Edwards IH Instruction Manual - Ideal Vacuum Products

On an iH600 or iH1000 system, the following alarms will cause only the HCMB pump to shut
down, whether 'run til crash' is selected or not:
• HCMB CURRENT HIGH/LOW * (error numbers 710 and 712).
• HCMB THERMISTOR HIGH (error number 912).
• - (error number 701) ✝ .
5.12Emergency stop
Notes:
The emergency stop switch is not an electrical isolator, unless the disconnect box accessory is
fitted (See Section 5.17).
The use of emergency stop will not automatically shut down the load lock pump (if fitted); you
must shut down the load lock pump separately.
To shut down the iH system in an emergency, press the emergency stop switch (Figure 1-7,
item 1) on the dashboard. Alternatively, you can operate the emergency stop controls in your
own control system if you have connected your emergency stop circuit to the iH system as
described in Section 3.15.
When emergency stop is selected:
• The HCDP pump (and the HCMB pump, on iH600 and iH1000 systems) is switched off.
• The solenoid-valve(s) in the Gas Module close, to switch off the supply of nitrogen to the
HCDP pump.
• The Pump Display Terminal will display 'STOP ACTIVATED'.
• The LED on the On button on the Pump Display Terminal (Figure 1-8, item 1) will go off.
5.13 Restart the HCMB pump after automatic pump shut-down
(iH600/iH1000 only)
WARNING
If a pump is automatically shut down, ensure that it is safe to restart before
you restart the pump
If the HCMB pump has been automatically shut down due to an alarm (see Section 5.11), use
the Switch On/Booster Pump menu to restart the HCMB pump after the alarm condition has
cleared.
