OSS Component Installation
THE FOLLOWING ILLUSTRATIONS PROVIDE KEY INSTALLATION
INSTRUCTIONS FOR THE OSS TO OPERATE PROPERLY.
• The OSS Control Module must be electrically isolated
from the mast, see installation instructions below.
• The sensor shield tubes attached to the platform’s
under sides must be properly installed and undamaged
to prevent sensor detection of objects outside the plat-
form parameter.
• The area under the platform floor must be free of any
objects or debris dangling from beneath the platform to
avoid false detection by the sensors.
• DO NOT allow high pressure spray to directly contact
the transducer sensor (circular) membrane, this will
damage the sensor.
