Some 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
	GSM2	GSM network connection for datas sending to database ESAWEB	GSM network connection by Quad-Band modem 850/900/1800/1900 MHz. The equipment sends some operating data to a database at regular time intervals By accessing the web page via PC, tablet or smartphone it is possible to view and download the stored data. In the event of alarms, data is written to the database even if outside the established time interval.
Video	Standard features
	A2a	Relay Voltage ON (K1)	If the device is supplied, relay K1 is activated and the terminal board contact is closed. In case of power failure, this contact is open. • A: Relays • B: Terminal board
	C10	dP threshold plant On/Off	dP reading > threshold = plant operating, hours counter active dP reading < threshold = plant Off, hours counter disactivated With plat Off minimum dP alarm does not operate.
	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)
	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.
	D11c	Emission control by TRIBO-CHECK probe.	By connecting the Tribo-Check probe to the device it is possible to keep under control the dust emission in the duct. The TC probe management contain some function and different alarm situations that allow to find if there is a broken bag or a continuos emission over a set threshold. If there is an alarm situation the output relay contact indicate it and on the display it is possible to check the kind of alarm.
	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.
	D17	TC probe readout zero regulation (-9÷+9 points)	In set up function code 21 it is possible to adjust the zero reading of the signal from TC probe. In this function the display shows the reading of the TC probe and, with plant stops and without dust in the duct, the reading must be 00 mg/m3. If it is different it is possible to adjust it by using key A and C.
	D18	Emission readout setup in mg/m3	It is possible to adjust the readout of the TC probe in set up function 22 so that the display will show the exact value of emissions expressed in mg/m3. The display will show the numeric value corresponding to a 20 mA signal from the TC probe (20 default value). For this regulation you shall enter a well-known dust quantity in the duct (e.g. 10 mg/m3) and check the readout of the operating equipment on the display. • Refer to the documentation for more information
	D19	Mean TC probe readout time	In Setup it is possible to set a mean time of the TC probe reading. This function is used to cut sporadic emission peak and to have a stable reading on the display.
	D20	TC probe signal readout in mA	In set up function 27 the reading of the signal from TC probe in mA is shown. The range of the signal is 4÷20 mA.
	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: • Italian • English • French • German • Spanish
	T01	Temperature control via external sensor	In set up it is possible to include or exclude a temperature control from an external sensor. In the external temperature sensor it must be a 2-wire type that can be powered at 24VDC or 12VDC by the instrument and must provide a 4 ÷ 20 mA signal (4mA = 0 ° C, 20 mA = T03_xx)
	T03	Temperature probe signal reading in mA	In set up, the signal from the temperature probe expressed in mA is displayed. Reading scale 4 ÷ 20 mA
	T04_10	Full scale temperature reading 100 ° C	Maximum measurable temperature value equal to 100 ° C. External temperature sensor scale (4mA = 0 ° C, 20 mA = 100 ° C)
