Auto-stroke - re-calibration
In case the valve does not operate as expect-
ed, start the auto-stroke sequence to re-cali-
brate the closing point of the valve and to
make sure that the actuator is able to open the
valve fully. Press buttons
and
simultane-
ously for 6 seconds to start the auto-stroke.
Auto-stroke sequence
(display shows: “AUTO STROKE CYCLES”):
1.Valve is closed to determine closing point.
2.Valve is opened fully (independent of max.
flow chosen).
3. System returns to normal operation.
If actuator is not able to open valve fully, an
error will be displayed. An auto-stroke cannot
be cancelled.
Manual override
Manual override is used to temporarily set the
position of the valve regardless of the settings
and control signal for the actuator.
1. Turn off power to the actuator.
2. Remove actuator from valve as described.
3. Turn spindle to the relevant position (Clock-
wise to close valve, counter clockwise to
open valve). Be sure not to use more than
10 Nm torque. Please protect actuator from
water while not on valve.
4. Re-mount actuator on valve as described.
5. Turn on power to the actuator when normal
operation is needed.
General
Water must always be suitable treated, clean
and free of debris. It is recommended that a
strainer be installed prior to the valve body to
prevent damage or blockage due to debris.
Ensure that the valve is not in the fully closed
position when filling the system with water.
Further, it is recommended not to exceed
maximum differential pressure control range.
Warranty obligation
Failure to abide by all recommendations as
per this installation and operation instruction
will void warranty.
Do not remove cover from actuator. Opening
cover will void warranty.
When manually operating the valve (actuator
disconnected) do not use more than 10 Nm
torgue. Using more than 10 Nm torgue will
void warranty.
