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: 9-32 VDC. 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).

RUN
The main display shows the units selected from the Units/Mode menu, Level,
Range, Flow, HRT, and Volume rate being measured, TOTALIZER and RELAY
states. The OCF 5.0 will start-up with this display and will return to this screen
after a timeout if keys are not pressed in other menus.
MESSAGE
³
Press from the RUN display to view status of the data logger and error/warning
messages provided by the instrument. The word
Message will appear on the
RUN display if error messages are being generated by the instrument. Refer to the
manual section Error/Warning Messages for a description. Press to return to the
main display.
STATUS
³
Press from the RUN display to view instrument status. Range will be displayed
in linear units.
Tot Displays the current totalizer reading.
EC Displays echo confidence.
Relays Energized relays will display as a white character on a black
background.
24 HR LOG
Press from the RUN display to view a formatted flow report from instruments
with a built-in data logger. Press to scroll down one day or repeatedly to scroll
to a specific date. Up to 365 days can be stored. Newest date will overwrite the
oldest. Press to return to the main display.

UNITS/MODE
From
Flow, HRT or Volume.
Mode press the and then the or to select Level, Range,
Range 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.
Level used to measure tank level in linear units, or "Head" in an open
channel for comparison with flow tables.
m
Volume displays tank inventory in engineering units.
HRT select Horizontal Round Tank mode to calculate and display volume
units in a horizontal round tank.
Flow calculates open channel flow through a flume or weir.
L
Volume, HRT or Flow gives the additional choice of volumetric units:
ft3 - cubic feet
USG - US gallons
USMG - US million gallons (FLOW only)
IG - Imperial gallons
F
IMG - Imperial million gallons (FLOW only)
m3 - cubic meters
L - liters
bbl - U.S. oil barrel
Press to store the selection, then to the next menu item and to enter.

Temperature press and then or to select C or F (Centigrade or
Fahrenheit).

CALIBRATION
Press 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 fro m 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 OCF 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 and for
fast level changes (up to ½ inch/sec - 13 mm/sec).
LOE Time Press and or to change the number of seconds without
receiving an echo before the OCF 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.
Press from the
Units/Mode display to return to Menu Selections.
