Solution
No light for the
Power supply
indicator (L1, L2
&
L3 LED).
Is AC power
supply connected
to the
meter ?
Is the L1, L2, L3
and
N
connecting
correct ?
Maybe there is
Check switch or circuit-
breaker and fuse or thermal
cut-off.
Reinstall terminal screws on the
L1, L2, L3 and N. Make sure all
screws are fixed. Than there
should be a 230V 50Hz AC
voltage between the terminal
screws on the N and L1 or L2
or L3, when power supply is
input.
Please contact technical
support to replace this meter.
No light for
the
consumption
indicator (PULSE
& SOLED).
Is the
load
running
?
Is the
operating
power too
low ?
Only when load is running, this
LED will flash.
If the operating power is too
low, the spacing interval of the
flashes will take some more
time, this is why it seems like
the LED isn’t burning.
Please contact technical
support to replace this meter.
