UVD control
A voltage supply of 24 V DC is required to operate the
UV sensor for continuous operation UVD 1.
The 0 – 20 mA current output can be used to display
the flame signal. The cable to the control room must be
screened. The 0 – 20 mA current output is not required
for normal operation.
Depending on Parameter 79, the following connection
diagrams apply, see also page 73 (Pilot burner).
