4. ALARMS AND TROUBLE SHOOTING
The UC protects the unit and the components from damaging in abnormal conditions. Each alarm is activated when the abnormal
running conditions require an immediate stop of the whole system or sub-system to prevent potential damages.
When an alarm occurs the proper alert icon will be turned on.
•
In case of Master/Slave or VPF function enabled it’s possible to have alert icon blinking with [07.00]’s value equal to
zero. In these cases, unit is enabled to run because the alert icon refers to function errors, not unit ones, but registers
[08.14] or [16.16] will report value greater than zero. Please refer to specific documentation for Master/Slave or VPF
function troubleshooting.
In case of alarm occurrence,
it’s possible to try an “Alarm Clear” through the [7.01] parameter in order to allow the unit restart.
Please notice that:
•
If alarm persist refer to
table in chapter “Alarm List: Overview” for possible solutions.
•
If alarm continue to occur after manual reset contact your local dealer.
