Electronic Overload Module Settings

NOTICE

ALWAYS make sure that the electronic overload module supplied with the control box is set to the correct amperage. This overload module 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. ALWAYS check the nameplate on the pump to determine the required amperage settings for the overload module.

CB200 Control Box Old Style Electronic Overload

Module

There are two dials on the Electronic Overload Module (Figure 14) that require setting before the pump can be used with the control box.

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

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

Full Load Current (FLC) Amps Dial Setting

1.Set the FLC (A) dial pointer (Figure 14) to 10.5. This setting represents the running amps of the pump. This information can be located on the pump's nameplate.

Class Dial Setting

1.Depending on the application, Set the CLASS dial pointer (Figure 14) to either HAND (manual) or AUTO.

2.There are 3 groups of numbers on the CLASS dial that range from 10 to 30. These numbers represent the trip class of the thermal overload device.

3.Set the CLASS dial pointer to position 10. This setting controls the reset function only. It does not affect the ability of the pump to run with or without float switches.

Reset Operation

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

MODE 1

When the CLASS dial on the electronic overload module is in the HAND position (manual) the reset button (Figure 15) on the front of the control box must be pushed to reset the unit (restore power) in the event of an overload.

MODE 2

When the CLASS dial on the electronic overload module is in the AUTO position (automatic mode) the unit will automatically be reset in the event of an overload

NOTICE

The CB200 Control Box (old style) is shipped from the factory with the CLASS dial set to the HAND position.
