M-system MSP5 - Wiring Connection

MSP4 / MSP5 / MSP6
P. 4 / 7EM-4854 Rev.8
INSTALLATION
The following is a general procedure for mounting the MSP
to a valve with a yoke and coupling.
Be sure NOT TO CHANGE factory adjusted setting of the
MSP.
Remove power supply during the procedure unless other-
wise specified.
1)
Supply
power to the MSP and apply 0% input (100% for
direct action). Turn the output stem fully clockwise (seen
from the cover).
2) Turn
the valve stem to fully closed position (fully clock-
wise).
3) Set the yoke to the MSP
.
4) Set the coupling to the valve stem and fit the MSP out-
put stem into the coupling. Then fix the yoke and valve
temporarily.
5) F
ix the coupling so that there is no eccentricity between
both stems.
6) F
ix the yoke and valve firmly after checking the eccen-
tricity of both stems again.
7) Attac
h the position indicator if required.
WIRING CONNECTION
Refer to the following diagram when wiring. If an optional terminal box is provided, remove its cover and connect lead-
wires.

Remark 1: The yellow wire must be left unconnected if the position output signal is not required. Cut the exposed section of
copper wire and insulate the tip of the wire.
Remark 2: The MSP6 is not provided with full-open/-closed signals.
