Configuration
The system operation is a function of deadband setting, gain selection,
laser RPM, machine speed, hydraulic pressure and flow, installation
settings, and general site or field conditions. The user selectable factors
of the control box are the deadband, the gain and the LED displays.
Two rotary switches are provided for selecting the on-grade deadband
(10) and the gain (12), while a dip switch (11)
provides for LED display
selections. These switches are located
behind the access panel on the
bottom front of the control box. Turn the 2 thumbscrews counterclockwise
and remove the panel from the box housing to access the switches.
On-Grade Deadband (Accuracy) Selection Switch (10):
The on-grade deadband rotary switch (10) provides 16
positions of deadband selection with "0" being the smallest
and increasing clockwise to "F" which is the largest. The table
below lists the corresponding on-grade deadband for each
switch position. Each number or letter setting represents an
increment of one-tenth inch (0.10 inch) or approximately 2.5 mm.
0 1 2 3 4 5 6 7
in. 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7
mm 0 2.5 5.1 7.6 10.2 12.7 15.2 17.8
8 9 A B C D E F
in. 0.8 0.9 1.0 1.1 1.2 1.3 1.4 1.5
mm 20.3 22.9 25.4 27.9 30.5 33.0 35.6 38.1
NOTE: The MCR1+ uses 10 positions from "0" to "A" for a deadband
range of 0 to 1.0 inch (2.54 mm). Positions "B" to "F" remain at the 1.0
inch deadband. Other MCR receivers use all the positions.
Examples:
The deadband setting of "5" would correspond to ½ in. (12.7 mm).
The deadband setting of "A" would correspond to 1.0 in. (25.4 mm).
The default on-grade deadband is set to "8" or 0.8 in. (20.3 mm).
