DESCRIPTION
The MCW100C,E Time Proportional Rotary Position Controller provides
automatic grade or steering control of paving, trenching and curbing ma-
chines. The Controller uses a wand follower to sense the grade level or
steering command from a stringline or flat surface.
Two modules are housed in the case of the Controller. The grade sensing
module electromagnetically measures the machine's deviation from a grade
reference. The amplifier module receives the signal from the sensor module
and produces a voltage output to drive solenoid valves which, on a typical
paving machine, operate lift cylinders. Within the amplifier's proportional
band, the percent of time the output is on is proportional to the grade error. The
MCW100C,E may be used together with the MCW101 Time Proportional
Level Controller to control both parameters simultaneously.
FEATURES
•
May be mounted on either side of machine
•
Adjustable tracking force
•
Dual UP/DOWN lamps show deviation from setpoint in
RUN and STANDBY modes
•
Adjustable deadband varies sensitivity
•
Run/Standby switch permits operator to switch to
manual control

INSTALLATION - LOCATION The MCW100C,E can be mounted on either side of the The follower may be attached at a 45° angle upward. (See machine, oriented according to the location of the reference Figure 5.) and the follower should be positioned toward the surface or stringline. -
Page 6: Installation - Mounting
After the follower has been installed, adjust the spring on the hub so the follower exerts a very light pressure on the stringline or reference surface. Note that the flat of the hub is parallel to the top of the case when the MCW100C,E is at null 1829 Figure 8. -
