1. GENERAL DESCRIPTION
The ID5001P (Passive) pig signaller is a fully ATEX and IECEx certified, Exd flameproof, non-
intrusive, pig signaller which detects, signals, and logs the passage of pigs at critical points along
a pipeline both on land and offshore.
The unit uses Passive (listening) techniques to detect pig passage events. Events are signalled
as they occur via a 3” graphical LCD display and high brightness LEDs positioned above and
below the display. Events can also be signalled remotely using several optional outputs.
The unit logs the time and date of up to 99 events which can be viewed at any point using the
local display. The user can turn the unit ON and OFF as well as modify several settings using a
single control button and intuitive menu system.
The unit has two basic parts as shown below. The sensor is permanently connected to the main
housing via a cable and can be quickly and easily attached to the pipeline using ratchet straps
or steel banding. The main housing contains all electronics, batteries (if fitted), display and the
control button and can be mounted onto the pipeline using a mounting plate and straps in a
similar fashion to the sensor or mounted on a wall or post.

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.

4.2. LISTENING
While in LISTENING mode the unit continuously monitors the acoustic energy produced by the
pipeline as it waits for a pig passage to occur. The unit is configured to recognize the unique
sound signature produced by a pig as it passes the sensor. The unit uses the algorithm described
in section 4.4 DETECTION ALGORITHM to detect a pig passage.
While in LISTENING mode the display will be off and the LEDs above and below the display will
flash every five seconds to indicate that the unit is active. The relay and current loop outputs
will be in LISTENING state.
There are two things that may cause the display to change:
CONTROL BUTTON – If the control button is pressed the unit will enter the MENU system.
The menu system is described in section 4.5 SINGLE BUTTON MENU INTERFACE.
PIG APPROACH – If the unit detects a possible pig approaching
the sensor then the display will show a PIG APPROACH message
as shown. From this point the unit will continue running through
the detection algorithm until either the approach is cancelled, in
which case the display shall turn off, or it will signal pig detected
as per section 4.3 DETECTION.
4.3. DETECTION
When a pig is detected the display will show a PIG DETECTED
message including the time and date of the event as shown. The
LEDs above and below the display will flash every second and the
relay and current loop will be in the DETECTION state. The time
and date of the pig passage are stored in internal memory and
can be viewed later using the menu interface.
The unit will remain in the DETECTION state for the length of time defined by the OUTPUT DELAY
before returning to LISTENING mode. The OUTPUT DELAY can be bypassed by pressing the
CONTROL BUTTON.
OUTPUT DELAY – The OUTPUT DELAY controls how long the unit will signal an event for. Usually
it will be configured to give the pig enough time to get out of range of the sensor after it has
been detected to avoid re-trigger. When dealing with pig trains, the expected pig speed and
separation should be used to configure a suitable value for the OUTPUT DELAY such that the unit
will not detect the same pig twice but will enter LISTENING mode in time to detect the next pig.
LATCHED DETECTION – If the OUTPUT DELAY HH (hours) field
is set to 99 then when an EVENT occurs the unit will LATCH in
DETECTION mode showing the EVENT information and flashing
the LEDs every 1 second. To begin LISTENING again the CONTROL
BUTTON must be pressed or the detection reset using the serial
interface.

