7.4.4 Alarms and errors visualization
Alarms
If an alarm occurs, the Numeric display [6] shows the alarm code alternatively to the current Main
Visualization as follows (Examples of visualizations):
A01 3.56 (Ex. BAR)
A02 285 (Ex. 10xRPM)
…
The A01..A0x error code, indicate the type of alarm detected by the circulator.
For more details about the Alarm codes detection and management, see par.7.6.
Errors
If a failure occurs, the Numeric display [6] shows a permanently Error code as follows:
E01
E02
…
The E01..E0x error code, indicate the type of error detected by the circulator.
For more details about the Error codes detection and management, see par.7.6.
7.5 Software parameters
Introduction
The parameters are applicable for all Drives with the following exceptions:
If a setting is transferred automatically on all drives within one system, this is marked with the
symbol (Global)
If a parameter is read-only, this is marked with the symbol (Read-only)
7.5.1 Status Parameters
P01. Required Value
This parameter shows the SOURCE and the VALUE of current required value.
Visualization cycles between SOURCE and VALUE every 3 seconds.
SOURCES:
SP (SP): internal required value Setpoint related to the control mode selected.
VL (UL): external required value speed Setpoint related to 0-10V input.
VALUE, can represent a Speed or a Head, dependent from selected control mode.
In case of Head, the unit of measure is defined by parameter P41.
P02. Effective Required Value
This parameter is effective only if the control mode is MSE or MSY.
P02 shows the current required value that is calculated based on parameters P58 and P59.
(See paragraph 10.3, for detailed information about P02 calculation).
P03. Regulation Restart Value [0÷100]
This parameter defines (default value 100), in percentage (0-100%) of the required value (P01),
the start value after pump stops.
If the REQUIRED VALUE is met and there is no more consumption, then the pump stops. The
pump starts again when the pressure drops below P03.
This parameter is effective when:
Different from 100% (100%=off), and
Control Mode is HCS, MSE or MSY
P04. Auto-start [OFF-ON]
If P04 = ON (default value ON), then the drive starts automatically (in case of demand) following
a power disconnection.
