GRAUPNER mz-24 Pro Programming Manual page 105

The setting programmed under MODE always refers
to the channel set in the line OUTPUT CH.
The default factory setting for all servos is HOLD.
For each selected OUTPUT CH (receiver servo chan-
nel), choose between the following:
• FAI-SAFE (Fail Safe)
In the event of a malfunction, a delay (as set in the
DELAY line) will occur, and the corresponding ser-
vo will move into the position displayed (in µs) in
the POSITION line. The servo will remain in this
position for the duration of the malfunction.
• HOLD
In the event of a malfunction, the servo remains in
the last servo position successfully received.
• OFF
In the event of a malfunction, the receiver stops
transmitting (buffered) control pulses for the rel-
evant servo output and the receiver switches the
pulse line off.
Notice
Analogue servos and many digital servos no
longer experience resistance to the ongoing
control pressure after control pulses stop and
are moved out of their position at greater or lesser
speed.
F.S.POS (Fail-Safe Position)
For each OUTPUT CH (receiver servo connection), set
the fail safe position for the servo to assume in a mal-
function in the F.S.POS line by using the
buttons.
The setting is made in 10-μs increments, as shown
below:

FAIL SAFE ALL : NO
POSITION
Default factory setting: 1500 μs (servo center).
Attention
In all three modes OFF, HOLD and FAI-SAFE (fail
safe), the function F.S.POS is particularly import-
ant when waiting for a valid signal after turning on
the receiver because the servo automatically moves into
the fail safe positions set in the POSITION line. This pre-
vents unwanted or incorrect actions to occur whenever
the receiver is accidentally turned on while the transmit-
ter is off. In normal model operation, during a malfunc-
tion the corresponding servo acts according to the
MODE setting.
DELAY
Set the time delay between when the signal is inter-
rupted and when the servos move to their set posi-
tions. This setting is adopted by all the channels and
only affects the servos programmed for FAI-SAFE (fail
safe) mode.
Default factory setting: 0.75 s.

FAIL SAFE ALL (Global Fail Safe Setting)
This selection allows you to easily determine the ser-
vos fail safe positions in a manner similar to the BASE
submenu Fail Safe:
Press the INC or DEC button at right of the display
to move the bracket to the FAIL SAFE ALL line and
press the SET button to activate the value field. The
current setting highlights white. Change the param-
eter by pressing the INC or DEC
SAVE option appears.
Simultaneously, use the transmitter control elements
to move all the servos: those assigned in the MODE:
FAI-SAFE line, any others programmed to take a spe-
cific position during the switch-on phase of the re-
ceiver system, and those with a set fail-safe position.
In the bottom POSITION line, the current servo po-
sition is displayed for the selected OUTPUT CH, as
shown in the example below:

Press the INC or DEC button to change the line
option from SAVE to NO.
This saves the positions of all of the servos affected
by these measures and simultaneously transfers them
to the F.S.POS line so that the receiver can access
them during a malfunction.
Release the control elements of the transmitter.
