ELECTRONIC OVERLOAD UNIT SETTINGS

ElectronicOverloadUnit:Alwaysmakesurethat theelectronicunitsuppliedwiththecontrolboxisset to the correct amperage.This overload unit must MATCH the amperage requirements of the pump motor.

Using an electronic overload unit with incorrect settings may result in serious damage to the pump. Refer to the Pump Amperage Requirements Table (Table 7), for the correct overload amperage settings.

There are two dials on the Electronic Overload Unit (Figure 9) that require adjustment to meet the amperage requirement of the pump motor in use.

These dials are located on top of the overload unit and are labeled CLASS and FLC (A).

Use a phillips-head screw driver to adjust the dials to the correct settings.

FLC (A) Dial Setting

1.Set the FLC (A) dial pointer (Figure 9) to the correct amperage for the pump motor in use. Use Table 7, to determine the correct amperage setting.

ClassDialSetting

1.Set the CLASS dial pointer (Figure 9) to the HAND position 10. This controls the reset function only. It does not affect the ability of the pump to run with or without float switches.

RESETOperation

This electronic control unit has two modes of reset.The modes are defined as follows:

MODE 1

WhentheCLASSdialontheelectronicoverloadmodule isintheHAND position(manual)theresetbutton(Figure10)onthefrontofthecontrol box must be pushed to reset the unit (restore power) in the event of anoverload.

Figure 10. Control Box Reset Button

MODE 1

WhentheCLASSdialontheelectronicoverloadmoduleisintheAUTO position (automatic mode) the unit will automatically be reset in the event of an overload

NOTE

All Multiquip control boxes should have the CLASS dial set to the HAND position 10.
