WATTrouter M - user manual
How to fit and setup the device
Page 73 from 79
Incorrect settings of some
items in the Other settings
tab
Check the settings in the Power offset field.
Also check the CombiWATT production limit
field, which should be low.
You cannot download firmware,
even if you try repeatedly
Incorrect or corrupted
*.scf file
Load only original firmware for the
WATTrouter M device.
Communication errors
Make sure that there are no problems with
the connection of the controller to PC, or in
the PC alone (viruses etc.).
Regulator failure/defect
Replace the regulator or take it to repair.
The built-in fan does not work
(does not spin) when triac
outputs are on
Fan is disconnected
Remove the regulator cover and make sure
that the fan is connected.
Fan does not work
Replace your fan with SUNON MagLEV
12VDC, 35x35x10mm ventilator, with
power rating of 0.5 W or 0.75 W or contact
your distributor to get spare part.
The sound of the fan changes
irregularly
This is normal
The speed of the fan is regulated in order to
provide optimal cooling.
Fan makes strange noises
The fan is defective
Replace your fan with SUNON MagLEV
12VDC, 35x35x10mm fan, with power rating
of 0.5 W or 0.75 W or contact your
distributor to get spare part.
Flashing red LED
The system detected error
status
Follow instructions in the LED statuses
chapter.
When the available surplus
energy is decreased, the
triac/SSR output with higher
priority is switched off earlier
than the relay output with lower
priority
This is normal
Relay outputs have always longer delay
when in the process of disconnecting. In
order to make sure that energy from the
power grid is not drawn unnecessarily, all
connected proportional outputs with higher
priority may be disconnected earlier than
the relay outputs with lower priority.
CombiWATT function runs even
if PV-plant produces power
This is normal
CombiWATT will be initiated even if during
the time specified in the CombiWATT delay
time field, no production is detected at any
phase wire, which may occur if the PV-plant
produces small amount of energy or if loads
with large power consumption operate for
long time and consume all available surplus
energy. If you want to eliminate this
behavior, increase the value in the
CombiWATT delay time field.
Solid state relay (SSR) does not
switch on
SSR is not connected
correctly
Check for proper terminal connection and
observe polarity of SSR control anodes.
Incompatible relay
Always use a SSR with zero cross switch and
minimum DC control voltage of 4VDC.
Regulator failure/defect
Replace the regulator or take it to repair.
SSR failure/defect
Replace the SSR.
Data in statistics don't
