DIAGNOSTIC FUNCTION
Light Curtain operating status is visualized through a LED User Interface present on both the receiver and emitter
units. The figures show all LEDs signaling modes: OFF, ON, and BLINKING.
The operator can evaluate the main causes of the system stop or failure through the display and signaling LEDs.

F1: failure on
microprocessor
Internal Failure, check for operating con-
dition (see “Technical data” in Instruction
Manual)) and any cause of electrical
interference, power cycle the ESPE
F2: failure on
optics
Failure on optic scan, check for any cause
of optical and electrical interference,
power cycle the ESPE
F3: failure on
EDM
Failure on EDM, check connection to
relay (see “EDM function” in Instruction
Manual), then power cycle the ESPE
F12: cascade
failure
Failure on cascade communication,
check cascade connection or terminator
cap fixing (see "
F13: failure on
restart
Failure on Restart function, check for
Restart Button connection and any cause
of optical interference, then power cycle
the ESPE
F23: failure on
OSSDs
Failure on Safety Outputs, check for
proper connection (see "
) and any cause of electrical inter-
ference, then power cycle the ESPE
