Main additio na l funct io ns
Function Description
LEVEL ALARM
Operating if enabled, the opening or closing of the contact on the level probe indicates
that the additive in the tank has nished; the instrument deactivates the relays of the
set points and displays an alarm. Possibility of choosingbetween normally open contact
(default setting) or normally closed. Possibility of choosing triggering of the level alarm
for each measuring channel.
PROXIMITY SENSOR
The input can be activated to connect the proximity sensor which detects the ow in
the probe holder and enables triggering of the instrument. Possibility of choosing
between normally open contact (default setting) or normally closed. Possibility of
choosing to associate it to one or both pumps (default).
MINIMUM AND MAXIMUM ALARM
You may set the minimum and maximum thresholds of the measured quantity, beyond
which the instrument triggers an alarm. Possibility of choosing triggering of the
minimum and maximum alarm for each measuring channel. You may also associate
enabling of the alarm relay.
OVERDOSAGE ALARM
You may set an operating time limit for the pumps, beyond which, if the set-point values
are not reached, an alarm triggers and the device shuts down. The count includes the
service time, considering the actual operation of the pumps, therefore excluding pauses
in proportional operation. The relay output is always enabled.
ACTIVATION DELAY
It denes a time, starting from switch on, during which the device does not dose or
measure. When switched on, a countdown is displayed indicating the time remaining
until the measuring channelis activated. One for each measuring channel. Thisfunction
is useful when the sensors need a certain amount of time before detecting a reliable
measurement. Different delay values can be chosen for each measuring channel.
CLOCK To set the date and time. These parameters must be set if timer mode is activated.
TEMPERATURE PROBE
A two-wire PT100 probe may be connected to the instrument to compensate the
measurement.
ALARM RELAY SERVICES OUTPUT
This can be enabled through the menus of all the alarms, remotely indicating any alarm
situations.
Features: 1 exchange – 250V a.c. 5A (resistive load) and 1A (inductive load).
OUTPUT CURRENT (mA)
The instrument has an output in current (4-20 mA), directly proportional to the reading
of the measurement made by the instrument. By acting on the DOWN ARROW key
while it is displayed, you may view the current value present on the output.
TIMER Weekly and daily timer. 4 daily ON/OFF cycles. Set to the minute.
MULTI-LANGUAGE Language of the menus: Italian/English/German/Spanish/Portuguese/French
PASSWORD
A password can be set to separately protect CALIBRATION, SET-POINT, SETTINGS
and STANDBY
RESET Possibility of performing the reset to restore the default settings
PRIMING
It is possible to operate the pumps regardless of the measurement value detected by
the probes, for example to prime them during the installation procedure
