5. e-Vision Installation
Unless prevented by other considerations, it is desirable to position the e-Vision
Control Electronics package horizontally, with the lettering on the side panels “right
side up”. This facilitates cooling of the electronics, as well as being cosmetically
optimized, and affords the best thermal stability during operation. However, it is
permissible to operate the unit in any orientation, and the user should consider
easy access to the vacuum chamber as more important in the mounting of the e-
Vision.
5.1 Installation
Rotate the locking ring on the stainless steel analyser connector so that the slot
lines up with the keyway on the connector tube. Hold the e-Vision
unit so that the
keyway lines up with the locating key on the analyser flange.
Gently slide the e-Vision
unit on to the analyser.
Take great care, the pins on the vacuum feedthrough are easily
damaged. DO NOT force the e-Vision
unit on to the analyser.
When all of the pins are engaged, push the e-Vision
firmly onto the analyser to
ensure electrical continuity. The last 3mm (1/8”) is important. When correctly fitted,
the front face of the stainless steel RF/analyser connector should butt up against
the analyser flange.
Finally, rotate the locking ring to lock the e-Vision
in place. You will not be able to
do this if the e-Vision
is not pushed fully onto the analyser.
5.2 Electrical connections
Insert the 15-way D-Type socket on the output lead of the power supply unit into
the 15-way D-Type plug labeled
“POWER”
on the rear panel of the e-Vision.
Attach the line cord to the power supply. The power supply will automatically set
itself to operate with the local line voltage.
When power is applied, the LED on the rear of the e-Vision
will illuminate.
Connect a cat5 patch lead to the socket marked
“ETHERNET”
. If a direct
connection to the host PC is required, use a crossover cable. If connecting via a
network hub, a standard patch lead may be used.
If required, connect your X-Trip signal cable to the socket marked
“X-TRIP”
. For
signal options, see Section 3.5.
