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 impedance
is 80 k ohm.)
3 A fie
ld-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 circui
ts.
5 For end position indication, interlock control,
fan startup, etc., MS4X-7XX3-502 models
incorporate two built-in auxiliary switches.
6 To reverse actuator rotation, use the
reversing switch.
7 Both actuators must be
set to operate in the
same direction.
