4)
Reset pushbutton input, external device monitoring (EDM)
R1 Test pulse output
Y1 Application diagnostic output (NC)
Y2 Application diagnostic output (reset required)
A1 Voltage supply 24 V DC
A2 Voltage supply 0 V DC
1)
The enabling current paths must be supplied by the same voltage supply.
2)
The enabling current path and external device monitoring (EDM) must be wired within the control cabinet.
3)
With single-channel base device: Connect jumper between I1 and I2.
4)
•
Use w
ith restart interlock, with external device monitoring (EDM): Connect the N/C contacts of the
actuators between voltage supply U
v
, the N/O contact of the reset pushbutton and S1.
•
Use with restart interlock, without external device monitoring (EDM): Connect the N/O contact of
the reset pushbutton between S1 and voltage supply U
V
.
•
Use without restart interlock, with external device monitoring (EDM): Connect the N/C contacts of
the actuators between R1 and S1.
•
Use without restart interlock, without external device monitoring (EDM): Connect R1 and S1 with a
wire jumper.

T
o protect and increase the service life of contact outputs, equip all connected loads
with varistors or RC elements. The response times will increase depending on the sup‐
pressor used.
