17.Control outputs (for driving SSR) that are voltage outputs are not
isolated from the internal circuits. When using a grounded
thermocouple, do not connect any of the control output terminals
to ground. (Doing so may result in an unwanted circuit path,
causing error in the measured temperature.)
18.Use suitable tools when taking the Temperature Controller apart
for disposal. Sharp parts inside the Temperature Controller may
cause injury.
19.Do not use the Temperature Controller if the front sheet is peeling
off or torn.
20.Check the orientation of the connectors on the USB-Serial
Conversion Cable before connecting the Cable. Do not force a
connector if it does not connect smoothly. Using excessive force
may damage the connector.
21.Do not place heavy object on the USB-Serial Conversion Cable,
bend the cable past its natural bending radius, or pull on the cable
with undue force.
22.Do not connect or disconnect the USB-Serial Conversion Cable
while communications are in progress. Product faults or
malfunction may occur.
23.Make sure that the Conversion Cable's metal components are not
touching the external power terminals.
24.Do not touch the connectors on the USB-Serial Conversion Cable
with wet hands. Electrical shock may result.
25.The computer may operate incorrectly. Do not rapidly and
repeatedly insert and disconnect the USB connector on the USB-
Serial Conversion Cable.
26.The personal computer requires time to recognize the cable
connection after the USB connector is connected to the personal
computer. This delay does not indicate failure. Check the COM
port number before starting communications.
27.The USB-Serial Conversion Cable may malfunction. Do not
connect to a personal computer through a USB hub.
28.For the power supply voltage input, use a commercial power
supply with an AC input. Do not use the output from an inverter as
the power supply. Depending on the output characteristics of the
inverter, temperature increases in the product may cause smoke
or fire damage even if the product has a specified output frequency
of 50/60 Hz.
29.Make sure that the indicators on the Temperature Controller are
operating properly. Depending on the application conditions,
deterioration in the connectors and cable may be accelerated, and
normal communications may become impossible. Perform
periodic inspection and replacement.
30.When extending or connecting the thermocouple lead wire, be
sure to use compensating wires that match the thermocouple
types.
31.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.
32.The USB-Serial Conversion Cable may malfunction. Do not
extend the USB cable with an extension cable to connect to the
personal computer.
33.Noise may enter on the USB-Serial Conversion Cable, possibly
causing equipment malfunctions. Do not leave the USB-Serial
Conversion Cable connected constantly to the equipment.
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. Mount the product so that it is horizontally level.
2. 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: IP66
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.
4. When complying with EMC standards, the cable connecting the
sensor to the TC or Pt input must be 30 m or less. If the cable
length exceeds 30 m, compliance with EMC standards will not be
possible.
Mounting
Mounting to a Panel
For waterproof mounting, waterproof packing must be installed on the
Controller. Waterproofing is not possible when group mounting
several Controllers. Waterproof packing is not necessary when there
is no need for the waterproofing function.
1. Insert the E5CB into the mounting hole in the panel.
2. Push the adapter from the terminals up to the panel, and
temporarily fasten the E5CB.
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.
Precautions when Wiring
Separate input leads and power lines in order to prevent external
noise.
Use AWG24 (cross-sectional area: 0.205 mm
2
) to AWG14 (cross-
sectional area: 2.081 mm
2
) shielded twisted-pair cable.
Use crimp terminals when wiring the terminals.
Use the suitable wiring material and crimp tools for crimp terminals.
Tighten the terminal screws to a torque of between 0.74 and 0.90
N·m.
7.2 mm max.
7.2 mm max.
