Apply the new zero voltage
to terminal 3 (any value
between 0 and 7VDC).
Press and release the reset
button to memorize this value.
The LED should blink once as
confirmation.
Apply the new maximum voltage to terminal 3
(any value between 3 and 10VDC and at least
3VDC greater than the zero value).
Press and release the
reset button to memorize
this value. The indication
LED should blink once as
confirmation and then
cease to be illuminated.
The actuator will now operate with the new
zero value and span.
FAILURE: If the LED provides 3 sequences of
4 blinks, the zero and span programming was
unsuccessful. This may occur if the difference
between the zero and maximum voltages was
not equal or grater than 3VDC.
NOTE: The feedback signal will always be 4-
20mA or 2-10V and independent of the zero
and span adjustment.
Circuit board diode
over-torque warning signal
Continual blinking indicates that the actuator
torque output limit has been exceeded.
This may have been caused by debris in the
valve internals. Disconnect power and manu-
ally operate the valve to clear the debris.
Re-apply power. The actuator will automati-
cally recalibrate and reset. If the problem re-
occurs, remove the valve body and check for
debris.
Manual over-ride operation
Remove actuator cover and DISCONNECT
POWER. Failure to disconnect power may
cause damage to the actuator gears. Fit the
manual over-ride key (FlowCon No. ACC0001)
onto the valve spindle. Press the clutch. Rotate
the manual over-ride key to open or close the
valve as required.
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.
