exceeded. The cabinet has temporarily shut down to prevent
damage and will restart once the supply voltage decreases.
1, 2, 3, 4
Should be a one off; if continues:
- Line voltage / rural
- Voltage setting parameter
- Controller
Under-voltage protection.
The mains supply voltage has dropped below the minimum
allowable level. The cabinet has temporarily shut down to
prevent damage and will restart once the supply voltage
increases.
1, 2, 3, 4
Should be a one off; if continues:
- Power supply overloaded / multibox
- Line voltage / rural
- Voltage setting parameter
- Controller
High condensing temperature protection.
The system was operating at an elevated temperature and has
temporarily shut down to prevent damage. Extended operation
in this condition may result in ALARM 15, increased energy
consumption and a reduction in cabinet life. This alarm may be
caused by very high ambient temperature.
