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).

UNITS/MODE |
|
From Mode |
press the and then the or to select Level, Range, |
Flow, HRT or |
Volume. |
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.
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. |
||
Volume, |
HRT |
or |
Flow gives the additional choice of volumetric units: |

Press to Calibration |

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 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 to return to Menu Selections.

CALIBRATION
- for Open Channel Flow
1. Before starting the calibration determine:
a) |
MAX RANGE |
= ____________________ |
|
(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 OCF 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 OCF 5.0 will not detect targets beyond user entered Max Range.
