DURING NORMAL OPERATION THE SAFE WORKING LOAD OF A CRANE SHOULD
NOT BE EXCEEDED. THEREFORE THE WARNING OF OVERLOAD SHOULD NOT
BE USED AS A NORMAL OPERATING FACILITY. IT SHOULD BE NOTED THAT
CERTAIN STATUTORY REQUIREMENTS DO NOT PERMIT THE SAFE WORKING
LOAD TO BE EXCEEDED EXCEPT FOR THE PURPOSE OF TESTING.
THIS RATED CAPACITY INDICATOR / CONTROLLER (RCI, RCC) IS NOT SUITABLE
FOR USE IN EXPLOSIVE ATMOSPHERES. ADJUSTMENT BY UNAUTHORISED
PERSONS WILL INVALIDATE ANY WARRANTY OR CERTIFICATION SUPPLIED. IF
A PROBLEM ARISES WHICH CANNOT BE RECTIFIED USING THIS GUIDE,
AUTHORISED SERVICE SHOULD BE SOUGHT.
THIS DEVICE IS CERTIFIED TO MEET CURRENT UK & EC SAFETY REGULATIONS
FOR LIFTING OPERATIONS.
Any alterations or modifications to machine components which affect this system and any
system component failure must be reported to Prolec Ltd or via the machine convertor/
service agreement holder. This manual must be kept with the product and be passed on
to any subsequent user of the product.
Whilst every effort has been made to ensure the accuracy of the information supplied in
this manual, Prolec Ltd cannot be held responsible for any errors or omissions.

This user guide is intended for persons familiar with the use of construction plant under-
taking lifting operations.
2 Notices
Adjustment by unauthorised persons will invalidate any warranty or certifi-
cation supplied. If an error condition is displayed which cannot be recti-
fied using this guide, halt any operation, seek authorised service immedi-
ately and do not continue operation until the fault has been remedied.
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.

3 System Identification
The PME system provides two primary safety functions
1. Lifting Stability
2. Machine Envelope Monitoring
Both safety functions are achieved through real time monitoring 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 appropri-
ate limits have been set.
The Lifting Stability function falls into two sub classes
Rated capacity indictors (RCI) warn of potential instability when
the machine is involved in lifting operations. Any motion which re-
duces the safe working load will not be inhibited at any time.
Rated capacity controllers (RCC) prevent instability when the ma-
chine is involved in lifting operations. This is achieved by hydrauli-
cally stopping unsafe movements of the machine which could
cause the machine to tip.
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, most nota-
bly height restrictions when working under overhead wires.
During operation the indicators on the left are displayed on the screen
to clearly identify the function supported by your PME500. Functions
may not be available i.e. when in non-lifting mode or when envelope
monitoring is switched off, if this is the case a cross will be painted over
the relevant function icon.
Combinations of these functions may be present, it is essential that the
functions of the system installed are identified and understood.

4 Operating and Hazard Situation Recommendations
4.1 MEC Override
The system can optionally be fitted with a key operated master override
switch. Turning the switch to the override position will allow normal operation
of any of the hydraulic services regardless of safety status. When the unit is
in override the external alarms will stay active, and the beacon (if fitted) will
indicate that the machine is overridden, the red LED will flash and an ‘In
Override’ message will appear on the display.
Operating Recommendations
When using envelope monitoring:
When setting a slew restriction,
make sure any implement attached
is in its least favourable position
Check for correct operation once the
restriction or restriction have been set
Reduce operating speed
Do not move the equipment quickly
when close to a restriction
Do not operate the machine in a
reckless manor
Do not travel with a restriction set
Do not travel
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
When operating the machine as a
crane:
Ensure Lift Mode is selected dur-
ing lifting operations
Operate the machine at a sensible
speed
Take extra care when travelling
with a load attached
Do not operate the machine in a
reckless manner
