7.2 Diagnostic information
Diagnostic Code
Cause
Remedy
FF**
No synchronisation,
pilot beam is obstructed.
Free up the pilot beam or readjust the light
barrier.
15, 45
Leakage of data in Safety Light Array
Encode anew, if necessary contact technical
support
18, 48, 17, 47
Influence through ambient light, other
sensor, overmodulation (Transmitter too
close to receiver) or wrong coding.
Remove receiver from the cone of light of
the interrupting sensor or
encode Safety Light Array and set up new. *
19, 49
Leakage of data in Safety Light Array or
wrong coding.
Encode anew, if necessary contact technical
support.
1A, 4A
Leakage of data in Safety Light Array or
wrong coding.
Encode anew, if necessary contact technical
support.
1B, 4B
Connection to the contactor not duly,
contactor switches to slow, contactor
monitoring activated by mistake.
Contactor and cabling control.
Push enter key receiver*
1C, 4C
Connection to the contactor not duly,
contactor monitoring activated by mistake.
Contactor and cabling control.
Push enter key receiver*
1D, 4D
Connection to slave safety barrier has
broken down.
Check connection to slave, press the enter
key on the receiver.
1F, 4F
Positive short at ouput, connection between
the two outputs or excessive capacitive
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, ancode
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 Array.
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
DANGER!
Do not operate in case of indeterminate malfunctioning.
The machine must be shut down if the error cannot be unequivocally clarified or reliably eliminated.
