4. OPERATION
Familiarise yourself with all of the rules for the safe operation of this equipment as described in
section 3 RULES FOR SAFE OPERATION.
4.1. TURNING ON
If powered from 24.0VDC power supply via
the VEXT connection the unit will turn on
automatically as soon as power is applied. If
powered from batteries simply press and hold
the control button until the COMPANY LOGO
appears on the display and then release, this
takes approximately 5 seconds.
The COMPANY LOGO will be displayed for 5
seconds as shown by the COUNTDOWN
INDICATOR located at the top left-hand side
of the display.
When the COUNTDOWN INDICATOR reaches
zero or the CONTROL BUTTON is pressed, the
next screen will appear.
The next screen shows the PRODUCT LOGO
and firmware version at the bottom of the
screen.
The next screen shows the current system
date and time. If the date and time are blank
as shown then the date and time will require
setting via the menu system or RS485
MODBUS serial interface.
The unit now enters STABILISATION. During
STABILISATION the unit will initialise the
detection filters and acquire the ambient
noise level of the pipeline.
Once STABILISATION is complete the unit
will enter LISTENING mode. In LISTENING
mode, the display will be switched off and the
LEDs will flash every 5 seconds to indicate
that the unit is active. See section 4.2
LISTENING for more information.
