Adjust motor current monitoring

The minimum and maximum motor current of the connected pumps is monitored:

• Minimum motor current monitoring
• The value is permanently stored in the switchgear: 300 mA or 10% of the set motor current.
• NOTICE! Monitoring can be disabled in Menu 5.69.
• Maximum motor current monitoring
• Adjust the value in the switchgear.
• NOTICE! Monitoring cannot be disabled!

Monitoring of the maximum motor current is carried out via electronic motor current monitoring.

The same potentiometers are used for switchgears up to 12 A and up to 23 A: scale 0 to 12. The following applies to the adjustment of the rated currents:

• Switchgears up to 12 A: The value corresponds 1:1 to the scale, e.g. 6 = 6 A. Maximum adjustable value: 12 A
• Switchgears up to 23 A: The value corresponds 1:2 to the scale, e.g. 6 = 12 A. Maximum adjustable value: 24 A

8	Potentiometer for motor current monitoring

Use a screwdriver to set the rated motor current at the respective potentiometer.

NOTICE! “0” setting on the potentiometer leads to an error when the pump is activated!

Precise adjustment of motor current monitoring can be performed during commissioning. During commissioning, the set and the actual rated motor current can be shown on the display:

• Currently set value of the motor current monitoring (Menu 4.25 – 4.26)
• Currently measured operating current of the pump (Menu 4.29 – 4.30)
