PROPORTIONAL
from mA input
The pump doses in proportion to a 4-20 mA current signal coming from an
external transducer. The setting of maximum and minimum values can be set
in the respective set-up menu.
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.
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).
CLOCK
Possibility to set the date and time, parameters necessary if the mode with
timer (TIMER) is activated.
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).
TIMER
Weekly and daily timer. 16 cycles ON / OFF daily. Settable per minute
LANGUAGE
Language Selection menu. Italian / English
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.
