8 Fault messages and alarms
Data cable
faulty Communication between master and slave
interrupted. Check the patch cable and replace, if
necessary
Synchronization
failed Slave device switched off or communica-
tion between master and slave interrupted Check plug connection of patch cable
or voltage supply
M/S incompatible
#0002...0008 - Master and slave are incompatible
- Different power controller types
used (max. load current, load volt-
age and subordinate control loop (if
applicable) do not match)
Use same power controller types with
same software versions.
#0002 Different device software versions Update devices to same device soft-
ware versions
v Service hotline
#0003 VDN numbers of devices do not match Master/slave operation not possible
#0006 Different nominal voltages (device types) of
master and slave device. Master/slave operation not possible
v Chapter 1.3 "Order details"
#0007 Different nominal currents (device types) of
master and slave device.
#0008 Set subordinate control loop of the master
is not compatible with that of the slave de-
vice. Change subordinate control loops of
both devices to U or U

v Chapter 6.1 "Detection of load
faults"
Slave: Limit value
Min. value reached The value has gone below the set limit val-
ue for the min. alarm at the slave Check why the value has gone below
the limit value.
Slave: Limit value
Max. value reached The set limit value for the max. alarm has
been exceeded at the slave Check why the limit value has been ex-
ceeded.
Slave: Fault at
connected load Break or short-circuit of a load resistor.
v Chapter 6.1 "Detection of load
faults"
Replace defective heating elements.
Slave:
Blown fuse
(red LED fuse is lit) 1. Semi-conductor fuse defective
v Chapter 8.2 "Replacing a defec-
tive semi-conductor fuse"
2. No voltage at terminal U1 - Check wiring
- Check the line fuse for the load
circuit
Slave:
