5. FUNCTIONING AND USE
5.1 Command description
Remote control panel
Fig. 5.1
Commands and indications of the remote panel are the following:
• PUMP 1: It is a selector. It allows the starting of the pump 1.
• PUMP 2: It is a selector. It allows the starting of the pump 2.
• AUT WASHING: It is a selector. It allows the starting of the automatic washing procedure when the unit
is stopped.
• START: It is a push-button used to start the unit.
• STOP: It is a push-button used to stop the unit. It includes a lamp that recognizes different alarm
conditions.
• WASHING It is just a lamp. It is “on” during the automatic washing of the unit.
The STOP lamp identifies the following alarm conditions:
• Blinking light (slow period – 1 sec.) It identifies a low-pressure alarm, recognized after the pump 2
starting. This alarm switches off automatically the system.
It is necessary to recognize the alarm (pushing STOP) and eliminate the origin of the faulty condition.
• Blinking light (fast period – 0,5 sec.) It identifies either the high pressure (on pump 2) or the absence
of cycling (no signals from the probe-signal pressure switch). This alarm switches off automatically the
system as well.
It is necessary to recognize the alarm (pushing STOP) and eliminate the origin of the faulty condition. If
the fault is related to a signal pressure switch malfunctioning, it is possible to start the system by
activating the by-pass selector.
