P350 flexitrax Operation Manual 37
Pressing subsequent times will increase the crawler
reverse speed incrementally.
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.
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 however, 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. Hold this key
combination to accelerate the rewind speed.
Decrease the speed by holding or pressing Fn + .
As already mentioned in section 5.2.4 the system will stop
reversing when the Auto Stop limit and the zero point
have been reached.
CAUTION! In manual mode, make sure the cable
is retrieved faster than the crawler speed. This will
help to avoid the risk of jamming the cable in the
crawler wheels.
Automatic retrieval
The powered drum features an automatic retrieval
function. This function is designed to retrieve the crawler
at a constant, optimal speed. This speed cannot be
altered.
To use automatic retrieval you must set the 0.0m/ft
position before you start the survey. To set the 0.0
position press and simultaneously when the crawler
is in the position you wish to retrieve it to.
NOTE: Automatic retrieval does not work when the
counter is displaying a negative or zero measurement.
To retrieve the crawler, select the RET option from the drive
menu. The system will ask you to confirm the currently
selected wheel size. Make sure this matches the wheel set
installed on the crawler and press OK to continue.
Press GO to begin retrieving the crawler. The
crawler will automatically stop once the cable
counter reaches the 0.0 position or the Auto Stop
point (if set).
Press CANCL to cancel the operation and return
to the drive menu.
Manual retrieval with the crank handle
If necessary, you can retrieve the crawler using the crank
handle to manually wind the cable back into the drum.
Before you start, disconnect the power lead to ensure
that the system is not powered.

The crank socket is located under the side panel closest
to the controller socket. The panel is secured with socket-
head screws. Remove this panel using a metric Allen key.
Figure 5.14: Crank handle for powered drum
Attach the crank handle to the crank socket located in
the gear on the top right-hand corner of the compartment
using the supplied socket head screws.
Figure 5.14 illustrates the crank handle installed in the
powered drum. Note the installation point.
CAUTION! Remove the crank handle and replace
the side panel before reconnecting power to the system.
5.3.8 Steering (P356 crawler only)
NOTE: Steering the P356 crawler is identical for both
the powered and manual system.
You can steer the P356 crawler left and right, allowing
you to navigate pipes with ease. The crawler steers by
changing the speed on the left or right motor.
You can steer the crawler when it is moving forwards,
backwards or when it is stationary. Steering whilst
reversing is possible in manual driving mode only.
Note: Steering whilst moving is proportional to the crawler
speed: the faster the crawler moves the bigger the steer.
When the crawler is stationary, it will turn on its own axis.
Be careful when turning in this fashion as the crawler may
become entangled in the cable.
To steer right, press . Hold the key to turn faster.
To steer left, press . Hold the key to turn faster.
