    2.2 STANDARD FEATURES The presence of options on request could nullify or modify the operating of standard features. Code Description Minimum and maximum dP alarms on same relay (K2) Minimum and maximum dP alarms act on the same relay. The display will specify the type of alarm. Relay Voltage ON (K1) If the device is supplied, relay K1 is activated and the terminal board contact is closed.
  • Page 3 JP2: Select the output voltage between 24, 115, 230 V (Only when the power supply is 115VAC or 230VAC). JP3: Select the output voltage between AC and DC only when JP2 is set to 24V. ATTENTION: set the same output voltage you have selected by means of the jumpers to adjust the trip threshold of the short-circuit.
  • Page 4 2.3 OPTION ON REQUEST The presence of options on request could nullify or modify the operating of standard features. Code Description Emission control by TRIBO-CHECK probe. Alarms on relay K2. 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 possible alarm situations that allow to find if there is a broken bag or a continuos emission over a set threshold.
  • Page 5 2.3 OPTION ON REQUEST The presence of options on request could nullify or modify the operating of standard features. Code Description Sensitivity for broken bag check If a bag is broken, whenever you activate the solenoid valve corresponding to this bag, this will produce a dust puff. The equipment can find out this failure and signal the row of bags where there is the breakage.
  • Page 6 2.3 OPTION ON REQUEST The presence of options on request could nullify or modify the operating of standard features. Code Description D12c High emission alarm. If the readout of the TC signal is above the value in set up code D12 the high emission alarm will be activated. The display will show the alarm condition code E4 (see alarm description) and the relay will signal the alarm condition.
