Alarms And Malfunctions - BlueBox Datatech Installation, Use And Maintenance Manual

6.5 Alarms and malfunctions

Possible malfunctions will trigger the protective devices and safety devices of the unit before serious faults occur.
All the "warnings" and "alarms" are recorded in the memory of the control and displayed on the display of the unit.
Before resetting an alarm, the cause that triggered it must be found and eliminated.
An alarm going off repeatedly quickly leads to serious damage to the unit.
Refer to the manual of the control for the alarms and warnings that appear on the display of the unit.
In case of anomalies not handled by the control panel, refer to the following troubleshooting section.
This troubleshooting section does not include causes due to deliberate work or tampering or particularly serious malfun-
ctions, for which a thorough analysis is necessary.

LIKELY CAUSE
No mains voltage.
No voltage to the auxiliary circuit.
The unit is switched off from the di-
splay and the display is disconnected
or not working.
The control is not working.
The connection of the display to the
control is disconnected.
The display is not working.
The weight of the unit is not distributed
evenly on the base.
Operation of the system pump outside
its performance curve with excessive
water flow rate.
Presence of air in the system.
Opening of the valve due to failure of
the protective devices to operate.
Opening of the valve due to overtem-
perature.
Bedding in the mechanical seal
POSSIBLE SOLUTION
Check that the main disconnect switch
is in the "ON" position.
Check for voltage in the power supply
line.
Check that the protective devices upli-
ne and downline of the transformer of
the auxiliary circuit are undamaged.
Reset the triggered protective device
after eliminating the cause that trigge-
red it
Restore the connection of the display
or replace it.
Replace the control.
Restore the connection between the
display and the control.
Replace the display.
Correct the weight distribution of the
unit by adjusting the height of the an-
ti-vibration mounts.
If it is not possible to work on the
control of the pump, partially close the
shut-off device on the delivery side of
the unit until the nominal flow rate is
restored.
Check that the air valves are not shut
off by valves.
Vent the system.
Check that the high pressure switches
are working and, if necessary, replace
them.
The valve must be replaced.
Replace the valve and restore the
charge.
Pressurize the pump body 2 or 3 times
by closing and opening the delivery
valve so as to correctly bed in the seal.
