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.
