P350 flexitrax Operation Manual 49
Manual mode
In Manual mode, the crawler will drive with no assistance from the drum.
NOTE: A message will flash on your screen warning of a cable hazard. This message will not be recorded to video.
Press ▼to reverse the crawler. Increase the speed by holding or pressing ▼. Decrease the speed by holding
or pressing ▲ .
Ensure that you wind in the cable at the same or higher speed than the crawler as this may cause the crawler to get
entangled in the cable and stall. Use the crank handle to aid reversing.
Automatic mode
This mode is primarily for powered drums. It allows the user to drive the crawler at constant speed in either direction
with assistance from the powered drum. When driving forwards, the user controls the crawler speed. When driving
backwards, the user sets a target cable speed. The drum will automatically adjust its speed to maintain a constant
cable speed as it pulls the crawler backwards.
Pressing ▲, while the crawler is pulling or still, will increase the crawler speed. Pressing ▲ while the drum is
pulling will decrease the target cable speed.
Pressing ▼, while the drum is pulling or still, will increase target cable speed. Pressing ▼ while the crawler
is pulling will decrease crawler speed.
NOTE: In Automatic mode, the mimic speed bar is disabled. The crawler’s speed is automatically set to match the
retrieval speed of the cable. Steering is disabled in automatic mode.
NOTE: Crawler wheel size must be correctly set for Auto and retrieve modes to function correctly. Failure to set correct
wheel size could result in damage to the system.
Powered drum
Moving forward
To move the crawler forward, press ▲ .
Pressing ▲ repeatedly will increase the crawler speed (forward). Holding the ▲ key will accelerate the
crawler until it reaches maximum speed.
To slow the crawler, press ▼.
Subsequent or sustained presses will decelerate the crawler faster until it comes to a stop.
NOTE: If you continue to press ▼when the crawler has stopped, it will move in reverse.
Reversing
NOTE: The crawler will automatically stop when the cable counter reaches 0.0. However, the crawler’s momentum
may cause it to roll a short distance beyond the 0.0 position. Please allow for this when you deploy the camera and
zero the distance counter.
The powered drum supports two driving modes: Automatic and Manual. In Manual mode, the crawler and drum operate
independently. Manual driving gives you more control over the crawler and drum but can increase the risk of jamming
the cable around the crawler wheels, particularly if the crawler reverses over the cable. Press F3 to toggle between
Auto and Manual driving modes. This is displayed in the top left of the display.
From a stationary position, press ▼ to reverse the crawler (or down on the crawler drive controls).
Pressing ▼ repeatedly will increase the crawler reverse speed (except on the gamepad controls).
Decrease the speed by holding or pressing ▲. If you continue to press ▲ when the crawler has slowed to a
standstill, the crawler will start moving forwards (except on the gamepad controls).
In automatic mode, the powered drum will automatically retrieve the cable as the crawler reverses. To avoid
the risk of jamming the wheels in the cable, the crawler will reverse at a slower speed than the cable.
In manual mode, the drum will not retrieve the cable and you must synchronize the speed of the crawler and
the cable. To rewind the cable in manual mode, hold the Fn key and press ▼ on the keypad.
Decrease the speed by pressing Fn + ▲ together.
The system will stop when the Auto Stop limit or the zero point are reached.
