Fitting the gauge head including the temperature
resistant gauge head cable
n
The gauge head including the temperature resistant
gauge head cable can be now inserted into the vacuum
chamber and bolted on.
Before connecting, we recommend to pump down the
system and if possible run a vacuum test or a direct leak
search.
For removing or replacing the gauge head proceed in the
reverse order. The plug must be unlocked in the gauge
head housing, and for this reason unscrew the cover (2/9)
first.
Especially note the pin assignment. Provide the connec-
tion with great care. Do not subject the pin contacts to
any bending forces! (Risk: damaging of the current
feedthrough/leak)
Live Voltages
If during operation the IM 540 suffers a malfunction then
a live voltage may be present at the gauge head cable
connection (CH 1, CH 2).
Affix the touch protection component to the IM 540
(BNC plug). The touch protection component is sup-
plied together with the gauge head cable.
