System Identification
The PMERail Ultra 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 appropriate limits have been set.
The Lifting Stability function falls into a single class

Rated Capacity Controllers (RCC) prevent instability when the machine 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 notably height restrictions when working under Overhead Line Equipment and in an Adjacent Line Open situation.

4.1 RCC - MEC Override
The system is 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 controlled by PMERAIL regardless of safety status. When the system is
in override, the external alarms will stay active, the amber and blue lamps will
be off and the red LED will flash along with an ‘In Override’ message will on
the display.
The 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.
The override status will be recorded in the system data logger.

7.2 Operation within the Safe Working Load
With Lifting Mode active, the Load on Hook, current lifting point, current duty, 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 Barred Duties, warnings and Interlocks
A duty can be denied entry by locking certain machine hydraulic services if there is insufficient lifting capacity in that duty. For Lift and carry duties only, no motion cut will occur.
Travel and axle lock interlocks can operate automatically to ensure the stability of the machine during use, see Appendix 2.
7.4 Approach to Overload
With Lifting Mode active, if the load is greater than 95% of the maximum safe working
load, the system will warn the machine is approaching the lifting capacity at the current
height and radius.
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.

562600-000, Issue1.0, March 2014
7.5 Stability Overload Control
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, all slewing is prevented. 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 via internal and
external alarms in conjunction with visual indicators on the display. If a particular lift is limited by
hydraulic capacity rather than stability, the maximum safe working load will be shown in RED. Hydraulic limitation is more likely to occur at short
radii.
*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 if the supervisor keyswitch is in the SET position, see sections 5.5 and 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.

7.8 Lifting Duty Safety Factors
The maximum safe working load will appear at the top right of the screen and is stated in
TONNES. This maximum load is for the currently active lifting duty / lifting point. Lifting
duties are automatically selected using a combination of chassis status, axle lock status,
slew angle, chassis angle and switch inputs. Altering the duty will not affect the current
lifting point selected, see section 7.7.1.
If a particular lift is limited by hydraulic capacity (87% of Main Relief Valve pressure)
rather than stability, the maximum safe working load will be shown in RED. The maximum
load is stated as a percentage of the ‘tipping load’ and in a standard installation will conform to the table shown below :
Lifting regime
Safety factor
Notes
Road
75%
All road lifting duties regardless of chassis angles and oscillating axle lock
status.
Network Rail
67%
Lift and carry - oscillating axle unlocked
Network Rail
75% or 90%
Static lift - oscillating axle locked. The maximum load will be either 90% of
a load necessary to totally unload a single rail wheel, or 75% of a load
necessary to totally unload two rail wheels - whichever is the lowest.
Tandem Lifting
67% of the current
safety factor
If ‘Tandem Lifting’ mode is selected all duties will revert to this safety factor
regardless of bogie position, chassis angle or oscillating axle lock status.
LUL
75%
All LUL lifting duties regardless of chassis angles and oscillating axle lock
status.

7.10 Safe Working Area Indication
Safe working area indication displays in real time the where a load can be safely moved
using the plan view. This feature will be available if it has been activated at calibration.
With Safe Working Indication ON:
The Green area indicates the safe zone
The Hatched area indicates the hazard
zone
Any green area is safe and any hatched area is unsafe. The hatched area uses the LOH
value and the SWL value for all slew based duties to calculate the green and hatched
area. If a Virtual slew wall (section 8.2) has been set then this limit will be incorporated
into the hatched area.
This feature does not indicate duties automatically switched using proximity switches
such as extending sections or stabilisers.

Envelope Monitoring
PMERail Ultra is configured for Machine Envelope Control
(MEC) only. MEC will warn and prevent equipment motion in a
limit state. 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, see section 8.4 for monitored points on the machine. PMERail is NOT aware of any attachment fitted, therefore
make sure is in its least favourable position when setting any limit.
Height Limiting
Slew Limiting
Exit to previous
menu
8.1 PMERail Ultra Height Limitation
PMERail Ultra complies with RIS-1530-PLT Issue 4 height limiting requirements. Therefore a default height limit of 3.5m will activate automatically on start up if the bogies are
deployed or on their first deployment. Any height limit previously set will be replaced.

