Delay Time of Low Pressure Warning
When pressure feedback value is lower than the low pressure limit level, low pressure warning time will
start to count. If the value is higher than the low pressure limit level during the counting time, the warning
time will recount. It will jump to the warning signal “LoPb” when the counting time is over.
24-16
Delay Time of Low Pressure Error
When the warning signal of low pressure occurs and pressure feedback value is lower than the low
pressure limit level, low pressure shutdown time will start to count. If the value is higher than the low
pressure limit level during the counting time, the shutdown time will recount. It will jump to the error signal
“LPbFt” when the counting time is over.
Note: If user wouldn’t like to limit to the low pressure level, the low pressure warning time can be set to
zero, and then the low pressure limit function is disabled.
