Installation
Mechanical
The actuator should be mounted with the valve
stem in either horizontal position or pointing
upwards. Use a 4 mm Allen key (not supplied) to
fit the actuator to the valve body.
Allow for necessary clearance for maintenance
purposes.
The valve has position indication rings
which should be pushed together before
commissioning; after stroking they indicate the
ends of the stroke.
Electrical
Electrical connections can be accessed by
removing the cover. Two M16
×
1.5 cable entries
are provided. Both entries are provided with a
rubber grommet for use with flexible cable. Note
that in order to maintain the enclosure IP rating,
appropriate cable glands must be used.
Wiring
Note:
If switch SW6 is set to ON than use this wiring.

Automatic self stroking feature
When power is first applied, the actuator will
automatically adjust to the length of the valve
stroke. Subsequently, the self stroking feature
can be re-initialised by changing position of SW9.
Diagnostic LED
The red diagnostic LED is located on the pcb
under the cover. It provides indication of three
operational states:
• Actuator Healthy (Permanently ON),
• Self Stroking (Flashes once per second),
• Error (Flashes 3 times per second - seek
technical assistance).
