C.5.2 Remote Manual Control
The actuator may be equipped to connect to a remotely located
manual station. Operation of this option requires a two position
switch (Auto/Manual) and two (normally open) push-button switches,
extend (CCW) and retract (CW). Power for the switches is supplied
by the Control Enclosure. Actual position is available through the
position transmitter.
The user may provide the manual station, or two types of NEMA 4
manual stations are available from REXA:
BB: Material: Fiberglass
one Remote/Auto switch, two position
one Open switch, Momentary, Push to operate
one Close switch, Momentary, Push to operate
Connection: Terminal strip
Dx: Material: Fiberglass
one Remote/Auto switch, two position
one Open switch, Momentary, Push to operate
one Close switch, Momentary, Push to operate
Position indicator, 0-100%, includes Active Position
Transmitter within the Control Enclosure
Connection: Terminal strip
On actuators equipped with an alarm relay (see section C.4), the
relay will indicate that the actuator is not available to follow the
control signal. If the bumpless transfer is set to ON ([CtL:bt]=ON),
then the actuator’s position and control signal must be within 5%
before automatic control is resumed (see section 6.3.3).
C.6 Advanced Control Options
Four additional features are available within the SEtUP mode to
augment actuator operations. They are 0.05% deadband, minimum
control point, water hammer (two speed), and flow characterization.
On certain applications, these features can improve performance
and increase valve life.
