7. Opening and closing of the vibration control unit
The user must switch off the power supply, before opening the measurement unit. To open
the unit the user needs a 0,9mm type of wrench “inbus - key“ and a forehead key with two-
bore nut, with size of 4mm. The case cover is ensured with a M2 screw. These must be
loosened before opening of the case cover, with an “inbus - key”. After adjustment of the unit,
please control the position of the DIP-switches
Before closing the unit the O-Ring must be examine. You have to insert a new O-Ring
(43 x 2mm, LT170 – original spare part) if the old one is brittle, deformed, damaged or
already a few month in use.
Please pay attention that the thread and the interior room is oil- and dirt- free. Cleaning
around and inside the unit should be done only with clean and dry cloth. The closing and the
sealing of the unit is done after app. seven pitches of cover-nut thread, and ensured via the
M2 screw.
Advises for dismantling
Before dismantling the measurement unit, the power supply must be switched off. The
