SK 34 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. 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)
S3 Auxiliary relay function: RL (On) / RLU (Off)
S4 Auxiliary relay flashes on RLU (On) / does not flash (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)
Automatic reset (factory setting of S2 = "Off")
Upon rectification of a fault in the sensor circuits or after a power failure,
the SK 34 automatically closes relay contacts 13 14.
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 SK 34 does not close output
terminals 13 14 again until contacts Z1 and Z2 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.
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.
Auxiliary relay undelayed RLU (factory setting S3 = "Off")
In this operating mode, the auxiliary relay contact 31 32 is activated 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 position "On" (factory setting of S5 = "Off").
Auxiliary relay undelayed RLU flashing (S3 "Off" , S4 = "On")
With S4, flashing of the relay can be activated in synch with the LEDs.
Auxiliary relay delayed RL (S3 = "On")
In this operating mode, the auxiliary relay contact 31 32 is activated with a delay of approx. 0.5 second and
then remains active 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 position "On" (factory setting of S5 = "Off"). S4 must be in the
"Off" switch position (factory setting); otherwise, the auxiliary relay is permanently inactive.
