Description of function:

Reverse front attachment The front attachment must not be engaged as a pre-condition for the
reversing function. The speed monitor module (A12) connects voltage to
the reverse switch (S57) as an additional safety feature only after the
feeder housing speed sensor (B12) stops transmitting a signal for approx.
2 seconds.
If these pre-conditions are met, voltage is connected from the speed
monitor module (A12) to solenoid coil (Y86) via the reverse switch (S57) -
Front attachment reverse function.
The master valve (Y77) is actuated via the diode PCB (DO) in parallel
with the solenoid coil (Y86) because this function requires that pressure is
built up in the system.
Important! When reversing is activated, a signal is connected to the
reel controller module (A16) which makes the reel drive
variable-displacement pump swing to maximum delivery,
depending on the front attachment identification – Circuit
