XW-PC-3 has been designed to use with XW1000 /XW1000A /XW1000B /XW1000C /XW1000D /XW1000E sensing cables, point sensors and normally open, dry contact devices (float switch, pressure or vacuum switch, optical probe with adapter, limit switch, etc.). Up to 1500m of sensor cable can be monitored by the XW-PC-3. With RS-485 technique, the distance can be even enlarged to 1200m. The leakage will make the relay working and trigger the alarm, then system will pinpoint the location.  



XW-PC-3 has five LED to indicate power, status and communications activity, as well as a relay with SPDT contacts. The XW-PC-3 can be used as a stand-alone leak detection alarm, or connected to a host system (computer, or control automation system) via MODBUS-RTU(ASCII), twisted pair RS-485 serial communication wiring.

The XW-PC-3 is designed for installation in ordinary (non-hazardous) areas. It has a range of applications, including data center, telecommunication rooms, HVAC equipment locations, pipes, electrical vaults, storage areas, tanks, and roofs.

Installation

In order to avoid damage the XW - PC - 3 leakage positioning controller, please retain the original packaging equipment, opened again until ready to install.

 

Installation position

XW-PC-3controller with a standard 35 mm DIN rail guide installation, the installation of the selected location should guarantee the module is not affected by the natural environment, the influence of the temperature limit or violent vibration.After installation shall be guaranteed not to trip over dangerous to walk, or collision damage caused XW - PC - 3 controller.XW-PC-3controller should be installed with wired control system within the range of a length of 1200 meters. Such as more than 1200 meters, please consult manufacturer connection method.。

 

Important:

XW-PC-3 modules for electronic equipment. Should follow the following preventive measures, in order to avoid damages to the electronic components.

  • Handle with care and avoid mechanical shock and impact。
  • Keep dry.
  • Avoid exposure to static electricity by touching a nearby piece of grounded equipment or water pipe prior to handling the XW-PC-3.
  • Avoid contact with metal filings, grease, pipe dope and other