8.2.4 Machine Envelope Controller (MEC) - Virtual Wall PMERail Ultra
8.2.4.1 PMERail Ultra Virtual Wall Limitation Control
PMERail Ultra complies with NR MDL/004 ISSUE 2. slew limits requirements. Therefore
with a virtual wall slew limit active, as in addition to standard slew limit function (see section 8.2.4.2) the system will:

Activate an amber lamp to show a slew limit is active

The slewing speed of the machine will be reduced to one of three possible states:
 Linear speed at the tool point will be no greater than 2 m/s when MORE than 2m
(default) away from the set limit.
 Linear speed at the tool point will be no greater than 1 m/s when LESS than 2m
(default) away from the set limit.
 Linear speed at the tool point will be CONTROLLED by PMERail when LESS than
1m (default) away from the set limit. If the tool point reaches 1m (default) away
from the limit, PMERail will:
Motion cut slew at 1m (default) from the limit to allow PMERail to take over
slew control in the direction of slew travel only.
 To move closer to the slew limit, the
slew joystick must be returned to the
neutral position then back towards
the limit. The warning message show
here will be displayed, linear speed at
the tool point will be no greater than 1
m/s in this state.


At the limit, motion will be stopped.

It will be possible to move away from a limit at anytime, the linear speed at the tool
point speed will be increased back up to no greater than 2 m/s.

The counterweight will not induce the 1m/s state even if it comes within 2m of the
limit.
Care should be taken to test that the limit is set correctly. Observe the operational limitations given in section 4.
Once slew limits are set, the internal alarm will sound and the RED
LED will light if the equipment exceeds the either limit. Always
check that the slew limit activates at the set point. The limits cannot be deactivated if in the alarm state. Observe the operational limitations given in
section 4. Do not travel once a slew limit has been set.

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
PMERAIL has very few user serviceable parts. The safety controller / I/O module have
internal fuses that can be replaced if required. Section 10 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 PMERAIL systems operating environment, changes in usage can
occur. Prolec Ltd or the service agreement holder 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 PMERAIL, all appropriate technical bulletins relating to PMERAIL
must 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.

562600-000, Issue1.0, March 2014
18 Data Logger
PMERail has two data-logging functions. The data logging icon appearis in the bottom left of the screen. The data can only be viewed by extracting it from the system, contact your service agreement holder or Prolec Ltd for further assistance.
Where a data logging system is found not to be operational then the vehicle shall not be used until the fault is repaired and fully confirmed as operational. This requirement applies irrespective whether starting or partway through an operation.
1.
The Event Logger will make a record of any significant operational event (overload,
slew limit, etc), any error event (sensor failure etc), any manual intervention
(override, clock set etc) and any activity within the system set-up (calibration adjustment etc). The event logger will store the past two months worth of data after which
the oldest data will be deleted on a monthly basis.
2.
The Periodic Logger records the following data every 1 second:
Date
Lifting duty
Lift point radius
Slew angle
Gradient
Time
Load on hook
Lift point height
Cant
Operator code
The event logger will store the past two months worth of operational hours data, (NOT
elapsed time) after which the oldest data will be deleted on a monthly basis.

Appendix 2 Interlocks
1.
When the oscillating rail axle is locked the symbol shown here will appear
on the display. If the interlock was configured during installation the forward
and rear travel functions will be disabled when this symbol is visible.
2.
When the oscillating rail axle is locked, PMERail will
start to monitor the equivalent UNLOCKED duty. If either the lift capacity or the backward stability level of
the UNLOCKED duty is unsafe, the YELLOW
‘padlocks’ will be shown on the display. If the interlock
was configured during installation, the axle lock control
will be disabled preventing the axle from being
unlocked. Wheeled example shown.
The display will automatically revert back the top menu screen after ten seconds if a button has not been pressed.
