INITIAL STARTUP AND OPERATION
1.
After verifying that line isolation valves are shut, that wiring
connections and motor switches are properly positioned, and AmurAct
linkage safety covers are in place, apply power to the motor. Observe
that the LED light remains lit for 30-60 seconds. After the LED goes off,
indicating that the Enerdrive capacitors are sufficiently charged, press
and release the small RESET pushbutton beside the LED (see page
5 for location). The motor and valve will run through a slow-speed
calibration cycle, and then stop.
The LED will light when the RESET pushbutton is pressed and released
and remain lit during the calibration cycle. The LED will go out when
the calibration cycle is complete.
Initiate this AUTOSTROKE CALIBRATION CYCLE each time AmurAct is
placed into service following an intentional shutdown, adjustment or
maintenance. It apportions the input signal over the actual range of
valve stem movement for maximum accuracy of control, and provides
“soft stops” at both ends of travel to reduce gear impact and extend
motor life. Failure to do so can result in inaccuracy of control and
premature failure of the motor.
The 30-60 second pause occurs each time power is applied to the
motor, and allows the motor to recall its internal settings. No operator
action is needed to return to fully automatic operation following a
power outage. The Enerdrive fail-safe energy supply is fully restored
within one minute after power is restored.
Do not press the RESET pushbutton while the AUTOSTROKE
CALIBRATION CYCLE is in progress. IF the RESET pushbutton is pressed
while the AUTOSTROKE CALIBRATION CYCLE is in progress, the
calibration will not be correct. If the RESET pushbutton was pressed
during the AUTOSTROKE CALIBRATION CYCLE, allow the calibration
cycle to complete (LED goes out) then press and release the RESET
pushbutton to initiate a new AUTOSTROKE CALIBRATION CYCLE.
DonotpresstheRESETpushbuttonwithin10secondsofapplying power
to the actuator, unless you are resetting the actuator programming to
the factory default (See page 15). If the RESET pushbutton is pressed
within 10 seconds of applying power to the actuator, the LED will
either begin flashing approximately 1 flash/second or will light solid
and remain lit. If the LED is flashing, do not then change the position
of the dipswitches. If the LED is lit solid, do not then press the RESET
pushbutton or vary the control signal. These actions may result in the
actuator programming being changed. If the actuator progamming is
changed, the actuator may not respond correctly to the control signal.
If the LED was flashing approximately 1 flash/second and went out,
check the actuator response to a known properly calibrated control
signal. If the LED is flashing, wait for it to go out, approximately 60 to
65 seconds, before checking the actuator response. If the actuator does
not respond correctly to the control signal, and other troubleshooting
steps do not restore correct operation, you may need to reset the
actuator programming to the factory default (See page15).
If the RESET pushbutton was pressed within 10 seconds of applying
power to the actuator and the LED is lit solid and does not go out, turn
the power off and on again. Check the actuator response to a known
properly calibrated control signal. If the actuator does not respond
correctly to the control signal, and other troubleshooting steps do
not restore correct operation, you may need to reset the actuator
programming to the factory default (See page 15).
If the RESET pushbutton was pressed within 10 seconds of applying
power to the actuator and the LED was lit solid and went out, check
the actuator response to a known properly calibrated control signal. If
the actuator does not respond correctly to the control signal, and other
troubleshooting steps do not restore correct operation, you may need
to reset the actuator programming to the factory default (See page 15).

2.
Apply a known properly calibrated control signal and observe
that the control valve responds correctly by opening with an increasing
signal and closing with a decreasing signal (This is with the default
setting). Install the motor cover.
Preferred Calibration Accuracy: +2.5 A,
+1.5 mV (Typ).

3.
Fail-safe operation on loss of power can be tested when the
Enerdrive circut is fully charged by interrupting power to the motor.
Recall that there is up to a 60-second delay after power is restored.

4.
With power and control signal applied, slowly and carefully open
the isolation valves. Observe that the controller and control valve have
control of the process before leaving the area.

TO RE-ORIENT THE AMURACT ON THE VALVE
CONSULT FACTORY
If it is necessary to re-position AmurAct on the valve call the
factory at -- for procedural assistance.
FAILURE TO DO SO WILL VOID
THE WARRANTY COVERAGE.
