Precautions During Operation - Omron E5CD-B-800 Series Instruction Manual

E5@D-800

Precautions during Operation

1. It takes approximately two seconds for the outputs to turn ON from
after the power supply is turned ON. Design the system (e.g.,
control panel) to allow for this delay.
2. Make sure that the Digital Temperature Controller has 30 minutes
or more to warm up after turning ON the power before starting
actual control operations to ensure the correct temperature
display.
3. Avoid using the Digital Temperature Controller in places near a
radio, television set, or wireless installing. The Digital Temperature
Controller may cause radio disturbance for these devices.

Mounting to the Panel (E5ED-800/E5ED-B-800)
1. For waterproof mounting, waterproof packing must be installed on
the Digital Temperature Controller. Waterproofing is not possible
when group mounting several Digital Temperature Controllers.
2. Insert the E5CD-800/E5ED-B-800 into the mounting hole in the
panel.
3. Push the Adapter from the terminals up to the panel, and
temporarily fasten the E5CD-800/E5ED-B-800.
4. Tighten the two fastening screws on the Adapter. Alternately
tighten the two screws little by little to maintain a balance. Tighten
the screws to a torque of 0.29 to 0.39 N·m.
Mounting the Terminal Cover (E5ED-800 only)
There are two models of Terminal Covers that you can use with the
E5CD-800.
Slightly bend the E53-COV23 Terminal Cover to attach it to the
terminal block as shown in the following diagram. The Terminal Cover
cannot be attached in the opposite direction. Or, you can use the E53-
COV17 Terminal Cover. Make sure that the "UP" mark is facing up,
and then attach the E53-COV17 Terminal Cover to the holes on the
top and bottom of the Digital Temperature Controller.

Drawing Out the Interior Body of the Digital
Temperature Controller to Replace It
You can use the Draw-out Jig to remove the interior body of the Digital
Temperature Controller from the case to perform maintenance
without removing the terminal leads. Use the Y92F-58 Draw-out Jig
for the E5CD-800 and the Y92F-59 Draw-out Jig for the E5ED-800.
Check the specifications of the case and Digital Temperature
Controller before removing the interior body from the case. (Drawout
is not possible on the E5@D-B-800.)
1. Draw out the interior body from the rear case.
1. Align the arms on the Draw-out Jig with the top of the front panel
on the Digital Temperature Controller and position it vertically.
(The Y92F-58 is shown in the figure.)

2. Align the hooks on the Draw-out Jig with the Draw-out Jig insertion
holes on the Digital Temperature Controller and slowly insert the
Draw-out Jig into the Draw-out Jig insertion holes laterally until it
clicks into place. (If you attempt to draw out the interior body of the
Digital Temperature Controller when only one hook is engaged,
the Digital Temperature Controller may be damaged.) (The Y92F-
58 is shown in the figure.)
