87
Protection shutdown over-
current L1
A current that has been found on a conductor
is too high. An internal protective mechanism
has disconnected the device to protect it
against damage.
Poll the wiring on
the AC side (induc-
tance of a trans-
former).

Protection shutdown over-
current HW
Too much power has been fed into the grid.
Complete disconnection of the device.
Notify authorized
electrician / KACO
Service!

Protection shutdown HW
overtemperature
The device has been switched off because the
temperatures in the housing were too high.
Switch off AC+DC ->
Wait 5 minutes ->
Switch on AC+DC ->
if this is not success-
ful, contact the ser-
vice department

101
Temperature plausibility er-
ror
The individual temperatures in the device are
compared with one another. This fault occurs
if a certain limit value is exceeded.
Notify KACO Ser-
vice!
K
102
Plausibility fault efficiency
The degree of efficiency of the device must re-
main within certain limits.
Notify KACO Ser-
vice!
K
105
Relay plausibility error
Check the voltage measurement upstream of
and between the relays - the difference can be
a maximum of 24 V
Switch off the de-
vice entirely (switch
off AC + DC for min.
5 minutes), if the
fault occurs again,
there is a device
fault

107
Check surge protection de-
vice
Surge protection device (if present in the de-
vice) has tripped and must be replaced. AC, DC
& interfaces are monitored for triggered surge
protection. All 3 LEDs light up on the device.
Check surge protec-
tion in the device.
The surge protec-
tion module has a
corresponding func-
tion display. With a
red function display,
the surge protection
module must be
checked, and re-
placed if necessary.
The device feeds
back into the grid.
