  • Page 13: Power Supply Options

    The LMPL20 offers the user the ability to set the LMPL20 and the RC20 control to a specific address. This is used in applications that involve multiple LMPL20’s and is used so the one remote will only work with the LMPL20 that is set to the same address.

  • Page 14: Maintenance And Care

    The external power port may be used to supply the LMPL20 with an external 12V power supply. The external 12V power supply can be used to power the LMPL20 without a battery pack installed, or can be used to charge a NiMH rechargeable battery pack if inserted in the LMPL20.
  • Page 15 Locate a previously level area to set the LMPL20. Level the LMPL20 and set the grade to precisely 0.000% Set two markers (A and B) in line with the laser. Marker “A” should be set 1’ (.3M) from front of the LMPL20, and Marker “B”...
  • Page 16 Attach the LM-PL20 to the trivet plate or position in the manhole on the correct feet. Care should be taken that the LMPL20 is positioned on the correct centerline. Use the three leveling screws to adjust the trivet plate to approximate level condition (not required when mounting on self centering feet with pre-poured inverts - as the invert should be at the correct elevation).
  • Page 17 Place the grade rod in the manhole at the correct elevation and position the laser at the correct height in relation to the grade rod. Note that the grade rod can be positioned on the top of the LMPL20 and a correction of - 2.78 inch (70.5mm) is required.
  • Page 18 (7" or 175mm). Finally to set the LMPL20 to the correct elevation for use, place the pipe target in the pipe using the target associated with the size of pipe you are setting. Then adjust the pipe until the laser beam is precisely in the center of the alignment center of the target.
  • Page 19 This will ensure accuracy in set up and allow one person to set the LMPL20 up for use. By using the LMPL20 keypad, it may be necessary to have a person at both the LMPL20 and target in order to guide the laser beam to the center of the target.
