3084 !! Fault !! T-cooler 4 too low Flt>T-Cool.4 t.lo Temperature at dissipator 4 too low (cut-off at -5° C).
Heat up the operation environment;
3085 !! Fault !! T-cooler 5 too low Flt>T-Cool.5 t.lo Temperature at dissipator 5 too low (cut-off at -5° C).
Heat up the operation environment;
3094 Fault T-rectifier too low Flt>T-rect.t.low mean Temperature of the dissipator of the rectifier (top) too low (no tripping with
-5°C). Heat up the operation environment.
3095 Fault T-rectifier too high Flt>T-rect.t.high mean Temperature of the dissipator of the rectifier too high (cutoff temperature
depending on the capacity). Cool down the operation environment; reduce
the load; clean the air filter; recheck the fans of the devices. For devices
with 12 pulses or more: maybe the rectifier is overloaded an asymmetric
current. Measure the input currents at the mains side with a tong-test
instrument and contact our service station.
3096 Fault T-cabinet too high Flt>T-cab.t.high mean Temperature in the cabinet too high (cutoff with 55°C). Cool down the
operation environment; reduce the load; clean the air filter; recheck the
fans of the devices. In case of water-cooled devices: flow and return are
possibly mixed up.
3100 Fault Overvoltage Flt>Overvoltage - Voltage in intermediate circuit too high. Line voltage too high: reduce the
line voltage; extreme regenerative operation: set slower braking time or
add a brake transistor/resistor; extremely fast braking time: set slower
braking time.
3101 Fault Undervoltage Flt>Undervoltage mean Voltage in intermediate circuit too low. Line
voltage failing totally: reconnect
the line voltage; failure of a phase: recheck the line voltage in all three
phases; fuse defective: replace the fuse.
3103 Fault Earth fault Flt>Earth fault - Earth fault at output side of motor or in motor supply line. Repair the earth
fault; if necessary, contact our service station.
3104 Fault S7 inactive Flt>S7 inactive - 1. If you have not installed any board I/O -A95 in your inverter, and you do
not wish to use function "Safe torque off" or "ATEX motor temperature
monitoring", then switch S7 on board CB08, -A1 must be closed.
2. If you have installed a board I/O -A95 in your inverter, then contact a
service station or the factory.
3. When checking the "Safe torque off" function you obtain this fault when
the 2nd safety circuit at -X2:24 responds. A board I/O 3 or 4 is installed.
Switch S3 on board I/O DI/DO is closed, and therefore the two-
torque off" is activated per hardware. Parameter "P-
= X2:20" and therefore set to
single circuit. Depending on the requirements
of your specific application, you must set the parameters as well as also
switch S3 to single or two-circuit trip.
4. Board PTC thermistor evaluation is not installed: Switch S12 on –A95
board I/O DI/DO must be closed. If, in this case, switch S12 is open, then
also this fault is output. (NOTICE: safety-related function).
