3.20 Main Menu - Application Functions - Group 22
This group contains parameters used for monitoring VLT HVAC Drive 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.
22-01 Power Filter Time
Range: Function:
0.50 s* [0.02 - 10.00 s]
3.20.1 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.
