INSTRUCTIONS
Valve actuator for 0...10V control signal
AQM2000A-1R is a valve actuator for 0...10 V DC control signal. It has
an automatic calibration function for calibration of starting point and
stroke. This allows simple adaptation to various valves.
AQM2000A-1R is intended for valves from the Osby NMTV/NMTR- and
N2SA/N2SB-series.
Mounting position
The valve should be mounted so that the actuator is positioned with the
drive rod within 90° from the vertical with the motor housing at the top.
Ensure that there is adequate space above the valve stem to allow
mounting of the actuator.
Mounting of the actuator on the valve
If the valve is not installed, grip it in a vice for stability.
Push the valve stem fully down and thread the supplied jam nut onto
the stem such that the nut is slightly above the valve bonnet.
Fully extend the the valve stem.
Insert the stem into the actuator adaptor yoke and thread the drive rod
nut onto the valve stem until snug. Loosen 1/2 turn again so the
actuator may be screwed onto the valve without damaging the drive rod.
Should the drive rod need to be extended, this can be done by turning
the shaft marked "P" counter-clockwise.
Gently push the actuator down to meet the thread on the valve bonnet.
Screw the actuator onto the valve as far as it will go and lock it by
tightening the locking nut against the yoke.
Turn the drive rod jam nut until tight against the drive rod nut. Lock the
two nuts using two spanners.
Wiring
Connect supply and control signal. If the actuator and the controller
share a common transformer it is important to ensure that both units
use the same transformer pole as neutral.
Terminal 1 = Neutral.
Terminal 2 = 24 VAC supply voltage.
Terminal 3 = 0...10V DC control signal.
Terminal 5 = 4...20mA feedback.
Zero and span adjustment
On commissioning it is necessary to let the actuator run through the
automatic calibration function in order to adapt it to the valve's stroke
and closing point.
After applying power wait at least 10 seconds (until the LED is
extinguished). Depress and release the button SW1. This initiates the
calibration feature. Over the next few minutes the actuator will self
stroke fully up and down during which time the LED will remain lit. Once
the LED is extinguished the calibration is completed. The actuator is
now programmed to give a full 2...10V resolution for the stroke of the
valve.
INSTRUCTIONS
Running direction
Running direction is set using the the DIPswitch #1.
Other control signals
The AQM2000A-1R actuator can be reprogrammed to suit other control
signals within the range 2...10 V DC, for example
3...7 V DC or 6...10 V DC. This enables sequencing several actuators
from one control signal.
Reprogramming of control input:
1. If the actuator is already under power, disconnect the power and
wait for at least 10 seconds.
2. Apply power again and within the first 10 seconds press and hold
the button SW1 until the LED blinks once. This initiates the
calibration sequence.
3. Release SW1. The LED is now constantly illuminated.
4. Apply a control signal corresponding to the desired lower value. It
must be in the range 2...7 V DC. Briefly depress SW1. Wait until the
LED blinks once indicating acceptance of the value.
5. Increase the control signal to the desired upper voltage. This must
be at least 3 V higher than the lower value. Briefly depress SW1.
After a few seconds the LED will be extinguished indicating that the
value has been accepted and the actuator has resumed normal
operation.
3-point floating control
AQM2000A-R1 can be reprogrammed to 3-point floating control.
1. Wire the actuator
Terminal 1 = Neutral
Terminal 2 = 24 V AC (28...32 V DC) always connected
Terminal 3 = 24 V AC (28...32 V DC) Drive up on activation
Terminal 4 = 24 V AC (28...32 V DC) Drive down on activation
Terminal 5 = 4...20 mA Feedback signal
2. Set all DIP-switches to Off position
3. Apply voltage and within 10 seconds, press and release SW1. The
LED should start flashing.
4. Move DIP-switch #1 to On and then back to Off
The unit is now programmed for 3-point control.
It can be reprogrammed back to 0...10 V control by running through
points 2...4 but using switch 3 instead of switch 1.
In 3-point control mode the unit is sensitive to induced electrical
voltages from other sources. to prevent such interference, wire one of
the supplied 2.2 kOhm resistors between terminals 1 and 3 and the
second 2.2 kOhm resistor between terminals 1 and 4.
