5.
Ensure that the exhaust-extraction system is not blocked (for example, that valves in the
exhaust-extraction system are open).
6.
Ensure that all openings to atmospheric pressure in the foreline vacuum system are closed,
then switch on the iL system and simultaneously start the stop-watch.
7.
If the iL system starts and continues to operate, continue at Step 8. If a warning or alarm
condition is indicated (for example, a warning or alarm message is displayed on the SPM or
shown on the Pump Display Module):
•
Shut down the iL system: refer to Section 5.8.
•
Refer to Section 6 to determine the cause of the fault and to rectify the fault, then repeat
this procedure from Step 5.
8.
Look at the pressure gauge in your inlet pipeline:
•
If the pressure is increasing, the LCDP pump-motor terminal-box is incorrectly wired:
immediately shut down the iL system, correct the electrical wiring (refer to
Section 3.16.2), then repeat this procedure from Step 5 again.
•
If the pressure is decreasing, leave the iL system to operate and take note of the time
taken to pump down to 5 mbar (5 x 10
2
Pa), then continue at Step 9.
9.
Stop the iL system and isolate it from the electrical supply.
10. Add 10% to the time noted in Step 8, to give the required booster start delay for your
installation.
11. If the required booster start delay is less than or equal to 30 seconds, continue at Step 13.
12. If the required booster start delay is greater than 30 seconds, use the SPM to edit and save the
original configuration set uploaded from the iL (the set saved as, for example, "iL600"): set
the BOOSTER START DELAY of BOOSTER PUMP CONTROL to the required booster start
delay time.
13. Use the SPM to download the original configuration set (with file name, for example, of
"iL600") to the iL system.
14. Start up the iL system again and at the same time start the stop-watch. Watch the pressure
gauge in your inlet pipeline. The LCDP pump will start and the pressure will start to reduce.
After the booster start delay time, the LCMB pump will start (at an inlet pressure of
approximately 5 mbar, 5 x 10
2
Pa):
•
If the pressure increases or does not decrease any further when the LCMB pump starts,
the LCMB pump-motor terminal-box is incorrectly wired: immediately shut down the
iL system, correct the electrical wiring (refer to Section 3.16.2), then repeat this
procedure from this step (Step 14) again.
•
If the pressure continues to decrease after the LCMB pump starts, continue at Step 15.
15. After you have commissioned the iL system:
•
If you want to continue to operate the iL system, refer to Section 5.
•
Otherwise, shut down the system: refer to Section 5.8.
