H-16 Controller Power
The H-16 system has separate switched and
unswitched power networks. The primary switched 24 V
network powers the solenoids that control head
movement, via the software. The constant unswitched
24 V control network (stepped down to 5 V to run the
circuits) allows a soft shut-down when the Waratah
switch is turned off. It cannot supply power to the
solenoids.

Carrier Reset and Interlock
Note that some carrier models have an additional reset
switch, mounted at the cab door or armrest, to enable or
disable electric and hydraulic systems.
Some carrier hydraulic control systems include
interlocks, which will disable the carrier’s hydraulic
power when activated.
