	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
	LC2	Transparent membrane for keyboard IP65	Transparent PVC membrane to put on the device to protect the keypad. The degree protection of this membrane is IP65.
Video	Standard features
	A1a	Minimum and maximum dP alarms on the same relay (K2)	Minimum and maximum dP alarms act on the same relay. The display will specify the type of 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
	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: • Italian • English • French • German • Spanish
