Section 1: Introduction
WARNING
Failure to follow instructions for proper electrical wiring, storage, setup, and maintenance
may cause serious injury, damage equipment, or void the warranty. Refer to Manual E796
for instructions on storage, electrical hook-up, and maintenance.
The Aquanaught Series 2000 actuator is intended for use in either marine water or waste
water applications where a portion or the entire valve actuator may be placed under water
for periods of time, typically during plant ooding conditions.
Internal controls and mechanical components are located in their sealed compartment.
State of the Art electronic controls are provided to insure safe and trouble-free operation at
a moment’s notice. The entire electrical package and motor wiring were tested and proven
to be continuously operational under 150 feet of sea water head immersion even without
their enclosure protection for 7 days though it acted as second line of defense in case of
leakage due to human error. An optional water sensor can be added as prognostic and
diagnostic indicator of any water ingress to the electrical enclosure if it might occur.

Features
Section 2: Features
The actuator features several assemblies as listed below – refer to Figure 1.
• LDM – Local Display Module: Contains actuator micro-processor which monitor
the system health and indicate the control feedback.
• SCM – Separate Control Module: Houses electrical controls to include optional
inverse time Circuit Breaker, Overload Relay and Spacer Heater.
• MCB – Motor Conduit Box: Cover threaded with o-ring seal to prevent water entry.
Motor wire splicing with hermetically sealed connectors for ease of motor removal
and installation.
• AEE – Actuator Electric Enclosure: Houses both Position & Torque switches
with hermetically sealed electrical contacts for positive operation. Includes
encapsulated sealed non-contacting absolute position encoder (hall effect sensor)
for valve position feedback. Each component has its own hermetically sealed
connectors for ease of maintenance and installation.
• 2” AWWA Nut with Torque Limiter: Optional vertical drive system allows operator
to hand drive the valve actuator in case of electrical failure. The adjustable torque
limiter will be included to prevent from over-torque.

Local Display Module
Section 3: Local Display Module
Contains micro-processor controller. This is the main controller used to setup and operate
the actuator.
This module displays operating parameters, valve position, and alarms, and provides for
conguration of the actuator controls.
To use the Local Control and Selector Knobs refer to the following table.
Table 1.
Selector Knob (right) Rotate Function Results
OFF (Stop) [return position] Stop Movement Prevents motor operation.
REMOTE (Auto) Clockwise Remote Control Allows control from remote
location.
LOCAL (Hand) Counter - clockwise Hand Operation
Allows control from the local
control knob or the control
knob of the RDM, if connected.
(while selector is in LOCAL [hand] mode)
Control Knob (left) Rotate Function Results
Spring return Neutral position No operation
Releases a local command
when Local control mode is
congured for maintainance
CLOSE (UP) Clockwise Local command to
close valve
Commands valve to move in
the close direction
OPEN (DOWN) Counter - clockwise Local command to
open valve
Commands valve to move in
the open direction
3.0.1 Operation
Place the “Selector Knob” in the desired operating position.
LOCAL – used for hands on operation of the actuator by manipulation of the Control Knob.
REMOTE – used within the context of plant operation, i.e. Remote Control Panel, PLC, DCS,
etc. See wiring diagram for typical user wiring for remote control.
3.0.2 Local Operation
Place the “Selector Knob” in the “Local” position. If a remote display is connected,
the remote selector switch must not be in the “Off” position. Verify that the selector “L”
amber light is on. The actuator may now be operated with the local Control Knob.
To Open the valve, rotate the control knob in the counterclockwise direction to the Open
direction.
To Close the valve, rotate the control knob in the clockwise direction to the Close direction.
To Stop the valve, momentarily rotate the control knob in the opposite direction of travel
or move the Selector knob to the OFF (Stop) position.

3.0.3 Operational Display
Valve position indication for Close / Mid Stroke / Open position is through use of long
lasting LED’s. Percentage of Open or Close is shown on the digital readout during normal
operation & displayed on the readout as either “OP” when full Open or “CL” when full Close.
CLOSE LED ashes while the valve is moving in the close direction.
It is steady on while the valve is fully closed.
OPEN LED ashes while the valve is moving in the open direction.
It is steady on while the valve is fully open.
MID (Yellow) LED is steady on while the valve is stopped in mid-travel.
This yellow LED ashes when an alarm is present.
OVER TORQUE alarm conditions are indicated for both Open and Close direction of
operation. When a torque alarm occurs in mid-travel, the over torque LED will ash for the
direction of travel. When the valve is torque seated, the CL over torque LED will remain
steady on.
Selector switch LEDs are also made available for operational use in the bottom right corner.
The selector LEDs are important when using a Remote Display Module (RDM) because
these LEDs indicate the combined logic of the two selector switches, i.e. the selected mode
of operation of the actuator.

NOTE:
Color of the Close and OPEN LEDs may be reversed in setup mode.

3.0.4 Alarms Display
When an alarm occurs, it is automatically displayed by the two character LED display.
The yellow MID LED will ash while any alarm is present. The display will alternate between
the current position and the active alarm(s). If more than one alarm is active, the display will
cycle through a sequence of valve Position, newest alarm, Position, next oldest alarm and
so on until all active alarms are displayed. The cycle is continuously repeated until all alarms
are cleared. Each alarm is recorded in an Alarm History. The alarm history may be viewed by
entering setup mode (see next section).
All possible alarms that may be displayed are listed on the name plate of the display Local
Display Module (LDM). Following are denitions of the listed alarms.
CE Communication Error Lost communication with the Remote Display
Module (RDM) when congured.
SA Stall Alarm Actuator failed to move within 8 seconds after
commanded by either local or remote controls.
LE Local ESD Hardwired Local Emergency Shut Down is active.
PH Phase Alarm Lost of one phase when congured for 3-Phase.
CF Control Failed Failure of the motor starter when sensed feedback
does not match command.
AF Actuator Failed A fault is detected by hardware electronics fault
monitor. This is a non-recoverable condition that
requires actuator service.
OL Motor Overload Motor thermals or motor overload relay has
tripped.
LP Lost Position Lost feedback from the Hall-effect Position Sensor
(HPS) located in the AEE.
LC Lost Control Voltage Loss of power to the motor control circuits.
The control voltage supply has an automatic
resetting fuse.
HA H2O Sensor Alarm Water ingress into the electrical enclosure.
NOTE:
Over torque alarms are displayed by dedicated LEDs. See Operational Display section above.
