Proton Products SL mini and SLR mini Series Speed and Length Gauges Instruction Manual - issue 1s
Note: If the default resolution of 1=0.1 m{ft}{yds}{inch}of the “Length Offset” (DW14) parameter is too
large, then an enhanced resolution “Length Offset” of 1=0.001 m{ft}{yds}{inch} can be factory-enabled
in the SL / SLR gauge.
EXAMPLE IMPLEMENTATION USING BANNER QS18 LASER EMITTERS AND
QS186LE NPN SENSORS
DB25 INTERFACE Socket Connection
When no object is present, laser light from the QS186LE laser emitter illuminates the QS18 NPN
sensor and its SIG output is pulled low; hence the SL / SLR gauge “Length hold” function must be set
to “active low”.
SL / SLR gauge configuration using the optional AiG2 display unit:
Navigate to the “Interface” menu and then navigate to the following submenus:
Logic input function:
Select “Length hold” for logic inputs 1 and 2.
Select “Reset length” for logic input γ.
Logic input active state:
Select “Active low” for logic inputs 1, β and γ.
Navigate to the “Measurement” menu and then navigate to the following submenu:
Length offset:
Set a positive value corresponding to distance “L”.
