The Modul1000 has three maintenance counters which run independently from each
other. In detail:
1
Maintenance counter for air filter:
The default setting is 2500 operating hours. The maintenance counter can vary or it
can be switched off. In this way, it can be adjusted to the operating conditions of the
device.
2
Maintenance counter 5000 operating hours:
It serve for the inspection and cleaning of valve drives and the valve block.
3 Maintenance counter for 2 years
It is intended for the maintenance of the turbo-molecular pump TMH 071.
When the before mentioned maintenance intervals have expired, the control unit of
the Modul1000 will display a warning every time the device is switched on. The
message appears as long as the maintenance interval has been acknowledged. The
maintenance counter 2 is only enabled for the service steps II and III in the service
menu.
Notice:
To be able to claim for compensation for damage, the maintenance
schedule of the Modul1000 has to be observed. If necessary maintenance
works were not done, the claim for compensation for this component will
expire.
Fore Pump
The fore-vacuum pump is not included in the scope of delivery for the equipment.
Therefore, the maintenance intervals and the instructions required by the manufac-
turer of the fore-pump will be applied.
Damages on the Modul1000, which are clearly traceable to a malfunction of the fore
pump, cannot be claimed for compensation.
