10) Make sure that the 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.
11) When executing 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.
12) A switch or circuit breaker should be provided close to this unit. The switch or circuit breaker should be
within easy reach of the operator, and must be marked as a disconnecting means for this unit.
13) Always turn OFF the power supply before removing the body of the E5CN, E5AN, or E5EN from the case,
and never touch nor apply shock to the terminals or electronic components. When inserting the interior of
the product, do not allow the electronic components to touch the case.
Always turn OFF the power supply before removing the terminal block from the E5GN, and never touch
nor apply shock to the terminals or electronic components.
14) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
15) Design system (control panel, etc.) considering the 2 second of delay that the controller’s output to be set
after power ON.
16) The output may turn OFF when shifting to certain levels. Take this into consideration when performing
control.
17) The number of EEPROM 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) Do not remove the terminal block from the E5CN, E5AN, or E5EN. Doing so may result in failure or
malfunction.
20) Control outputs 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.)
21) When replacing the body of the E5CN, E5AN, or E5EN, check the condition of the terminals. If corroded
terminals are used, contact failure in the terminals may cause the temperature inside the E5CN, E5AN, or
E5EN to increase, possibly resulting in fire. If the terminals are corroded, replace the case as well.
When removing the terminal block of the E5GN to replace the Digital Temperature Controller, check the
condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the
temperature inside the Digital Temperature Controller to increase, possibly resulting in fire. If the terminals
are corroded, replace the terminal block as well.
22) Use suitable tools when taking the Digital Temperature Controller apart for disposal. Sharp parts inside
the Digital Temperature Controller may cause injury.
23) When applying Lloyd's standards, install the Digital Temperature Controller according to the requirements
given in Shipping Standards.
24) Do not use the Temperature Controller if the front sheet is peeling off or torn.
● Service Life
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.
The service life of electronic devices like Temperature Controllers is determined not only by the num-
ber of times the relay is switched but also by the service life of internal electronic components. Compo-
nent 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.
