Level analog enable If enabled the analog input will be used in conjunction with the digital inputs for alarms.
Max level sensor range The maximum range of the analog level sensor used.
Setpoint stop level Target Setpoint stop level to be reached by the system.
Wakeup level step The analog level step from the setpoint stop level before the system will wake from sleep and start the
duty pump. For example, in a level empty application, if the setpoint stop level = 0.5m and wakeup level
step = 0.2m, the duty pump will start at 0.5m + 0.2m = 0.7m.
Standby start level step The analog level steps from the wakeup level step at which the standby pumps start. Following on from
the above example, if the standby start level step = 0.5m, the 1st standby pump will start at 0.5m + 0.2m
+ 0.5m = 1.2m. The 2nd standby pump will start after another 0.5m step, therefore at 1.7m, and so on for
any additional standby pumps.
Low level threshold When the analog goes below this threshold for 3 seconds the Low level protection will be activated.
High level threshold When the analog goes above this threshold for 3 seconds the High level protection will be activated.
Pressure analog enable If enabled the analog input will be used as well as the digital inputs for the pressure control and alarms.
Max pressure sensor
range
The maximum range of the analog pressure sensor used.
Setpoint Target Setpoint to be reached by the system.
Wakeup pressure drop The analog pressure step below the setpoint before the system will wake from sleep and start the duty
pump. For example, if the setpoint = 500kPa and the wakeup pressure drop = 50kPa, the duty pump will
start at 500kPa - 50kPa = 450kPa.
DOL Standby start
pressure step
The analog pressure steps below the Wakeup pressure drop at which the standby pumps start in the DOL
Control output type. This setting is not used in the VSD Control output type.
Low pressure threshold While a pump is running above the No demand speed, if the analog goes below this threshold for 30
seconds the Low pressure protection will be activated.
High pressure threshold When the analog goes above this threshold for 3 seconds the High pressure protection will be activated.
Temperature analog
enable
If enabled the analog input will be used in conjunction with the digital inputs for the temperature control
and alarms.
Max temperature
sensor range
The maximum range of the analog level sensor used.
Setpoint Target Setpoint to be reached by the system.
Wakeup temperature
step
The analog temperature step from the Setpoint before the system will wake from sleep and start the duty
pump.
Standby start temp step The analog temperature steps from the Wakeup temperature step at which the standby pumps start.
Low temperature
threshold
When the analog goes below this threshold for 3 seconds the Low temperature protection will be
activated.
High temperature
threshold
When the analog goes above this threshold for 3 seconds the High temperature protection will be
activated.
