INTRODUCTION
GAUGE PD30 WITH CDI4 DISPLAY
The InteliSENS PD30 Single Axis Laser Scanning Diameter Gauge provides fast, accurate and
repeatable diameter measurements of cables or other objects manufactured in a continuous process.
The PD30 measures objects or cables up to 30 mm in diameter, by a non-contact method. The
gauge contains a single-axis optical scanning system and a processing circuit to produce diameter
and statistical data.
When fitted with the optional CDI4 interface display unit, the InteliSENS PD30 diameter gauge can
operate as a standalone unit.
RS-232, RS-422, RS-485 and Ethernet communication interfaces are installed as standard for
straightforward connection to computers or PLCs. Optional industrial standard communication
interfaces (PROFIBUS, PROFIBNET, EtherNet/IP or WiFi) can be specified for installation at time of
manufacture.
Analogue and pulsed line speed inputs are fitted as standard to provide line speed data to the gauge
for optional PI feedback control and SMFD (Single Measurement Flaw Detection).
User configurable logic inputs are provided as standard to reset gauge measurements and trigger
printing. User configurable relay outputs are provided as standard to signal gauge status, lump and
neck detection and measurements exceeding preset error limits.

Operating temperature

°C
Do not operate the gauge in temperatures outside of the specified range.
Do not install the gauge near high temperature surfaces or objects which may cause it to
overheat.
Operation of the gauge outside the specified temperature range may result in degraded
measurement accuracy, malfunction or damage to the gauge.
Protect from impact
The gauge contains delicate optical and electronic assemblies and must never be dropped or
struck by other objects.
The gauge must be securely mounted by its base to prevent toppling.
Measured objects threaded through the optical gate cavity must be secured against contact
with the optical windows or catching upon the gauge body. For cable production line
applications, Proton Products can supply optional adjustable cable guides for securing the
passage of a cable through the optical gate cavity.
Do not open or disassemble
The gauge contains no user serviceable components.
Loosening the gauge screws or removing its cover will invalidate the product warranty.
Periodic maintenance
The physical condition of the gauge, optional CDI4 interface display unit and connecting
cables should be checked periodically; if any damage is suspected, then the unit should be
taken out of service for inspection and repair or replacement of damaged parts.
Optical windows
Do not allow smoke, water, steam, dust or other debris to come into contact with any of the
optical windows.
Obstruction of the optical windows may degrade measurement accuracy or inhibit
measurement.
If any optical window appears to be damaged or misaligned, then the unit should be taken out
of service for repair.
If any optical window requires cleaning, then refer to the cleaning procedure detailed in this
manual to minimise the risk of scratching the windows.

Page 16 of 68
Proton Products InteliSENS PD30 Instruction Manual (Issue 1a)
OPTICAL WINDOW CLEANING PROCEDURE
The optical windows are manufactured from anti-reflection coated optical glass; they must be
treated with the same level of care as a high-performance camera lens.
Before inspecting or cleaning the optical windows, ensure that the gauge is powered
off and no light is emitted.
Required items
Notes
Small blower brush
Such as the type used to remove dust from camera lenses.
Lens cleaning tissues or
micro-fibre lens cleaning cloth
Do NOT use facial tissues as these can scratch delicate optics.
Lens cleaning solution
Such as the type specified for cleaning camera lenses.
1. Use the small blower brush to remove any visible dust on the optical window.
2. Apply a few drops of lens cleaning solution to a fresh lens cleaning tissue or a clean micro-
fibre lens cleaning cloth.
3. Gently wipe the optical window from the centre outwards; apply only light pressure to the
tissue or cloth when wiping the optical window.
4. Repeat as necessary with fresh tissues or a clean section of cloth until the optical window is
clean and free of all smears and smudges.
INSTALLATION SEQUENCE
Unpack the gauge and check for missing accessories and shipping damage.
Mechanical installation:
1. Mount the gauge securely on a user supplied platform using the four mounting brackets.
Electrical installation:
1. Install earth connections.
2. Install optional CDI4 interface display unit.
3. Depending on the model, install either an AC power cable or DC power supply (such as an
optional Proton Products PSU-UNI, PSU-BOB or PSU-CAN power supply).
4. Install interface connections (RS-232, RS-422/485, Ethernet or optional PROFIBUS,
EtherNet/IP or WiFi antenna).
5. Install speed input (analogue or pulse).
6. Install optional electrical interfaces (Logic inputs, Relay outputs, Analogue outputs, PI
feedback controller connections) using the optional Proton Products PSU-BOB breakout box
or terminal strip.
7. Configure the gauge either via an optional CDI4 interface display unit or any of the above
interfaces.

MECHANICAL INSTALLATION
GAUGE HEAD DIMENSIONS:PD30
INSTALLATION NOTES:
Do not open the gauge or loosen the cover screws.
Do not overtighten the fixing screws.
Do not use fixing screws that are too short or long. The correct screws [M5 by 16] are supplied
with the gauge head for mounting it to the HST3 height stand which has a thickness of 8mm. If a
stand of different thickness is used then the screw length supplied may not be suitable.
Do not place in a position close to a hot surface.
Do not allow the cable being measured to touch the gauge head.
If a large cable is being measured then ensure that it is supported so that the cable end does not
catch on the gauge.
Ensure that the cable alignment is perpendicular to the face of the gauge with the least error
practically possible, an angle error of one degree gives a measurement error of 0.013%, at two
degrees this becomes 0.05%.
ELECTRICAL INSTALLATION
Earth connection
Connector type: M5 bolt
An earth wire of at least 6mm2must be attached via a crimp on ring terminal to the dedicated
M5 earth bolt on the case of the gauge.
Do not rely on the mounting bolts to provide a reliable earth path.
If a height stand is used then it must also be earthed via its own dedicated earth wire.
All earth wires should be kept as short as practical.
Shielded Cables
Use shielded cable for all signal connections.
Ensure that all cable shields are correctly clamped and electrically connected to their
connectors and metal connector shells at both ends.

Page 18 of 68
Proton Products InteliSENS PD30 Instruction Manual (Issue 1a)
Ensure that the shields of cables connecting to the end user’s equipment are clamped to
earth at their destination.
Optional CDI4 interface display unit installation
The CDI4 interface display unit is a recommended optional accessory with the following features:
Menu based user interface for configuring the gauge and displaying measurements and error
messages.
Two versions of the CDI4 interface display are available: one version that mounts directly on
the gauge body and one version that can be connected remotely via a CAN-bus extension
cable.
The remote CDI4 interface display unit can also power DC powered gauges through a CAN-
bus port connected power supply.
Installing a CDI4 display unit to PD30 gauge head:
1
Unscrew the four screws and remove the CDI4
port blanking plate.
Store the blanking plate and four countersunk
screws for future use.
2
Align the CDI4 connector mating key with
the port socket and insert.
Secure the CDI4 unit with four spring
washers and M4 cap head screws.
Installing a remote CDI4 interface display unit:
1. Connect the remote CDI4 interface display unit to the CAN/POWER connector using a CAN-
bus extension cable.
2. Connect an optional PSU-CAN mains power supply unit to the second CAN-bus port on the
remote CDI4 interface display unit.
