Braking With More Than One Servo (Profi Car 707 Only) - Multiplex PROFI CAR 403 Operating Instructions Manual

5.4.

Braking with more than one servo (PROFI CAR 707 only)

If you have chosen the „4 CH" or „5 CH" vehicle type, you can use two brake servos;
this allows you to control the brakes for the front and rear axles separately.
In vehicle type „4 CH" you have:
v
servo 2 for throttle/brake (rear wheels)
v
servo 3 for the second brake (front wheels)
In vehicle type „5 CH" you have:
v
servo 2 for throttle alone
v
servo 3 for the first brake (rear wheels)
v
servo 4 for the second brake (front wheels)
When you select one of these vehicle types, you can adjust the brakes using the „
menu, where you will find the menu points „BRAKE1" and „BRAKE2", both of which
feature the same parameters (idle ID, engage point EP, lock point LP and EXPO).

Setting of the brake servos when you open the throttle:
If a combined throttle/brake servo is connected to channel 2, the servo responds to
the throttle and brake commands, but if there is a separate brake servo (servo 3 or 4),
it only moves when the trigger is moved into the brake range. As soon as you open
the throttle, these servos jump to a fixed position which we can term „brake fully off".
The servo position for „brake fully off" can be set for servos 3 and 4 in the menu point
„S-TRAV" within the „
trigger in the throttle range. You will see the symbol „L" on the screen.

TIP !
Brake engaged when the trigger is in the deadband (finger relaxed):
If you want the brakes in
your model
operate in this way, you
must set the engage
point to 0. Instead of the
0 you will then see „OFF"
on the screen. If the
brake servo is program-
med in this way it will
behave as shown in the
diagram at far right. The
servo no longer jumps to
the engage point when
the trigger is moved out of the deadband.
