receivers is recommendable for large models, for
example to avoid long servo cables. In this case,
remember that only the receivers selected in the
"RECEIVER SELECT" line can be addressed by the
"Telemetry" menu.
The 9 or 12 control channels (INPUT CH) of the
mz-18 HoTT and mz-24 HoTT transmitters can be
correspondingly administered by assigning the servo
connector of the receiver selected in the OUTPUT CH
line to the INPUT CH of another control channel by
"channel mapping".
NOTE:
If for example you entered "2AILE" in the
basic settings for a model memory, the
transmitter assigns control function 2 (aileron)
to control channels 2+5 for the left and right aileron. The
corresponding INPUT CH of the receiver to be mapped
would in this case be channels 02 + 05 (see the
example below).
Examples:
• On a large model, you want to control each aileron
flap using two or more servos:
Assign the relevant OUTPUT CH (servo connectors)
as the INPUT CH to one of the two default aileron
control channels 2 or 5 depending on the left or right
wing.
• On a large model, you want to control the rudder
using two or more servos:
Assign the same INPUT CH (control channel) to the
relevant OUTPUT CH (servo connectors). In this
case, default rudder channel 4.
MODE (method)
The settings of the options "MODE", "F.S.Pos." and
"DELAY" determine the response of the receiver
when there is an interruption in transmission from the
transmitter to receiver.
The setting programmed under "MODE" always refers to
the channel set in the line OUTPUT CH.
The factory setting for all servos is "HOLD".
For each selected OUTPUT CH (receiver servo chan-
nel), you can select between the following:
• FAI(L) SAFE
With this selection, the corresponding servo
moves into the position displayed in µs in the line
"POSITION" in case of a malfunction after expiration
of the delay set in the "DELAY" line for the remainder
of the malfunction.
• HOLD
With the "HOLD" setting, over the course of a mal-
function, the servo remains in the last correctly re-
ceived servo position.
• OFF
With the "OFF" setting, over the course of a malfunc-
tion, the receiver stops transmitting (buffered) con-
trol pulses for the relevant servo output. The receiver
switches off of the pulse line in a manner of speak-
ing.
NOTE:
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 connector), after
activating the value field (red parameter) by touching
the SET button at the bottom right of this display,
set the servo position for the servo to assume in a
malfunction in "FAI(L) SAFE" in the line "F.S.POS." by
using the INC or DEC buttons. The setting is made in
10-µs increments, for example:
Graubele
VARIO
GPS
ENT
SET
ESC
RX FAIL SAFE <>
INPUT CH: 01
MODE : HOLD
>F.S.POS : 1150µsec
DELAY : 0:25sec
OUTPUT CH: 01
FAIL SAFE ALL: NO
POSITION : 1100µsec
BACK
RECV
GENE
ELEC
DEC
INC
ESC
Factory setting: 1500 µs (servo center).
Important note:
In all three modes "OFF", "HOLD" and "FAI(L)
SAFE", the function "F.S.POS." is particularly
important when waiting for a valid signal after
turning on the receiver:
The servo immediately moves into the fail safe positions
set in the "POSITION" line. This prevents landing
gear from retracting when the receiver is accidentally
switched on while the transmitter is off. In normal model
operation, the corresponding servo contrastingly acts
according to the set "MODE" in a malfunction.
DELAY (fail safe reaction time or delay)
Set the delay after which the servos are to move to their
set positions when the signal is interrupted. This setting
is adopted by all the channels and only affects the
servos programmed for "FAIL SAFE" mode.
Factory setting: 0.75 s.
