code
lt.AC Motor overload
Device off Reduce the load by reducing the speed.
Overloads are especially liable to occur with
high-viscosity media and at high speeds.
Oht1 Overtemperature Device off Switch the unit off and allow it to cool down,
try reducing the load or the operating cycle.
OI.AC Overcurrent at the frequency Device off Reduce the load by reducing the speed. If this
inverter error appears even when idling with no load,
the frequency inverter is defective. Consult
the Service Engineer.
OU Overvoltage at the frequency Device off Check the mains power cable values and the
inverter power supply.
Note: High-frequency noises during operation of the T 65 digital ULTRA-TURRAX ® may to some extent originate from the frequency
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 ® unit.
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
® Service Department.
