Se� ng the operati ng mode via DIP switches
Located underneath the opening on the right side of the housing are
six DIP switches. Factory setti ngs are underlined.
S1 Test while voltage is applied (Off )/ missing at T1 T2 (On)
S2 Automati c reset (Off ) / error lock with man. reset (On)
S3 Auxiliary relay functi on: RL (On) / RLU (Off )
S4 Auxiliary relay fl ashes on RLU (On) / does not fl ash (Off )
S5 Auxiliary relay responds to CH1 and CH2 (On) / only to CH1 (Off )
S6
Auxiliary terminal is closed in the idle state (On) / open (Off )
Automati c reset (factory se� ng of S2 = "Off ")
Upon recti fi cati on of a fault in the sensor circuits or aft er a power failure,
the ELMON relay 34-32 automati cally closes relay contacts
13 14
.
During a fault, the corresponding LEDs CH1 / CH2 illuminate constantly.
Error lock with manual reset ( S2 = "On")
Upon recti fi cati on of a fault in the sensor circuit or aft er a power failure, the ELMON relay 34-32 does not
close output terminals 13 14 again unti l contacts Z1 and Z2, 500 ms aft er the eliminati on of the disrupti on,
are bridged with a butt on. An automati c restart is thereby rendered impossible. Permanent bridging of
contacts Z1 Z2 is not possible and is detected by the test.
Aft er the sensor is again released, the corresponding LEDs CH1 / CH2 fl ash unti l a man. reset is performed.
During a fault, the corresponding LEDs CH1 / CH2 illuminate constantly.
Auxiliary relay undelayed RLU (factory se� ng S3 = "Off ")
In this operati ng mode, the auxiliary relay contact 31 32 is acti vated if any error is signalled. The auxiliary relay
contact can be toggled between normally closed contact and normally open contact with S6 ("On" = normally
open contact), whereby the contacts are always open while the switching unit is in a power-free state.
Errors in channel 2 are only taken into account if S5 is in switch positi on "On" (factory setti ng of S5 = "Off ").
Auxiliary relay undelayed RLU fl ashing ( S3 "Off " , S4 = "On")
With
S4
, fl ashing of the relay can be acti vated in synch with the LEDs.

Auxiliary relay delayed RL ( S3 = "On")
In this operati ng mode, the auxiliary relay contact 31 32 is acti vated with a delay of approx. 0.5 second and
then remains acti ve for max. 3 seconds if an error is signalled. The auxiliary relay contact can be toggled
between normally closed contact and normally open contact with S6 , whereby the contacts are always open
while in a power-free state.
CH2 is only taken into account if S5 is in switch positi on "On" (factory setti ng of S5 = "Off "). S4 must be in the
"Off " switch positi on (factory setti ng); otherwise, the auxiliary relay is permanently inacti ve.
