Accessories (Order Separately)

Protective Cover Y92A-48

The protective cover protects the front panel, particularly the setting

section, against dust, dirt, and water drip. It also prevents the set val-

ues from being altered due to accidental contact with the setting

keys.

Installation

■Connections

Input

Connect a thermocouple, the E52-THE@ Thermistor or platinum

resistance thermometer to the E5C2 as shown in the following illus-

tration.

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 sys-

tem, 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 con-

trol 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 E5C2 is in frequent operation, such as proportional operation,

add an appropriate external relay to the E5C2 by considering the

capacity of the load and the life of the relay.

Power Supply

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.

The E5C2 operates at either 50 or 60 Hz.

Precautions

Mounting

Track Mounting (E5C2 with P2CF-08)

When mounting two or more E5C2 models with track-mounting sock-

ets, leave a space of approximately 20 mm on both sides of the sock-

ets 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

Do not remove the housing of the E5C2, otherwise the housing may

break.

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.
