ATTENTION!
Defect due to improper handling!
Improper handling may cause a short circuit or
damages to the product.
– The mounted ionisation flame monitor is a
safety device. In case of damage, return the
ionisation flame monitor to the manufacturer.
With the aid of test diode A10Z2, it is possible to simulate the flame
signal.

1.
Switch off the power (after recommissioning).
2.
Open the red terminal (1) of the test diode by pressing
button (2).
3.
Apply the red terminal (1) of the test diode to the flame rod (3).
4.
Release key (2) in order to clamp the red terminal.
5.
Release the voltage to the ionisation flame monitor.
6.
Bring the yellow plug (4) of the test diode briefly into contact
with the outer tube (5).
7.
After contact with the test diode, a direct voltage of
90
– 110 V DC must be measurable at the cores/terminals of
the flame signal output.
In parallel, the LED (Fig. 17, 1) in the igniter head must light
up.
8.
If no flame signal is produced, check the following:
– Is mains voltage present at core/terminal 1 – 2?
– Is the polarity of the test diode correct?
– Are ceramic insulators damp, soiled or broken?
If so, clean or exchange these or if necessary replace the
ionisation flame monitor.
– Connect the flame rod to the power head.
REMARK!
In case of function problems, turn to the chapter
“Troubleshooting”.
