INITIAL STARTUP AND OPERATION
1.
After verifying that line isolation valves are shut, that wiring
connections and motor switches are properly positioned, and Amu-
rAct linkage safety covers are in place, apply power to the motor.
Observe
that the led light remains lit for 30 seconds. After the led goes off, in-
dicating that the Enerdrive capacitors are sufficiently charged, press
and release the small RESET pushbutton beside the led (see page
6 for location). The motor and valve will run through a slow-speed
calibration cycle, and then stop.
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 pro-
vides “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-second pause occurs each time power is applied to the mo-
tor, 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.
2.
Apply a control signal and observe that the control valve re-
sponds correctly by opening with an increasing signal and closing
with a decreasing signal (This is with the default setting). Install the
motor cover.
3.
Fail-safe operation can be tested at any time by interrupting
power to the motor. Recall that there is up to a 30-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.
