FAQ

• Q: Is the SM000FNC Actuator compatible with other equipment?
• A: It is recommended to wire the actuator to a separate grounded transformer to prevent interference and possible damage to incompatible equipment.
• Q: What control signals can the actuator accept?
• A: The actuator can accept a control signal of 2-10Vdc or 4-20mA, selectable via DIP switches.
• Q: How can I activate the auto-stroke feature?
• A: To activate the auto-stroke feature, press and release the push button while the unit is in normal operating mode. The actuator will travel in both directions to find its limit and position itself according to the demand.

Dimensions

• A = 1.50” (38mm)
• B = 3.64” (93mm)
• C = 6.60”(168mm)
• D = 3.02” (77mm)

Mechanical Installation

1. Manually close the damper blades and position the actuator to 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.- lbs [6.7 Nm].

4. Slide the mounting bracket under the actuator.
   Ensure free movement of the slot at the base of the actuator.
   Place the bracket pin at mid-distance of the slot.

5. Affix the bracket to the ductwork with #8 self-tapping screws.

Wiring
We strongly recommend that all products be wired to a separate grounded transformer and that transformer shall service only these products. This precaution will prevent interference with, and/or possible damage to incompatible equipment.

Error or Configuration mode

Normal Operation

The status LED will indicate the selected control mode:

Auto-Stroke Adjustment

• As a default, the auto-stroke feature is disabled and can only be activated manually.
• To initiate an auto-stroke process, press and release the push button while the unit is in the normal operating mode (status LED flashes slowly 1Hz). The status (green) LED will remain lit.
• The actuator travels in both directions to find its limit and position itself according to the demand. The LEDs will extinguish when the process is complete. The status LED will then continue flashing slowly (1Hz).

Configuration Instructions

• Set all the dip switches to OFF, then press and hold the push button (PB1) for 3 seconds. The red alarm LED will blink with one pulse, meaning that the first menu (Control State) is now accessible.
• Select the desired control mode by setting the associated dip switch to ON. In the absence of a selection, the control state menu shall remain unchanged.

Menu| Number of Alarm LED Pulses| Dip Switch 1| Dip Switch 2| Dip Switch 3| Dip Switch 4
---|---|---|---|---|---
Control State| 1| Analog (Modulat- ing)*| Digital (On/Off or

floating)

| PWM (5 sec)| PWM (25 sec)
Zero Span| 2| 2-10Vdc*| 0-10Vdc| Minimum value| Maximum value

• To navigate through the configuration menus, press and release the push button (PB1).
  • Press again to access the second menu (Zero Span). There will be 2 pulses on the alarm LED.
  • Press again to go back to the first menu (Control State).
• To change the span range to something other than 2-10Vdc or 0-10Vdc, access the Zero Span menu and do the following:
  • Input the desired minimum voltage to the white wire, then set dip switch 3 to ON.
  • Input the desired maximum voltage to the white wire, then set dip switch 4 to ON.
  • The maximum voltage must be at least 3V greater than the minimum voltage, and they must both lie within 0 to 10V.
• To leave the configuration menu and save any changes, press and hold the push button (PB1) for 3 seconds.
• To undo changes and reset the settings back to the factory default, press and hold the push button (PB1) for about 15 seconds.

Solution

---|---|---|---

1

| ****

Power fail

| The actuator is not receiving any power and is shutting off.| ****

Ensure the actuator is properly connected the power supply source.

2

| ****

Auto-stroke

| The actuator auto-stroke is not at a minimum of 30°.| Press the push button (PB1) and ensure that the span is greater than 30°.

3

| ****

Over-torque

| The actuator over torque has exceeded the torque limit.| Ensure that the actuator is not trying to rotate with more than 25% of its nominal torque. Then, press the push button (PB1) to trigger an auto-stroke and clear the alarm.

Hardware

| ****

1.  The NVM is corrupt.

2.  There is no magnet installed.

3.  The GMR sensor failed.

| 1.  Visually inspect the NVM IC, remove any dust or debris from it, then perform a power cycle.

2.  Ensure that the magnet is installed at a proper distance not touching the PCB or is not too far from

it. It is recommended to keep it 1-2mm away. Once confirmed, perform a power cycle.

3.  Visually inspect the TLI IC, remove any dust or debris from it, then perform a power cycle.

1. Remove the strain release NP NEP617-2 by turning it counterclockwise and slide it off the wires.
2. Insert the conduit attachment and turn it clockwise until it has been properly tightened onto the actuator attachment.
