1 Provide overload protection and disconnect
as required.
2 For parallel 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.
