The PWM input signal configuration responds to a timed pulsed signal (consisting of a leading and trailing edge) with a period between the minimum pulse width
setting (0.1 or 0.59 sec depending upon the setting of switch 3) and the maximum pulse width setting (25.5 or 2.93 sec depending upon the setting of switch 3). The
actuator responds to the width of the pulse relative to the pulse width span selected by switch 3. For example, if switch 3 is OFF, the actuator proportionally responds
to pulses between 0.59 sec and 2.93. sec. Thus, if the actuator receives a pulse consisting of a leading and trailing edge for 1.37 sec, the actuator positions the valve
stem to 33.3% because 1.37 sec is 33.3% between 0.59 and 2.93 sec. When setup for the PWM mode, the actuator responds to the last pulse signal received even if
the actuator is moving when the pulse is received.

DIP Switch Operation
The MGF350V-24FP, MG350V-24M, and MGF350V-24MP actuators have a DIP switch block located under the cover to the left of
the wiring terminal. The MG350V series actuators are shipped with all their DIP switches in the OFF (down) position. If any DIP
switch is changed while the actuator is unpowered, it recognizes the DIP switch change the next time the actuator is powered,
initiates its calibration sequence, and then controls according to the latest DIP switch setting. If a DIP switch is changed while the
actuator is powered, it recognizes the DIP switch change, initiates its calibration sequence after 15 seconds, and then controls according to the latest DIP switch setting.
Auto-Calibration Operation
MGF350V-24FP, MG350V-24M (no position output signal), MGF350V-24MP actuators with DIP switches have an auto-calibration
program. Auto-calibration occurs the first time the actuator is mounted to the valve and powered, as well as any time a DIP switch
is changed. During the auto-calibration procedure, the actuator strokes the valve full stem down (actuator linkage extended) to
full stem up (actuator linkage retracted) in order to identify the two end of travel points. The input signal is then spanned to match
this travel distance. The valve calibration data is stored in permanent memory, and the actuator resumes normal operation from its
input signal.

Installation Instruction
During the calibration process, the actuator’s LED provides indication of calibration status, and the actuator’s position output signal indicates that it is in calibration mode. See the LED Operation section for more details. If the actuator is unable to calibrate, it
provides an LED status error. After the actuator has calibrated and is powered after a power failure, the actuator strokes the valve
full stem up (actuator linkage retracted), and then responds to its control signal.
The auto-calibration process can also be manually initiated by changing any DIP switch. If a DIP switch is changed while the actuator is unpowered, it recognizes the DIP switch change the next time the actuator is powered, initiates its calibration sequence,
and then controls according to the latest DIP switch setting. If a DIP switch is changed while the actuator is powered it recognizes
the DIP switch change, initiates its calibration sequence after 15 seconds, and then controls according to the latest DIP switch
setting.
Power Up Operation
The MGF350V-24FP, MG350V-24M, and MGF350V-24MP actuators remain in their last commanded position with no power applied. When power is applied, the actuator strokes the valve stem full up (actuator linkage retracted). While the actuator is retracting to its retracted position, its position feedback output signal (for MGF350V-24FP and MG350V-MP models only) remains at 0.4
Vdc (if Switch 2 is OFF) or 0 Vdc (if Switch 2 is ON). After the valve stem reaches its full up position (actuator linkage retracted),
the actuator then positions the valve in accordance to its control input signal and the position output signal indicates the valve
stem position.
The MG350V-24F actuators remains in their last commanded position with no power applied. When power is applied, the actuator
operates in accordance to its input control signals to retract or extend the valve stem.
Positioning and Sensitivity
The MG350 series actuators include a built-in microprocessor that provides accurate motor control and overload protection at all
of its stroke positions. The microprocessor constantly monitors the rotation of the stepper motor and stops the pulses to the motor
when it senses a stall condition. The proportional MG350V-24M and MGF350V-24MP actuators include a 1% positioning sensitivity
and “a change of direction” algorithm with a wider 2.5% sensitivity to accurately follow the proportional control signal while not
responding unnecessarily to electric noise and control input instability. The floating MGF350V-24FP accumulates repeated small
drive open and drive closed commands and positions the valve when the commands are consistently in the same direction to
provide accuracy while not responding unnecessarily to electric noise and control input instability.
Manual Override Operation
Use the manual override to manually position the actuator
when it is not powered. The actuator stays in the selected position until powered. After power is applied, the actuator strokes
the valve full stem up (actuator linkage retracted), then positions the valve according to its control input signal. The manual
override accepts a 3 mm allen wrench. Press firmly (depressing the wrench downward approximately 1/8” (3 mm) into the
actuator) and continue to hold the wrench in the depressed
position, then turn the wrench CCW to extend the actuator
spindle, lowering the valve stem, or CW to retract the actuator
spindle, raising the valve stem. It takes approximately 3 …
3-1/2 manual override wrench turns to fully stroke the valve
stem (each manual override turn moves the valve stem about
5/32” (4 mm).
Note: If the allen wrench is not seated properly or if the user
does not press firmly downward, it will not engage, and the
wrench may spin inside the nut.
