OPERATING AND MAINTENANCE MANUAL
DIGI-PLUS SERIES CONTROLLER
1. GENERAL
Read carefully the instructions before installing this unit. Verify the technicalcharacteristics
of the motor in order to assure the compatibility with the device.
2. DESCRIPTION (diagram A)
DIGIPLUS is an electronic pump controller with integrated digital manometer an
instantaneous lecture of the motor load. It manages the start and stop of a single-phase
pump up to 2.2 kW (3 HP). It can operate in pressure+flow dependent mode or in
pressostatic mode. The start pressure -and the stop pressure in pressostatic mode- are
easily adjustable through the users control panel. This device protects the pump against
overload, minimal pressure and dry-running operation.
3. CLASSIFICATION AND TYPE
According to IEC 60730-1 and EN 60730-1 this unit is a control sensor device, electronic,
independent assembly, with action type 1B (microdisconnection). Operating value: I <20%
I learned. Pollution degree 2 (clean environment) or flow>2,5 l/min. Rated impulse voltage:
cat II / 2500V. Temperatures for ball test: enclousure (75) and PCB (125).
4. OPERATING CHARACTERISTICS (diagram C)
• 2 modes of operation: pressure dependent mode and pressure+flow dependent mode.
• Adjustable start and stop pressure.
• Integrated digital pressure gauge with bar and psi indication.
• Inner pressure transmitter.
• Integrated non-return valve.
• Dry-running protection with led-light for flow indication.
• Protection against minimum pressure.
• Overcurrent protection with automatic restore attempts.
• ART Fuction (Automatic Reset Test). When the device has stopped the pump by the
intervention of the dry-running protection system, the ART tries, with scheduled basis, to
re-start the pump in order to restore the water supply. See "ART. Automatic reset function".
• Manual start push-button (ENTER).
• Control panel with 3-digit display, LED indicator lights and push-buttons
• Volt-free contact for monitoring the alarms displayed in the screen (only version A).
• Available settings:
• Stand-by mode.
• Enable/Disable ART, duration and number of attempts.
