Warren Controls AmurAct Actuator Linkage and Motor - Manual (Page 5)

1.
Good engineering practice
dictates that isolation valves must be installed in inlet and outlet
piping connected to the AmurAct control valve. A means should be provided to de-pressurize line media
trapped between them when they are shut. Pressure can cause the valve stem and any attached mechanism
to move with force, posing a threat to safety. Setup and an operational check of AmurAct actuation should be
completed before piping is pressurized.
2.
Potentially
hazardous voltages
may be present inside the AmurAct motor. Exercise caution when
removing its cover.
3.
When connecting high voltage wiring (115 or 230 volts AC) to the AmurAct motor, connect the
green
case grounding lead
, located inside the motor, to the ground wire of the power supply cable. This will
reduce the danger of electrical shock.
4.
Before removing a motor, the linkage
must be stabilized
by installing a small C-clamp onto the
Crank/Link as illustrated in procedures that follow. The C-clamp must remain in place until the motor clamp is
securely fastened to the linkage input shaft.
5.
Do not de-clutch the AmurAct motor
w/o first explicitly following all instructions on page 10.
If the goal is to only manually stoke the valve and not remove the motor, you must first follow steps 1 -5 of this
procedure and when finished perform the Auto-Calibration procedure on page 9. Failure to remove power AND
de-energize the Enerdrive system first, prior to de-clutching the motor will result in permanent motor damage
and
void the warranty
.
6.
Both parts of the
Safety Shield must be in place
before energizing AmurAct or pressurizing
piping.
7.
Exercise extreme caution when working on exposed AmurAct linkage parts. The geometric relationships of
linkage parts and their ranges of motion can
harm or sever fingers.
8.
Before adjusting the AmurAct valve stem connection, position the linkage so the plug is
not against
a valve seat.
The valve stem must never be turned while the plug is in contact with the valve seat, because
seating surfaces will be damaged
and tight valve closure will no longer be achieved! Detailed
procedures follow on pages 10-15.
9.
Contact the factory at (610) 317-0800
before attempting to reconfigure or reposition an
AmurAct actuator. Improperly rotating the linkage on the valve bonnet adversely affects linkage calibration,
can result in seat damage and/or operational failure; and
will void warranty coverage.
10.
Follow instructions to initiate the motor’s
Autostroke calibration cycle
each time AmurAct is
placed into service following any extended shutdown, adjustment or maintenance. Failure to do so can cause
inaccuracy of control and premature failure of the motor.
