Caution
We strongly recommend that all Neptronic® products be wired to a separate transformer and that transformer shall service only Neptronic® products. This precaution will
prevent interference with, and/or possible damage to incompatible equipment. When multiple actuators are wired on a single transformer, polarity must be observed. Long
wiring runs create voltage drop which may affect the actuator performance.

Mechanical Installation

1. Manually close the damper blades and position the actuator at 0º or 90º.
2. Slide the actuator onto the shaft.
3. Tighten the nuts on the “U” bolt to the shaft with an 8mm wrench to a torque of 60 in.lb. [6.7 Nm].
4. Slide the mounting bracket under the actuator. Ensure free movement of the slot at the base of the actuator. The bracket pin must be placed in the mid distance of the slot.
5. Fix the bracket to the ductwork with #8 self-tapping screws.

Wiring Diagrams

Analog

For 4 to 20mA control signal, connect supplied 500 Ohm resistor between pins 1 and 3.
For 2 to 10Vdc feedback signal, connect supplied 500 Ohm resistor between pins 1 and 5

PWM

3-wire/Digital 2 positions

4-wire/Digital 3 point floating

Note: In Digital Mode, the actuator is sensitive to induced electrical voltages from external sources. To prevent interference, install a 2.2k Ohm, 0.5 W resistor (included) between pins 1 and 3 and another between pins 1 and 4 of TB1 as shown above.
Note: In any of the above wiring configurations, connect a supplied 500 Ohm resistor between pins 1 and 5 for a 2-10Vdc feedback signal.

PC Board

DIP Switch Settings

NOTE*: To use DIP switch #3 in other modes (analog/digital), refer to Feedback Selection (CCW Direction) on page 4.

Stroke Adjustment – No control signal change

1. Apply power and, wait for at least 10 seconds.

2. Press and release the reset button to start the auto-stroke process.
   The LED should be illuminated.

   • First option:
     The actuator will then travel in both directions to find its limits and position itself according to the demand. The LED will extinguish, the process is complete.

   • Second option:
     When the desired end position is reached, press and release the reset button. The actuator goes to the start position. You can also press and release the reset button when it reaches the start position. Once this process is complete, the LED extinguishes.

Programming – Change of control signal

• Remove power and put all dip switches to “OFF” (Default).
• Apply power and, within 10 seconds, press and release the reset button. The LED should be blinking.
• Select the control signal with DIP switches:
  DIP Switch| Signal
  ---|---
  Move DS #1 to ON and then OFF| Digital, On/Off or 3 point floating
  Move DS #2 to ON and then OFF| PWM
  Move DS #3 to ON and then OFF| Analog (default)
• If PWM mode is selected; when programming is done
  • If DIP switch #3 is ON, PWM uses a 5-second pulse
  • If DIP switch #3 is OFF, PWM uses a 25-second pulse

Stroke adjustment
see the stroke adjustment section above.

Feedback selection (CCW direction)

To select the CCW direction, set DS #1 to ON, and if the actuator is in Analog or Digital mode, you can program the feedback signal direction.
If switch No3 is “OFF”:
The feedback control is automatically reverse to 4 to 20 mA for 90 to 0 degrees.

If switch No3 is “ON”:
The feedback control is to 20 to 4 mA for 90 to 0 degrees.

Zero and span calibration

This feature is applicable to analog control signal only.

1. Remove power and put all dip switches “OFF”. (factory preset).
2. Apply power and within 10 seconds press and hold the reset button until the LED flashes once. When the LED flashes, release the reset button, the LED remains illuminated and the zero and span calibration process starts. NOTE: Do not hold the reset button for too long as it may cancel the process.
3. Apply new minimum voltage. It can be any value between 0 to 7 Vdc, with an external 0 to 10 volt supply (ex: MEP).
4. Press and release the reset button to memorize the new minimum voltage. The LED flashes once and then remains illuminated.
5. Apply new maximum voltage. It can be any value between 3 to 10 Vdc; this value should be greater than the new minimum value.
6. Press and release the reset button to memorize the new maximum voltage. The LED flashes once and then turns off.

The Zero and span calibration process is complete.

Note: The voltage difference between the minimum voltage and high voltage settings must be at least 3V. If not, the actuator will ignore the values entered and use the previous values. For example, a minimum voltage of 5V and a maximum voltage of 7V represent a difference of 2V.
Note: To reset zero and span to 2 to 10 Vdc (factory value), re-select the analog control signal mode, see Programming.