4.5. SINGLE BUTTON MENU INTERFACE
While LISTENING, the control button can be pressed to enter the menu interface. From the menu
system the user can configure several parameters which are discussed in this section.
When any menu screen is loaded the cursor will initially be located at the home position at the
top right corner next to the page number to indicate that the BACK action will occur when the
countdown expires.
Pressing the control button causes the CURSOR to move down to the next menu item and the
COUNTDOWN INDICATOR will be reset to 5. Once the CURSOR is pointing at the desired item
the user simply allows the COUNTDOWN INDICATOR to reach 0 and the selected item will be
executed. This simple behaviour is used throughout the menu interface to modify settings and
interact with the unit.
If the active menu has multiple pages, as indicated in the top right-hand corner then when the
last item is reached the next button press will load the next page and the cursor will return to
the home position. When the end of the last page is reached then the unit will loop back to page
1 of the active menu.
If the selected item is a menu then when the countdown expires the new menu is loaded,
otherwise if the item is an editable field then the display will go into edit mode to allow the value
to be changed. In edit mode the part of the field actively being edited is enclosed in a box to
highlight it. Some parameters will provide additional information on screen while editing such as
min and max values. All parameters are incremented by pressing the CONTROL BUTTON until
they are at the desired value. Allowing the COUNTDOWN INDICATOR to reach 0 either selects
the next editable digit in the field if there is one, otherwise edit mode will exit and the new value
will be saved.
If while editing a parameter value you wish to cancel the edit operation, then press and hold the
CONTROL BUTTON until the cursor returns to the home position.
If an item was selected accidentally then simply press and hold the CONTROL BUTTON until the
cursor returns to the home position or allow the COUNTDOWN INDICATOR to reach 0 without
pressing the CONTROL BUTTON.
The menu system is designed so that the unit will always return to LISTENING mode if the
CONTROL BUTTON is left released for a long enough time.
Below is the typical layout of a menu screen:

4.5.6. DETECT CONFIG MENU
ADJUSTING THESE PARAMETERS WITHOUT FIRST
CONSULTING ONLINE ELECTRONICS LTD MAY CAUSE
THE UNIT TO MISS PIG PASSAGES OR GIVE FALSE
DETECTIONS.
The DETECT CONFIG MENU allows the user to configure the
detection parameters for the unit. This menu consists of
three pages as shown.
HIGH THRESHOLD – The Difference Level (DL) must
exceed this threshold before the unit will consider a possible
pig approach. (0 – 65535)
LOW THRESHOLD – The Difference Level (DL) must fall
below this threshold after being above High Threshold (HT)
to trigger a pig detection. (0 – 65535)
DELTA TIME – The length of time the Difference Level (DL)
must be above the Low Threshold (LT) after exceeding the
High Threshold (HT) before the unit will indicate a detection.
If the time does not exceed this value, then the pig approach
will be cancelled. (1 – 100 seconds)
AV VALUE TIME – The time period the Power In-Band (PIB)
is averaged over to calculate the Average Value (AV).
(1 – 100 seconds)
AV NOISE TIME – The time period the Power In-Band (PIB)
is averaged over to calculate the Average Noise (AN).
(1 – 100 minutes)
AV NOISE OVER – The value of Average Noise (AN) can be over ridden by the user, if this value
is set to zero then the calculated Average Noise (AN) will be used. (0 – 65535)
NUM AVERAGES – The number of samples that will be averaged to calculate the Power In-Band
(PIB). Increasing this value will smooth the resultant PIB output waveform at the expense of
increased processing time to compute the FFTs. (1 – 50)
UPPER FREQ BIN – The highest frequency bin to be included in the Power In-Band (PIB).
200Hz/bin (1 – 100)
LOWER FREQ BIN – The lowest frequency bin to be included in the Power In-Band (PIB).
200Hz/bin (1 – 100)
HARDWARE GAIN – The hardware gain configuration. (1 – 4)
SENSOR GAIN – The sensor gain level. (1 – 12000)
HP FILTER – Enables or disables the hardware high pass filter stage.
RESET TO DEFAULTS – Selecting this item will reset all detection parameters to their default
values. This option requires the user to confirm before it is actioned.

4.6. RS485 SERIAL INTERFACE
Communication to the ID5001P, via the RS485 interface, makes use of MODBUS RTU protocol.
All the parameters available in the ID5001P menu system can also be accessed via the MODBUS
interface. The serial interface should be configured as follows:
9600 baud, 8 data bits, 1 stop bit, no parity
⚠WARNING: Care should be taken when remotely controlling/configuring the unit via the
MODBUS interface as values set intentionally, or unintentionally, will immediately affect the
operation of the ID5001P. E.g. enabling relay inversion, although a useful test, will cause the
relay to switch and signal an event when no event is active.
If the ID5001P is powered from batteries, and LOW POWER MODE is enabled, then the RS485
interface will be disabled. If you require to use the RS485 interface while powered from batteries
then LOW power mode must be disabled, although be aware that this will significantly reduce
the battery lifetime.

