ware versions
v Service hotline
#0003 VDN numbers of devices do not match Master/slave operation not pos-
sible
#0006 Different nominal voltages (device types)
of master and slave device.
Master/slave operation not pos-
sible
v Chapter 1.3 „Order specifi-
cations“
#0007 Different nominal currents (device types)
of master and slave device.

Slave: limit value
Min. value reached
The value has gone below the set limit
value for the min. alarm.
Check why the value has gone
below the limit value.
Slave: limit value

The set limit value for the max. alarm. has
been exceeded at the slave.
Check why the limit value has
been exceeded.
Slave: fault at
connected load
Break or short-circuit of a load resistor.

(red LED fuse is lit)
1. Semi-conductor fuse defective v Chapter 8.2 „Replace defec-
tive semi-conductor fuse“
2. No voltage at terminal U1 - Check wiring
