ALARM DESCRIPTION
ERROR
PHASE ERROR
The three-phase VSP on switch-on runs a control on the correct cyclic sequence of all the
phases, if by chance an incorrect cyclic sequence was carried out, the VSP goes to alarm
mode, indicating “PHASE ERROR” and inhibiting each function of the VSP. In this condition
the pump is blocked, at the same time the ALARM OUTPUT relay activates, which can gen-
erate an external acoustic and visual signal.
ERROR
INV ERROR
If the VSP is ON, that is, the operation of the electric pump is enabled in any work mode
and an error occurs from the hardware part of the inverter power module, the VSP goes to
alarm mode. In this condition the pump is blocked, at the same time the ALARM OUTPUT
relay activates, which can generate an external acoustic and visual signal.
ERROR
LCD ERROR
If the VSP is found in any work mode and an error occurs on the display board or it does
not respond, the VSP goes to alarm mode. In this condition the pump is blocked, at the
same time the ALARM OUTPUT relay activates, which can generate an external acoustic
and visual signal.
ERROR
NO_COM
If the VSP is found in any work mode and there is no communication between the interface
board or and the power board, the VSP goes to alarm mode. In this condition the pump
is blocked, at the same time the ALARM OUTPUT relay activates, which can generate an
external acoustic and visual signal.
ERROR
NO.POW>OFF
If the VSP is found in any work mode and there is no voltage inbound during the shut-
down phase, the VSP goes to alarm mode. In this condition the pump is blocked, at the
same time the ALARM OUTPUT relay activates, which can generate an external acoustic
and visual signal.
ERROR
PFC.COM.ERR
If the VSP is found in any work mode and there is no communication between the power
logic and the PFC logic, the VSP goes to alarm mode. In this condition the pump is blocked,
at the same time the ALARM OUTPUT relay activates, which can generate an external
acoustic and visual signal.
ERROR
PFC.INV.ERR
If the VSP is found in any work mode and an error occurs on the hardware part of the PFC
module, the VSP goes to alarm mode. In this condition the pump is blocked, at the same
time the ALARM OUTPUT relay activates, which can generate an external acoustic and
visual signal.
ERROR
PFC.VDC.HIGH
If the VSP is found in any work mode and the voltage of the “Bus DC Link” is too high,
the VSP goes in alarm mode. In this condition the pump is blocked, at the same time the
ALARM OUTPUT relay activates, which can generate an external acoustic and visual signal.
ERROR
PFC.VDC.DIF
If the VSP is found in any work mode and the voltage of the “Bus DC Link” is “too” dierent
from the voltage of the “Bus DC PFC”, the VSP goes in alarm mode. In this condition the
pump is blocked, at the same time the ALARM OUTPUT relay activates, which can generate
an external acoustic and visual signal.
