Description
Check
1
Output
Overload!
Load is drawing too much
current (>16A)
Check the power rating of connected heaters, the maximum
rating is 3.7kW for each heater output.
2
Overheat!
The device is too hot
Check ventilation slots are not blocked and the unit
has sufficient space around it. Refer to clearances section.
3
No Signal!
Signal lost
from
harvi
device
Check harvi LED is blinking; if not, check sensors are securely
clamped around the cable and properly connected to the
terminals in the
harvi
Note:
harvi
will stop working if there is
no power in the cable being monitored, however
eddi
will show
this message only if there is no signal from
harvi
for more than
24hrs.
4
Grid Sensor
Error!
Grid Sensor incorrectly
installed
Check the sensor is securely installed on the correct cable and
is wired to the CT terminals with the correct polarity Refer to
the
Grid CT
section for details of correct installation.
5
Back-Feed
Voltage!
Unexpected voltage at
heater output
The heater output terminals must never be connected to a
supply voltage Check heater wiring.
6
Over
Voltage!
Supply voltage too high
The AC supply voltage must be less than 260V Check the AC
voltage at SUPPLY terminals.
7
Under
Voltage!
Supply voltage too low
The AC supply voltage must be more than 190V Check the AC
voltage at SUPPLY terminals.
8
Load Fault!
Load is faulty
Check the power rating of connected heaters, the maximum
rating is 3.7kW for each heater Output Isolate the unit from the
supply and check the resistant between L1 and N and between
L2 and N at the HEATER terminals; the resistance should be
between about 15
Ώ
and 350
Ώ
. Note: Around 18-20
Ώ
is
normal for an immersion heater.
