Edwards IH Instruction Manual - Ideal Vacuum Products

• Refer to Section 6 to determine the cause of the fault and to rectify the fault.
6. Look at the pressure gauge in your inlet pipeline:
• If the pressure is increasing, the HCDP pump-motor terminal-box (and/or if you have an
iH1000 system, the HCMB pump-motor terminal-box) is incorrectly wired: immediately
shut down the iH system, correct the electrical wiring(refer to Section 3.16.2), then repeat
this procedure from Step 3 again.
• If the pressure is decreasing, continue at Step 7.
7. After you have commissioned the iH system:
• If you want to continue to operate the iH system, refer to Section 5.
• Otherwise, shut down the system,: refer to Section 5.10.
3.20.2 Configure and switch on an iH600 system
CAUTION
Ensure that the booster start delay is correctly adjusted for your installation. If it is not, you
may damage the iH when you start it up.
CAUTION
You can only switch on and configure an iH600 system if you have a Single Equipment
Monitor (SEM) connected to the iH system. If you do not have SEM, do not use the
following procedure; contact your supplier or BOC Edwards for advice.
CAUTION
Do not operate an iH600 system with the maximum inlet pressure for longer than the
maximum time specified in Table 2-1. If you do, the HCMB pump may overheat
Notes:
You will need a stop-watch to do the following procedure, which assumes that you are familiar
with the operation of the SEM; where necessary, refer to the manual supplied with the SEM.
You can only adjust the iH booster start delay up to a maximum of 255 seconds. If your required
delay is longer than 255 seconds, you must fit an iH600 Pressure Control Kit accessory: refer to
Section 8.4.3.
Operation of the iH system with high inlet pressure may result in shaft-seal pressure warnings
(refer to Table 6-1): the operation of the iH system will not be affected, and you can ignore these
warnings.
