Precautions for Correct Use
Service Life
1. Use the product within the following temperature and humidity
ranges:
Temperature: 10 to 55C (with no icing or condensation)
Humidity: 25% to 85%
If the product is installed inside a control board, the ambient
temperature must be kept to under 55C, including the
temperature around the product.
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 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
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: IP50
Rear case: IP20, Terminal section: 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 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.)
3. Avoid using the 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.
Mounting
Mounting to a Panel
E5CSL/E5CWL
1. Insert the E5CSL/E5CWL into the mounting hole in the panel.
2. Push the adapter from the terminals up to the panel, and
temporarily fasten the E5CSL/E5CWL.
3. 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.
E5EWL
1. Insert the E5EWL into the mounting hole in the panel.
2. Attach the adapter provided with the product to the mounting
grooves on the top and bottom surfaces of the rear case.
3. Push until adapter reaches the panel and is fixed in place.
Mounting the Terminal Cover
Make sure that the rib on the E53-COV19 Terminal Cover to lower
side, and then attach the this cover to E5CSL/E5CWL/E5EWL.
Precautions when Wiring
Separate input leads and power lines in order to prevent external
noise.
Use specified size (M3.5, width 7.2 mm or less) crimped terminals
for wiring. To connect bare wires to the terminal block, use copper
braided or solid wires with a rated temperature of over 70C and a
gauge of AWG24 to AWG14 (equal to a cross-sectional area of
0.205 to 2.081 mm
2
). (The stripping length is 5 to 6 mm.) Up to two
wires of same size and type, or two crimped terminals can be
inserted into a single terminal.
Use crimp terminals when wiring the terminals.
Use the suitable wiring material and crimp tools for crimp terminals.
Tighten the terminal screws to between 0.74 and 0.90 N·Em.
Use the following types of crimp terminals for M3.5 screws.
