TYPE
SOLUTION
E018
Mains frequency too low
•
Make sure that the mains frequency is within the range allowed by
local legislation.
•
If the mains frequency is outside the allowed range because of the
conditions of the local grid, contact the electricity provider to ask for
their approval to change the operating limits.
•
If the mains frequency is within the allowed range, but the alarm
persists, contact our technical support service.
E019
Disconnection from the
grid controlled by the elec-
tricity provider.
•
Interface intervention required by the electricity provider .
E020
The direct current going
into the grid has a value
higher than the allowed
threshold.
•
Make sure that there is direct current going into the grid.
•
If the direct current going into the grid is outside the allowed range
because of the conditions of the local grid, contact the electricity
provider to ask for their approval to change the operating limits.
•
If the direct current going into the grid is within the allowed range,
but the alarm persists, contact our technical support service.
E021
The direct current going
into the grid has a value
higher than the maximum
instantaneous threshold
allowed.
•
Make sure that there is direct current going into the grid.
•
If the direct current going into the grid is outside the allowed range
because of the conditions of the local grid, contact the electricity
provider to ask for their approval to change the operating limits.
