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.
