Control Panel
Functional Description
The control panel is an integral component with the Main controller
(A1)
circuit board. The controls on the 34 RST
were designed with
one touch operation
in mind. For single-pass scrubbing the user can simply depress one switch
and all systems on the machine will be ready to go. For most single-pass scrubbing operations, the operator should
only need to use the middle switches on the control panel. These are the Scrub System OFF and Scrub System ON
switches.
Key Switch (A):
The key switch serves as a main control switch to enable or disable operation of the machine.
The key is removable to prevent unwanted operation when not in use. The key switch doesn’t disconnect any power
circuits, but instead, sends a signal to both the Main controller and Curtis Drive controller to indicate the On/Off
function.
Solution Switch (B)
- This switch is used to turn the solution system on or off and select the solution flow rate.
Pressing this switch when the scrub system has been activated will increment the solution flow rate as displayed
on the Solution Flow Indicator
(D1)
. The solution flow will turn on when a
Palm Drive Button (29)
is pressed
with the Reverse Button released (the forward drive position). The solution flow will turn off if both
Palm Drive
Buttons (29)
are released. Pressing the
Solution Switch (B)
when the scrub system is off will momentarily turn
the solution flow on (at the high flow rate) to allow pre-wetting of the scrub brushes. Pressing and holding in the
Solution Switch (B)
when the scrub system is off will allow continuous solution flow for as long as the switch is
depressed.
Scrub OFF Switch (H)
- Pressing this switch when the unit is in a scrub mode will cause the following to occur:
• The scrub brushes will turn off and the scrub deck will be raised to the up position.
• The solution flow will be stopped.
• The first time that this switch is pressed, the vacuum system will NOT be turned off. This is so that any
remaining water may be picked up without having to turn the vacuum back on. If this switch is pressed a second
time or if the machine is stopped (after the scrub system has been turned off), the vacuum will shut off after a 10-
second delay.
Scrub ON Switch (I)
– If the scrub system is off, pressing this switch once will cause the following to occur:
• The scrub system will be enabled with the scrub pressure set to the “Regular” (“Normal”) mode (#1) and the scrub
deck will be lowered. Note that pressing the Scrub-ON switch twice will set the scrub pressure to the “Heavy”
scrub pressure mode (#2). Pressing and holding the Scrub-ON switch in for five seconds will set the scrub
pressure to the “Extreme” scrub mode (#3).
•
The vacuum system will be enabled.
•
The solution system will be enabled.
•
As soon as either of the
Palm Drive Buttons (29)
is pressed, the scrub brushes will start turning and the
vacuum will turn on. If the direction is set to forward, the solution flow will start. If the
Reverse Button (28)
is pressed, the solution flow will be stopped. If the scrub system is already enabled when the Scrub ON Switch is
pressed, the scrub pressure will increase to the “Heavy” scrub mode (#2). If the Scrub ON Switch is pressed and
held in for 3 to 5 seconds, the scrub pressure will change to the “Extreme” scrub mode (#3). Note that the
Scrub
Pressure Indicator (J2)
on the panel display will show the current scrub pressure setting (1, 2 or 3).
Note:
Both the scrub pressure and the solution flow rate will return to their default settings when the key switch is
turned on again after the machine has been switched off.
Vacuum Switch (C)
– This switch is used to turn the vacuum system on or off. Pressing this switch will alternate
between on and off. The vacuum will only turn on when a
Palm Drive Button (29)
is pressed. It will remain on
for 10 seconds after the
Palm Drive Buttons (29)
are released.
The vacuum also has an automatic shutoff feature that will turn the vacuum and scrub systems off if the recovery tank becomes full.
Wand Switch (E):
This switch is used when an external vacuum/scrub wand is used. Pressing this switch will
turn the vacuum on continuously without regard to the throttle position. If the scrub system was on it will be turned
off. This includes turning off the scrub brushes and turning the solution flow off (to the scrub deck).
Note:
automatic
shutoff of the vacuum motor when the recovery tank is full is disabled when the wand is enabled.
