Application Guide
Parameter Descriptions
11.22.5.1 (ID 1704) Frost Protection
Location in the menu: P3.21.5.1
Use this parameter to enable the Frost Protection function. If the measured temperature of the pump goes below the set level and
the drive is in sleep state, the frost protection makes the pump start and operate at a constant frequency.
11.22.5.2 (ID 1705) Temperature Signal
Location in the menu: P3.21.5.2
Use this parameter to select the source of the temperature signal that is used for the Frost Protection function.
11.22.5.3 (ID 1706) Temperature Signal Minimum
Location in the menu: P3.21.5.3
Use this parameter to set the minimum value of the temperature signal. For example, a temperature signal range of 4...20 mA
agrees to the temperature of -50...200 °C.
11.22.5.4 (ID 1707) Temperature Signal Maximum
Location in the menu: P3.21.5.4
Use this parameter to set the maximum value of the temperature signal. For example, a temperature signal range of 4...20 mA
agrees to the temperature of -50...200 °C.
11.22.5.5 (ID 1708) Frost Protection Temperature Limit
Location in the menu: P3.21.5.5
Use this parameter to set the temperature limit at which the drive starts. If the temperature of the pump goes below this limit and
the drive is in the sleep state, the frost protection function starts the drive.
11.22.5.6 (ID 1710) Frost Protection Frequency
Location in the menu: P3.21.5.6
Use this parameter to set the frequency reference of the drive that is used when the frost protection function is activated.
11.22.5.7 (ID 1711) Frost Temperature Monitoring
Location in the menu: P3.21.5.7
This monitoring value shows the value of the temperature signal that is used for Frost Protection function.
11.22.6 Flow Switch
11.22.6.1 (ID 15590) Flow Switch
Location in the menu: P3.21.6.1
Use this parameter to select the digital input signal that is the feedback signal from the Flow Switch.
11.22.6.2 (ID 15585) Flow Switch Fault Delay
Location in the menu: P3.21.6.2
Use this parameter to set the time that the feedback signal from Flow Switch must stay inactive before the Flow Switch fault occurs.
11.22.6.3 (ID 15586) Flow Switch Bypass at Start
Location in the menu: P3.21.6.3
Use this parameter to set the time after which the Flow Switch supervision becomes active at the start-up of the drive.
11.22.6.4 (ID 15587) Flow Switch Minimum Frequency
Location in the menu: P3.21.6.4
Use this parameter to set the output frequency level below which the Flow Switch supervision is disabled.
