1 Provide overload protection and disconnect
as required.
2 With four actuators wired to one 500 ohm
resistor, a +2% shift of the control signal
may be required. (Actuator input impe
dance
is 80 k ohm.)
3 A field-supplied 500 ohm resistor (AM-708)
is required between the gray and
yellow/black leads to convert the 4 to 20
mAdc control signal to 2 to 10 Vdc.
4 Only connect common to
negative (-) leg of
control circuits.
5 To reverse actuator control function
(direct/reverse action), use the reversing
switch.

If the controller uses a full wave power
supply and does not provide isolated outputs,
a separate transformer is needed.
