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 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 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
reduces 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
hydraulically 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 PME200. 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
Operating Recommendations
When using envelope monitoring:
When setting a slew and or height restriction, make sure any implement attached is
in its least favourable position
Check for correct operation once the restriction or restrictions 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
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 master override key switch. Turning
the key to the override position will allow normal operation of the hydraulic
services regardless of safety status. When the system is in override, the external alarm (if fitted) will be active, and the beacon (if fitted) will be off, the
RED LED will flash and 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 safety system is
not operational due to a fault and the machine needs to be moved due to its location presenting a hazard. The override status is recorded in the system data log. To access the
override key switch an anti tamper seal may need to be broken.

5 Operating Instructions
5.1 Power Up
The PME system automatically powers up when the ignition is switched to on. The in-cab
display 4.3” high resolution LCD display and is controlled with three buttons at each side.
Three status LEDs and an internal alarm provide further indication.
The system will perform a self check at start up:
1. All LEDs will flash, the internal alarm and the external alarm (if fitted) will sound and
the system will perform a self test.
2. Once the self test is complete, a safety warning message will be displayed, pressing
any button activates the operating mode, the GREEN LED will light. Any previous
limit or limits set will be enabled.
3. The system is now ready for use unless the user login feature has been enabled,
see section 5.3.
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.
The display is secured to the machine using a flexible ball mounting allowing easy adjustment for personal viewing preference.

7 Rated Capacity Indicator / Controller
7.1 Introduction
The PME200 RCI / RCC has been designed to meet European requirements for the provision of rated capacity indicators. PME200 ensures that the maximum lifting capacity
over the range of a machine working envelope can be utilised. The system will always
start up in Lifting Mode. See section 4 for operating advice when using construction plant
as a crane. The Lifting Mode feature can be used in conjunction with envelope monitoring, see section 8. In this mode, the beacon (if fitted) will indicate that the Lifting Mode
functionality is active.
1. Lifting point radius
4. Safe directional
indicators
8. Load On Hook
1. Lift point radius is the horizontal distance in metres from the slew centre line to the
lifting point.
2. Current lifting duty in use.
3. Current lift point in use.
4. Safe Directional indicators. The triangles on both sides of each piece of equipment
and slew arrows indicate if it is safe GREEN, or unsafe RED to move the relevant
articulation and direction in that direction under overload envelope limits. A triangle
with a red border indicates that the articulation is limited by hydraulic capacity and
not by machine stability.
5. RCI / RCC - MEC indicators (see section 3)
6. Maximum Safe Working Load (SWL) for the current lifting point height and radius
combination. The value is given in metric tonnes.
7. SWL percentage bar graph indicating the percentage of the current load to the
maximum available safe working load.
8. Load on Hook (LOH) shows the current load in tonnes suspended from the current
lifting point.
2. Current Duty
7. SWL percentage 5. RCI / RCC indicators
3. Current Lifting point
6. Maximum Safe
Working Load
5. MEI / MEC
indicators
The SWL as displayed assumes that the load is suspended directly below the
lifting point. The weight of the tool or tools, if fitted, (e.g. Bucket , quick hitch etc)
are accounted for in the SWL and LOH values if they were taken into consideration
when the system was calibrated. The bucket cylinder and control linkage is
assumed to be present.

