MCW100A, B
Time Proportional
Rotary Position Controller
BLN-95-8966-4 |
Issued: March 1992 |
DESCRIPTION
The MCW100 Time Proportional Rotary Position Controller provides auto matic grade or steering control of paving, trenching and curbing machines by switching an on/off solenoid valve. The Controller uses a wand follower to sense the grade level or steering command from a stringline or surface.
Two modules are housed in the case of the Controller. The grade sensing module electromagnetically measures the deviation between the true grade ofthemachinethroughthefollower.Theamplifiermodulereceivesthesignal
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 MCW100A and B are the same with three exceptions: First, the “A” unit is switched on the hot side while the “B” unit is switched on the ground side. Secondthe“A”hasaninternalgrade/slopeswitchthat the“B”doesnothave.
Third, on the “A” model the deadband adjustment is a multiple turn potentiometer and on the “B” model it is a single turn trim potentiometer.
