Step: Pump run times
Note
Step is repeated per pump
The parameter in this step will need to be set for each pump used in the application.
This step is only visible if pump control mode is set to "Service ratio duty assist" or "Service
ratio duty backup".
Run time pump 1
Sets the amount of time the pump has been in operation.
Setting
Default
Enter the run time of an existing pump to be used in this application. Leave as default of zero
hours if using a new pump that has never run.
The value entered here is written to parameter "Runtime relay x" (found in menu "Pump
control" (3.4.4.)), where 'x' refers to the relay assigned to the pump being configured here. If
any value has been previously set in "Runtime relay x", it will be displayed here, and any value
written by the wizard will supersede other values upon completion of the wizard.
Step: On/off setpoints
Note
Step is repeated per pump
The parameters in this step will need to be set for each pump used in the application.
Note
On/Off setpoints per application
The setpoints must be set correctly for the application:
• For a pump down application, all of the off setpoints must be less than all of the on
setpoints,
• For a pump up application, all of the on setpoints must be less than all of the off
setpoints.
