Additional functional principles
Function
Description
FLOW SWITCH
ALARM
The pump controls by means of the flow-status (available on request and inserted on the pump
delivery), the actual injections delivered, signalling any anomaly, by means of the LED alarm and
the switching the relevant relay (if enabled).
LEVEL ALARM
Operational if enabled in all functional modes, the opening or closing of the contact on the level
probe, indicates the end of the additive in the tank, the pump stops and the relay switches (if
enabled).
UNDERLOAD
ALARM
Operational if enabled in all functional modes,
the system controls the intake and in the absence of
liquid in the tank, of an inoperative valve, of the air inlet of the suction tube being disconnected etc.,
the pump will stop and the relay switches (if enabled).
OVERLOAD
ALARM
Operational if enabled in all functional modes,
the system checks the flow and in the event of
overpressure in the pump body, caused by an obstruction in the discharge line or by a high
operating pressure which exceeds the pump features,
the pump will stop and the relay switches (if
enabled).
TOO MANY
IMPULSES
ALARM
The pump, in 1xN (M) and PPM ml x m
3
mode, controls at all times the number of injections that
have yet to be carried out. If they are greater than an amount equal to 4 × N, where N is the
impulses to be delivered for each contact, the pump will go into alarm resulting in LED lights and the
intervention of the relevant relay.
MINIMUM AND
MAXIMUM
ALARM
In the instrument version you can set minimum and maximum thresholds on the measured quantity
exceeded which causes the pump to signal an alarm.
OVERDOSE
ALARM
In the instrument version you can set a continuous operation time threshold after which the pump
signals an alarm.
RELAY SERVICES
OUTPUT
Activated by the menu of all the above alarms, allows for remote signalling of alarms.
Features: 1 changeover - 250V a.c. 5 Amp (resistive load).
CURRENT
OUTPUT (mA)
The pump in the control configuration (pH, RX, Cl, ppm), has a current output (4-20 mA), directly
proportional to the reading of the measurement carried out by the instrument
TEMPERATURE
PROBE
A PT100 two-wire temperature probe can be connected to the pump.
CLOCK
Possibility to set the date and time, parameters necessary if the mode with timer (TIMER) is
activated.
PROXIMITY OR
LEVEL REMOTE
CONTROL
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).
In the case of control configuration, it is possible to activate the input for connection to the proximity
sensor which detects the passage of the flow in the probe holder and enables the operation of the
pump.
FREQUENCY
MAXIMUM
Possibility of reducing and setting the maximum frequency of the pump in accordance with the
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
MENU
In the control configuration it is possible to determine the level of complexity of the programming
menu: simplified and complete.
RESET
Ability to perform two types of reset: "soft" to reset the settings of all the functions, "hard" to
reconfigure the mode of use of the device (proportional or instrument) and to restore the factory
settings.
