After the start button is pushed, there is a time delay before the floor begins operation. This delay
keeps material from feeding into the rotary air valve until the auto-reverse duration has passed.
In the case of multiple auto-reverse cycles, it keeps the transition area above the rotary air valve
clear of any new material. There is also a time delay for the pressure switch. Since the electronics
can reset faster than the hydraulics, this time delay activates the pressure switch after its set time
passes following an auto-reverse cycle. This small amount of time, approximately 0.4 seconds,
allows the relief valve to fully close and the flow switch to return to the open position, eliminating a
false signal that would trigger another auto-reverse cycle.
When the STOP button is pushed, power is cut to the floor and rotary air valve solenoids. Turning
off the ignition key can also stop the hydraulics. Please note that the hydraulics will also stop if
either transition door between the floor and the rotary air valve is opened and cannot be restarted
unless the doors are closed and the START button is pushed.
SUBSYSTEM 4: RADIO REMOTE TRANSMITTER
This Bark Blower is equipped with a Radio Remote Transmitter to control the Material-Feed Start/
Stop feature. It also contains an Emergency STOP button, that activates the safety shutdown
system on the engine and the engine throttle control. To activate the remote, simply set the toggle
switches on top of the transmitter, and on the control box to the ON position. The two indicator
lights on the top will begin alternately flashing. When they are no longer flashing, the unit is on and
ready for operation.
To utilize the Material-Feed Start/Stop feature of the Radio Remote Transmitter, the initial start
must occur at the Start/Stop station on the Bark Blower. The hard-wired Start/Stop on the unit is
the primary and overriding set of controls. Pressing the STOP button, as well as a loss of power
to the Material-Feed Control (i.e., an open transition door or blown main fuse), deactivates the
Material-Feed Start/Stop feature of the Radio Remote Transmitter until power is restored to the
Material-Feed Control and the START button on the machine is pressed.
