Digital Temperature Controllers
E5CN/E5CN-U
Precautions for Correct Use
Service Life
1.
Use the Temperature Controller within the following temperature
and humidity ranges:
Temperature: 10 to 55 C (with no icing or condensation)
Humidity: 25% to 85%
If the Controller is installed inside a control board, the ambient
temperature must be kept to under 55 C, including the
temperature around the Controller.
2.
The service life of electronic devices like Temperature Controllers
is determined not only by the number of times the relay is
switched but also by the service life of internal electronic
components. Component service life is affected by the ambient
temperature: the higher the temperature, the shorter the service
life and, the lower the temperature, the longer the service life.
Therefore, the service life can be extended by lowering the
temperature of the Temperature Controller.
3.
When two or more Temperature Controllers are mounted
horizontally close to each other or vertically next to one another,
the internal temperature will increase due to heat radiated by the
Temperature Controllers and the service life will decrease. In such
a case, use forced cooling by fans or other means of air
ventilation to cool down the Temperature Controllers. When
providing forced cooling, however, be careful not to cool down the
terminals sections alone to avoid measurement errors.
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 Temperature Controller so that it is horizontally level.
4.
If the measurement accuracy is low, check to see if input shift has
been set correctly.
Waterproofing
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: NEMA4X for indoor use (equivalent to IP66)
Rear case: IP20, Terminal section: IP00
(E5CN-U: Front panel: Equivalent to IP50, rear case: IP20,
terminals: IP00)
Operating Precautions
1.
It takes approximately two seconds for the outputs to turn ON
from after the power supply is turned ON. Due consideration must
be given to this time when incorporating Temperature Controllers
in a sequence circuit.
2.
When using self-tuning, turn ON power for the load (e.g., heater)
at the same time as or before supplying power to the Temperature
Controller. If power is turned ON for the Temperature Controller
before turning ON power for the load, self-tuning will not be
performed properly and optimum control will not be achieved.
3.
When starting operation after the 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 Temperature Controller OFF and ON again, switching from
STOP mode to RUN mode can also be used.) Avoid using the
Controller in places near a radio, television set, or wireless
installing.
4.
These devices can cause radio disturbances which adversely
affect the performance of the Controller.
Mounting
Mounting to a Panel
1.
To mount the Controller so that it is waterproof, insert the
waterproof packing onto the Controller. Group mounting does not
allow waterproofing. The waterproof packing is not required if
waterproofing is not necessary.
The Panel Mounting Adapter is also included with the E5CN-U.
Waterproof packing is not included with the E5CN-U.
2.
Insert the E5CN/E5CN-U into the mounting hole in the panel.
3.
Push the adapter along the Controller body from the terminals up
to the panel, and fasten it temporarily.
4.
Tighten the two fixing screws on the adapter. Alternately tighten
the two screws a little at time to keep them balanced. Tighten
them to a torque of 0.29 to 0.39 N·m.
Attaching the Terminal Cover
Make sure that the “UP” letters on the E5CN are at the top and insert
the terminal cover into the holes at the top and bottom of the
Controller.
Removing the Controller from the Case
When carrying out maintenance on the Controller, the Controller can
be removed from the case with the terminal leads still attached. The
Controller can be removed from the case only with the E5CN. It
cannot be removed with the E5CN-U.
1.
Insert the tool into the slots (one on the top and one on the
bottom) and release the hooks.
2.
Insert the tool into the gap between the front panel and rear case
and pull out the front panel slightly. Hold both sides of the front
panel and draw out the Controller towards you. Do not apply
unnecessary force.
3.
Before inserting the Controller, confirm that the sealing rubber is
in place. Insert the Controller into the rear case until you hear a
click. Press on the hooks on the top and bottom of the rear case
to be sure that the hooks are securely locked in place.Be sure
that electronic parts do not come in contact with the case.
