CAN RANGER OPERATION
4
If the transmitter is on, and
one or more of the valve
handles/actuators is moved
off center beyond the Engine
Stop position, by means other
than the transmitter (for
example if a spring return
fails or someone moves a
handle) the CAN Ranger will
stop the engine. This is a
safety feature to protect the
person using the transmitter
from someone else operating
the machine without their
knowledge. The Engine STOP
position is configurable for
each valve handle, and for
each direction. They can be
configured via the PALM or by
following
the
ACTUATOR
CALIBRATION
procedure
listed below. NOTE: The
Engine Stop values must be
between 90% and 10% of the
FAST value.
When
turning
off
the
transmitter the STOP ENGINE
output will activate for about
5s and then turn off to
energize the Engine stop relay
on the harness. This action
will open the NC contact on
the relay to stop the engine.
The normal configuration for
the actuators is to have the
actuators release the manual
handles when a function is not
active, or when in E-Stop
mode. For valves with weak
springs, the corresponding
actuator can be configured to
automatically return back to
center.
In order to operate the crane
manually with at least one
actuator in Auto Center mode
enabled, turn off the Receiver.
Otherwise the actuator will
