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 positioned 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 a 10mm wrench to a torque of 150 in.lb. [17 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.

Special consideration for Digital control
In this mode, the actuator is sensitive to induced electrical voltages from external sources. To prevent such interference, if the signal on pins 4 and 3 on TB1 are from an external 24 Vac source, install a resistor 2.2kohm, 0.5W between pins 4 and 1 and another of 2.2kohms, 0.5W between pins 3 and 1 of TB1. These resistors are included.

Input Signal and Feedback setup

| Input Signal| Feedback
---|---|---
Analog Mode| Input Signal is set with Dipswitch # 3
DS1-3 at OFF = 2 – 10Vdc (default setting) DS1-3 at ON = 4 – 20mA| Feedback is set with Dipswitch #4 DS1-4 at OFF = 4 – 20mA (default setting) DS1-4 at ON = 2 – 10Vdc
Digital & PWM
Mode| No Input Signal Setting
! DS1-3 MUST be at OFF

PC Board

Stroke adjustment – No control signal change

1. Apply power and, WAIT FOR LED TO BE OFF (around 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 limit and position itself according to the demand. The LED will extinguish, the process is complete.

   • Second option:
     When the desired start position is reached, press and release the reset button. The actuator will now go the end position. (you can also press and release the reset button when It’s reaches the end position) The LED will extinguish, the process is complete.

Programming – Change of control signal& PWM pulse setting

1. Remove power and put all dip switches “OFF”. (factory preset).
2. Apply power and, within 10 seconds, press and release the reset button. The LED should be blinking.
3. Select the control signal with dip switches:
   | Digital or Analog Modes| PWM Mode
   ---|---|---
   Move switch No1 “ON” and then “OFF”.| Digital (On/Off or 3 point floating)| 5 sec. pulse (factory preset)
   Move switch No2 “ON” and then “OFF”.| Analog (Default)| 25 sec. pulse
4. Stroke adjustment
   see the stroke adjustment section above.

Enabling or disabling PWM mode

1. Remove power supply to actuator
2. Install jumper between pin 3 & 4 of J3
3. Select the desired action using the dipswitches (DS1):
   DS1-1| DS1-2| Action
   ---|---|---
   OFF| ON| Enable PWM Mode
   ON| OFF| Disable PWM Mode
4. Re-apply power supply to actuator
5. Wait 5 seconds
6. Remove power supply to actuator
7. Remove jumper between pin 3 & 4 of J3, re-install it between pin 4 & 5.
8. Re-apply power supply to actuator
   PWM is factory preset at 5 sec. pulse, refer to programming section above to change pulse setting.

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 blinks once. The Zero and span calibration process then
3. Release the reset button. The LED is now constantly
4. Apply new minimum It can be any value between 0 to 7 Vdc, with an external 0 to 10 volt supply (ex: MEP).
5. Press and release the reset button to memorize the new minimum voltage. The LED
6. Apply new maximum It can be any value between 3 to 10 Vdc, this value should be greater than the new minimum value.
7. Press and release the reset button to memorize the new maximum voltage. The LED The Zero and span calibration process is complete.

Note: To reset zero and span to 2 to 10 Vdc (factory value). You just have to re-select the analog control signal mode, see Programming.
