8 Fault messages and alarms
M/S incompatible
#0002...0008 - Master and slave are using different
versions of the software
- Different power controller types used
(max. load current, load voltage and
subordinate control loop (if applicable)
do not match)
Use same power controller types
with same software versions.
#0002 Different device software versions Ensure that devices are using the
same software versions
v Service hotline
#0003 VDN numbers of devices do not match Master/slave operation not possi-
ble
#0006 Different nominal voltages (device types) of
master and slave device. Master/slave operation not possi-
ble
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 device. 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 value
for the min. alarm at the slave Check why the value has gone be-
low the limit value.
Slave: limit value
min. value reached 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.
v Chapter 6.1 "Detection of load
faults"
Replace defective heating ele-
ments.
Slave:
blown fuse
(red LED fuse is lit) 1. Semi-conductor fuse defective
v Chapter 8.2 "Replacing a
defective semi-conductor
fuse"
2. No voltage at terminal U1 - Check wiring
- Check the line fuse for the
load circuit
Slave:
SCR breakage SCR defective The device must be returned to
JUMO for repair.
h Return the device
Slave: SCR
short circuit SCR defective The device must be returned to
JUMO for repair.
h Return the device
Slave: caution!
High temp. Device temperature is higher than 100 °C
(excess temperature) - Ensure adequate ventilation
- Reduce load current
- Use power controller with
higher maximum load current
