The Emergency Alert (audible and LED) can be activated by pressing any two buttons on the
hand control at the same time (provided with the lift). This will stop all lift movement and activate
the audible alert and the Red LED will flash. Once both buttons are released, the lift will return to
normal operation and the emergency audible alert will silence.
USB Port
–
The LiftOperator® control contains a USB port that is used to download the performance log of
the lift. Using any standard FAT file formatted USB memory stick (widely available through retail
outlets) insert the stick into the slot on the bottom of the control on the far right hand side. Press
any of the touchpad
control arrows; all three of the Battery Level LED’s will flash. During
downloading the Green greater than 50% Battery Level LED will flash. If the unit has a problem
downloading the performance log the Red less than 25% LED will flash. Remove the USB from
the port and re-insert it. If the Red 25% LED flashes again, confirm that the USB you are using is
FAT file formatted. The information from the USB can be downloaded to a PC for review and/or
copied to a spread sheet. The performance log will retain approximately 7,600 events. Once the
file is full it will remove the oldest event and replace with the newest.
After the summary data, the events are shown with the oldest first. The first column is the time in
seconds from that last event. The second column is the text describing the event. The third
column is duration of the activity noted in seconds.
