1. Pasiuna
The Network Enabled PAL-XD system consists of an electronic monitoring unit connected by jumper cable to a sensor cable. The sensor cable is continually monitored for leaks, breaks, shorts, and disconnects. The unit’s status is then communicated directly through LEDs and an audible alarm on the monitoring unit, to its web page, or by communications protocols connected either through RS-485 or Ethernet.
When using the PAL-XD the following general precautions should be observed:
1. RDeao d nthoits umsaen usaul bcsatriteuftuell y mbeaftoerriea lbse goirn nisnhgo irtn stcaultl atrieocno. mmended procedures. Understanding and following these instructions is essential to avoid installation problems.
2. Check packing list quantities with received items. Any shortages or damage to materials received should be reported immediately to the delivering carrier.
3. Care must be taken to store all PAL-XD components in a dry and protected area at all times. Electronic monitoring units should be wrapped and sealed with plastic.
4. Electrical work should be performed by a qualified electrician and conform to all local codes.
2. Teorya sa Operasyon
The PAL-XD Leak Detection Monitoring System is designed to monitor small areas for non-hazardous or ordinary location liquids using up to 500ft (150m) of PermAlert leak detection cable. Typical applications include unmanned equipment rooms, small, raised floor areas, and small tanks.
Using PermAlert’s advanced TDR technology, the PAL-XD system continuously monitors the connected sensor cables for dielectric changes resulting from the presence of any liquid able to permeate the cable. This means that the PAL-XD can be used to monitor any number of liquids including: water, pastorium based fuels, alcohols, acids, bases, dielectric coolants, and more.
Once the presence of a liquid is detected the unit will:
1. Turn on a LED indicator on the panel
2. Switch an internal “Leak” relay to active
3. Activate a horn
4. Update the Modbus status to LEAK
After detection, the PAL-XD will return to NORMAL only once the presence of liquid is no longer detected or the user re-initializes the cable.
3. Pag-instalar sa Cable
Each PAL-XD system is a complete kit that includes the monitoring unit, a wall plug power supply, and an application specific length of jumper cable, and sensor cable. The lengths of sensor and jumper cables may be pre-connectorized for easy installation or be provided for field termination to allow full customization.
In a typical installation, the sensor cable is placed around the perimeter of a room, a piece of equipment, or some other space that is to be monitored for leaks. The cable should be protected from people walking on it or equipment being placed on it.
The PAL-XD system has minimum length requirements as listed below and may be provided with convenient beginning of line and end of line termination assemblies for ease of installation.
Installation notes for all PAL-XD systems
- 30ft (10m) of JMP cable before any actively monitored sensing cable.
- The end of sensor cable must have 3ft (1m) of sensing cable at the end of the system folded back and sealed.
- IMPEDANCE jumper next to leak detection terminal must be set across the “Coax” pins.
