6.4 DIP switches for setting the operating mode

Located on the right side of the housing are six DIP switches.
S1 «ON» safety output - combined function (OUT1, OUT2: CH1 + CH2)
«OFF» safety output - separated function (OUT1: CH1; OUT2: CH2) (factory setting)
S2 «ON» auxiliary output - combined function (AUX1, AUX2: CH1 + CH2)
«OFF» auxiliary output - separated function (AUX1: CH1; AUX2: CH2) (factory setting)
S3 «ON» Mode auxiliary output AUX1: RL
«OFF» Mode auxiliary output AUX1: RLU (factory setting)
S4 «ON» Mode auxiliary output AUX2: RL
«OFF» Mode auxiliary output AUX2: RLU (factory setting)
S5 «ON» auxiliary output AUX1 and AUX2 flash on RLU
«OFF» auxiliary output AUX1 and AUX2 do not flash on RLU (factory setting)
S6 «ON» Auxiliary output AUX1 and AUX2 are active in the idle state on RLU
«OFF» Auxiliary output AUX1 and AUX2 are inactive in the idle state on RLU (factory setting)

7. Operating modes

7.1 Automatic reset

(S11 S12 bridged)
Following rectification of a fault in a sensor circuit or after a power failure, the switching unit automatically
re-enables the output.
7.2 Error lock - manual rese
(S11 S12 not connected)
Following rectification of a fault in a sensor circuit or after a power failure, the switching unit does not re-
lease the output(s) until contacts Z1 and Z2, 500 ms after the elimination of the disruption, are closed with
a button. An automatic restart is thereby rendered impossible. Permanent bridging of contacts Z1 Z2 does
not result in an automatic reset.

7.3 Auxiliary output undelayed (RLU)

(S3 = «OFF» or S4 = «OFF»; S5 = «OFF»)
In this operating mode, the corresponding auxiliary output is activated without delay if any error is signalled
on the respective channel. The auxiliary output can be toggled between normally closed contact and normal-
ly open contact with S6 („ON" = normally closed contact), whereby the output is always inactive while the
switching unit is in a power-free state.
