CONNECTIONS:
POWER INPUT: The standard model requires AC power input between 100 to 240 VAC 50/60Hz . No
adjustments are necessary for voltages within this range.
Optional DC input model requires 9-32 VDC/9 Watts. Connect to + and - terminals.
Optional Thermostat and Heater modules are available rated for 115 VAC or 230 VAC.
IMPORTANT NOTE: To comply with CSA/UL electrical safety standards, AC power input and relay
connection wires must have conduit entry to the instrument enclosure. Installation requires a switch,
overcurrent fuse or circuit breaker in the building (in close proximity to the equipment) that is marked
as the disconnect switch.
Risk of electric shock. Loosen cover screw to access connections. Only qualified personnel should
!
access connections.
Note: Use of instrumentation over 40°C ambient requires special field wiring.
Note: User replaceable fuse is 2 Amp 250V (T2AL250V).

Increasing damping slows the SLT 5.0's response to level changes
and is ideal to smooth the display and outputs in turbulent
conditions. Damping value is shown in percent (0-99%). Some
experimentation may be required to select the optimum damping
value. A value of 1% is recommended for most applications. For
fast level changes (up to ½ inch/sec - 13 mm/sec), a Damping
value of 1% is recommended.

Each SLT 5.0 Level Transmitter includes a noncontacting ultrasonic sensor. The sensor must be
installed in a position to obtain unobstructed echoes
from the liquid or material being measured.

SENSOR MOUNTING/LOCATION
- Open Channel Flow Applications
Each sensor is equipped with a 3/4 inch isolation coupling which MUST be used in your installation. A
threaded nipple or length of conduit may be used to position the sensor at the desired height. The sensor
should be hand-tightened by turning the sensor stem only. DO NOT use a wrench and do not over
tighten.
IMPORTANT: Follow the flume manufacturer’s directions for sensor location. The sensor should be
centered above the flume approach section and mounted 8"/203 mm (minimum) above the maximum
liquid level (depending on sensor model).
The sensor should be protected from physical damage and the sensor cable should be routed in a
separate metal conduit.
Because the sensor is equipped with a temperature sensor, it should be shielded from direct sunlight.
Use the PVC “isolation coupling” supplied with the sensor and hand-tighten the sensor/coupling
assembly onto your mounting stand. Do not clamp directly to the sensor or to the isolation coupling.

TYPICAL SENSOR POSITIONING
FOR FLUMES AND WEIRS
Always refer to the flume or weir manufacturer’s instructions for correct measurement point upstream
from the flume or weir. Location of the sensor is critical for accurate flow measurement.
If manufacturer’s instructions are not available, the following guidelines are generally accepted.
1. PARSHALL FLUME:
Position the sensor at 2/3 Approach as
illustrated above. Sensor height must be
8" (203 mm) or more above the highest
water level.
2. PALMER BOWLUS FLUMES:
Position the sensor at ½ the flume
Diameter upstream from the throat of
the flume. Sensor height must be 8" (203
mm) or more above the highest water
D
level.
3. V-NOTCH WEIRS
3x MAX. HEAD
Position the sensor at 3 x maximum Head

level.

POSITION
FLOW
WEIRPLATE
STILLING WELLS
Stilling wells are recommended to reduce the effects of turbulence as water flows through the flume or weir. The
SLT 5.0 sensor is centered over the stilling well. Sensor height must be 8" (203 mm) or more above the highest
water level. The well must be kept clean of sediment and deposits on the side walls.

Locate the sensor at the position upstream from the throat of the flume or weir plate as recommended by
the manufacturer. A technique for accurate sensor height adjustment is shown:

SLT 5.0 Level and Flow Monitor
ENCLOSURE INSTALLATION
Locate the enclosure within 20 ft (6 m) of the sensor (500 ft -150 m optional). The enclosure can be wall
mounted with the four mounting screws (included) or panel mounted with Option PM Panel Mount kit
from Greyline Instruments.
Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due to
overheating and condensate. In high humidity atmospheres, or where temperatures fall below freezing,
Option TH Enclosure Heater and Thermostat is recommended. Seal conduit entries to prevent moisture
from entering enclosure.
NEMA4X (IP66) WITH CLEAR COVER
1. Open hinged enclosure cover.

2. Insert #8 screws (supplied) through the four enclosure mounting holes
to secure the enclosure to the wall or mounting stand.
Additional conduit holes can be cut in the bottom of the enclosure when

holes.
DO NOT make conduit/wiring entries into the top of the enclosure.
ENCLOSURE
END VIEW
Note: This non-metallic enclosure does not automatically provide grounding between conduit
connections. Grounding must be provided as part of the installation. Ground in accordance with the
requirements of the National Electrical Code. System grounding is provided by connecting grounding
wires from all conduit entries to the steel mounting plate or another point which provides continuity.

SENSOR INTRINSIC SAFETY
(OPTION ISB)
When connected through Intrinsic Safety Barriers, Greyline PZ** Series sensors are certified for
installation in a hazardous location rated:
Class I, Groups C,D
Class II, Groups E,F,G
Class III
The Intrinsic Safety Barrier may be ordered with the Greyline instrument and is supplied mounted in the
Greyline instrument enclosure. Replacement barrier fuses (Part No. ISB- 011239) may be purchased
separately. The instrument enclosure containing the ISB Intrinsic Safety Barrier must be installed in a
non-hazardous location.
Page 36
GN3SPEC-ISB-03
The intrinsic safetybarrier
assemblies installed in the
OCF 5.0/SLT 5.0/PSL 5.0
limit the voltage and current
supplied to the transducers
to the values listed under
‘Barrier Specifications’. To
safely install a Greyline
transducer certified for use in
hazardous locations you
must refer to the installation
drawings/specifications of
the certified transducer.

ENCLOSURE HEATER AND THERMOSTAT - Option TH
Instruments can be factory-equipped with an Enclosure Heater and Thermostat or the module can be
customer-installed. The Thermostat is factory set to turn ON at 40°F (4.5°C) and OFF at 60°F (15.5°C).
Power consumption is 15 Watts.
TO AC POWER SUPPLY
ENCLOSURE SUNSCREEN - Option SCR
Do not mount instrument electronics in direct sunlight. Overheating will reduce the life of electronic
components and condensate may form during the heat/cool cycles and cause electrical shorts.
11"/280 mm
Note:
Exposure to direct sunlight can cause
overheating and moisture condensation
which will reduce the operating life of
electronics.
Protect Instruments from direct sunlight
with this iridite finished aluminumsun
screen (Greyline Option SCR).
Seal conduit entries with caulking
compound to further reduce moisture
condensation.

POWER INPUT OPTION
9-32VDC
SLT 5.0 Level & Flow Monitors may be ordered factory-configured for 9-32VDC power input.
QUICK BENCH TEST:
Connect Sensor as shown below, then Power. When properly connected figures will show on the large
LCD display. Test operation of the SLT 5.0 by holding the sensor steadily and aiming at a flat, stable
target 12 to 28" (305 to 711 mm) away from the end of the sensor. Allow a few seconds for the SLT 5.0
to lock onto the target before displaying its distance. The SLT 5.0 will now display Range in ft or cm
(factory calibration).
CONNECTIONS:
POWER INPUT: Connect 9-32VDC/0.5 Amps to the + and - terminals. The Power Input GND must be
connected to the nearest Ground pole. A 1 amp fuse in line is recommended.
