3.17 Main Menu - Application Functions - Group 22
This group contains parameters used for monitoring ADAP-KOOL applications.
22-00 External Interlock Delay
Range: Function:
0 s* [0 - 600 s] Only relevant if one of the digital inputs in par. 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.
3.17.1 22-2* No-Flow Detection
The ADAP-KOOL Drive 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 (No Flow Delay par. 22-24) before selected action takes place. Possible actions to select (par.
22-23): 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 ADAP-KOOL Drive 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
Carry out No Flow tuning before setting the PI controller parameters!
