ES-3Replacing the Power Supply Board

[1] Replacing the Power Supply Board
1. Remove the frame cover. (See the Sections D-1 & D-2
	"Removing the Frame Covers.")
2.	Remove all connectors CN-1, CN-2, CN-3 and CN-4 which are
	connected to the power supply board.
3.	Loosen the two screws which fix the power supply board to
	remove the board. (Fig. 1)
4.	Securely fix the brand new power supply board by using two
	fixing screws.
5.	Connect three connectors, CN-2, CN-3 and CN-4.
[2] Adjustment of Coil Current Value
1.	Connect the cables for measuring coil current between the
	female connector of the solenoid coil and the male connector
	(CN-1) on the power supply board, and then connect the
	cables to an ammeter. (Fig. 2)
2.	Turn on the power switch of the main unit, set the control unit

to the manual mode, set the load display to 4.0kg m, and start

the system.

3. Adjust the potentiometer (as shown in Figs. 3 and 4) on the

power supply board with a blade-head screwdriver so that the

coil current will be the value indicated on the workload unit

solenoid coil. (A clockwise turn will increase the current, while

a counter-clockwise turn will reduce the current.)

Example: When the indication is 630 as shown in Fig. 5, adjust the potentiometer so that the coil current value will be 630mA.

4. Upon completion of the adjustment, detach the cable for

measuring coil current, and connect the CN-1 connector
