E5C2

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

I 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.
