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
ALARM
and 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
absence of liquid in the tank, of an inoperative valve, of the air inlet of the suction tube being
ALARM
disconnected etc.,
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,
switches (if enabled).
The pump, in 1xN (M) and PPM ml x m
TOO MANY
that have yet to be carried out. If they are greater than an amount equal to 4 × N, where N is
IMPULSES
the impulses to be delivered for each contact, the pump will go into alarm resulting in LED
ALARM
lights and the intervention of the relevant relay.
MINIMUM AND
In the instrument version you can set minimum and maximum thresholds on the measured
MAXIMUM
quantity 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
ALARM
pump signals an alarm.
RELAY
Activated by the menu of all the above alarms, allows for remote signalling of alarms.
SERVICES
Features: 1 changeover - 250V a.c. 5 Amp (resistive load).
OUTPUT
CURRENT The pump in the control configuration (pH, RX, Cl, ppm), has a current output (4-20 mA),
OUTPUT (mA)
directly 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
LEVEL REMOTE
proximity sensor which detects the passage of the flow in the probe holder and enables the
CONTROL
operation of the 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
MENU
programming 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.
the pump will stop and the relay switches (if enabled).
the system checks the flow and in the event of
mode, controls at all times the number of injections
3
the system controls the intake and in the
the pump will stop and the relay
