Page 14: Storage
(see chapter “Dimensions”, page 41). 3.3 Storage Pfeiffer Vacuum recommends storing the products in their original transport packaging. Storing a new pump 1. Keep the pump wrapped in its protective envelope. 2. Always leave the inlet, the exhaust blanking plates in place. -
Page 15: Product Description
The pump is compatible with traces of corrosive gases. A purge gas stream protects low- and high- pressure ball bearings and dilutes trace amounts of corrosive gases. Please contact Pfeiffer Vacuum for more detailed information on specific applications. 4.2 Human/Machine Interface Fig. -
Page 16: Installation
Installation 5 Installation 5.1 Installation The pump needs to operate in a horizontal position resting on its feet, the pumping axis must be verti- cal, and the pump inlet must be on top. 1. Determine where the pump will be located. 2. Handle the pump using a hoist. 3. -

The gas purge consists of injecting an inert gas into the pump. In this manual, the inert gas will be called ‘nitrogen’, as it is the most commonly used gas. For more information about the type of purge gas, contact your Pfeiffer Vacuum service center. DANGER... -
Page 18: Check That The Installation Is Leaktight
Installation Version G A gas purge circuit protects the low- and high-pressure ball bearings and dilutes trace amounts of corro- sive gases. The pump must be connected to a dry and filtered nitrogen supply that has the required characteristics (see chapter “Nitrogen characteristics”). 1. -
Page 19: Customer Electrical Installation Protection
Installation Procedure for restarting the pump after a power failure To restart the pump: 1. switch off the main power (main switch at position O), 2. eliminate the cause of the fault, then 3. wait for about 15 seconds, 4. flip the main switch to position I. The pump has thermal sensors that prevent start-up at certain temperatures (see chapter “Preliminary precautions for use”). -

Installation ● remotely control the start and stop functions, ● set the rotation speed. The connector wiring is the customer’s responsibility. 5.5.1 Logic input wiring There are dry contact inputs. Do not add more connections than those provided: S1, S3, S4 and S5. Fig. -
Page 21: Wiring The Rs-485 Serial Link
Installation NOTICE S2 output wiring precautions ► Do not connect a relay between contacts 5 and 6 of the S2 output: the relay coil could create an induced current which may damage the frequency converter. ► Do not apply a current greater than 35 mA to the output: a greater current would damage the frequency converter. -

Page 25: Operation
● Do not drain the pump: this operation is carried out during pump overhaul by our serv- ice centers. Safety data sheets You can obtain the safety data sheets for operating fluids from Pfeiffer Vacuum on request, or from the Pfeiffer Vacuum Download Center. -
Page 26: Matrix Gas/Applications
Operation 4. Check that the inlet pressure is not higher than atmospheric pressure. If the pressure is too high, it can damage the product. 5. Check that the ambient temperature is well within the permitted operating range. 6. Check the exhaust line during pumping to prevent the risks related to excess overpressure. 6.2 Matrix gas/applications You are advised to use the appropriate pump version according to the applications and the nature of the gases pumped and apply the usual precautions to guarantee the reliability and safety of the procedure. -
Page 27: Local Mode Operation
Operation ● LOCAL The pump is controlled by a switch: I/O. The pump runs independently of the equipment into which it has been integrated. ● REMOTE The pump is remote controlled by opening or closing different dry contacts. Its rotation speed is configured on the terminals of the remote control connector (see chapter “Remote mode opera- tion”. -
Page 28: Operation In Rs-485 Link Mode
Operation Note: when the S1 contact is closed, sending the 'ACPON' or 'ACPOFF' command via the serial link doesn’t disturb the operation (‘context error’ response on serial link). Influence of rotation speed on pump performances Pump performances are guaranteed for a nominal speed of 100 Hz. Changing the rotation speed affects the pumping speed and the ultimate pressure of the pump. -
Page 29: Operation Monitoring
Operation 1. Isolate the pump in the pumping line (isolation valve at pump inlet, closed) and let it run for 1 hour with gas ballast or purge open. 2. Send an ‘ACPOFF’ order via the serial link: the pump stops. Restarting after emergency stop (using the equipment) The emergency stop is managed by the equipment in which the pump is integrated. -
