Both the digital indicators and dual set-point controllers
mount in a single panel cut out.
Instruments provided in “standard enclolures” fit the
same 2.75" (70 mm) round hole as used by Hastings,
Televac, Lesker, Varian and other analog meter instru-
ments. A ‘U’ shaped panel mounting clip is included with
the instrument. Instruments provided in 1/4 DIN
Enclosures fit a 92 mm x 92 mm cut out. Jack screws
are included with 1/4 DIN instruments.
1. Loosen the screws and remove the ‘U’ shaped bracket
from the standard enclosure or the 2 jack screws from
the sides of the 1/4 DIN enclosure. Feed the power and
gauge tube cables through the panel cutout and hold the
instrument flush against the panel.
2. Reinstall the ‘U’ clip or jack screws. Lightly tighten
(finger tight) the jack screws against back of the panel.
3. Adjust the front panel of the instrument to be square
and level and tighten jackscrews snugly. Do not over-
tighten.
4. Connect the power cord to an AC line power outlet of
the appropriate voltage. Power consumption is
approximately 2 watts.
5. Unless tagged, the instrument is shipped ready for
operation on 115 VAC. If modified at the factory for
230/240 volt use, the 115 volt connector will be removed
and the instrument tagged or marked for 230 volt opera-
tion. The customer will then be required to wire the
power cord to his connector as follows:
Black = Line White = Neutral Green = Ground
6. After the gauge tube is installed in the vacuum sys-
tem, connect the gauge tube cable to the gauge tube
(See the following section, “Gauge Tube Installation”, for
more information on installing the gauge tube).
7. For controllers, please refer to the section titled, “Relay
Output Connector Wiring” for information on connecting
the output relays. Information on connecting the analog
output signal for both the indicator and the controller
instruments is contained in the section titled, “Analog
Output Signal”.
