BE indicates that the signal is present on terminal 2, and all other signals = 0
If the FMS controls a flue gas damper, it opens. It is possible to switch to
"Setting”.
ZÜ
EZ
indicates that pre-ventilation is finished and the ignition position relay
pulls on. The FMS is in the ignition position, but the flame signal is
absent. Switching to "Setting” merely causes the mode display to switch
to EZ. Programming is not possible in this mode.
GL
EG
indicates that the burner is on (terminal 8=1), but the control release is
absent (terminal 4=0). The FMS therefore remains in base load position.
Switching to "Setting” merely causes the mode display to switch to EG.
Programming is not possible in this mode.
NA indicates that the FMS is in post-ventilation mode.
All signals = 0
All air channels open. When the configured time has elapsed, the FMS
changes to "AU” mode.
AU indicates that the FMS is "OFF”. All control elements closed.
Selector switch on "Automatic”, all signals = 0
EI indicates that the mode selector switch is on "Setting”. Single points can
now be altered or new curves can be entered.
SL indicates that the mode selector switch is set to "Clear memory”. By
pressing the "Enter" key the existing curve is cleared and a new curve
can be entered.
