Be sure to observe the following precautions to prevent malfunction
or adverse affects on the performance or functionality of the product.
Not doing so may occasionally result in faulty operation. Do not
handle the Digital Temperature Controller in ways that exceed the
ratings.
1. This product is specifically designed for indoor use only.
Do not use this product in the following places:
•Places directly subject to heat radiated from heating equipment.
•Places subject to splashing liquid or oil atmosphere.
•Places subject to direct sunlight.
•Places subject to dust or corrosive gas (in particular, sulfide gas
and ammonia gas).
•Places subject to intense temperature change.
•Places subject to icing and condensation.
•Places subject to vibration and large shocks.
2. Use and store the product within the rated ambient temperature
and humidity.
Gang-mounting two or more Digital Temperature Controllers, or
mounting Digital Temperature Controllers above each other may
cause heat to build up inside the Digital Temperature Controllers,
which will shorten their service life. In such a case, use forced
cooling by fans or other means of air ventilation to cool down the
Digital Temperature Controllers.
3. To allow heat to escape, do not block the area around the Digital
Temperature Controller.
Do not block the ventilation holes on the Digital Temperature
Controller.
4. Be sure to wire properly with correct signal name and polarity of
terminals.
5. Use the specified size of crimped terminals (M3, width of 5.8 mm
or less) to wire the E5CC, E5EC, E5AC, E5DC, or E5@C-T. To
connect bare wires to the terminal block of the E5CC, E5EC,
E5AC, E5DC, or E5@C-T, use copper braided or solid wires with
a gage of AWG24 to AWG18 (equal to a cross-sectional area of
0.205 to 0.823 mm2). (The stripping length is 6 to 8 mm.) Up to two
wires of the same size and type, or two crimped terminals can be
inserted into a single terminal.
Use the specified size of crimped terminals (M3.5, width of 7.2 mm
or less) to wire the E5CC-U. To connect bare wires to the terminal
block of the E5CC-U, use copper braided or solid wires with a
gage of AWG24 to AWG14 (equal to a cross-sectional area of
0.205 to 2.081 mm2). (The stripping length is 5 to 6 mm.) Up to two
wires of the same size and type, or two crimped terminals can be
inserted into a single terminal.
Use the specified size of crimped terminals (M3, width of 5.8 mm
or less) to wire the E5GC.*
To connect bare wires to the terminal block of the E5GC, use
copper braided or solid wires with a gauge of AWG24 to AWG18
(equal to a cross-sectional area of 0.205 to 0.823 mm2). (The
stripping length for Digital Temperature Controllers with screw
terminal blocks is 6 to 8 mm. The stripping length for Digital
Temperature Controllers with screwless clamp terminal blocks is 8
to 12 mm.)
Up to two wires of the same size and type, or two crimped
terminals can be inserted into a single terminal. When connecting
two wires into one terminal of a Digital Temperature Controller with
a screwless clamp terminal block, use ferrules with a diameter of
0.8 to 1.4 mm and an exposed conductor length of 8 to 12 mm that
two wires are crimped for a ferrule.*
* The Digital Temperature Controller with screwless clamp
terminals underwent UL testing with one braided wire connected.
6. Do not wire the terminals that are not used.
7. Use a commercial power supply for the power supply voltage input
to a Digital Temperature Controller with AC input specifications.
Do not use the output from an inverter as the power supply.
Depending on the output characteristics of the inverter,
temperature increases in the Digital Temperature Controller may
cause smoke or fire damage even if the inverter has a specified
output frequency of 50/60 Hz.
8. To avoid inductive noise, keep the wiring for the product’s terminal
block away from power cables carry high voltages or large
currents. Also, do not wire power lines together with or parallel to
product wiring. Using shielded cables and using separate conduits
or ducts is recommended.
Attach a surge suppressor or noise filter to peripheral devices that
generate noise (in particular, motors, transformers, solenoids,
magnetic coils, or other equipment that have an inductance
component).
When a noise filter is used at the power supply, first check the
voltage or current, and attach the noise filter as close as possible
to the product.
Allow as much space as possible between the product and
devices that generate powerful high frequencies (high-frequency
welders, high-frequency sewing machines, etc.) or surge.
9. Use this product within the rated load and power supply.
10.Make sure that the rated voltage is attained within two seconds of
turning ON the power using a switch or relay contact. If the voltage
is applied gradually, the power may not be reset or output
malfunctions may occur.
11.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.
12.When executing self-tuning with E5@C, turn ON power to the load
(e.g., heater) at the same time as or before supplying power to the
product. If power is turned ON to the product before turning ON
power to the load, self-tuning will not be performed properly and
optimum control will not be achieved.
13.A switch or circuit breaker must be provided close to the product.
The switch or circuit breaker must be within easy reach of the
operator, and must be marked as a disconnecting means for this
unit.
14.Use a soft and dry cloth to clean the product carefully. Do not use
organic solvent, such as paint thinner, benzine or alcohol to clean
the product.
15.Design the system (e.g., control panel) considering the 2 seconds
of delay that the product's output to be set after power ON.
16.The output may turn OFF when you move to the initial setting level.
Take this into consideration when performing control operations.
17.The number of non-volatile memory write operations is limited.
Therefore, use RAM write mode when frequently overwriting data
during communications or other operations.
18.Always touch a grounded piece of metal before touching the
Digital Temperature Controller to discharge static electricity from
your body.
19.Use suitable tools when taking the Digital Temperature Controller
apart for disposal. Sharp parts inside the Digital Temperature
Controller may cause injury.
20.For compliance with Lloyd’s standards, the E5CC, E5CC-U,
E5EC, and E5AC must be installed under the conditions that are
specified in Shipping Standards.
21.For the Digital Temperature Controller with two Setup Tool ports
(E5EC/E5AC/E5DC/E5GC), do not connect cables to both ports at
the same time. The Digital Temperature Controller may be
damaged or may malfunction.
22.Do not place heavy object on the Conversion Cable, bend the
cable past its natural bending radius, or pull on the cable with
undue force.
23.Do not disconnect the Communications Conversion Cable or the
USB-Serial Conversion Cable while communications are in
progress. Damage or malfunction may occur.
24.Do not touch the external power supply terminals or other metal
parts on the Digital Temperature Controller.
25.Refer to the E5@C Digital Temperature Controllers User’s Manual
(Cat. No. H174) for information on the communications distances
and cables for the E5@C.
For details on the E5@C-T, refer to the E5
@
C-T Digital
Temperature Controllers Programmable Type User’s Manual (Cat.
No. H185).
26.Do not bend the communications cables past their natural bending
radius. Do not pull on the communications cables.
27.Do not turn the power supply to the Digital Temperature Controller
ON or OFF while the USB-Serial Conversion Cable is connected.
The Digital Temperature Controller may malfunction.
28.Make sure that the indicators on the USB-Serial Conversion Cable
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.
29.Connectors may be damaged if they are inserted with excessive
force. When connecting a connector, always make sure that it is
oriented correctly. Do not force the connector if it does not connect
smoothly.
