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).

From
Flow, HRT or Volume.
Mode press the and then the or to select Level, Range,
Range mode displays distance from the sensor to the target or liquid surface
like a tape measure. Range mode is useful to measure the exact
distance from the sensor to the zero level during calibration, or to
monitor "outage" or free space in a tank.
Level mode can be used to measure tank level in linear units, or "Head"
m
(height of flow) in an open channel for comparison with a flume
manufacturer's flow tables.
Volume Volume mode displays tank inventory in engineering units like
gallons or liters.
HRT Horizontal Round Tank mode sets the SLT 5.0 to calculate and
display volume units in a horizontal round tank.
L
Flow mode is for open channel flow through a flume or weir.
From
Volume HRT or Flow press to make your selection. (Range or
Level mode will bypass the Volume units selection menu). Volume Hrt or Flow
modes will give you the additional choice of volumetric units:
F
ft3 - cubic feet
USG - US gallons
USMG - US million gallons (FLOW only)
IG - Imperial gallons
IMG - Imperial million gallons (FLOW only)
m3 - cubic meters
L - liters
bbl - U.S. oil barrel

CALIBRATION
Press the to
Calibration and to enter. Use or to position
before each menu item and to enter. When settings are completed press to
store and return to the Calibration menu.
Min Range Distance from the sensor face to highest expected level.
Max Range Distance from sensor to Zero level.
MaxVol For Volume and HRT mode only. Enter the maximum volume of
the vertical or horizontal tank.
Damping Minimum damping allows fast response to level changes.
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.
LOE Time Press and or to change the number of seconds without
receiving an echo before the SLT 5.0 displays ECHO LOSS, and
Control relays change state as calibrated under Relay Parameters.
Factory default is 30 seconds and is recommended for most
applications, Minimum is 1 second and maximum is 99 seconds.

- for Level/Inventory Applications
1. Before starting the calibration determine:
a) MAX RANGE = ________________
(Maximum range = distance from Sensor to Zero level)
b) MAX LEVEL = ________________
(Maximum level of product being measured)
c) MIN RANGE = ________________
(Distance from sensor to Max Level)
Minimum range = MAX RANGE - MAX LEVEL
(must be at least 8" / 203 mm depending on sensor model)
2. Check the maximum range with the sensor installed by:
a) When liquid is at zero level press to view the Range reading in the
Status menu. Use this range measured by the SLT 5.0 as the Max Range
setting.
or
b) Carefully measure distance from sensor to zero level with a tape measure,
and use this measurement as the Max Range setting.
MINIMUM RANGE:
At CALIBRATION
- Press to get to Min Range
- Press to move the cursor under the digits
- Use or to set th e minimum range
Note: Min Range must be at least 12" (30.5 cm) for PZ32T sensors, 16" (40.6 cm)
for PZ52T and PZ34 sensors and 8" for PZ15 sensors. For correct tank volume
calculation in Hrt mode Min Range must be the actual distance from the end of
the sensor to the top of the tank.
MAXIMUM R A NGE:
Press to get to Max Range
Enter Max Range determined above.

1. Before starting the calibration determine:

(Maximum range = distance from the Sensor to Zero flow point)
b) MAX LEVEL = ____________________
(Maximum level of flow through flume or weir)
c) MIN RANGE = __________________
(Distance from sensor to Max Level)
Minimum range = MAX RANGE - MAX LEVEL
(must be at least 8" / 20.3 cm depending on sensor model).
2. Check the maximum range with the sensor installed by:
a) When liquid is at zero level press to view the Range reading in the
Status menu. Use this range measured by the SLT 5.0 as the Max Range
setting.
or
b) Carefully measure distance from sensor to zero level with a tape measure,
and use this measurement as the Max Range setting.
NOTE
: The SLT 5.0 will not detect targets beyond user entered MaxRg.
