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 E5C4 is in frequent operation, such as proportional operation,

add an appropriate external relay to the E5C4 by considering the ca-

pacity of the load and the life of the relay.

Do not ground the output of any E5C4 that has voltage output, other-

wise 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.
