FIGURE 35: VT300 POWER INTERFACE BOX
Power Interface Box
The VT300
™ Interface Box is the connection point for vehicle power supplies, PC control, and tether
deck cables. The Interface Box is also the main power input for the system and provides fusing and
handling of system alarms.
The Interface Box is a 120VAC unit and requires a power feed rated for at least 25A. The power cord has
been fitted with a 30A rated circular L5-30P locking plug.
Controls and Indicators
ON Button
–
When powering up the
ON
button must be held for approximately two seconds (buzzer will
beep). The ON button will illuminate whenever power is on. If a fault is detected causing the main power
supplies to automatically shut down the
ON
button will flash to indicate a problem.
OFF Button
–
The
OFF
button will cut power to the power supplies, vehicle, and Interface Box. The
OFF
button may be used as an emergency stop but during normal operation the vehicle should be brought to a
full stop with lights off before turning the system off.
Note:
Pressing the
OFF
button while the vehicle is in full operation is hard on both vehicle electronics and
power supplies and may reduce the overall life of components.
System Monitor
– The system monitor is used to indicate the status of the power supplies and the 420
Volt ground fault detector.
•
PS1 / PS2 Fault
–
The power supply units have individual short circuit and over-temperature
protection. Should one of the power units turn itself off or otherwise fail a fault will be indicated
here. The Interface Box will then disable both power supplies to protect against overload.
