Omega Products FSW-410 Installation Manual

FSW-410 Series

1.0 Install the FSW-410 by inserting the 1/2” MNPT threaded sensor tip into a tapped pipe or T fitting. Use Pipe Tape or Plumbers Putty on NPT threads to aid in sealing. Tighten firmly, but do not over tighten as this could damage the NPT threads and prevent proper sealing.

2.0 With provided connection cable disconnected, complete unit wiring by connecting the Brown wire to +24VDC supply and the Blue wire to common. The Black wire is now connected to the + side of your load. The - side or common side of the load is now connected to the ground.

. NOTE: Be sure that the common (ground) of the FSW-410 and the LOAD are the same. The white wire (if present) is not used.

3.0 Upon initial power-up the unit will provide a temporary output as the unit is adjusting to the zero flow rate of the media. After approximately 10-15 seconds the output will turn off. Once the unit output has turned off, the unit is ready for operation. Once the threshold of the unit set point (approx. .3-.4 meters/second) is reached the output will turn on.

4.0 As the FSW-410 unit also monitors the media temperature, the unit will provide a loss of signal if the temperature of the media goes above the threshold of the unit temperature set point (typically 50 or 70 Deg. C.), even with proper media flow.

NOTE:

Use caution while installing the FSW-410 so as not to damage the tip of the sensor. The electronics are embedded just behind the tip of the FSW-410 and denting or bottoming out of the tip could cause damage.

Maintenance is not required, as the FSW-410 has no moving parts. However, should the sensor become coated after a period of time in operation due to water or media conditions, simply wipe the probe tip with a soft cloth and alcohol.
