Installation
The pin assignment of the connector is shown in
the wiring diagram.
The output signal 0(4)-20mA for flame intensity is
not separated by the supply voltage, so the sig-
nal refers to the operating voltage measures. If
this should lead to problems, a corresponding
isolating transformer can be provided upon re-

CAUTION: In order to guarantee a proper operation the compact
flame controller must be tested several times at all conditions. The
burner has to be started and stopped several times (the flame relay

must always interrupt reliably with no flame on). Carry out these tests
