VSD safety monit.
Choice of safety monitoring of frequency converter. A digital inlet is used
for monitoring the frequency converter.
Capacity limit at night
Setting of maximum capacity limit during night operations. Can be used
to limit fan speed at night in order to limit the noise level.
Monitor Air flow
Choose whether monitoring is required of the condenser's air flow via an
intelligent error-detection method.
Monitoring requires the use of a Sc3 outer temperature sensor, which
must be fitted by the condenser's air inlet.
FDD setting
Set error-detection function
Tuning: The controller makes an adjustment to the condenser concerned.
Note that tuning should only be done when the condenser is operating
under normal operating conditions.
ON: Tuning is completed and monitoring has commenced.
OFF: Monitoring is cut out.
FDD sensitivity
Set the sensitivity of error-detection on the condenser’s air flow. Must only
be changed by trained staff.
