Page 3 of 24 Notes on this manual ® You have decided for the control unit «PLUS» for the leak test system LEAK-MASTER EASY from WITT-GASETECHNIK. With this manual, we would like to provide you with all the information necessary for safe, correct setting up and installation, commissioning, operation and checking of the control unit «PLUS».
The liability for the function of the unit passes in all cases to the owner or operating organisation as far as the unit is operated by persons who do not belong to WITT Service, is incorrectly maintained or repaired, or if the unit is used in a manner that does not comply with the intended usage of the unit or is contrary to the applicable regulations.
The compounds for vacuum generation and setting of the LME will still be used. The control unit «PLUS» takes over the function of the ball valve (6) in the compressed air supply. In addition, the vacuum level need not be set by means of the operating pressure regulator (5). Instead of that the reached vacuum is measured by a pressure transmitter (PIT).
Note! Perform a visual inspection for external damage and damage to cables / tubes (nicks, dam- age to the insulation). The control unit «PLUS» is supplied ready to use. It must be correctly transported. Place for setting up ...
Insert the hose into the plug connection as far as possible. The arrestor will lock the hose automatically. ® Connect the control unit «PLUS» to a Leak-Master Easy If a 12 mm hose is used for the compressed air supply of the LME to be connected, first install both adaptors as described in Section 5.4.1.
Connect one adaptor to the compressed air connection of the control unit «PLUS» by means of a short peace (approx. 5 cm) of 8 mm hose. Connect the other adaptor to the compressed air connection of the LME by means of a short peace (approx.
