2 | Product Description Product Description Suction connection Electrical connection (+V Batt Discharge connection 6-pole HDSCS connector (CAN) Nameplate Pressure relief valve NOTE Technical term. In this instruction manual, we consider that the term ‘machine’ refers to the ‘vacuum pump’. 2.1 Operating Principle The machine works on the claw principle.
Conveying of other media leads to an increased thermal and/or mechanical load on the machine and is permissible only after a consultation with Busch. The machine is intended for the placement in a non-potentially explosive environment. Permitted environmental conditions, see Technical Data [► 16].
• Make sure that all provided covers, guards, hoods, etc. are mounted. If the machine is installed at an altitude greater than 1000 meters above sea level: • Contact your Busch representative, the motor should be derated or the ambient temperature limited.
In case of very long connection lines it is advisable to use larger line sizes in order to avoid a loss of efficiency. Seek advice from your Busch representative. 5.2.1 Suction Connection WARNING Unprotected connection.
• Electrical installation work must only be executed by qualified personnel. • Make sure that the motor of the machine will not be affected by electric or electro- magnetic disturbance from the mains; if necessary seek advice from Busch. • Electrically connect the machine...

6 | Commissioning 6.1 Relief Valve Adjustment The factory setting of the relief valve is set at 600 hPa (mbar) absolute for a permanent usage. In case of cycling one, can be adjusted down to 450 hPa (mbar) absolute. To proceed, install the vacuum pump on a pneumatic bench with an absolute pressure sensor, an inlet valve and, if available, a volume flow sensor set at the outlet.
Commissioning | 6 6.2 Standard Version The machine starts automatically with maximum speed as soon as electrical power is supplied. 6.3 Version with Analogue Speed Control The electronic is automatically activated as soon as electrical power is supplied. The speed can be controlled by a potentiometer connected to terminal 1 (KL15) on the HDSC connector (CON).

6 | Commissioning Power-On Bit After startup a power-on bit is set in the CAN status frame for one second. The power- on bit can be used to identify unexpected resets/restarts. Loss of CAN Communication If a loss of CAN communication occurs the reference value for mass flow will be set to 100 g/min.
