Environment:
This product has been surface treated for resistance to salt air and precipitation. This resistance is
limited however, and the system should be kept clean and should be inspected for signs of
corrosion damage regularly.
As in all moving mechanisms there is concern about ice interfering with operation. The system has
internal protection against damage from stalling the motors, but performance may be reduced.
The system should be considered fragile:
DO NOT APPLY LOADS OR FORCES TO THE PAYLOAD.
Connections:
This product has two components. The Servo System and the Joystick Controller Box. First
connect the Servo System and Joystick Controller box together using the 5 meter Interface Cable
The 7 pin connector end of the Interface Cable is attached to the Joystick Controller box and the 8
pin connector end is connected to the Servo System. Make sure the power switch is in the off
position (up – non depressed position). Now the power connection is attached to the Joystick
Controller Box. The mating connector is included. Be sure to use the proper gauge wire for this
connection as the unit can draw up to 6 Amps of current @ 28 VDC. See Joystick Controller
Pinout Section.
The Power Switch on the Joystick Controller Box switches on power to the entire system.
Power:
This unit has an internal regulator to allow operation over a moderate voltage input range. Best
operation is obtained at 28 VDC level, although operation is fully satisfactory down to 18 VDC and
up to 30 VDC. The peak current is about 6 amperes. Internal capacitors are provided to remove a
reasonable level of power line noise, however, capacitors should be added for long power line
wiring or if noise is induced from other loads on the circuit.
