SENSOR PRES
SHORTCIRCUIT
If the control panel is in the ON state, i.e the pumps are enabled in MODE 5 PRESSURISATION
only, and there is a short circuit or the pressure transducer absorbs too much current, the
control panel enters the “SHORTCIRCUIT” alarm state.
In this state, the pumps are stopped and at the same time the EXT ALARM relay is activated to
generate an external acoustic and visual alarm.
SENSOR PRES
OPENCIRCUIT
If the control panel is in the ON state, i.e the pumps are enabled in MODE 5 PRESSURISA-
TION only, and the connection to the pressure transducer is lost, the control panel enters the
“OPENCIRCUIT” alarm state.
In this state, the pumps are stopped and at the same time the EXT ALARM relay is activated to
generate an external acoustic and visual alarm.
PUMP X
DRY RUN
If the control panel is in the ON state, i.e the pumps are enabled in any operating mode, and
one of the following control logic modes has been selected:
– DRY LOGIC=COS (default) and cosφ (read)<cosφ (set min)
or
– DRY LOGIC=CURR and CURR (read current)>CURR MIN (set minimum current)
The control panel enters the “DRY RUN” alarm state, the pumps are stopped and at the same
time the EXT ALARM relay is activated to generate an external acoustic and visual alarm.
PUMP X
MAX CURRENT
If the control panel is in the ON state, i.e the pumps are enabled in any operating mode, and
Current (read) > Current max (set), the control panel enters the “MAX CURRENT” alarm state.
In this state, the pumps are stopped and at the same time the EXT ALARM relay is activated to
generate an external acoustic and visual alarm.
PUMP X
CURRENT ERROR
If the control panel is in the ON state, i.e the pumps are enabled in any operating mode, and
the current read is less than 0.1 A for longer than 60 seconds, the control panel enters the
“CURRENT ERROR” alarm state. In this state, the pumps are stopped and at the same time the
EXT ALARM relay is activated to generate an external acoustic and visual alarm.
PUMP X
MAX VOLTAGE
If the control panel is in the ON state, i.e the pumps are enabled in any operating mode, and
Voltage (read) > Voltage max (set maximum), the control panel enters the “MAX VOLTAGE”
alarm state. In this state, the pumps are stopped and at the same time the EXT ALARM relay
is activated to generate an external acoustic and visual alarm.
PUMP X
MIN VOLTAGE
If the control panel is in the ON state, i.e the pumps are enabled in any operating mode, and
Voltage (read) < Voltage max (set minimum), the control panel enters the “MIN VOLTAGE”
alarm state. In this state, the pumps are stopped and at the same time the EXT ALARM relay
is activated to generate an external acoustic and visual alarm.
PUMP X
MOT.PR.WAIT
If the control panel is in the ON state, i.e the pumps are enabled in any operating mode, and
the thermal cut-out built into the motor opens the NO voltage-free contact up to ve times,
the control panel enters the self-resetting “MOT. PR. WAIT” alarm state.
In this state, the pumps are stopped and at the same time the EXT ALARM relay is activated to
generate an external acoustic and visual alarm.
