Chapter 2 Operation

Alarm Codes

Alarm LED Flash Sequence

While the MiniDySC is in the alarm state due to a non-fatal alarm, the amber

LED will flash the alarm code sequence at 1Hz where the number of flashes

equals the alarm code. There is a two-second delay, after which the code will

repeat if the error condition persists. This group of alarms are those that the user

can act to correct, such as an overload or input over-voltage.

Some alarms cannot be corrected by user action. These alarms may require service

by a qualified technician. For such alarms the amber LED will flash continuously

at a faster 6 Hz rate.

Inverter Run Time out

MiniDySC inverter had a total cumulative runtime of more than rated. No action is needed

Inverter Limit Cycle Timeout Power was re-applied more than once within a 58 second period. No action is needed

Overload

Inverter inhibited because load current exceeded maximum rating. Reduce the load

Static Switch Over -Temperature Static switch heatsink temperature was greater than maximum rating.

• Verify ambient temperature is within specification

• Check for dirty or obstructed air vents

• Check fan is operating (500VA and 750VA only)

DC Bus Over-Voltage 5 Positive or negative half of DC bus voltage exceeded maximum rating.

• Verify line voltage is within ratings.

• Verify proper MiniDySC application
