DESCRIPTION OF PARAMETER
AUTOMATIC RESET FOR DRY RUN
TIME 4
Fourth reset attempt counting from the previous reset attempt
(default: 30 minutes).
CYCLIC RESET FOR DRY RUN
Setting the N value stops automatic restarts after the fourth
attempt, while setting the S value after the fourth attempt resumes
the restart cycle starting from the fourth time that is set to an
infinite time.
The panel's dry run protection system restarts based on the pro-
gramming time settings, and resets the restart cycle whenever the
system detects the presence of water for more than 10 seconds.
ANALOG SIGNAL ACTIVATION
This parameter allows the input to be enabled with analog signal.
(With analogue signal enabled, if sensor C and MAX fails, it func-
tions as emergency stop and G/P1 as emergency start of pumps).
ANALOG SIGNAL TYPE
This parameter allows the type of panel input analog signal to
be selected
2-wire active sensor:
0-10V: Terminal "A/B" = signal; Terminal "-" = negative; 4-20 mA:
Terminal "+" = positive; Terminal "A/B" = signal;
3-wire passive sensor:
0-10V: Terminal "+" = positive; Terminal "A/B" = signal; Terminal
"-" = negative;
4-20 mA: Terminal "+" = positive; Terminal "A/B" = signal; Terminal
"-" = negative;
ANALOG SIGNAL UNIT OF MEASUREMENT
This parameter allows the unit of measure of the panel input
analog signal to be selected.
By selecting "bar", the panel works in PRESSURIZATION mode:
the motors will be enabled when the analogue signal decreases
compared to set point value (set point higher than start threshold).
EMPYTING OR FILLING ANALOG SIGNAL
Visible if "PRESSURIZATION" is not activated.
This parameter allows the operating logic of the analogue signal
to be selected if "none", "cm", "m" have been selected as unit of
measurement.
In FILLING mode, the motors will be enabled when the analogue
signal decreases compared to set point value (set point higher
than start threshold).
In EMPTYING mode, the motors will be enabled when the
analogue signal increases compared to set point value (set point
lower than start threshold).
ANALOG SIGNAL FULL SCALE
Visible if "ANALOG SIGNAL" is activated.
This parameter allows the full scale value of the analog sensor
used to be selected.
SET POINT
Visible if "ANALOG SIGNAL" is activated.
This parameter allows the set point to be maintained on the
system to be set.
The maximum settable value depends on the "ANALOG SIGNAL
FULL SCALE VALUE" set in the previous parameter.
START THRESHOLD M1 – M4
Visible if "ANALOG SIGNAL" is activated.
This parameter allows the first motor restart value to be set as the
analog signal decreases.
ALARM LEVEL THRESHOLD
Visible if "ANALOG SIGNAL" is activated.
This parameter allows the alarm value to be set as the analog
signal increases.
FILLING OR EMPTYING LEVEL PROBES
This parameter enables selection of whether the C-MIN-MAX
probe input is used in emptying or filling mode.
In FILLING mode, the input is used to enable the system when
water is not present. The C-MIN-MAX input must be open to
enable the system. If a float-type on/off control is used, use C
and MAX input.
In EMPTYING mode, the input is used to enable the system
when water is present. The C-MIN-MAX input must be closed
to enable the system. If a float-type on/off control is used, use C
and MAX input.
NB: If no minimum level control is used, jumper C and MAX input.
VALUE
DESCRIPTION OF PARAMETER
PROBE SENSITIVITY
This parameter allows the probe sensitivity level to be adjusted.
1 - 240 Min
FLOAT START/STOP FUNCTION ENABLE (self-holding)
This parameter allows active pumps to be deactivated only on
opening of the contact C and MAX (min./stop float).
This function is only available with pump rotation enabled and is
only used for emptying systems.
Y/N
MINIMUM LEVEL ALARM ACTIVATION
This parameter allows the cumulative alarm output to be removed
for minimum level.
EXPANSION TYPE
This parameter allows any added expansion to be removed.
0 = no expansion applied
Y/N
1 = PRO6DO expansion (6 digital outputs)
2 = PROSL expansion (lever probes for motor start)
3 = PROSL expansion (water seepage probes into oil chamber)
4 = PROSL expansion (water seepage probes into oil chamber
and stop motor)
MODBUS ADDRESS
MAXIMUM NUMBER OF IGNITIONS PER HOUR M1 - M4
0 = 0-10 V
This parameter allows you to set the maximum number of engine
1 = 4-20 mA
starts in an hour beyond which the alarm is triggered.
If set to 0, control is not active
ENGINE STOP FOR MAXIMUM IGNITION NUMBER ALARM
This parameter allows the engine to be stopped if the alarm for
the maximum number of starts per hour is triggered.
NUMBER IGNITIONS PER HOUR M1 - M4
"cm"/"m"
Only display of number of starts.
"bar"
NETWORK REENTRY DELAY
"NONE"
This parameter allows a fixed time from grid return to be activated
before turning on the pumps if controls are active.
