Low press. alarm
N° resets 3
Start bypass 120 s
Sets the parameters for activating the low pressure alarm.
Number of times the alarm has triggered in the previous hour and been reset
automatically within the set period, the next time the alarm triggers it must be
reset manually.
Alarm by-pass time before the motor starts.
