QRA73
The flame sensor QRA73 (UV cell) is connected to input X10-02:2-6 using
plug AGM23.
The flame sensor QRA73 is suitable for continuous operation. The combustion
manager tests the flame sensor in cycles in operating position (Phase 60) by simu-
lating a flame failure. The voltage at output X10-02:2 is increased 14 V to 21 V for
0.5 seconds. The signal voltage at the flame sensor therefore drops to 0 V
and the combustion manager receives the expected Off signal at input X10-02:6.
If the combustion manager is installed in a control panel, the connection must be
divided into 2 lines after the AGM23 plug and routed separately (max 100 m):
Supply line: Core 1, 2 and PE (L / N / PE),
Signal line (screened): Core 3, 4 and 5 (POWER QRI / N / QRI).
