separate cables, the high voltage power wires (115
VAC line and Power Ground) must be shielded from
the signal lines for safety reasons. Any conduit
installed must be of a flexible, explosion-proof type
which will allow 180 degree rotation of the mounting
plate and instrument and allow adjustment of the
housings for optimum alignment.
WARNING
If both conduit entrances to the junction box are
not used, the unused entrance must be fitted
with an explosion-proof pipe plug with at least
five full threads engaged.
RATIO, NUMERATOR and SIGNAL GROUND wiring
from the junction box should be connected to exter-
nal readout devices of at least 5,000 ohms
impedance. If the 4-20 mA output is installed, the
loop resistance must be less than 500 ohms.
3.
Connect OIL ALARM relay and STATUS ALARM
relay signal terminals (4,5,6 and 7) to external read-
out devices (e.g. indicator lamps, alarm buzzers,
motors, computer interface, etc.). The Oil Alarm
relay contacts open when a film of oil is present on
the water surface. The Status Alarm relay contacts
open when an obstruction or instrument failure is
detected.
4.
Connect transmitter and receiver to the power
source. DO NOT apply power.
5.
In preparation for optical alignment, remove the
receiver window assembly by rotating it counter-
clockwise. Avoid touching the window with bare
hands. Move the window assembly to a safe place,
being careful not to scratch the window.
6.
Set the MODE selector switch on the front panel to
the ALIGN position and replace the window assem-
bly.
7.
Remove protective window covers from both the
transmitter and the receiver. Do not discard.
8.
Be sure that the cover bolts are tight. Check tight-
ness of junction boxes and window assemblies.
9.
Rotate both transmitter and receiver mounts 180
degrees so that the instrument is viewing the water
surface.
10. As power is first applied to the instrument, the trans-
mitter lamp should light and a faint rotation noise
may be heard within the receiver housing.
11. Allow at least one hour warmup time with the instru-
ment operating continuously before proceeding to
alignment.
NOTE
The instrument is designed for continuous opera-
tion. Excessive application and disconnection of
power to the transmitter will shorten the life of the
lamp.
