start/REStart interlock.
Scan
All beams, beginning with the synchronization beam, are pulsed
by the transmitter in cycles one after the other.
SD4
SOLID-4 consisting of transmitter and receiver
SD4R
SOLID-4 Receiver
SD4R-E
SOLID-4 Receiver with selectable start/restart interlock and con-
tactor monitoring function (EDM)
SD4T
SOLID-4 Transmitter
SingleScan
A switch-off is made if a beam is interrupted in the first scan of the
Light Curtain.
SOLID-4E
SOLID-4 consisting of SD4T Transmitter and SD4R-E Receiver
Start/
restart interlock
(RES)
RES prevents automatic start after the supply voltage has been
turned on and after the protective field has been penetrated/
entered.
TC1/TC2
Transmission channel 1 and transmission channel 2
