Adjusting the Minimum Pressure Switch Alarm (CONV.L.SWITCH)
The minimum pressure switch is positioned on the delivery manifold and must be set at the system
minimum pressure, about 0.5 bar below the starting pressure value of the last pump.
46
Function available only with systems with a
pressure sensor and only if the respective
alarm is enabled (previous parameter).
Delay time in seconds on blocking
intervention for minimum pressure.
MAX PRESSURE ALARM
Function available only with systems with a
sensor.
Maximum pressure beyond which all the
active pumps are switched off.
To disable, insert pressure = 0 bar
Function available only with systems with a
sensor and if the respective alarm is
enabled (previous parameter).
Delay time in seconds on blocking
intervention for exceeding maximum
pressure.
EXTERNAL FAULT ALARM
Configuration of the indication of an
external alarm connected to digital input
AUX2. Usually a temperature or voltage
overload alarm generated by an external
trip device.
P1 OVERLOAD ALARM
Intervention of thermal protection / PTC
pump 1
P2 OVERLOAD ALARM
Intervention of thermal protection / PTC
pump 2
P3 OVERLOAD ALARM
Intervention of thermal protection / PTC
pump 3
LOW WATER ALARM
Intervention of hardware protection for low
level/pressure on intake
From probe circuit HIGH. LOW, COM to
terminals 22 – 23- 24
Delay time in seconds to block pumps for
intervention of protection for low
level/pressure on intake.
CONVEYOR LIMIT
Tripping of protection against pump
operation below minimum pressure.
Signal arrives from minimum pressure switch
(CONV.L.SWITCH) connected to digital input
AUX3.
Resets the memory of the Alarms Log.
