P350 flexitrax Operation Manual 47
NOTE: Resetting or varying the distance counter during a survey will render the automatic retrieval function ineffective
as the crawler will return to the new zero position and not the point where the crawler began the survey.
In custom layout you can move the OSD counter field around the screen to suit your preferences. See Section On-
screen display (OSD) for more information.
Sonde
The P350 crawlers feature an integrated, multi-frequency sonde. The Sonde allows you to locate the crawler’s position
using a Radiodetection cable and pipe locator such as an RD7000+DL.
You can choose the transmitting frequency in the Sonde settings menu which you will find by going to MENU > SETUP
> EQUIPMENT
1. Scroll down to SONDE, press OK and select your desired option.
2. Scroll down to SONDE FREQUENCY. Press OK and use the ▲ and ▼ keys to select the desired transmitting
frequency between: 512Hz, 640Hz, 8kHz and 33kHz.
3. Press OK to confirm the selection and exit to the previous menu.
You can also use the shortcut Fn + F5 to activate or de- activate the sonde.
For more information on locating the sonde and frequency selection, please refer to the documentation supplied with
your cable and pipe locator. The sonde should be used as an estimation tool for assisting with product location.
4.3 Driving the P354 and P356 Crawlers
This section describes driving and retrieving P350 crawlers when used with the manual or powered drum. Although
the principle is the same, the powered drum can retrieve the cable and crawler automatically. You can use the
controller, pendant or keyboard arrows to drive the crawlers.
NOTE: Make sure you have set the correct wheel size before you attempt to drive the crawler.
Pearpoint recommends that you practice driving the crawler on the surface in a safe environment before attempting to
deploy the crawler underground for the first time. In addition to practising driving techniques, it provides a good
opportunity to understand how the system operates.
Analog joystick control
The left hand joystick pod provides intuitive control of the crawler.
The front/back joystick axis controls the acceleration of the crawler.
The left/right axis controls the steering of the P356 crawler.
Pressing down on the joystick will bring the crawler to a stop.
The associated buttons control the elevator position when the powered elevator is fitted.
The P350 joysticks automatically re-set their centralised ‘stop’ position when the stop command is sent. In the
event of unexpected behaviour, return the joystick to the centre position and press to stop the system.
Tilt protection
P350 systems offer automatic TILT protection. By default, this will halt the crawler in hazardous tilting situations, when
its roll first exceeds 35°.The user will be shown a tilt hazard warning, and can restart the crawler movement if
necessary. The user can change this behavior to warn only, without stopping the crawler, or can disable the warning
altogether in the setup menu.
4.4 System stop
You can stop the drive system, including the crawler and the powered drum at any time by pressing the spacebar, Ctrl
+ C or on the controller, EXCEPT when using the Pendant, for safety this is controlled via the Pendant or the
emergency stop button on the drum. Pressing the joystick down will stop the system.
While stopped, the crawler will automatically brake. Press the spacebar, Ctrl + C or to toggle the Brake.
