Additional functional principles
Function Description
The pump controls by means of the flow-status (available on request and inserted on the pump
FLOW SWITCH
delivery), the actual injections delivered, signalling any anomaly, by means of the LED alarm and
ALARM
the switching the relevant relay (if enabled).
Operational if enabled in all functional modes, the opening or closing of the contact on the level
LEVEL ALARM probe, indicates the end of the additive in the tank, the pump stops and the relay switches (if
enabled).
Operational if enabled in all functional modes,
UNDERLOAD
liquid in the tank, of an inoperative valve, of the air inlet of the suction tube being disconnected etc.,
ALARM
the pump will stop and the relay switches (if enabled).
Operational if enabled in all functional modes,
OVERLOAD overpressure in the pump body, caused by an obstruction in the discharge line or by a high
ALARM operating pressure which exceeds the pump features,

have yet to be carried out. If they are greater than an amount equal to 4 × N, where N is the
IMPULSES
impulses to be delivered for each contact, the pump will go into alarm resulting in LED lights and the
ALARM
intervention of the relevant relay.
MINIMUM AND
In the instrument version you can set minimum and maximum thresholds on the measured quantity
MAXIMUM
exceeded which causes the pump to signal an alarm.
ALARM
OVERDOSE In the instrument version you can set a continuous operation time threshold after which the pump
ALARM signals an alarm.
RELAY SERVICES Activated by the menu of all the above alarms, allows for remote signalling of alarms.
OUTPUT Features: 1 changeover - 250V a.c. 5 Amp (resistive load).
CURRENT The pump in the control configuration (pH, RX, Cl, ppm), has a current output (4-20 mA), directly
OUTPUT (mA) proportional to the reading of the measurement carried out by the instrument
TEMPERATURE
A PT100 two-wire temperature probe can be connected to the pump.
PROBE
Possibility to set the date and time, parameters necessary if the mode with timer (TIMER) is
CLOCK
activated.
Remote monitoring of the state of activation of the pump (Start / Stop). Possibility of choosing
between a contact normally open or closed. (NORMAL or REVERSE polarity).
PROXIMITY OR
In the case of control configuration, it is possible to activate the input for connection to the proximity
LEVEL REMOTE
sensor which detects the passage of the flow in the probe holder and enables the operation of the
CONTROL
pump.
FREQUENCY Possibility of reducing and setting the maximum frequency of the pump in accordance with the
MAXIMUM needs of the system.
TIMER Weekly and daily timer. 16 cycles ON / OFF daily. Settable per minute
LANGUAGE Language Selection menu. Italian / English
TYPE OF In the control configuration it is possible to determine the level of complexity of the programming
MENU menu: simplified and complete.
Ability to perform two types of reset: "soft" to reset the settings of all the functions, "hard" to
RESET reconfigure the mode of use of the device (proportional or instrument) and to restore the factory
settings.
