Alarm and event messages
Load polarity
Description Detection of an error in the load polarity.
Corrective
action
Check the transformer connections. See section “7.9.- TRANSFORMER CONFIGURATION”
Disabled X harmonic
Description Harmonic X has been disabled due to resonance.
Corrective
action
The resonance detection function can be activated erroneously in installations with a very high volt-
age THD. Contact the TAS.
Annual maintenance
Description A year has passed since the last maintenance procedure was carried out and the maintenance meter
was reset.
Corrective
action
Perform the annual maintenance procedure and reset the maintenance meter. (see “10.- MAINTE-
NANCE”)
Fan maintenance
Description Fans have been operating for over 40,000 hours; they must be replaced and the maintenance meter
must be reset.
Corrective
action
Replace the fans and reset the maintenance meter. (see “10.- MAINTENANCE”)
Fan deterioration
Description Deterioration in the ventilation capacity of the system has been detected.
Corrective
action
Check that the fans are clean. Perform the periodic maintenance tasks. Replace the fans if this does
not solve the problem. (see “10.- MAINTENANCE”)
Mains voltage out of limits
Description Mains voltage below the minimum
Corrective
action
This alert may be associated with transients and noise in the power supply voltage, or with incorrect
mains frequency values. Check the configuration. Check the quality of the power supply voltage. If it
continues, contact the TAS.
Min temperature
Description Temperature below the minimum operating value
Corrective
action
Wait for the environmental conditions to meet the requirements. If the alarm continues, contact the
TAS.
Mains frequency limits
Description Main frequency out of the limits
Corrective
action
This alert may be associated with transients and noise in the power supply voltage, or with incorrect
mains frequency values. Check the configuration. Check the quality of the power supply voltage. If it
continues, contact the TAS.
Minimum current
Description Mains current below the programmed level.
Corrective
action
Check the configuration.
Maximum load
Description Filter working at full load
Corrective
action
No action is necessary.
Low power factor
Description
The power factor value measured is less than 0.7, which might indicate a connection error in the
measuring transformers, where the voltage phases do not correspond to the current phases.
