Digital (Enhanced) Overhead Stirrer
7.Motor protection and overload
protection
Overhead Stirrer works continuous, the motor current is
electronically limited to achieve security stall and overload
protection. When a fault occurs, the security circuit
immediately switches off motor to stop running, while the
overload protection light on the control panel flashes.
• Starts overload protection
- When the setting speed value does not match the
current medium viscosity, starts overload protection.
- When the motor output shaft is stuck, motor
protection starts.
• Solutions
- When the setting speed value does not match medium
viscosity that caused overload protection, should be
first pressing speed control button to stop stirring
function. Restart stirring after lowered setting speed
value. If overhead protection continues starting, then
repeat the process and gradually reduce the speed.
- When the setting speed value does not match medium
viscosity that caused overload protection, should be
first pressing speed control button to stop stirring
function, remove the block material, and then re-set
original setting speed value to start stirring function.
The overhead protection still continues starting if the above
method used, please contact manufacturer/supplier.
8.Faults
• Instrument can not be powered ON when start stirring
function.
- Check whether the power cable is connected.
• Speed cannot reach set point
- The setting speed value does not match the current
medium viscosity, please reduce speed then re-start.
• Stirring function suddenly stop
- Power/overload protection light changed to red, value
setting/display area shows“Er 03” or “Er 04”,
indicate the current failure is“motor protection” or
“
overload protection”.
- Refer to Chapter 7 for the solutions of motor
protection and overload protection.
If these faults are not resolved, please contact manufacturer/
supplier.
