FF**
No synchronisation, pilot beam is obstruct-
ed.
Free up the pilot beam or readjust
the light curtain.
15, 45
Leakage of data in safety light curtain.
Encode anew, if necessary contact
technical support.
18, 48, 17, 47
Influence through ambient light, other sen-
sor, overmodulation (emitter too close to
receiver) or wrong coding.
Remove receiver from the cone of
light of the interrupting sensor or en-
code light curtain and set up new.*
19, 49
Leakage of data in safety light curtain or
wrong coding.
Encode anew, if necessary contact
technical support.
1A, 4A
Leakage of data in safety light curtain or
wrong coding.
Encode anew, if necessary contact
technical support.
1B, 4B
Connection to the contactor not duly, con-
tactor switches to slow, contactor monitor-
ing activated by mistake.
Contactor and cabling control.
Push enter button receiver.*
1C, 4C
Connection to the contactor not duly, con-
tactor monitoring activated by mistake.
Contactor and cabling control.
Push enter button receiver.*
1D, 4D
Connection to slave savety barrier has
broken down.
Check connection to the slave, press
the enter button on the receiver.
1F, 4F
Positive short at output, connection be-
tween the two outputs or excessive capaci-
tive load.
Eliminate short circuit *
20, 50
Mistake at output.
Contact technical support.*
22, 52
Short-circuit to ground at output or wrong
coding.
correct short-circuit to ground,
encode anew, if necessary contact
technical support *
23, 53
Working resistance not duly or wrong
coding.
Encode anew, if necessary contact
technical support.*
06
Leakage of data in safety light curtain.
Contact technical support.
FE**
Occurs during coding only.
Stop coding
* The error reset is executed by switching off the supply voltage of the receiver
** Error LED doesn’t shine
Do not operate in case of indeterminate malfunctioning
The machine must be shut down if the error cannot be unequivocally clarified or reliably eliminated.
