Overview
Wet / Dry Switch
The Wet / Dry switch works in combination with the
optional low pressure switch and has two positions,
wet and dry. See Figure 23-1.
In the Wet position, the optional low pressure switch
becomes part of the safety circuit.
• When the water pressure at the low pressure
switch reaches the set PSI, the low pressure
switch will close which completes the safety circuit
and allows the machine to run.
• If the water pressure drops below the set psi while
the machine is running, the machine will shut
down due to low pressure.
In the Dry position, the optional low pressure switch
is by-passed, removed from the safety circuit and the
machine will run without water pressure.
NOTE
• If the switch is left in the DRY position when
the operator is applying water the machine
will NOT shut down if the pressure falls be-
low the low pressure switch setting.
Auto Reverse / Auto Stop Switch*
The auto reverse / auto stop switch controls the auto
reverse and auto stop function and works in combina-
tion with the drive unit mounted auto reverse/auto stop
mechanism and has two positions, Auto Reverse or
Auto Stop. See Figure 23-2.
In the auto reverse position, the machine will reverse
direction when the end of field stop mechanism is ac-
tivated.
In the auto stop position, the machine will stop when
the end of field stop mechanism is activated.
* Only available on control panels equipped with Auto Reverse/
Auto Stop.
