Weekly timer
It is possible to make 28 different settings for one week in total which means up to four settings per
day on 7 days. In this mode, the memory locations have to be made in correct order so that further
free memory shows up. Initially you will see four selectable settings (W1-W4). W5 only shows up if all
four previous ones are used. The approach to enter settings is similar to the daily timer and only differs
by an additional option of the weekday.
6. PROBLEMS, CAUSES AND SOLUTIONS
In the case of tube failure, the electronic ballast switches the tube off so the board is
protected, and the malfunction is detected through our monitoring units.
Problem Cause Solution
Immediately after switching
on the device, the ground
fault circuit interrupter (GFCI)
trips.
The device has a power shortage and
is no longer operational.
It is possible water entered
into the product.
The power supply must be
interrupted and the system
has to be replaced. It has to be
subjected to a thorough check
by the manufacturer.
The device is switched on, but
the tube does not ignite.
No power supply.
Gas pressure drop through fine cracks
in the tube or damage of the pins on
the tube socket.
Are the connections of the
power supply properly
connected?
Check the tube and the socket
for its integrity and
abnormalities in the tube
socket.
The device is turned on and
the tube flashes briefly, but
does not ignite.
The tube is new.
The tube runs for more than
12,000 hours.
The electronic ballast is trying to
ignite the tube, but the process is
aborted because the gas pressure of
the tube is too low.
In case of a new tube it is a
manufacturing defect.
In older tubes (>12,000 hours) the gas
composition has changed, an ignition
is no longer possible.
Ignite the unit with a
replacement tube, the fault is
in the tube.
We will gladly replace this
tube free of charge
The tube life is exceeded, the
tube must be replaced.
