OPERATION
5.1 Instruction for Use
Once the SMART hatch is installed and operational, no operator intervention
except replacing the battery in the hatch-mounted sensor is required (see
Section 4.3.4). The in-cab display shows the battery status. Only trained
service personnel should access the SMART
hatch system.
5.2 Operating Controls
The SMART hatch system does not contain any operator controls and
automatically provides data for drum rotation, concrete temperature, air %
and battery charge level provided the following conditions are met:
•
A minimum of approximately two (2) yards of concrete in the drum
•
The drum is rotating in the charge direction between 0.5 rpm and 6 rpm
•
The concrete slump is greater than approximately 2 inches
•
The concrete water-to-cement ratio (w/c) is greater than
approximately 0.3
Once the above conditions are met, the SMART hatch sensor will begin
initialization. Initialization is complete when the drum is rotated in the charge
direction, between 0.5 and 6 rpm, for eight (8) revolutions. Once the eight (8)
revolutions are achieved the concrete air percent and temperature will be
displayed.
5.3 In-Cab Display
The in-cab display shows concrete air content (%), concrete temperature (
°
F or
°
C), drum speed (rpm) and sensor battery charge level (% remaining).
The In-Cab Display has four pushbuttons as shown in Figure 24.
Press left-most button to display the menu. Press the left/right arrow buttons to
navigate through a menu. Press the right-most return key to select a highlighted
menu item. At any time when the menu is displayed press the left-most button to
exit the menu without making a selection.
