Recovery Tank-Full Switch Orientation:
FACTORY DEFAULT: 0 (Normally Open Position)
The Warrior control board now has a programmable option to allow it to work with a normally-open or normally-closed recovery tank full switch.
Note: The normally-open con fi guration is used when the fl oat switch is installed such that the fl oat hangs down when the tank is empty, then fl oats up
to the horizontal position when the tank is full. (See Figure 3 in Recovery System/Maintenance of Recovery Tank Float Switches.) In the normally-
closed con
fi guration, the fl oat remains horizontal when the tank is empty, then fl oats up when the tank is full.
All current machines use the normally-open fl oat switch con fi guration, and have the programming option available in the main controller to
allow you to change the switch orientation to either normally-open or normally-closed. Earlier machines used the normally-closed con fi guration
only and did not have the switch orientation programming option available. If the main controller on your machine does not have the switch
orientation programming option available (as described below), you must run the machine with the switch in the normally-closed con
fi guration.
Note that controllers on AXP machines with software revision level “I” or later, and controllers on ST machines with software revision level “E”
or later will have the switch orientation programming option. Refer to the
Displaying the Control Unit Revision Level subsection for instructions
on how to view the software revision level of your controller.
To change the fl oat switch orientation option, perform the following steps:
Turn the main power key switch to the off position. 1.
2
Press and hold the scrub system off and vacuum switches.
3 While holding both switches turn the main power key switch to the on position.
4 Continue to hold both switches until only the vacuum indicator is lit (approximately 2 seconds).
5 Release both switches. The status or LED display will now indicate “0” or “1” and the scrub off indicator will be red.
6 Pressing and releasing the vacuum switch will now select between “1” for the normally closed con fi guration or “0” for the normally open con fi guration.
7 To save the new setting, press the scrub off button. The scrub off indicator will change from red to green.
8 Turn the main power key switch to the off position. The new setting will be saved and will remain in effect until it is changed again.
