Safety Controller SK 31
English
Versions and mechanical mounting
Version SK 31-31
Polycarbonate-enclosure with 1xM12 and 2xM16 cable glands for on wall mounting in harsh
environments.
The safety controller is to be fixed professionally to a suitable mounting place. After removing the
enclosure-cover, the enclosure can be fixed with four screws.
The installation position of the safety controller is not important, but to prevent infiltrating humidity
through the cable glands, the enclosure should be installed in such a way that the cable glands point
downwards.
Version SK 31-33
Version with snap-on holder for 35 mm DIN rail mounting in the cabinet.
Initial Operation
Requirements
•
If a voltage supply of 12-24V AC/DC is used, it must correspond with the requirements for the
functional safe voltages with a safe separation.
•
Cables outside the cabinet must be protected accordingly.
•
The specified degree of protection (IP-classification) for the safety controller is only guaranteed,
if the cables are inserted and fixed correctly into the cable glands, and the enclosure-cover is
fixed appropriately.
Electrical Connection
•
Connect the 12-24V AC/DC voltage supply to the clamps
12-24V AC/DC,
or 230 V AC voltage
supply to the clamps
PE-L1-N
•
Connect the PSS (edge, mat or bumper) to the clamps
X1/X2
•
Connect the to be monitored control circuit to the clamps
13-14
•
Connect the test-signal, which is provided by the machinery control system, to the clamps
Test-Signal
and select the signal form by using the S1 DIP-slide switch.
After the successful initial operation, the safety outputs 13-14 are activated (relay contact „closed“).
Operating the PSS causes the relay output contact 13-14 to be opened.
