"Control mode”
BE indicates that the signal is present on terminal 2, and all other
signals = 0
If the FMS controls a flue gas damper, this opens. It is possible to switch
to "Setting”.
ZÜ indicates that pre-ventilation is finished and the ignition position relay
EZ 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 indicates that the burner is on (terminal 8=1), but the control release is
EG 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 ducts 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 acceptance key the existing curve is cleared and a new
curve can be entered.
EV indicates that although the mode selector switch is on "Setting”
it is nevertheless performing the pre-ventilation routine.
These is a signal on terminal 3.
_______________________________________________________________
If the selector switch is on "Setting” and there is a "signal on terminal 3”,
the FMS nevertheless maintains its control function.
The setting mode (display "EI”) is only activated when the pre-ventilation
is completed and there is a flame signal and control release. The FMS
can therefore only be programmed when the signal combination
corresponds either to the "AU” and/or "BE” modes, or when the signal
combination corresponds to the "Automatic” mode.
