The reset adjuster of any E5C4 model with ON/OFF control is used to correct any error of the set temperature that is displayed so that the displayed temperature will coincide with the temperature that has been preset. The reset shaft of any E5C4 is used to reset the E5C4 model with proportional control. 2. The model number of the special watertight cover conforming to IP66, NEMA4 is Y92A-48N. 2 E5C4 E5C4 Nomenclature Temperature indicator Operation indicator Digital switch for temperature setting RESET shaft Negative Value Display (Example: –18°C) Overflow Display The following will be displayed if the sensor burnout detection circuit operates or the process value exceeds the temperature range that has been preset. (Except models with a set temperature range from 0°C to 399°C, 32°F to 799°F and 32°F to 199°F.) Indicates that the temperature is below 0°C. Note: 0°C to 999°C or 0°C to 99.9°C or 32°F to 999°F 0°C to 399°C The E5C4 does not have a parameter display any temperature below 0°C. Therefore, the accuracy of any temperature below 0° displayed by the E5C4 cannot be guaranteed. 32°F to 799°F 32°F to 199°F Operation Indicator Indicator Red Output Lit ON Not lit OFF 3 E5C4 E5C4 Dimensions Note: All units are in millimeters unless otherwise indicated.

Installation Connections Input Connect a thermocouple or platinum resistance thermometer to the E5C4 as shown in the following illustration. Voltage output (Terminal 6 is an NC terminal) Platinum resistance thermometer input Relay output Thermocouple input Supply voltage 100/110, 200/220, 110/120, 220/240 VAC, 50/60 Hz Output If the load circuit is a heating control system, be sure to connect the load to terminals 4 and 5. If the load circuit is a cooling control system, be sure to connect the load to terminals 4 and 6. If the heating control system is connected to terminals 4 and 6 or the cooling control system is connected to terminals 4 and 5, the temperature of the heating control system or cooling control system will be abnormal and a serious accident may result. If the E5C4 is in frequent operation, such as proportional operation, add an appropriate external relay to the E5C4 by considering the capacity of the load and the life of the relay. Do not ground the output of any E5C4 that has voltage output, otherwise the process temperature may not be accurate. Power Supply If a single power supply is used for the E5C4 and the load, the supply voltage of the power supply may vary greatly when the load is open or closed if the capacity of the power supply is not large enough. Make sure that the capacity of the power supply is large enough so that the supply voltage range will be always from 90% to 110% of the rated supply voltage. The E5C4 operates at either 50 or 60 Hz. 5 E5C4 E5C4 Precautions Mounting Dismounting Track Mounting (E5C4 with P2CF-08) When mounting two or more E5C4 models with track-mounting sockets, leave a space of approximately 20 mm on both sides of the sockets where hooks are located. If flush mounted, loosen the screw of the adapter and disengage the hooks for dismounting. Hook Duct P2CF-08 Panel Flush Mounting Insert E5C4 into the square hole of the panel and insert an adapter from the back so that there will be no space between E5C4 and the panel. Then, secure the E5C4 with a screw. Temperature Setting The leftmost digit of any E5C4 that has a set temperature range from 0°C to 399°C will increase by 1 within a range of 0 to 3 each time the push button for the leftmost digit is pressed. The leftmost digit indicating 3 will change to 0 when the push button is pressed. Others Tightening screw The P3G-08 can be wired in the same way as the P2CF-08. 6 Do not remove the housing of the E5C4, otherwise the housing may break. To clean the surface of the E5C4, use a soft cloth wet with neutral detergent or alcohol. Do not use any organic solvent, such as paint thinner or benzine, strong acid or strong alkali to clean the surface of the E5C4, otherwise the surface of the E5C4 will become damaged.
