|Options on request. Contact us for other options|
|D16||RS485 serial line connection||With this option it is possible to connect the device to a PC by a serial line RS485 to check the running of the device and to set all its parameters by using the software ESAnet made by ESA Electronic Engineering Srl or by Profibus by using external converter.
• The line features are: • 9600 bit/sec • No parity bit • 1 stop bit • No flux control
|GSM1||GSM network connection for SMS sending in case of alarm||GSM network connection by Quad-Band modem 850/900/1800/1900 MHz. When an alarm switch On, the device send an SMS to the mobile phone number insert in set up with the indication of active alarm type (min. and max. dP alarms, dust emission alarms, electrovalves actiovation alarms). By sending an SMS to the SIM mobile phone number of the device iy is possible switch Off all the alarms and receive back a data string with some operating information: Alarms reset command: SMS text = !a Operating information datas sending command: SMS text = !i|
|A1b||Minimum (K1) and maximum (K2) dP alarms on separate relays||Minimum and maximum dP alarms act on 2 different relays: relay K1 for minimum dP-alarm, relay K2 for maximum dP-alarm.
• A: Relays
• B: Terminal board
• C: Minimum dP alarm on models with 3-digit display
• D: Minimum dP alarm on models with LCD display
• E: Maximum dP alarm on models with 3-digit display
• F: Maximum dP alarm on models with LCD display
|C11a||4÷20 mA output signal of dP readout||4÷20 mA output signal corresponding to the dP reading.
The signal is active, supplied at 12VDC by the device, the maximun drived load is 450 Ohm.
4mA = dP reading 0.00 kPa, 20 mA = dP reading equal to the full range requested.
If an external voltage is applied to C11a clamps the device will be damaged.
• A: Max 450 Ohm
|C13_10||dP full range 10.00 kPa = 100.0 mbar = 1012 mmH2O.||Maximum differential pressure value measurable by the device 10.00 kPa = 100.0 mbar = 1012 mmH2O.
With dP reading over 10 kPa the display shows 'E' instead of the numeric value of dP.
|C3||Differential pressure readout from internal transducer (max 10 kPa)|
|C7c1||Minimum dP alarm. Automatic reset.||If the dP readout is below the threshold set in Set up, the minimum dP alarm is activated.
The display shows the alarm condition code E8 (see the alarm description) or the dP readout and letter L alternatively, according to the model.
The corresponding alarm relay will signal its condition.
The alarm is automatically reset when the dP readout is above the threshold again.
With set value 'OFF' or 'E' (according to the model), the function is excluded.
NOTE: the minimum dP alarm is delayed by 60 seconds by default after the activation of the first cleaning cycle.
|C7d1||Maximum dP alarm. Automatic reset.||If the dP readout is above the threshold in Set up, the maximum dP alarm is activated. The display shows the alarm condition code E7 (see the alarm description) or the dP readout and letter H alternatively, according to the model.
The corresponding alarm relay will signal its condition. The alarm is automatically reset when the dP readout is below the alarm threshold again.
The activation of this alarm is delayed by 20 seconds by default.
|C8||dP zero readout regulation||In this set up code it is possible to adjust the zero reading of differential pressure.
In this function the display shows the dP reading and, with plant stops or air pipes not connected if the dP reading is not 0.00 kPa it is possible to adjust it by key A and C.
|D14c||Operation hours-counter||In Set up it is possible to visualize an hours counter.
This counter is always active in operating and it stops in Set up.
|DPa||Air connections 6x4 RILSAN pipe|
|SL||Multi language display||In Set up it is possible to select the language of all the descriptions showed by the display:
