ALARMS
If the VSP goes to alarm mode, the fountain leds turn ashing red. The ALARM signalling indicator light switches on and
on the alphanumerical part the name and type of alarm appears, according to the following:
ALARM DESCRIPTION
ERROR
EXT ALARM
If the VSP is ON, that is, the operation of the electric pump is enabled and "EXT ALARM"
closes with a clean contact NO, the panel goes to external alarm "EXT ALARM".
In this condition the VSP is blocked, at the same time the EXT ALARM relay is activated,
which can generate an external acoustic and visual signal. Typical example of use can be
signalled by alarm oat to signal the lack of water.
SENSOR PRES
SHORTCIRCUIT
If the VSP is ON, that is, the operation of the electric pump is enabled in any work mode and
a short circuit occurs or there is excess absorption on the pressure transducer, the VSP goes
to a “SHORT CIRCUIT” alarm. 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.
SENSOR PRES
OPENCIRCUIT
If the VSP is ON, that is, the operation of the electric pump is enabled in any work mode
and the connection is lost towards the pressure transducer or the transducer itself, the VSP
goes to a “CIRCUIT OPEN” alarm. 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
DRY RUN
If the VSP is ON, that is, the operation of the electric pump is enabled in any work mode
and the cosφ (read)<cosφ (min set ) or IN1 is enabled to work with an external minimum
ow sensor (see
BASIC CONFIG
T DRY 10
) without water intake, the VSP goes to DRY RUN alarm.
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
MAX CURRENT
If the VSP is ON, that is, the operation of the electric pump is enabled in any work mode
and the Current (read) > Max current (set), the VSP goes to “MAX CURRENT” alarm. 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
MAX VOLTAGE
If the VSP is ON, that is, the operation of the electric pump is enabled in any work mode
and the voltage (read)>voltage (maximum default setting), the VSP goes to alarm due to
“MAX VOLTAGE”. 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
MIN VOLTAGE
If the VSP is ON, that is, the operation of the electric pump is enabled in any work mode
and the voltage (read)<voltage (minimum default setting), the VSP goes to “MIN VOLTAGE”
alarm. 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.
