EATON A200 Size 5 Motor Controller

pop-up spring 

Under normal circumstances, no maintenance is required, just ensure that the spring is correctly seated on the molded crossbar assembly. If it accidentally falls off, you can use pointed pliers to clamp the front end of the spring, rotate the offset pin end to reduce the outer diameter, and then re insert it into the base hole.

Operating coil

When replacing the coil, it is necessary to check the part number, voltage, and frequency on the label. Commonly used coils are shown in Table IX, and coil data (typical values) are shown in Table X

Exchange suction VA: 1700 (surge)/180 (sealed)

DC suction VA: 600 (surge)/22 (sealed)

Sealing power: 32 W (AC)/20 W (DC)

Replacement steps:

Cut off the power supply between the controller and the coil.

Remove the coil lead wires.

Remove the arc extinguishing cover.

Gently lower the crossbar.

Remove the two mounting screws and take out the old coil.

Place the new coil and install the screws.

Reset the crossbar to the correct position.

Reinstall the arc extinguishing cover and tighten the bolts.

Connect the coil leads and manually check if the crossbar moves flexibly.

AC/DC coil conversion

If low drop voltage or ultra quiet operation is required, an AC/DC coil conversion kit can be selected. This kit rectifies AC control voltage into DC and needs to be used in conjunction with intermediate control relays. The conversion kit and corresponding control relay are shown in Table XI.

Recommended tightening torque (see Table XII):

Arc extinguishing hood screw: 90-100 lb in

Coil terminal screw: 15-18 lb in

Coil installation screw: 15-18 lb in

Static contact screw: 150-175 lb in

Power cord lug: 300-400 lb in

Screw for moving contact assembly: 55-65 lb in

Anchor mounting screw: 100-120 lb in

Fixed magnet mounting screw: 125-150 lb in
