Safety Relay
Setting the operating mode via DIP switches
7.
Located underneath the opening on the right side of the housing are six
DIP switches, of which only switches 1 and 2 are assigned a function.
Factory settings are underlined.
S1
Test while voltage is applied (Off) / missing at T1 T2 (On)
S2
Automatic reset (Off) / error lock with man. reset (On)
Automatic reset (factory setting of S2 = "Off")
Upon rectification of an actuation or fault in the sensor circuits or after a power failure, the ELMON rail 35
automatically closes relay contacts 13 14 or 23 24.
During a fault, the corresponding LEDs CH1 / CH2 illuminate constantly.
Error lock with manual reset (S2 = "On")
Upon rectification of a fault in the sensor circuit or after a power failure, the ELMON rail 35 does not close
output terminals 13 14 or 23 24 again until contacts Z1 and Z2, 500 ms after the elimination of the disruption,
are bridged with a button. An automatic restart is thereby rendered impossible. Permanent bridging of
contacts Z1 Z2 is not possible and is detected by the test.
Actuation of the reset push-button always results in the resetting of both safety
related channels!
After the sensor is again released, the corresponding LEDs CH1 / CH2 flash until a man. reset is performed.
During a fault, the corresponding LEDs CH1 / CH2 illuminate constantly.
8. Commissioning
8.1 Prerequisites
•
When supplying via terminals B1 and B2, the voltage must comply with the requirements for Protective
Extra Low Voltage (PELV).
•
Cables installed outdoors or outside of the switching cabinet must be protected appropriately.
