EV indicates that although the mode selector switch is on "Setting” it is nev-
ertheless performing the pre-ventilation routine. These is a signal on ter-
minal 3.
If the selector switch is on "Setting” and there is a "signal on terminal 3”,
nevertheless the FMS 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. Therefor the FMS can only be
programmed, when the signal combination corresponds either to the
"AU” and/or "BE” mode, or when the signal combination corresponds to
the "Automatic” mode.
ES indicates that although the mode selector switch is on "Setting”.
Iit's control function is working according to a calculated curve in the
RAM. The curve is calculated from a partial curve, which is already
entered. This mode is reached if the burner is switched off and is
restarted during a programming sequence. The programming can be
continued by operating a switch (change to "EI” mode”). Flame signal
and control release are present.
ST indicates that the FMS is set to "Fault”. The fault code can be called up in
switch position "Status”. In the switch position "load rating” the load rat-
ing at the time when the fault occurs, is displayed.
VO indicates that the FMS is in "Pre-ventilation” mode. There is a signal on
terminal 2 and a signal on terminal 3. Pre-ventilation routine is active.
HAND
or
HA
indicates that the FMS has been switched to manual mode whilst the
burner is running. In the selector switch position "Load rating” the load
can be adjusted by actuating the channel 1 switch. To quit manual mode,
actuate any switch but the channel 1 switch.
ext.Hand indicates that the FMS was switched to manual operation, but the load
was specified externally and not via the channel 1 key (that is, e.g. via
remote software or bus).
LE indicates that the output regulator of the FMS is deactivated and the fir-
ing rate is controlled by an external signal
