V1.04/EN/00561071 [Thyristor Power Switch TYA 201]
Cause
- 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)
Different device software versions
VDN numbers of devices do not match
Different nominal voltages (device types) of
master and slave device.
Different nominal currents (device types) of
master and slave device.
Set subordinate control loop of the master
is not compatible with that of the slave de-
vice
Reminder that "manual" Teach-In has been
configured but not yet executed.
The value has fallen below the selected
limit value for the min. alarm at the slave
The selected limit value for the max. alarm
has been exceeded at the slave
Break or short-circuit of a load resistor.
v Chapter 6 "Special device func-
tions"
1. Semiconductor fuse defective
2. No voltage at terminal U1
Thyristor defective
Thyristor defective
Device temperature is higher than 100 °C
(Excess temperature)
8 Error messages and alarms
Remedy
Use same power controller types with
same software versions.
Update devices to same device soft-
ware versions
v Service hotline
Master/slave operation not possible
Master/slave operation not possible
v Chapter 1.3 "Order details"
Change subordinate control loops of
both devices to U or U
Perform Teach-In
v Chapter 6 "Special device func-
tions"
Check why the value has fallen below
the limit value.
Check why the limit value has been ex-
ceeded.
Replace defective heating elements.
v Chapter 8.2 "Replacing a defec-
tive semiconductor fuse"
- Check wiring
- Check the wire fuse for the load
circuit
The device must be returned to JUMO
for repair.
h Return the device
The device must be returned to JUMO
for repair.
h Return the device
- Ensure adequate ventilation or
provide for additional cooling
- Reduce load current
- Use power controller with high-
er maximum load current
