  • Page 7: Warnings

    Leakwise sensors are floating devices. The installation must allow their free floatation and avoid submergence. Leakwise sensors are delicate instruments. Handle with care! Do not drop. Avoid damages to the cable/s during installation and operation, as this will void the IP67 sealing.

  • Page 8: Français

    Les détecteur Leakwise sont des dispositifs flottants. L'installation doit permettre leur flotation libre et éviter toute submersion. Les détecteur Leakwise sont des instruments délicats a manipuler avec soin! Ne pas lacher! Tout dommage créé au câble/s lors de l'installation et de l’utilisation, annulerait automatiquement l'étanchéité...

  • Page 9: System Description

    PS-220. The PS-220 signal processor is housed in a NEMA 4 (IP65) weather-proof or NEMA 7 or Exd Ex- proof enclosure, and powered by either 110 VAC or 220 VAC or 24 VDC or 12 VDC, at choice.

  • Page 11: Installation And Wiring

    SENSOR CABLE CAN BE EXTENDED THROUGH AN IP65 JUNCTION BOX. REFER TO DETAILS IN THE NEXT SECTION. Pass a power cable through the conduit from PS-220 to the local power source. Option: Pass the appropriate cable via the conduit between PS-220 and the central control room or remote controlled equipment.
  • Page 12 PS-220. BEWARE OF HIGH VOLTAGE 110 or 220VAC INSIDE ENCLOSURE! Turn power on. AIR / HIGH OIL light on the PS-220 should be on. If FAIL / DETECTOR DISCONNECTED light is on, refer to Section 5. Install the sensor properly in the sump. If there is water, WATER light on the PS-220 should be on.

  • Page 13: Maximum Cable Length Between Sensor And Ps-220

    Maximum Cable Length between Sensor and PS-220 The integral cable supplied with the sensor can be extended with another cable after a connection inside an IP65 junction box. ID-221 and all ID-223 sensors: 1. For Gas Group IIC hazardous area (Hydrogen): 150 meters maximum if 20 AWG wires (or thicker wires) are used.
  • Page 14 Select such a cable from a catalog or test its capacitance and inductance. A shielded cable is not required in most cases. Zener Safety Barriers for installation in hazardous area: Note: MTL 715+ and 710+ are obsolete. Use MTL 7715+ and 7710+. PS-220 RD1 USER GUIDE Revision 8 November 2017...

  • Page 15: Laboratory Calibration And Tests

    Laboratory Calibration and Tests Laboratory Calibration is a basic adjustment procedure to ensure correct operation of the system. Laboratory Calibration is carried out while the PS-220 enclosure is open, by adjusting the potentiometers inside. This procedure should be performed either as the next step after installation, when fast field calibration cannot be performed, or when trouble is suspected in the system.

  • Page 16: Typical Signals Of Leakwise Sensors

    Typical Signals of Leakwise Sensors Each Leakwise sensor has a cable with three wires named: DET+, DET-, DET Sig. DET+ : +12VDC supply in reference to DET-. Supplied current is the sum of the currents through the other two wires.
  • Page 17 Water / Oil Set Point. A larger distance means detection of a thicker oil layer (less sensitivity). 4. Oil / Air Set Point can be set as an Air indication threshold or as a Second Oil Alarm threshold. For Air indication set TP5 to 0.5V. PS-220 RD1 USER GUIDE Revision 8 November 2017...

  • Page 18: Laboratory Calibration Procedure

    Laboratory Calibration Procedure Calibration is carried out on the main board of PS-220 inside the open enclosure. All voltages measured in PS-220 board are DC. The negative probe of voltmeter is connected to TP2 (GND). NOTE: TP3 and TP4 measure the same signal, but TP4 is located after an additional buffer.

  • Page 20: Calibration Procedure For Optional 4-20Ma Output And Bar-Graph

    Calibration Procedure for OPTIONAL 4-20mA OUTPUT and BAR-GRAPH This procedure should be implemented after calibration of PS-220 main board. All adjustments are performed on the accessory board with open enclosure. The accessory board is mounted on the backside of the front panel.
  • Page 21 The 4-20mA output can be wired to the control room through the contacts of the Fail relay. During a failure, the control room will receive 0 mA as an indication of the failure. PS-220 RD1 USER GUIDE Revision 8 November 2017...

  • Page 23: Field Calibration

    Field Calibration Turn power on. One of the indicating lights on the front panel of PS-220 should turn on, and the FAIL / DETECTOR DISCONNECTED light should be off. The System has been pre-calibrated at the factory. The following is a fast field calibration procedure for small on-site adjustments. If only an oil detection sensitivity change is desired, refer directly to Paragraph 5.1.3.
  • Page 24 (For some demo units only: R2 is the calibration screw located next to AIR / HIGH OIL light). If AIR / HIGH OIL light is on: Turn R2 counter-clockwise till OIL light turns on and then slightly clockwise till AIR / HIGH OIL light turns on. PS-220 RD1 USER GUIDE Revision 8 November 2017...

  • Page 25: Built-In Test

    To check the PS-220, push TEST button for a few seconds, then release. The PS-220 will receive a ramping test signal instead of real sensor signal, and the indicating lights will turn on consecutively: AIR / HIGH OIL, OIL, then WATER.
