The remote enabling input is found on terminals 6-7 (terminal P16) of the control unit. A voltage-free
contact (switch, relay contact,...) must be connected to this input which, when closed, enables the
control unit to function. Instead, with the contact open, the control unit will remain powered in stand -by
to receive consent, without performing any operation.
Output 4-20mA
Current-Loop re-transmission of the pressure dP value, read by the control unit internal transducer, is
available at terminals 14-15 (terminal P14). This function is useful for sending information of the pressure
reading to a remote device (e.g. in a control room).
By accessing the parameters of the
Calibration/Test menu, the start and full scale
value of the 4-20mA output can be calibrated.
Input 4-20mA
An input in current-Loop is available (only in versions equipped) at terminals 12-13(terminal P12), for
connection to a triboelectric probe, which allows to measure the concentration of dust particles in the
environment.
Alarms
Two relays with voltage-free contact are available on the control unit, which will be activated on the
occurrence of an alarm, switching-over their contact from the rest condition to the opposite condition.
Using the secondary menu, the user can configure the status of the relay contact, the alarm mode and
any activation time.
dP minimum (if activated from the menu)
Replace Filters (if activated from the menu)
The alarm settings are accessible from the corresponding menu. The alarm event will be signalled in a
flashing manner also on the LCD. Using the “+” and “-” buttons, it will be possible to scroll the alarm
events occurring and they can be silenced by pressing the “RESET” button.
The internal piezoelectric buzzer will signal the event in conjunction with an alarm. However, the buzzer
can be disabled using the secondary menu.
