(*) in pressure boosting mode (not KIWA) the alarm could be generated also by a float/level probe immersed in the pump from which the pumps
are drawing.
(**) in KIWA pressure boosting mode the alarm is not self-resetting and must be reset manually.

- JR: Relay/remote control switch stuck alarm

This error appears if the pump remote control switches have malfunctions. If this alarm occurs, check the wiring. If defects are found, the panel
must be repaired.

- NC: Pump Disconnected

This error appears if the E.Box panel does not "feel" current towards a pump. This error also appears if input KK (motor thermal protection)
opens.
The alarm is specific for the pump. For each pump the alarm allows a series of restart attempts with a variable pause time between one start
and the next which is increased by 1 minute for the first 60 minutes (1-2-3 min.... 60 min.), after which there will be one attempt every hour.

- BL: Dry running protection/alarm

The dry running protection/alarm is activated in a pressure boosting situation when an analog pressure sensor is connected, while in other
operating modes it is necessary to set the parameter SO at a value other than "OFF".
This protection can be activated by setting the parameter TB at a value other than zero.
The protection intervenes:
When the pressure falls to a value lower than the parameter MP (default 0.45bar) for a time equal to the parameter TB, the alarm is
•
activated with stopping of the pump and lighting of the led.
If the dry running factor for one of the pumps falls below this value during operation. For further information on the setting of SO, see
•
paragraphs 9.4.4 and 9.4.5.
After 1 minute there will be 1 reset attempt for maximum 30 seconds. If this attempt succeeds the alarm is reset, otherwise the pump will remain
in blocked status.
The dry running protection/alarm is not activated if the electropumps are started manually.
To solve the problem, check the hydraulic part of the plant. Check that everything is in order. Check also the pressure sensor and ensure the
pressure reading is regular.

- LK: Protection against too frequent starts

This error appears when the system needs more than 8 starts per pump per minute; this normally occurs when there are leaks in the system or
the expansion vessel is deflated.
The protection against rapid starts allows each pump a maximum number of 8 starts per minute.
The protection does not intervene if the number of starts per minute is less than 8.
To solve the problem, check whether there are any leaks and check the expansion vessel if present.

- OC: Current overload protection/alarm (overload protection)

This alarm appears in the event of a current overload on the pumps. The alarm is specific for the pump.
For each pump the current overload alarm allows 6 auto-reset attempts, every 10 minutes, in the space of 24 working hours. At the seventh
attempt the panel no longer makes auto-resets, unless after manual reset by the user. To solve this problem, check the pumps, the wiring, and
ensure the rated current of the pumps is set correctly. This error may be generated by a blocked pump.

- RI: RI alarms

These errors come from input R. The panel behaviour is different depending on the operating mode. The solution of the problem always
consists of checking the signal arriving from the input R.
