INSTRUCTION MANUAL

1. BEFORE USE ....
Thank you for choosing M-System. Before use, please check
contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact M-System’s Sales Office or representatives.
■PACKAGE INCLUDES:
Mini-Top ..............................................................................(1)
The Mini-Top is not provided with a yoke or other compo-
nents required for mounting it to a valve. They are to be
provided by the user.
■MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
2. POINTS OF CAUTION
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
24V DC: 24V rating ±10%, approx. 0.5A
■GENERAL PRECAUTIONS
• Remove the power supply to the actuator before wiring
to it.
■INSTALLATION
• Indoor, or outdoor where the MSPxC is NOT exposed to
direct sunlight
• Ambient temperature: -5 to +55°C (23 to 131°F)
• Operating humidity: 30 to 85% RH (non-condensing)
• Vibration: 0.5 G (4.9 m/s2) max.
• Install the MSPxC where you can reach for maintenance.
Observe at the minimum of 15 centimeters (6 inches)
above the cover.
■ELECTRICAL CONNECTION
• Separate the cables (power supply and communications)
from other cables to prevent surge or inductive interfer-
ence.
• Do not bind these cables together with mains supply ca-
bles or high-voltage cables. Do not install them in the
same duct.
■OUTDOOR USE
• When installing the MSPxC outdoor or where it is ex-
posed to rain or water drops, be sure to fasten the cable
connector tightly and leave a slack of the cable.
• Do not mount the MSPxC in such direction that the out-
put stem is at the top of the Mini-Top unit.
■O-RING, GASKET
• When replacing the actuator cover after adjustments,
check that the O-ring is securely placed in the groove.
• When replacing the communication box cover, check that
the gasket is in place.
■YOKE DESIGN
• When a foreign object is caught in the valve, a torque four
times greater than the maximum rating could be gener-
ated. Leave enough strength for mechanical components
such like the yoke and stem.
• If the MSPxC is used on a steam line in temperature
control, it is possible that the MSPxC temperature rises
higher than the ambient temperature due to transmis-
sion or radiation via the steam piping, even when the am-
bient temperature is within allowable range.
Use a longer yoke to increase heat dissipation and apply
insulating material.
■AND ....
• DO NOT loosen the screw fixing the potentiometer stem.
Loosening it could cause a malfunction.
• DO NOT step onto the actuator. DO NOT rest a heavy
object on or against it.

Note 1: Applying excessive torque on potentiometers and switches may destroy the stoppers of these adjustments. Turn them gen-
tly and stop immediately where the controls hit the stopper.
4. OUTPUT SPAN ADJUSTABILITY
The servo-control circuit compares and amplifies “Input as
Target” (position setpoint) signal and the feedback signal
from the potentiometer, and drives the motor to such direc-
tion to minimize difference of the two signals.

5. INSTALLATION
The following is a general procedure for mounting the
MSPxC to a valve with a yoke and coupling.
Be sure NOT TO CHANGE factory adjusted setting of the
MSPxC.
Remove power supply during the procedure unless other-
wise specified.
1) Supply power to the actuator and manually control the
actuator stem to the longest position.
2) Push in the valve stem at the lowest position.
3) Set the yoke to the actuator.
4) Push the valve stem into the actuator stem until there is
no gap between them.
If you need to seal the valve, leave a spring contraction
shown in Table 3 (for example, 0.5 mm for MSP4C-x3).
5) Fix the actuator stem and valve stem with a lock nut.
6) Supply power to the actuator again and raise (retract)
the actuator stem by several millimeters. Check that the
opening between the yoke and valve bonnet is closed. Fix
the yoke and valve.
7) Attach the position indicator if required.

7. ADJUSTMENT PROCEDURE
7. 1. MANUAL OPERATION
The MSPxC can be manually controlled regardless of the
communications status. Turn the SW5-1 ON to enable the
manual operation mode. The SW8 and SW7 are used for
control.

SW5 OFF ON

Control via com-
munications
Manual operation
2 Invalid 0% manual control command
3 Invalid 100% manual control command
4 Unused
Turning both SW5-2 and -3 is invalid. The actuator operation
stops.
SW8: The stem moved toward 0% position while pressing
this switch.
SW7: The stem moved toward 100% position while pressing
this switch.
7. 1. 1. GENERAL PROCEDURE
After installing the valve and actuator, go to adjustments in
order of Zero, Span, and the seal-spring.
7.1.2. ZERO & SPAN
1) Zero Adjustment: Turn the power supply on and set the
SW5-1 and -2 ON (OFF for the others on the SW5). This
turns the actuator into the manual operation mode and
automatically controls the stem toward the 0% position.
Once the stem reaches the position, adjust either the ac-
tuator with the Zero potentiometer or the mechanical po-
sition of the valve stem connection so that the actuator’s
extended position (valve’s retracted position) is adequate.
If extra sealing pressure by the seal-spring is required,
push in the actuator stem referring to Table 3.
2) Span Adjustment: Turn the power supply on and set the
SW5-1 and -3 ON (OFF for the others on the SW5). This
turns the actuator into the manual operation mode and
automatically controls the stem toward the 100% posi-
tion.
Once the stem reaches the position, adjust either the ac-
tuator with the Span potentiometer or the mechanical
position of the valve stem connection so that the actua-
tor’s retracted position (valve’s extended position) is ad-
equate.
For three-way valves, the sealing pressure can be adjust-
ed to be applied in the direction where the output stem
is fully retracted (not available for the MSP4C). Adjust-
ment procedure is the same for Zero.
3) With 0% input again, check that the Mini-Top is at the
fully extended position. If the position is shifted, go
through the above procedure again.
Note 1: There is only minimal effect of span adjustment to
zero point, thus the stem position shifts very little
at the extended side when the span potentiometer is
turned.
Note 2: With the stroke narrower, hunting (the motor repeats
changing direction) can happen more often. Adjust
Deadband in such cases.

7.2.4. BASIC OPERATING PROCEDURE
(1) Normal Operation
Once the communication is established, the actuator can
be operated only by setting ‘Enable Target Position Input’
(RY8) to ‘1’ and providing ‘Target Position Input’ value
(RWw0).
Target Position Input data is described by signed 16-bit
data, representing 0.01% by 1 LSB.
Set ‘Enable Target Position Input’ to ‘1.’
Set ‘Target Position Input.’
For example, set ‘5000’ in binary for 50% setpoint. Set ‘-50’
for -0.5%. Binary must be 2’s complement.
‘Position Output’ (RWr0) data is in the same format.
(2) Motor Deadlock Alarm
When the motor is overloaded or stuck with a foreign object,
the actuator sets ‘1’ to ‘Motor Deadlock Alarm’ (RX8) and
stops.
When ‘1’ is set to ‘Reset Motor Deadlock Alarm’ (RYA), the
actuator restarts.
Be sure to confirm that the Motor Deadlock Alarm is reset
to ‘0’ before returning Reset Motor Deadlock Alarm to ‘0.’
(3) Operation Report
The following data can be read out for maintenance purpos-
es: Motor Starting Counter, Motor Reversing Counter and
Accumulated Running Distance.
These data are stored in the nonvolatile memory every 10
minutes and are not deleted even when the power is re-
moved.
In order to reset these data to 0, set ‘1’ to the respective
reset commands (RYB to RYD).
Return the reset signals to ‘0’ after the data resetting has
been confirmed.
