2. Direction input signal. (see Fig. 5)
In order to select a direction, the controller
requires a +36 volt input to terminal 12 for a
forward command or +36 volts to terminal 11 for a
reverse command. The signal originates from two
solid state switches in the foot pedal control. The
foot pedal control at terminal A (green wire)
re36 volts from the key switch circuit and
is fed into the solid state directional switches. As
the foot pedal is rotated forward from the center
position, the forward switch closes s36
volts out terminal C (white wire) of the foot control
to terminal 12 at the motor controller. For reverse
direction, +36 volts leaves the foot pedal control
from terminal B (black/white wire) and is fed into
terminal 11 at the motor controller.
3. Speed reference input signal. (see Fig. 6)
The motor controller uses a 0--5 volt signal at
terminal 6 at the motor controller. To determine
the speed of the propel motor.
4. Mode select inputs. (see Fig. 7)
The propel controller is programmed to operate in
three modes:
----Transport (mode 3)-- allows for maximum
speed
----Sweeping (mode 4)-- reduces the speed for
optimum sweeping
----Hopper up (mode 1)-- reduces the speed when
the hopper is raised.
A). When +36 volts is applied to terminal 9 of
the controller (as when the hopper down switch is
closed), the maximum speed will be allowed.
B). When +36 volts is applied to terminal 14 of
the controller (as when the main brush switch is
closed), the maximum speed will be reduced to
4.5 MPH.
C). When +36 volts is applied to neither
terminal 9 or 14 of the controller the maximum
speed will be reduced to 3 MPH.