5. INSTALLATION
⚠WARNING: The Special Conditions for Safe Use as detailed in section 10 CERTIFICATION
APPENDIX must be followed at all times.
Normally the unit is used to confirm whether or not a pig has passed a known point of interest
on a pipeline such as a bend or valve. The unit should be mounted approximately 5m after the
point of interest and a test run completed to confirm successful installation and reliable detection.
If the main housing is exposed to direct sunshine, then it is recommended that a sunshade is
installed to prevent unnecessary heating of the unit which may shorten the lifespan of the
equipment. See sections 5.5 SUNSHADE POST MOUNTING and 5.6 SUNSHADE PIPELINE
MOUNTING.
5.1. MAIN HOUSING MOUNTING PLATE
The unit is supplied with a mounting plate as shown
which is suitable for use with ratchet straps or steel
banding and for mounting the unit onto pipelines,
posts and walls.
If the unit is post mounted, then 4x M8x120 coach
bolts should be fitted as per 5.2 MAIN HOUSING POST
MOUNTING prior to attaching the mounting plate.
The mounting plate is attached to the main housing as
shown using 2x M8x16 bolts / 2x M8 spring washers /
2x M8 plain washers / mounting plate / 2x M8x5
spacers / main electronics housing.
5.2. MAIN HOUSING POST MOUNTING
The post mounted unit is supplied with a post mounting assembly as
shown.
1. Prior to fitting the mounting plate as per 5.1 MAIN HOUSING
MOUNTING PLATE pass the 4x M8x120 coach bolts through the
mounting plate.
2. Hold the assembly in position on the post and secure using 4x M8
nuts / 4x M8 washers / post mount clamp / post / mounting plate
/ 4x M8x120 coach bolts as shown (view from above).
3. If equipotential bonding, or earthing is required, then the M4
threads around the perimeter of the display endcap may be used.

5.3. MAIN HOUSING PIPELINE MOUNTING
The pipeline mounted unit is supplied with a set of ratchet
straps or steel banding as shown.
1. If the pipeline surface temperature is expected to exceed
the maximum permitted ambient temperature for the
enclosure as per the tables in the Special Conditions for
Safe Use within section 10 CERTIFICATION APPENDIX then
the housing must NOT be fitted on the pipeline.
2. Ensure the mounting plate is securely fitted to the housing
as per 5.1 MAIN HOUSING MOUNTING PLATE.
3. Temporarily place the unit at the chosen location to ensure
that the unit sits in place without rocking excessively.
4. Thread 2x loops of banding through the slots provided in
the mounting plate as shown and then following the
instructions provided with the banding gradually tighten the banding until the unit is held
firmly. Do not use excessive force.
5. If equipotential bonding, or earthing is required, then the M4 threads around the perimeter
of the display endcap may be used.
5.4. SENSOR MOUNTING
The sensor is supplied with a mounting
plate, a mounting stud, a PEEK insulator (if
required) and a length of mounting band.
1. If the pipeline surface temperature is
expected to exceed +85°C then the
sensor must be fitted on the lower half
of the pipeline as shown to minimise
convection heating and a PEEK
insulator must be fitted to thermally
insulate the sensor from the pipeline.
Online Electronics should be contacted
for further guidance. Do NOT exceed 3
N·m tightening torque if using the PEEK
insulator or the threads may be damaged.
2. Pass the mounting stud or insulator (if required) through the ø6mm hole in the mounting
band and then screw into the mounting plate approximately 4 full turns. Do not tighten
further at this point.
3. Loop the mounting band around the pipeline and then following the instructions provided
with the banding gradually tighten the banding until the mounting assembly is held firmly.
Do not use excessive force.
4. Ensure that the mounting plate is positioned to form a cross with the mounting band and
the mounting band has been firmly tightened before fully tightening the mounting stud into
the mounting plate using a 21mm AF wrench or the insulator (if required) using a 15mm AF
wrench. Do NOT exceed 3 N·m tightening torque if using the PEEK insulator or the threads
may be damaged. It should not be possible to move the mounting plate at this point.
5. Attach the ID5001P sensor to the mounting stud tightening using a 1” AF wrench. Do NOT
exceed 3 N·m tightening torque if using the PEEK insulator or the threads may be damaged.
