Det-Tronics SW9200x Slickwatch IR Oil Detection System - Manual (Page 8)

CAUTION
If power is to be disconnected for an extended peri-
od (e.g. over one week), the instrument should be
removed to a protected environment.
MOUNTING
The SW9200 transmitter and receiver are bolted side by
side to a user-supplied mounting platform. See Figure 4
for hole locations on the mounting plate. The transmitter
and receiver housings are attached to mounting plate as
shown in Figure 5. A suggested mounting framework is
illustrated in Figure 6.
The mounting framework must be securely stabilized to
assure retention of alignment over time and temperature
fluctuations. The framework should also be isolated
against external vibration.
A hinged mounting platform is recommended for ease of
service and adjustment. This type of platform has both a
“service” and an “operate” position, which facilitates
access to the controls without altering alignment.
INITIAL SETUP
When the inspection procedures and special precau-
tions detailed above have been carefully observed, the
initial setup of the SW9200 is accomplished by following
Steps 1 through 11 below:
CAUTION
Do not remove protective window covers until Step
7.
Do not mount instrument until power is available.
In order to minimize the possibility of condensation
forming inside the instrument, once mounted the
instrument should not be left without power for
extended periods of time.
1. Attach the transmitter and the receiver to the user-
supplied mounting plate with the 3/8-16 x 1-1/2”
stainless steel bolts, nuts and washers provided with
the instrument.
2. Connect external wiring as shown in Figure 7.
CAUTION
Power wire with AC voltage closest to ground
potential should be connected to terminal “N”.
Power wire with AC voltage furthest from ground
potential should be connected to terminal “L”.
Strip the insulation back 1/4 inch. Insert the stripped
wire into the terminal under the appropriate number.
Tighten the screw above the number by turning it
clockwise using a screwdriver with a 1/8” blade. All
terminals in the junction box are numbered. Low
voltage signal lines (RATIO, NUMERATOR and SIG-
NAL GROUND) and high voltage power lines from
the junction box should be in separate cables, if
possible. If the signal and power lines are not in
