The Proper Installation & Maintenance of LPI-LCD-6.
THE LPI-LCD-6 IS TO BE INSTALLED AND SERVICED BY SERVICE PERSONNEL ONLY. NO OPERATOR / USER
SERVICEABLE PARTS.
All power and signals must be de-energised before connecting any wiring. Also refer to LPI-LCD-6 Layout &
Dimensions.
Mounting.
1) Make sure the surface of the mounting is clean before installing.
2) Do not subject to vibration or excess temperature or humidity variations.
3) Avoid mounting on cabinets with power control equipment.
4) To maintain compliance with the EMC Directives the LPI-LCD-6 is to be mounted on steel cabinet that must be
properly earthed, with appropriate input/output entry points and cabling.
5) Allow 10mm minimum clearance between the LPI-LCD-6 terminals and ANY conductive material.
Wiring.
1) All cables should be good quality overall screened INSTRUMENTATION CABLE with the screen earthed at one
end only.
2) Signal cables should be laid a minimum distance of 300mm from any power cables.
3) For 2 wire current loops and 2 wire voltage signals or 2 wire current signals, Austral Standard Cables B5102ES is
recommended. For 3 wire transmitters Austral Standard Cables B5103ES is recommended.
4) It is recommended that you do not ground current loops and only use power supplies with ungrounded outputs.
5) Lightning arrestors should be used when there is a danger from this source.
6) Refer to ‘Terminal Layout’ diagrams above for connection information.
Commissioning.
1) Once all the above conditions have been carried out and the wiring checked apply power to the LPI-LCD-6 loop and
allow five minutes for it to stabilize.
2) Take a low reading (approx. 10%) and high reading (approx. 90%) of the variable being measured by the
transducer supplying the signal to the LPI-LCD-6, and ensure that this agrees with the level being indicated by the
PLC or indicator, etc., that the LPI-LCD-6 is connected into. Adjust for any differences.
Maintenance.
1) Check the Sensor or Transducer supplying the signal to the LPI-LCD-6 for wear or damage and replace if defective.
2) Check the cables connected to the Sensor or Transducer.
3) Repeat (2) of Commissioning. Do it regularly - at least once per year.
