1 Provide overload protection and

2 For unison operation in 4 to 20 mA
applications, actuators may be
wired in series and mounted on
separate shafts. Also, up to four
actuators, mounted on separate
shafts may be wired in parallel.
With four actuators wired to one
500 ohm resistor, a +2% shift of the
control signal may be required.
Power consumption and input
impedance limits must be
observed. Actuator input
impedance is 80 kohm.
3 For end position indication, interlock
control, fan startup, etc., MS40-
7043-501 model incorporates one
built-in auxiliary switch.
4 To reverse actuator rotation, use
the reversing switch.
5 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.
6 Only connect common to negative
(-) leg of control circuits.
