5 Maintenance
DANGER
DANGER: contaminated parts
Contaminated parts can be detrimental to health and environment.
Before you begin to work, find out whether any parts are contami-
nated. Adhere to the relevant regulations and take the necessary
precautions when handling contaminated parts.
Caution
Caution: vacuum component
Dirt and damages impair the function of the vacuum component.
When handling vacuum components, take appropriate measures to
ensure cleanliness and prevent damages.
Caution
Caution: dirt sensitive area
Touching the product or parts thereof with bare hands increases the
desorption rate.
Always wear clean, lint-free gloves and use clean tools when working
in this area.
The electronics assembly of the PEG100 does not require any maintenance.
DANGER
A high tension which is dangerous when touched is applied to the
sensor in the PEG100. You must always switch off the supply voltage
for the PEG100 before starting any work on the gauge (even when
removing the PEG100 from the connection flange) so as to avoid
injury when inadvertently coming in to contact with the high tension.
In order to detach the electronics assembly and the magnet assembly (7/1) you
must loosen the two cross head screws which can be accessed through two holes
in the rear of the PEG100 by turning these by about 1.5 turns.
Then the electronics assembly and the magnet assembly (7/1) may be pulled off
from the sensor housing.
The magnet assembly (7/1) may drop down during the pulling off pro-
cess.
