8.2 Integral System Diagnostics (ISD)
The LED indication of the safety-monitoring modules shows the
different switching conditions and errors. The following tables show the
different switching conditions.
Tables switching condition indication
Diagnostic LED System condition
The LED is green. Enabling circuit Y14 und Y 24 "high"
LED flashes green Enable delay time running
The LED is yellow At least one safety guard open
LED flashes yellow The feedback circuit is open.
The enabling input X4 is open.
Table error indications
Indication
(orange) LED
Error Cause
1 impulse Error safety
guard 1 Defective supply
voltage lead, defective
switch, erroneous
fitting of the switch;
switch only partially
actuated* for at least 5
s; cross-wire short
2 impulses Error safety
guard 2 Refer to error
safety guard 1
3 impulses Error safety
guard 3 Refer to error
safety guard 1
4 impulses Error safety
guard 4 Refer to error
safety guard 1
5 impulses Enabling outputs
Y14 and Y24 Cross-wire short;
Short-circuit
6 impulses Additional
transistor outputs
Y1-Y5 Short-circuit
7 impulses Interference
signals at the
inputs Too high capacitive or
inductive interference
at the inputs or the
supply voltage lead, no
safe evaluation
8 impulses Feedback circuit Defective feedback
message of the
external contactors,
erroneous wiring of the
feedback circuit
* Partial actuation: position of the switch, in which only one contact was actuated.
Deleting the error message
The error message is deleted once the fault has been rectified and
after the connected switches have been actuated to check the various
functions (open and then close the safety guard).
