Optional System Features
The following features may be included in your system; many of these features are controlled through the OCU
but impact MCU functionality.
Not all features are compatible with or available for all OCU types.
7.1
OCU Automatic Turn-Off
The OCU turns off automatically when the following events occur:
•
Battery discharge protection (battery is low)
•
Auto Off timeout expires (pre-set between 30 seconds to 30 minutes)
7.2
Motion Enable Features
7.2.1 Push To Operate (PTO)
In a PTO enabled system, there is a means of activation that must remain depressed continuously for the motions
to remain active. The actuator may take the form of a button in the end of each joystick, a bar or pad on the front
of the controller, or a button on the face or side of the controller.
•
Pros
–
Ensures continuous guarding; removal of pressure on the button, bar or pad cause instant cessation
of motion
•
Cons
–
Buttons can be hard to maintain and can cause operator fatigue
–
Bars and pads can be easier to maintain, but are difficult to implement in many controller designs
7.2.2 Push To Enable (PTE)
In a PTE system, there is a means of activation that only needs to be depressed momentarily before a lever,
joystick or button is activated for the motions to operate. The enable actuator may take the form of a button in the
end of each joystick, a bar or pad on the controller or most typically one or two push buttons on the face or side of
the controller. After the enable button is pressed, the operator has a few seconds (this time is configurable) to
start operating a motion; if this time is exceeded, the button must be pressed again. Once the motions are
activated and being used they will stay active until all motions are returned to the neutral position for more than a
few seconds (configurable), then the enable is required once more.
•
Pros
–
Easy to use
–
Protects against accidental activation before the motion is enabled
•
Cons
–
Once activated, if an additional lever is accidentally deflected, protection will require removal of the
deflecting mechanism or pressing the Stop button
