1. Use of this Document
This user guide is intended for persons familiar with the use of construction plant undertaking
lifting operations.
WARNING denotes information about particular risks which may be
generated by certain applications, by using certain fittings, and about
additional protective measures which are necessary for such applications.
HAZARD Actions that can lead to serious injury or death
2. Notices
Adjustment by unauthorised persons will invalidate any warranty or
certification supplied. If an error condition is displayed which cannot be
rectified using this guide, STOP any operation, seek authorised service
immediately, and do not continue the operation until the fault has been
remedied.

3. System Identification
The PME system provides an envelope safety function.
All safety functions are achieved through real time monitoring of some or all of
the machine’s moving parts (booms, other articulations, turret etc) and its
environment (ground pitch and inclination, load etc) and actively determining
the safety of the current operation where appropriate limits have been set.
The Machine Envelope Monitoring function has a single class
•Machine Envelope Controllers (MEC) prevent movements that would
bring parts of the machine into hazardous areas.
During operation, indicators are displayed on the screen to clearly identify the
function supported by your PME300. Functions may not be available i.e. when
envelope monitoring is switched off, if this is the case a cross will be painted
over the function icon.
PME300 is NOT a height limiting device

4. Operating, and Hazard Situation, Recommendations
Operating Recommendations
When using envelope monitoring:
•When setting slew restriction, make sure
any implement/tool attached is in its least
favourable position
•Check for correct operation once the
restriction has been set
•Reduce operating speed
•Do not move the equipment quickly when
close to a restriction
•Do not operate the machine in a reckless
manner
•Do not travel with a restriction set
•Reset the slew restriction if the machine is
relocated
Hazard Situation Recommendations
In a limit hazard state:
•Return the control levers to neutral once a
limit has been reached, if appropriate
•Operate the machine at a slow speed
•Do not travel

4.1.MEC Override
The system can optionally be fitted with a key operated master override
switch. To access the master override switch, a tamper detection device
must be broken and the operation of this switch will be automatically logged.
Turning the switch to the override position will allow normal operation of any
of the hydraulic services regardless of safety status. When the system is in
override:
•the external alarm (if fitted) will be active
•the beacon (if fitted) will be off
•the RED LED will flash
•an ‘In Override’ message will appear on the display indicating that the
machine limiting is overridden.
The override state will automatically return to normal operating mode after 30
minutes (default value), regardless of the system status. The master override
key switch must be cycled to put the system back into override.
The master override key switch should only be used if the system is not
operational due to a fault and the machine needs to be moved due to its
location presenting a hazard.

5. Operating Instructions
5.1.Power Up
The PME system automatically powers up
when the machine ignition is switched on. The
in-cab display incorporates a 4.3” high
resolution LCD display and is controlled with
three buttons at each side. Three status LEDs
and an internal alarm provide further
information. The display is secured to the
machine using a flexible ball mounting allowing
easy adjustment for personal viewing
preference.
1. On starting up, the system will perform a self-test. All LEDs will flash; the internal display
alarm and the external alarm (if fitted) will sound momentarily.
2. The operator will be asked to review the system’s safety features.
(Note: older system types may not display this screen –skip to step 4 if it does not appear)
Individual safety features may be disabled or re-enabled, if appropriate for the current job
and work site. For example, if the work site has no adjacent hazards, the operator may
disable the slew limiter function.
•Each safety feature is initially set/enabled as it was set before the last power-down.
•The operator is responsible for verifying that the safety features are enabled
appropriately for the job/work site.
•If the slew limiter function is enabled, the operator is responsible for checking that the
movement limits are correctly configured:
•See section 7.1 for configuring Slew Limits

562300-000, Issue 1.4 March 2023
Page 10 of 38
•If the system is fitted with a supervisor key switch (see section 5.4), this key must be
turned to the SET position to disable/enable the Slew Limiter function.
•If a safety function is unavailable –for example due to a system or sensor fault –this
will be made apparent to the operator from this screen.
3. The operator must press Start to:
•Confirm that the safety features are set as required for the job/work site;
•Confirm that any unavailable safety features are understood, and not required for
the job/work site.
Pressing Start activates the operating mode, at which point the GREEN LED will light.
4. The system can be configured to only allow access via a User Login code and will prompt
for a code to be entered before use (see section 5.3 for further details).
If the RED LED is lit, a fault has been detected, halt any operation,
seek authorised service immediately and do not continue operation
until the fault has been remedied.
