Indication and warning lights
LCD Display: Displays the 4Hz or 8kHz
signal current that is being delivered
onto the pipe. On startup it confirms the
AC frequency setting and associated
location frequencies. The Tx-25PCM also
displays the battery level on startup.
Output
Voltage Level: Indicates the output
voltage levels. If no LED is lit the output
voltage is below 20V. Do not use
excessive voltage or current, as this may
result in high current density through
small holidays and coating defects.
The may cause minor corrosion if the
transmitter is left on for very long periods.
Voltage Limit: LED on.
Transmitter has reached its 100V output
voltage limit – resistance of the pipe or
ground connection is too high. Check all
connections to correct this problem.
NOTE: If the pipeline being surveyed
has coating that is known to be in good
condition, it is probable that the voltage
warning LED's will illuminate as the
current is increased.
Undesirable voltage on output:
LED flashes. This indicates a high
voltage, such as mains, has been
detected on the output. The unit will
not operate until the cause of the high
voltage has been removed and the
transmitter has been reset by switching
it off, and on again.
Power Limit: System cannot
supply power required to
support transmission at the selected
current. Switch to a lower current setting
until the OK LED illuminates GREEN.
Allow a few seconds to settle between
selections.
Tx Over Temperature: Lights if
temperature exceeds recommended
limits. The transmitter will automatically shut
down. Wait until the transmitter has cooled
down before recommencing operation.
: Lights GREEN to indicate unit is
working correctly
Tx-25PCM only
Power: Indicates power supply
connected
Battery Charging: Indicates when
battery is charging. Lights ORANGE
when battery level is low. Lights Green
when battery is almost charged. When
fully charged the LED will turn off.
Battery Charge Temperature:
Indicates when battery is out of
temperature range for charging.
Tx-1, Tx-5 and Tx-10
transmitters
The PCMx can also be used with a
Radiodetection locating transmitter.
These transmitters do not produce a 4Hz
mapping signal but can be used to either:
• Boost the locate part of the signal when
the PCMx is being used for pipeline
surveys, (for more information see the
PCMx Operation Manual).
• Provide a wider range of locate signals
when the PCMx is being used in
RD8100 mode, as a precision cable
and pipe locator, (for more information
see the RD8100 Operation Manual).

Setting up your
PCMx receiver
Before you begin
IMPORTANT! This guide is intended
to be a quick reference guide. We
recommend you read the full operation
manual before you attempt to operate
the PCMx receiver or transmitters.
Rechargeable battery packs
Your PCMx comes with a Lithium-Ion
battery pack installed. To charge the
battery:
• Connect the battery charger to a
100-240VAC mains supply.
• Connect the battery charger to the
connector on the battery pack.
NOTE: It is not necessary to disconnect
the battery from the receiver for charging.
Switch on the mains supply. The charge
LED provides the battery pack charging
status as follows:
• Red = Charging
• Green = Fully Charged.
• Disconnect the charger once the
battery pack is fully charged
Checking your system
software version
If you wish to check which version
of software is running on your
PCMx, press and hold the
key
when switching on the receiver. This
information may be asked for when
contacting Radiodetection or your local
representative for technical support.
System setup
It is important that you set up the system
according to regional / operational
requirements, and your personal
preferences, before you conduct your first
survey. You can set the system up using
the menus as described below.
The PCMx receiver menu allows you to
select or change system options. Once
entered, the menu is navigated using
the arrow keys. When in the menu, most
on-screen icons will temporarily disappear
and the menu options will appear in the
bottom left-hand corner of the display.
The right arrow enters a submenu and the
left arrow returns to the previous menu.
Note that when browsing the receiver
menu, the
and
keys act as left and
right arrows.
To navigate menus:
1. Press the
key to enter the menu.
2. Use the
or
keys to scroll
through the menu options.
3. Press the
key to enter the option's
submenu.
4. Use the
or
keys to scroll
through the submenu options.
5. Press the
key to confirm a selection
and return to the previous menu.
6. Press the
key to return to the main
operation screen.
NOTE: When you select an option and
press the
key, the option will be
enabled automatically.
