Section 4: Control Box
Wiring the Control Box
The control box has a 3-amp breaker that protects its
electronic components. Be sure to observe correct
polarity. The control box will not operate if hooked
up with reverse polarity.
The injection pump is protected by the helicopter cir-
cuit breaker. The injection pump will work but at a
greatly reduced volume if hooked up with reverse po-
larity.
1.
Connect power input wires (red is positive, black is negative) to a 28-volt direct current power
supply, protected by a 10-amp breaker (20-amp breaker for HL series Sacksafoam only). In this
case, 28-volts is the nominal charging voltage on a 24-volt system.
2.
Connect the nine pin plug to the socket on the back of the control box (pin 1 is positive, pin 2 is
negative).
3.
To install the optional remote dispense switch: locate a single pole, single throw switch on the col-
lective. Connect the blue wire from pin 3 to the switch. Connect the opposite pole on the switch
to ground (-24 VDC).
4.
Check that the control box and injection pump operate. Install the camlock cap on the foam outlet
port to prevent the dispensing of foam. Set the dispense time switch to five seconds. Turn the on/
off switch ON. Momentarily lift the dispense switch. The orange dispensing light should come on
and the injection pump should run for five seconds.
