Faults And Error Codes - IKA T 65 digital ULTRA-TURRAX Mode D'emploi

Faults on the T 65 basic ULTRA-TURRAX
Cause
Power supply failure
Stand not in position (if the
stand safety limit switch is
connected)
Overload
If none of these causes was the cause of the problem, a fault other than those described must have occurred and the unit must be
checked by an authorised person.
Error codes T 65 digital ULTRA-TURRAX
If a fault occurs with the unit, proceed as follows:
 Switch off the unit at the main switch (A)
 Carry out corrective measures
 Restart the device
All error codes are displayed with the legend "trip", i.e. the word "trip" is displayed alternating with the relevant error code.
Error Cause

Oht1 Overtemperature
OI.AC Overcurrent at the frequency

Note: High-frequency noises during operation of the T 65 digital ULTRA-TURRAX
inverter, depending on the design. They certainly do not indicate a defect within the unit.
Note: The green and red LEDs around the "Speed setting" rotary knob (E) are not relevant to the T 65 digital ULTRA-TURRAX
Any faults are shown exclusively on the display (F).
Note: If any error codes other than those listed above appear on the display please switch the unit off and on again at the main
switch (A). If the error code persists please contact the IKA
If the actions described fail to resolve the fault or another error code is displayed then take one of the following steps:
- Contact the IKA service department
®

Solution
Checking the power supply should be perfor-
med by authorised personnel.
Precautionary measure:
Check the power supply
Move the stand into position.
Precautionary measure:
Check the position of the stand
Remedy the overload, e.g.:
- the viscosity of medium is too high
- Solids jamming the stator/rotor
- Dispersing element defective (blocked).
Solution
Reduce the load by reducing the speed.
Overloads are especially liable to occur with
high-viscosity media and at high speeds.
Switch the unit off and allow it to cool down,
try reducing the load or the operating cycle.
Reduce the load by reducing the speed. If this
error appears even when idling with no load,
the frequency inverter is defective. Consult
the Service Engineer.
Check the mains power cable values and the
power supply.
