Inlet Water Pressure/Flow Rate Measurement Sensor Management - IRTEC smart Manual De Instrucciones

With this selection, if the pressure drops below the minimum threshold, the machine stops, closes the inlet
valve and waits for the pressure to increase again, above the minimum threshold, to reopen the valve and
start the cycle again (the machine remains in the START status). There are no limits to the number of
stops.

Cycle stop and pressure alarm
With this selection, if the pressure drops below the minimum threshold, the machine stops, the valve is
closed and the pressure alarm is triggered. The machine goes into a STOP status and can only restart after
an operator has intervened.

Inlet water pressure/flow rate measurement sensor management.

On this page you must first select the type of sensor for detecting the machine inlet water pressure.

No pressure control device (figure 22), the machine is always ready to receive the START
command regardless of the presence or absence of water.

Pressure switch with mechanically calibrated digital contact (figure 23).

Analogue pressure transducer with minimum settable threshold (figure 24), in this case the
instrument full scale (normally indicated on it) and the minimum pressure threshold for starting the
work cycle must be set.
NB the pressure transducer must supply a 1-6V signal where 1=0Bar and 6V=FullScale Bar
set, if the electrical signal is less than 1V the system triggers a sensor damaged alarm.
