6.3.2 The resistance test of the flame regulator
WARNING
The glass element of the flame regulator and the
observing glass of the disc (see the figure) should be
cleaned when they get dirty. The flame regulator should
be replaced when it is damaged or cannot reach the
nominal value.
6.3.2.1 The flame regulator in the control device 1553
- Connect the ohmmeter to the flame regulator
- Darken the surrounding of the flame regulator. Put a
black insulation hose on it in order to darken it and
pull the edges.
- The resistance should go up to > 100 ohm in about 20
seconds.
- Light a match at approximately 1 cm distance from the
flame regulator. The resistance should be reduced to
approximately 300 Ohm at that time.
6.3.2.2 The flame regulator in the control device
1563/64
In assembled status
- Connect the voltmeter to the connections points
D6(+) and D7 (-) of the control device.
- Start the heating device.
- The voltage that will be measured should be 5 Volt.
The voltage should be reduced to < 1 Volt after about
15 …. 26 seconds.
In dismantled status
- Connect the flame regulator over a pre-resistance of
1 k-Ohm to 5 Volt.
- Connect the voltmeter parallel to the flame regulator.
- The voltage should be reduced to > 1 Volt when the
lens is darkened or the lamp (5 W) is shown.
