9.3 Remedy
Fault conditions are indicated by flashing the LEDs. Some errors are displayed through
periodic flashing (see table); with other errors it is possible to establish an error code
through the number of flashes.
Error Cause Remedy
Safety switch does not re­
act, LED "Device" does not
light Supply voltage missing/too
low Check supply voltage and apply 24 V
"Safety Gate" LED flashes a
code and "Device" LED
flashes red see section Error codes see section Error codes
"Device" LED illuminates
red Internal error Please contact Pilz
"Input" LED flashes yellow,
only one safety output
switches Only one channel of the in­
put circuit is open (partial
operation) Open both channels of the input circuit and
close them again
Signal output does not
switch when actuator is en­
gaged, "SafetyGate" LED
does not light up Actuator not detected Insert actuator as far as it will go
Solenoid does not switch Supply voltage or voltage
for solenoid operation is too
low, error in the wiring
}
Check voltages and apply 24 V, check wir­
ing,
}
Increase voltage for solenoid to increase
tolerance,
}
reduce cable run,
} Use cable with a greater conductor cross
section
Solenoid does not switch,
"SafetyGate" LED does not
light up Actuator not detected Insert actuator as far as it will go
Safety outputs do not switch Escape or auxiliary release
pin is not correctly in posi­
tion
}
Check whether the LED "Lock / Area Safe"
flashes red
}
Position the escape or auxiliary release pin
as far as it will go
}
Perform reset
"Safety Gate" LED lights up
and guard locking element
is engaged, but the outputs
are not switching. Wrong actuator, e.g. 1.1­
coded actuators with 2.2­
coded safety switch Insert correct actuator
Error codes
Error codes are issued after 9ß0 seconds at the latest at the LED "Safety Gate". The num­
ber of LED flashes corresponds to the error code. The error code consists of one digit. (4 x
flashing: error code 4). The flashing sequence is constantly repeated and separated from
each other by longer periods.
