WATTrouter ECO - user manual
There are suspicious waveforms
shown in chart "Input checking
oscilloscope"
Positive measured power value
(production) differs too much
from the value on the inverter
display
Low tariff signal is missing
FB input does not work
The TEST button cannot be used
to switch on some of the
connected loads
How to fit and setup the device
Incorrect current
orientation settings
Regulator or current
sensing module defect
This is normal
There is connected some
load, which decreases this
value.
Inverter shows
approximate values, or
the status is not stable
Incorrect phase sequence
or incorrect current
orientation settings
Low tariff signal is not
connected
Low tariff signal is not
active
Regulator failure/defect
Output with open
collector is connected in
reverse polarity
Signal coming from the
output is an unsupported
impulse signal
Regulator failure/defect
The relevant load is not
connected or it is
connected incorrectly
according to chapter Setting up main
function and check with Input checking
oscilloscope.
Make sure that for all ILx inputs the
"Current orientation" field is correctly set.
Perform the settings according to chapter
Make sure that for all ILx inputs the
"Current orientation" field is correctly set.
Perform the settings according to chapter.
Replace the regulator and/or current
sensing module or take them to repair.
During normal operation there may be
shown even "exotic" waveforms. Be sure
this is the real current flowing through the
phase wire, a superposition of currents
flowing through the connected appliances
which are not sinusoidal or their power
factor varies from one.
No defect
No defect
Follow the steps specified in the previous
item.
Connect the low tariff signal to LT terminal.
You must connect the signal through an
auxiliary relay as specified in this manual.
Wait until the signal is active, or manually
test the auxiliary relay by switching it on
(some relays offer this option).
Replace the regulator or take it to repair.
Observe polarity of the device output
(energy meter, inverter).
Use only device with impulse output whose
signal carries information about the
measured energy and has a minimum
impulse width of 1 ms. Signal parameters
are described in chapter Technical
specifications.
Replace the regulator or take it to repair.
Check the connection of the relevant load
and switch on the corresponding circuit
breaker or fuse switch.
