Alarms; Troubleshooting - Italtecnica CRONO SPY Manuel D'instructions

The trip time of the current overload safety device is inversely proportional to the entity of the overload in
progress; therefore a slight overload will lead to a more delayed trip time while a more significant
overload will accelerate the trip time. The parameter can be set from 0.5 to 12 A. On activation of the
device, if the Imax parameter is set at 0.5 A (factory setting), the display automatically shows the settings
page of the maximum current and no action is admitted until the absorption limit value is set.

ALARMS

immediately, simply press "reset".
following problems with the electrical connection between the motor and Crono Spy. If this alarm trips
frequently, arrange for the system to be checked by the installer.

TROUBLESHOOTING

The pump does not start
If an electric float is used, check operation.
If no electric float is used, check that the jumper is wired on the relative terminals.
Ensure correct connection between Crono Spy and the electric pump
The pump does not stop
The mechanical float may not close completely; ensure that no foreign bodies obstruct movement of the
float.
If installed, the electric float may not be operating correctly.
The check valve inside Crono Spy may be blocked in the open position; ensure correct valve movement
and remove any foreign bodies by means of compressed air if necessary.
The sensor reading the valve position is faulty; arrange for the device to be checked by the manufacturer.
Imax (optional): this optional parameter enables entry of the maximum
current absorbed by the electric pump in routine conditions, to enable
shutdown of the motor in the event of excessive absorption. The motor is
also shut down event if the current read during operation is below 0.5 A
following interruption of the connection between the motor and Cronospy.
No flow: this message is displayed when Crono Spy no longer detects transit
of water through the electric pump. This may be due to normal closure of
the mechanical float positioned in series with the device, or the lack of water
on intake to the pump. The error disappears after one minute and the display
returns to the main screen. To remove the error message from the display
Overload (optional): for versions equipped with current sensitivity control,
this alarm is displayed when electric pump absorption exceeds the
maximum set current as entered in the parameter Imax; this may occur
following intensive use of the electric pump, continuous restarts at close
intervals, problems with the motor windings, seizure of the pump rotor or
