If either button, (“UP” or “DOWN”), on the controller is pushed while the waterway is
pressurized all three LED’s will blink on and off at a very rapid rate. They will continue to blink
until the waterway pressure is less than 8 PSI and the operator pushes either the “UP” or
“DOWN” button. If the elevator is moving when the waterway becomes pressurized then the
Extender will immediately stop and all three LED’s will blink on and off at a very rapid rate.
The Extender will not move until the pressure is less than 8 PSI and the operator resets the
system by pressing either the “UP” or “DOWN” button. Pushing the “UP” or “DOWN” button will
stop the flashing LED’s reset the LED’s back to their normal mode of operation and start the
unit traveling in the chosen direction.
NOTE: Once the pressure has been released and the unit has been reset, all functions will
return to their normal mode of operation.
