Measurement Accuracy
1.
When extending or connecting the thermocouple lead wire, be sure to
use compensating wires that match the thermocouple types.
2.
When extending or connecting the lead wire of the platinum resistance
thermometer, be sure to use wires that have low resistance and keep
the resistance of the three lead wires the same.
3.
Mount the product so that it is horizontally level.
4.
If the measurement accuracy is low, check to see if input shift has
been set correctly.
Waterproofing (Not applicable to the E5CC-U/
E5DC/E5DC-B.)
The degree of protection is as shown below. Sections without any
specification on their degree of protection or those with IP
@
0 are not
waterproof.
Front panel: IP66, Rear case: IP20, Terminal section: IP00
When waterproofing is required, insert the Waterproof Packing on the
backside of the front panel. Keep the Port Cover on the front-panel
Setup Tool port of the E5EC/E5EC-B/E5AC/E5EC-T/E5AC-T
securely closed. The degree of protection when the Waterproof
Packing is used is IP66. To maintain an IP66 degree of protection, the
Waterproof Packing and the Port Cover for the front-panel Setup Tool
port must be periodically replaced because they may deteriorate,
shrink, or harden depending on the operating environment. The
replacement period will vary with the operating environment. Check
the required period in the actual application. Use 3 years or sooner as
a guideline.
Operating Precautions
1.
When using self-tuning, turn ON power for the load (e.g., heater)
at the same time as or before supplying power to the Digital
Temperature Controller. If power is turned ON for the Digital
Temperature Controller before turning ON power for the load, self-
tuning will not be performed properly and optimum control will not
be achieved.
When starting operation after the Digital Temperature Controller
has warmed up, turn OFF the power and then turn it ON again at
the same time as turning ON power for the load. (Instead of turning
the Digital Temperature Controller OFF and ON again, switching
from STOP mode to RUN mode can also be used.)
2.
Avoid using the Digital Temperature Controller in places near a
radio, television set, or wireless installing. These devices can
cause radio disturbances which adversely affect the performance
of the Controller.
Others
1.
Do not Connect or disconnect the Conversion Cable connector
repeatedly over a short period of time.
The computer may malfunction.
2.
After connecting the Conversion Cable to the computer, check the
COM port number before starting communications. The computer
requires time to recognize the cable connection. This delay does
not indicate failure.
3.
Do not connect the Conversion Cable through a USB hub. Doing
so may damage the Conversion Cable.
4.
Do not use an extension cable to extend the Conversion Cable
length when connecting to the computer. Doing so may damage
the Conversion Cable.
5.
Wiring
When linking the units together, connect the power cable only to
the unit at the left end of the linkage block. Incorrect wiring can be
shorted inside the unit resulting in damage to the unit. Do not
perform crossover wiring between each linkage block, or to
another device. This could result in a breakdown or incorrect
operation.
6.
When N units are linked together, the inrush current will be equal
to N times that for 1 unit. Be sure to use the external fuse with the
appropriate fusing characteristics, and the breaker with the
appropriate tripping characteristics to ensure that the fuse does
not melt and the breaker is not activated due to the inrush current.
The inrush current per Unit is 30 A or less.
7.
Do not remove the connector cover from connectors that are not
to be linked. The connector covers have been mounted on the
product during shipment.
8.
Do not add or separate the units during power-on.
Mounting
Mounting to a Panel
E5GC
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 E5GC into the mounting hole in the panel.
3.
Use two Mounting Adapters, either on the top and bottom or on the
right and left.
4.
Push the Adapters from the terminals up to the panel, and
temporarily fasten the E5GC.
5.
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.
