ERROR MODES
D) OVERCURRENT ERROR
Appearing of an error may also be the result of rapid powering on
the load. It may also occur if the soft-start functionality is disabled
(parameter 34 set to 0) or as a result of the short circuit.
If parameter 37 is set to 1, the device will automatically try to turn on
again.
If described error has been caused by the rapid powering on the load,
then FIBARO Dimmer 2 will return to normal operation after reen-
abling.
After three unsuccessful automatic tries of turning on the load, Dim-
mer 2 will stay in OVERCURREnT error mode (module turned off). In
such situation, it is required to remove the failure (possible short cir-
cuit in the installation.) Otherwise, it is recommended to set the long
soft-start (parameter 34 set to 2).
E) OVERLOAD ERROR
Appearing of an error is a result of connecting receivers with too
much power consumption. In this case FIBARO Dimmer 2 will auto-
matically turn off the lighting.
It is required to reduce power consumption of connected load (e.g. by
reducing the number of receivers) and turn on the light source again
by the wall switch or a Z-Wave command.
F) VOLTAGE DROP ERROR
Appearing of an error in a 2-wire connection may be the result of
mains voltage drop or a too high brightness level of the light source.
If parameter 37 is set to 1, the device will automatically try to turn on
again.
Voltage drop error suggests that parameter 2 value should be re-
duced until disappearing of the failure. You can also recalibrate the
load using parameter 13.
After three unsuccessful automatic tries of turning on the load, Dim-
mer 2 will stay in VOLTAGE DROP error mode (module turned off).
G) HARDWARE FAIL ERROR
Appearing of an error may be a result of serious hardware failure of
the Dimmer 2. In this case the Dimmer 2 sets the maximum brightness
level and the LED visual indicator starts blinking in red. All external
actions (Z-Wave commands, pressing the switches, menu settings)
will be ignored.
We recommend disconnecting the device from the power supply
and contacting the customer service or to initiate the guarantee
procedure.
This error may also appear as a result of enabling the Dimmer 2
without load connected to the output in 3-wire connection. It is not a
dangerous situation. We recommend disabling the fuse, connecting
the load and enabling the fuse again.
