4-8 Connecting control outputs (outputs 1, 2)

WARNING

Before wiring, or removing/mounting the DCP301, be sure to turn the power OFF. Failure to do so might cause electric shock.

•The life of internal relays is limited.

Avoid setting the PID constant in such a way that results in excessive repeated ON/OFF switching.

•When using a 100/200Vac motor, pay attention to rush current and the contact rating. If necessary, provide an external auxiliary relay.

•Separate the wiring for motor terminals (11) (12) (13) and feedback resistor terminals (14) (15) (16).

(Do not wire the leads in the same duct or use 6-core cable. Doing so might result in faulty controller operation caused by electrical noise when the motor is started up.)

•When controlling without motor feedback with variable parameter M .-Cset to “2”, terminals (14) (15) (16) need not be connected.
