Removing the Digital Temperature Controller from the case

E5GC

You can use the Y92F-55 Draw-out Jig to remove the interior body of

the Digital Temperature Controller from the case to perform

maintenance without removing the terminal wiring. This is possible

only for the E5GC. Check the specifications of the case and Digital

Temperature Controller before removing the Digital Temperature

Controller from the case.

1. Draw out the interior body from the rear case.

1. Slowly insert the Draw-out Jig into the Draw-out Jig insertion holes

laterally until it clicks into place. (There is a hole at both the top and

bottom.) (If you attempt to draw out the interior body of the Digital

Controller when only one hook is engaged, the Digital Controller

may be damaged.)

2. Pull out the Draw-out Jig together with the front panel. Do not pull

with excessive force. Slowly pull out the Digital Controller laterally.

(If you pull the interior body out at an angle, the Digital Controller

may be damaged.)

3. After the interior body is free from the rear case, support the

interior body with one hand and draw it out slowly in a horizontal

direction.

2. Insert the new interior body into the rear case.

1. When inserting the interior body back into the rear case, make

sure the PCBs are parallel to each other, mount the sealing

rubber, and press the interior body toward the rear case and into

position, making sure that the sealing rubber does not move.

2. When you press the Digital Controller into position, press down on

the rear case hooks so that the case hooks securely lock in place.

(There are rear case hooks at both the top and bottom of the rear

case.) If the Digital Controller is not correctly mounted into the rear

case, the rear case may not be waterproof. When inserting the

Digital Controller, do not allow the electronic components to touch

the rear case.

Removing the draw-out jig when only one hook is caught

in the draw-out jig insertion hole

1. Pull the Draw-out Jig slowly in the direction shown in the figure.

(This step is the same even if the other hook is caught.)

2. Confirm that the Draw-out jig is free of the Draw-out jig insertion

hole.

3. If the interior body separates from the rear case, slowly press the

interior body into the rear case in a horizontal direction.

If you do not follow the procedures above, the Digital Controller

may be damaged.

Precautions when Wiring

• Separate input leads and power lines in order to prevent external

noise.

• Use crimp terminals when wiring the screw terminal blocks.

• Use the suitable wiring material and crimp tools for crimp terminals.

• Tighten the terminal screws to a torque of 0.43 to 0.58 N·m.

The specified torque is 0.5 N·m for the E5CC-U.

Wire Size

Use the wire sizes and stripping lengths given in the following table.

• If you use crimp terminals, use the stripping length that is

recommended by the manufacturer of the crimp terminals.

• To reduce the affects of noise, use shielded twisted-pair cable for

the signal lines.
