Display information and fault information how to set bypass mode
Display |
Meaning |
A06 | Sensor1 temperature under 0°C |
A08 | Sensor2 temperature under 0°C |
A54 | Load percentage greater than the user threshold set |
A61 | Replace battery |
A62 | Batteries missing or Battery Box missing / not connected |
A63 | Waiting for battery to charge |
It is worth sorting these as they usually don’t improve when left
Display |
Meaning |
F03 | incorrect auxiliary power supply |
F04 | Heatsink over temperature |
F05 | Temperature sensor 1 fault |
F07 | Temperature sensor 2 fault |
F11 | input relay fault |
F13 | Capacitor pre-charge failed |
F21 | Capacitor bank overvoltage |
F38 | Battery charger fault |
F40 | Inverter overvoltage |
F41 | Continuous output voltage |
F42 | Incorrect inverter voltage |
F43 | Inverter under voltage |
F50 | Overload: load > 103% |
F51 | Overload: load > 110% |
F52 | Overload: load > 150% |
F53 | Short Circuit |
F55 | Waiting for load reduction to return to inverter |
F60 | Battery Over Voltage |
Display |
Meaning |
C01 | Remote control 1 (Switch On/Off) |
C02 | Remote control 2 (Bypass Mode) |
C03 | Remote control 3 (Switch On/Off) |
C04 | Battery test in progress |
At this point the UPS has stopped being a UPS but may still provide power on bypass
