Configuration
Reaction Time (1 to 20) This setting together with the next regulate
the sensitivity of speed control. These should be left at
the default settings and should only changed by a
Danfoss-trained technician.
Algorithm Interval (1 to 15) This setting together with the preceding one
regulate the sensitivity of speed control. These should
be left at the default settings and should only changed
by a Danfoss-trained technician.
Inverter max resets (0 to 10) The number of reset attempts, when proof is
not detected, before the variable speed drive will be
placed in override.
Inverter reset delay (0 to 600) The number of seconds that must elapse
between resets.
Inverter proof delay (0 to 600) The number of seconds that must elapse
after proof is not detected, before a reset attempt.
Monitor phase loss (List box: Yes, No) Whether or not phase loss will be
monitored.
Shutdown on phase loss (List box: Yes, No) Whether or not the unit is to be
shut down when its phase loss detector input is on.
Shutdown on smoke detect (List box: Yes, No) Whether or not the unit is to be
shut down when its smoke detector is on.
Shutdown on fire alarm (List box: Yes, No) Whether or not the unit is to be
shut down when a monitored fire alarm occurs.