562200-000, Issue 1.2, December 2015
7.2 Operation within the Safe Working Load
With the Lifting Mode active, the current lifting point radius and the
maximum safe working load for that radius are shown.
If the load is less than 95% of the
maximum safe working load
The load capacity indicator will be
green
The green LED will be lit
7.3 Approach to Overload
With the Lifting Mode active, if the load is between 95% and 104% of
the maximum safe working load the system will warn the machine is
close to the lifting capacity at the current height and radius. The system
indicates an approach to overload condition via an internal alarm in conjunction with visual indicators on the display - no motion is cut.
If the load is greater than 95% of the
maximum safe working load.
The load capacity indicator will be
amber
The amber LED will be lit
The internal alarm will sound
The message shown here will be
displayed.
In the event of an approach to overload or an overload condition, the lifting
point should only be moved in a direction that increases the safe working
load. See section 4 for further information.
18 of 62
562200-000, Issue 1.2, December 2015
7.4 Stability Indication Overload
With the Lifting Mode active, if the load is greater than 105% of the maximum
safe working load the system will warn the machine is close to the lifting capacity
at the current height and radius. The system indicates an overload condition via
internal and external alarms in conjunction with visual indicators on the display no motion is cut.
If the load is greater than 105% of the
maximum safe working load
The load capacity indicator will be red
The red LED will flash
The internal and external alarm will
sound
The message shown here will be
displayed
Unsafe motion is indicated by RED
arrows, safe motion is indicated by
GREEN arrows
7.4.1 Hydraulic Limit Indication
If a particular lift is limited by hydraulic capacity rather than stability, the directional indicator on the articulation in question will have a RED border. Hydraulic limitation is more
likely to occur at short radii. The system indicates a hydraulic limitation condition via
internal and external alarms in conjunction with visual indicators on the display - no motion is cut.
In the event of an approach to overload or an overload condition, the lifting
point should only be moved in a direction that increases the safe working
load. See section 4 for further information.
19 of 62
562200-000, Issue 1.2, December 2015
7.5 Stability Control Overload
Where an overload condition occurs the machine hydraulics will be locked to pre-
vent any further dangerous movements. Only those movements that allow safer
operation remain active. The radius cannot be increased and the load cannot be
raised. The internal and external alarms will sound in conjunction with visual indicators on the display.
If the load is greater than 105% of the
maximum safe working load
The load capacity indicator will be red
The red LED will flash
The internal and external alarm will
sound
The message shown here will be
displayed
Motion control of the machine will
operate, motion cut is indicated by
RED arrows, safe motion is indicated
by GREEN arrows
7.5.1 Hydraulic Limitation Control
The system will cut motion to the appropriate articulation in a hydraulic limit state and indicate this via internal and external alarms in conjunction with visual indicators on the display.
Where an overload condition occurs the machine
hydraulics will be locked to prevent any further
dangerous movements. Only those movements
that allow safer operation remain active. The radius cannot be increased and the load cannot be
raised.
After three seconds a soft override will become available, see section 7.6.1
In the event of an approach to overload or an overload condition, the lifting
point should only be moved in a direction that increases the safe working
load. See section 4 for further information.

7.6 Overload / Hydraulic Limitation Control Override
7.6.1 Soft Override
After three seconds a soft override button may replace the Lifting Mode button. If soft override is utilised, the machine hydraulics will be re-enabled. However, the external alarm will stay active, the red LED will flash, and the beacon
(if fitted) will switch off. Once the alarm condition has been corrected the RCC
will automatically clear the override request and revert to normal operation.
Soft override
7.6.2 Master Override key Switch
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. See section 4.1 for further details.

8 Envelope Monitoring
PME200 can be configured for Machine Envelope Indication (MEI) or Machine
Envelope Control (MEC). MEI will give a warning only, MEC will warn, and
prevent equipment motion. MEC is achieved by interacting with the machines
hydraulics, this allows motion to be cut to any section of equipment that has
reached a restriction but allow other sections to operate
unhindered unless they too reach the set restriction.
PME200 can monitor the highest, furthest, nearest and lowest part of the machine. When
setting a limit, either by entering a known value or by positioning the machine at the desired limit, make sure any implement attached is in its least favourable position as the
system is unaware of any implement fitted unless listed in Tool Selection, see section 6.1.
Height Limiting
Max Radius Limiting

16 Taking Product out of Operation
Prolec Limited is committed to complying with the upcoming European
Directive of RoHS (Restriction of Certain Hazardous Substances) and
WEEE (Waste from Electrical and Electronic Equipment). PME is subject to the WEEE directive, therefore PME or any component must be
returned to Prolec Ltd for correct disposal or recycling.
The display and safety controller are fitted with internal batteries and
must not be disposed of in landfill.
17 Service and Repair
PME has very few user serviceable parts. The safety controller has internal fuses that, in
the event of a blown fuse, can be replaced. The service section describes daily, monthly
and yearly checks that must be carried out to ensure safe operation of the system.
17.1 Maintenance Review
Due to nature of the PME system operating environment, changes in usage can occur.
Prolec Ltd must be notified of any changes in the pattern of use of the system for consideration.
Any alterations or modifications to machine components which affect the system must be
reported to Prolec Ltd or via the service agreement holder.
To aid in the use of PME, all appropriate technical bulletins relating to PME are to be assessed and implemented as appropriate. This information is available from Prolec Ltd.
Prolec Ltd must be informed of any Prolec system component failure. Be it directly or via
the service agreement holder.
Technical consultation is available to the user, contact Prolec Ltd or the service agreement holder.
