Foreword
4QD try to write a manual which is readable. Please
read the manual through before starting installation.
To help you, we have marked the more technical
sections ¶ so that you may ignore them.
This manual covers installation and wiring of 4QD's
Pro series controller in the usual applications. There
are finer points of installation which are outside the
scope of such a printed manual and you should refer
to our www site for more information.
Models
The Pro-120 is available either for 24v operation or
for 12v operation. Models can also be supplied for
36v and 48v
The voltage is marked on the relays. Make sure this
are correct as 24v relays will not operate from 12v
and 12v relays will soon burn out if used on 24v.
The standard model is suitable for permanent magnet
or shunt wound motors.
