Chap. 8 - UNITS WITH PERIODIC AUTOTEST
When it is foreseen that a compression unit may stay inactive for long periods during which the pump will never be
started up and to avoid inconvenient working due to the inactivity (weld, mechanic seal, etc..) it is advisable to provide
the machine with devices for the periodic starting of the pump and for the signaling of possible damages.
These additionally have the followings devices:
1) weekly planner
2) solenoid valve
3) automatic pressure switch
4) acoustic alarm
Description of the operation
The weekly planner is added to the switchboard and programmed so that the time of the day and week are preset and
hence the program for the startup of sequential pumping is enabled in the following order:
solenoid valve opens and pump n.1 is started; after one minute the solenoid valve closes and the pump stops. If the
pump doesn't work correctly, the opening of the solenoid valve gives rise to a circuit pressure lowering and the automatic
pressure switch, which closes its contact after the delay time is set, enabling the anomaly sequence: the acoustic
alarm rings and the following message appears on the keyboard display:
