3.4.3 Alarm outputs
Both the U3000 and U4000 models contain two programmable alarm outputs that are interfaced by opto-
isolated relays. The relay contacts are rated at a 48V (maximum voltage across the open contacts) and
500mA (maximum continuous current through the closed contacts).
The two alarm outputs can be individually configured to operate in one of four modes:
Activate at a predefined Low or High flow rate.
Activate when a specified Volume is measured.
Activate if a signal error is detected – either due to poor signal strength or complete signal loss.
Alarm Test mode.
