Checking the ionisation current

A

Adaptor cable (available as acces-
sory)

1. 

Connect the test equipment accord-
ing to the diagram.

2. 

Set the upper heating output (see
page 18).

3. 

Ionisation current when the flame is
first established: Min. 4 µA
If ionisation current < 4 µA: Check the
electrode gap (see page 26).

4. 

Switch off the control unit ON/OFF
switch.
Operation with the upper rated heat-
ing output is terminated.

5. 

Record the actual value in the
"Reports" table.
