Self-test, duration approx. 10 s, is performed after the supply voltage

At least one door open

All doors closed, reset pushbutton no

All doors closed, reset pushbutton pressed
Commissioning

Ö 1 Hz o o
Teach-in process

Acknowledgment for successful teach-in
Fault indication
o o O
Internal device component failure or actuator in the response range for
le
ss than 0.5 s or inadmissibly high external interference (EMC)
Operating error
Ö 3× o O
Teach-in must be repeated. Possible causes:
•
24 V signal is present at the input of the reset pushbutton
(S) although automatic reset was taught in.
•
Closed function EDM (Y1/Y2) is present although no external
device monitoring was taught in (e.g. because the contactors was
open during teach-in).
•
DIP switch setting was changed without a new teach-in process.
•
Not all protective doors were closed during the teach-in process
that are to be monitored and which were selected at the DIP
switches.
•
Status change during the teach-in process
•
Shorting jumper at J1, J2 was connected with switched-on supply
voltage U
B
.
Ö 4× o O
EDM fault, malfunction of the monitored contactor. Possible causes:
•
A
ctuator was outside the response range only briefly (door open/
closed). The contactors did not drop out as a result (pay attention
to dropout times of the contactors).
•
Malfunction of the monitored contactor (EDM)
•
EDM was not connected when the evaluation unit was started.
Test mode
O o O
Test with closed door (TST = 24 V)
Meaning of symbols:
o = LED of
f
O = LED lit
Ö = LED flashing
Ö 3× = LED flashes three times
NOTE
Dis
plays other than those described here indicate an internal device fault. In this case, please contact your SICK
subsidiary.
