s 10
Delay time for HB alarm activation
The value must be greater than the power output cycle time.

5.2.1.7. HB alarm threshold
Acronym App / GF_eXpress menu Attribute Retentive U.M. Default
Description
A.Hb
Alarms  HB Alarm
R/W
■
A 0.0
Current threshold for the HB alarm: below this measured current threshold, for a period greater than
Hb.t, the alarm will trigger (with Hb.F = 0)

5.2.1.8. Current Hb.tr alarm threshold
Acronym App / GF_eXpress menu Attribute Retentive U.M. Default
Description
Hb.tr
Expert  Status  Diagnostics
R - A -
HB alarm threshold as function of power on load
The Hb.tr threshold value of the HB alarm is calculated in two different ways, depending on the
chosen operating mode:
if FCT, BF, HSC mode: Hb.tr = A.Hb
if PA mode: Hb.tr = A.Hb * sqrt(Ou.P)
5.2.1.9. Calibration status
Acronym App / GF_eXpress menu Attribute Retentive U.M. Default
Description
STATUS
Controls R/W
■
- -
Device Status STATUS indicates whether the device is in calibration/current threshold learning mode.
NOTE: The status is stored in the retentive memory, so if the device is put in calibration mode and
then turned off, it will still be in learning mode at the next start.
bit Meaning
7 HB alarm threshold calibration in progress
