NOTE: The actuator may be mounted in any one of
four positions.
The following instructions explain how to mount
the actuator so that it is facing the outlet port.
To ensure the actuator is in the ‘zero’ position,
power on the actuator (a 24VDC regulated power
supply is required). Ensure the actuator is in
Temperature Controller mode - hold mode and
press down (-) on the actuator keypad to toggle
between Temperature and Positioner mode.
Once in Temperature mode, disconnect the
temperature probe from the actuator. The actuator
will move automatically to the ‘zero’ position and
the keypad display will show “E2”.
Set the Valve position to closed. Ensure the notch
on the spindle (Image 1) points towards the valve
“0” mark and the cold port (Image 2) which is the
fully closed position for the valve seats and the
default cold port (Image 2).
Place the graduated coupling (Image 3) on the
spindle & ensure the zero points to the outlet port
(Image 4).
If the actuator is to be mounted in one of the other
three positions, rotate the graduated coupling so
that the “ZERO” mark will line up with the notch in
the bracket (Image 8) of the actuator, when valve
is fully coupled to actuator.
DO THIS ALIGNMENT BEFORE PLACING THE
COUPLING ON THE SPINDLE.
Place the center coupling (Image 5) on the
graduated coupling (Image 6).
