Precautions Definition of Safety Notices and Information The following notation is used in this manual to provide precautions required to ensure safe usage of the product. The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.
Page 6 ● Precautions CAUTION Do not touch any of the terminals or terminal blocks while power is being supplied. Doing so may occasionally result in minor injury due to electric shock. Do not touch the terminals, or electronic components or patterns on the PCB within 1 minute after turning OFF the power.
Page 7: Precautions For Safe Use
Take this into consideration when setting up the control system. (12) Allow the product to warm up for at least 30 minutes after the power is turned (13) Install surge absorbers or noise filters in devices near the product that generate noise (in particular, devices with an inductance component, such as motors, transformers, solenoids, and magnetic coils).
Page 8: Precautions For Correct Use
To prevent inductive noise, separate the wiring for the product's terminal block and connector from high-voltage, high-current power lines. Do not run the wiring parallel to or in the same cable as power lines. The influence of noise can also be reduced by using separate wiring ducts or shield lines.

Voltage inputs: 1 to 5 V, 0 to 5V, 0 to 10V ● Multi-point inputs • A 2-input type and a 4-point input type are available for the E5AR. A 2-point input type is available for the E5ER. • All multi-point inputs also support multi-input, eliminating the need for an externally connected converter.
Page 22: Outputs
Two-input types can use an external input for the set point. • SP ramp function This limits the amount of change of the set point based on the rate of change (SP ramp value). This function is useful for control applica- tions such as firing ceramics where sudden changes in temperature are not desirable.

Page 82 The upper-limit alarm and lower-limit alarm will be inverted. Therefore, set an alarm type and alarm values that invert the upper limit or lower limit of the display value. For example, if an absolute-value upper limit is set for the alarm type, operation will be as shown in the following figure.
Page 83: Selecting The Temperature Units
When the input type is set to temperature input (input from a thermocouple or a platinum resistance temperature input sensor), "°C" or "°F" can be selected for the temperature units. When using a multi-point input type, set the temperature units separately for each input (2 to 4) as appro- priate for the number of inputs.
