Options box
Night light switch
The switch shown in Figure 13 is used to activate the
optional night light kit.
Concrete shut-off valve switch
The bottom of the two switches (Figure 14) is used to
control the function of the optional concrete shut-off
valve.
The three position switch allows the operator to control
the function of the valve in three different modes:
• Position number “1” is “Auto-mode”. This
mode should be used for normal operation.
The shut-off valve will work in relationship to
the concrete pump on-off switch. When the
machine is pumping, the concrete shut-off
valve is open; when the pump is stopped,
power is removed from the solenoid, and the
valve inflates to stop concrete from draining
out of the boom. The valve can be overridden
via the remote box. If you are standing near the
boom with the remote box and wish to drain
the concrete from the boom, activate the switch
in Figure 15 to the down position, which is the
concrete shut-off icon, and the valve will open.
The switch is located to the left of the E-stop
button on the remote box.
• Position number “2” closes the valve full time.
NOTE!
Do not activate the concrete pump in this
mode with full air pressure on the valve.
Damage could occur!
• Position number “3” supplies power to the
concrete shut-off valve full time and disables
the valve. This position can be used instead of
the
disable switch
shown in Figure 15 to allow
the boom to drain prior to inserting a cleanout
ball or any time the concrete needs to be
removed from the boom by gravity.
