A770-10-880A - General description Description Data Mating connector plug; screw Phoenix part number SACC-M 8MR-4CON-M-SW connection, right angle Mating connector plug; solder Phoenix part number SACC-M 8MR-4CON-M connection, right angle Pump controller configuration All the configuration settings stored within the pump controller are retained when power to the pump is removed so that it is possible to use a separate system to configure the pump controller before fitting the pump to the application. -
Page 15: Installation
This publication is available on request by contacting Edwards. • Contact the local service centre or Edwards for more information regarding advice or assistance on installation. • Do not remove the temporary covers from the system inlet and exhaust until ready to connect to the vacuum or exhaust extraction system. -
Page 16: Mechanical Installation
A770-10-880A - Installation The pump is supplied fixed by metal brackets to a wooden pallet with a cardboard surround. These metal brackets should be removed and retained. • Take care when unpacking the pump to avoid excessive shocks which could damage the bearings and reduce the life of the pump. - Page 17 A770-10-880A - Installation WARNING: Install the pump in the vacuum system before connecting the pump to the power supply. This will ensure that the pump cannot operate and injure people during installation. WARNING: Topple hazard. Do not exceed the topple angle when moving the pump or the pump may fall over and injure people.
-
Page 18: Leak Test The System
Ensure that the sealing surfaces are clean and scratch-free. • Edwards recommends the use of an exhaust extraction system suitable for use with all process gases being pumped. Ensure that the exhaust extraction system cannot become blocked or obstructed when the pump is operating. -
Page 19: Electrical Installation
A770-10-880A - Installation Note: Ensure that the nitrogen supply conforms to the requirements given in Table 11 page 36 section. If it does not, the gas pipelines may become blocked or the dry pumping system may be damaged. Refer to Figure 1 on page 11, item (12) for location of the nitrogen purge port. -
Page 20: Connection For Remote Control And Monitoring
Parallel and serial control mode on page 22 for more information. To control the pump using the serial interface, please contact Edwards for further information. Additional safety equipment Install suitable measurement equipment in the nitrogen supply pipeline if the process tool/ control system needs to know the total flow rate of nitrogen to the pump for safety reasons. -
Page 21: Operation
A770-10-880A - Operation Operation Operation safety WARNING: Do not operate the pump with any parts of the enclosures removed or damaged as there may be a risk of an electric shock.
