F074 - Level / pump controller

F074 - Level / pump controller
with one control output

The F074 is a basic level / pump controller that works with a preset value and two switch points to control a pump or valve. The low and high level switch points are entered as a percentage of the preset value to switch the device on / off. For pump control applications, the function can be inverted to empty a well. A stable level within a hysterese around the preset value is the result. The configuration of the Span, off-set and number of decimals is done through software functions, without any sensitive DIP-switches or trimmers. The display shows the actual level, preset value, high / low switch points and status.
On-screen engineering units are easily configured from a comprehensive selection.
A wide range of options further enhance this models capabilities, including Intrinsic Safety for hazardous area applications.

Features
• Level control: high / low switch points and a preset value can be set.
• Displays actual level, switch points, status and preset value.
• Switch points and preset value can be set by the operator or they can be passcode protected.
• One control output for on / off pump or value control.
• Functions for filling-up a container or emptying a well or tank.
• Level: six large 17mm (0.67") digits.
• Selectable on-screen engineering units for level:
ml, L, m³, GAL, USGAL, kg, lb, bbl or no unit.
• Selectable on-screen engineering units for height:
mm, cm, m, mtr, inch, ft, mmwk, mmwc, cmwk, cmwc, mwk, mwc, inwc, ftwc, mBar, Bar, PSI or no unit.
• Green or amber LED backlight with adjustable intensity.
• Auto backup of settings in EEPROM memory.
• Operational temperature: -40°C to +80°C (-40°F to 178°F).
• Very compact design for panel mount, wall mount or field mount applications.
• Rugged aluminum or GRP field mount enclosure IP67 / NEMA4X.

Applications
Basic on / off level control applications without PI(D) control requirements.
Also very suitable for applications where the required level changes frequently.
