Note: 1. At EN 61326-1 (Industrial electromagnetic environment (EN/IEC 61326-1 Table 2))

2.No reset function is incorporated by any E5C2 model with ON/OFF control.The reset function is used to correct offset for proportional control. If there is an offset below the set value, turn the reset adjustment clockwise.

3.A special Watertight Cover is used to achieve this degree of protection (IP66, NEMA4). Refer to Y92A-□□N.

 

■ Connections

Connecting the Input

1.Connect a thermocouple, the E52-THE□Thermistor (replaceable element) or a platinum resistance thermometer to terminals 1 (positive) and 2 (negative) on the E5C2 as shown in thefollowing illustration.

 

2.On the E52-□□1D, the lead wires are thermocouple element wires, making them difficult to solder because solder will not stick to them easily. Remove the crimp terminal and polish the ends before attempting to solder them.

 

Output

1.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.

2.We recommend using an external relay to extend the electrical life of internal relays whendriving a large capacity load. This is particularly important when the output relay is switched frequently (e.g., with proportional control).

 

Power Supply

1.If a single power supply is used for the E5C2 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.

2.The E5C2 operates at either 50 or 60 Hz.

Hard Protective Cover

A Hard Protective Cover (Y92A-48B) is available. It can be used in the following cases.

1.To protect the setting section, against dust and dirt

2.To prevent accidently changing settings by touching the front of the Controller.

3.To protect the Controller from water drips

Safety Precautions

Refer to Safety Precautions for All Temperature Controllers.

■ Correct Use

 

Mounting

Track Mounting (E5C2 with P2CF-08)

When mounting two or more E5C2 models with track-mounting sockets, leave a space of approximately 20 mm on both sides of the sockets where hooks are located.

 

Flush Mounting

Insert E5C2 into the square hole of the panel and insert an adapter from the back so that there will be no space between E5C2 and the panel. Then, secure the E5C2 with a screw.

 

The P3G-08 can be wired in the same way as the P2CF-08.

 

Dismounting

If flush mounted, loosen the screw of the adapter and disengage the hooks for dismounting.

 

Temperature Setting

Do not turn the temperature setting knob of the E5C2 with excessive force, otherwise the stopper of the knob may break.

Others

1.Do not remove the housing of the E5C2, otherwise the housing may break.

2.To clean the surface of the E5C2, 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 E5C2, otherwise the surface of the E5C2 will become damaged.
