Connecting Power
The power requirement to control the Bambi MAX valve is 5 amps, 24/28 VDC. The Bambi MAX comes
with a three-conductor, 16-gauge control cable that comes from the valve to 3' above the head. Attached to
the end of the cable is a male waterproof Nema 5-15 electrical plug (the female receptacle for the helicopter
is attached). If an additional plug is required, an IP67 or better must be used.
The purpose of this type of plug is to offer a clean breakaway if the Bambi MAX has to be jettisoned from
the aircraft in an emergency. It is suggested that the plug be lightly taped together with vinyl tape, while in
use, to ensure that wind action does not separate the plug during flight.
There are three types of suggested
wiring installations (see
Appendix
for
diagrams).
1.
Pilot control:
In this
configuration, the control is
wired into the pilot's control
column through a relay.
2.
Pilot control (US
interagency):
In this
configuration, the control is wired into the pilot's control column through a 50 amp relay as per US
interagency regulations. This system can also be used to control a heli-torch, etc.
3.
Crew control (remote power supply):
This configuration allows a crew member or a pilot to
control the dumping of the bucket using a battery pack to supply the power to the remote switch.
This also eliminates the high cost of pre-wiring the aircraft.
Using Longlines
Longlines should be at least 50 ft. long to keep the Bambi MAX well clear of the helicopter’s tail rotor.
When using a longline, care must be taken in selecting the correct gauge of control cable. See the chart
below for recommendations.
When purchasing a synthetic rope longline, we recommend that the customer also purchase a protective
cover and have the conduit inserted at the time of manufacture. However, if this is not feasible due to
different conduits for different applications, we recommend taping the conduit using duct tape (grey) at 3-4
ft. intervals along the longline and cover.

Important Note
It is recommended that operators, who choose to use the Bambi MAX with a longline, ensure that
the longline is at least 50’ long.
