Operation
M561-00-880 Issue C
4 Operation
4.1 Start-up
The system is designed to ride through transient term power interruption and to automatically restart once the
power is restored.
Do not operate the pump if the pipeline is restricted or blocked as the pump will not operate correctly and may
be damaged.
Refer to Section 1.4.
1. Switch on the cooling-water and nitrogen supply.
2. Switch on the electrical supply.
3. Check that the exhaust-extraction system is not restricted, and that any valves in the exhaust-extraction system
are open.
The pump can be started using either the MicroTIM, the PDT or the front panel control.
Do not operate the system with the lifting eyebolts still fitted or with any enclosure panels
removed or damaged and do not touch any parts of the pump(s) when the system is on. Surfaces
of the pump(s) are very hot and can cause injury to people. In accordance with Semi S2, hot
surface warning labels are applied to the side panels of some iXH T variants because testing has
shown that accessible temperatures can exceed 65°C in small areas at worst case pressure
conditions at an ambient temperature of 40°C. Under normal process operating conditions and an
ambient below 25°C, accessible enclosure temperatures are unlikely to reach this level.
Do not operate the system with any enclosures removed or damaged. If you do there may be a risk
of an electric shock.
Ensure that it is safe to start the system. If you do not (and, for example, maintenance is being
performed on components downstream of the system), you could cause injury to people.
After the power is applied, all mains circuits will be energised.
The exhaust of T variant systems will heat up to maximum temperature as soon as the electrical
supply is switched on.
