FT7000, RACK MONITOR MANUAL 11033PA-ATEX
Loading Procedure
The rack monitor will default to a NON-PERMISSIVE mode. While non-permissive, the non-permit
indicator will be illuminated and the rack will continually check for 5-Wire and 2-Wire trailers.
Once the monitor is connected to a trailer it will identify the type of sensors (5Wire or 2Wire) and lock
into that mode. The detected sensor type will be indicated by a green light next to 5W or 2W on the
front of the monitor. Trailers having 2W analog sensors may take longer to identify, as the sensors must
warm up before they activate. The monitor will then verify the incoming signals from the
sensors/monitor are within the acceptable tolerances.
The monitor will continuously check for any of the enabled ground devices. If no ground devices are
enabled in the monitor configuration, the monitor not require any ground verification to become
permissive. Once a valid ground device is found, and the overfill sensors are detected as dry, the
monitor will become permissive.
The FT7000 will remain permissive until any requirement is lost. During a normal load, the FT7000 will
remain permissive throughout the entire load, then become non-permissive as the trailer disconnects.
While the monitor is permissive it will continually verify that the overfill sensors are dry, and the ground
device is connected. If a sensor becomes wet, the monitor will immediately become non-permissive.
While the sensor is wet, and the trailer is still attached to the rack, the LINX feature will activate to
indicate an overfill has likely occurred.
NOTE: INTERMITTENT CONNECTIONS WILL PREVENT THE MONITOR FROM STAYING PERMISSIVE
THROUGHOUT A LOAD.
NOTE: IF AN ESTOP IS TRIGGERED, THE MONITOR WILL BE LOCKED IN THIS STATE UNTIL A BYPASS KEY
IS READ BY THE MONITOR.
