This in turn minimizes the reactive power transmitted back to input power cables. This fault is set when the PFC circuit exceeds a peak current limit when driving compressor. System will shut down and VFD will reset, if demand persists, system will attempt to resume normal operation. After 2 occurrences within 10 minutes, code 81-53 is set and system is locked out for 4 hours. A power cycle will clear malfunction lockout timer. Continued malfunctions indicate high current situation. This is likely due to VFD or compressor damage. Measure reactor(s) resistance. As reactor charges the resistance will be reduced to 0. If measurement is open, replace reactor. Otherwise replace VFD.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<p class=\"has-small-font-size wp-block-paragraph\"><em>P\u00e1ginas de soluci\u00f3n de problemas
