Main Menu - Application Functions - TR200 - Group 22
This group contains parameters used for monitoring TR200 applications.
22-00 External Interlock Delay
Range: Function:
0 s* [0 - 600 s] Only relevant if one of the digital inputs in parameter group 5-1* has
been programmed for
External Interlock [7]. The External Interlock Timer
will introduce a delay after the signal has been removed from the digital
input programmed for External Interlock, before reaction takes place.
22-2* No-Flow Detection
The frequency converter includes functions for detecting if the load conditions in the system allow the motor to
be stopped:
*Low Power Detection
*Low Speed Detection
One of these two signals must be active for a set time (par.22-24
No-Flow Delay) before selected action takes
place. Possible actions to select (par.22-23
No-Flow Function): No action, Warning, Alarm, Sleep Mode.
No Flow Detection:
This function is used for detecting a no flow situation in pump systems where all valves can be closed. Can be
used both when controlled by the integrated PI controller in the frequency converter or an external PI controller.
Actual configuration must be programmed in par.1-00
Configuration Mode.
Configuration mode for
- Integrated PI Controller: Closed Loop
- External PI Controller: Open Loop
NOTICE
Carry out No Flow tuning before setting the PI controller parameters!
