MP SERIES CONE CRUSHER TECHNICAL REFERENCE MANUAL
0.4.3.2 Electrical Fault Situations
Electrical faults may be caused by component
failures such as loose or damaged wiring.
Diagnostics are provided through pilot lights,
alarms, and help messages.
0.4.3.3 Program Changes
An electric outlet may be supplied in the logic
center and control cabinet for programming
purposes only. Do not connect any electrical tools
to this outlet. The tool may cause electrical
disturbances in the machine control system. This
could alter the machine control program and cause
unpredictable machine operation.
0.4.4 Hydraulic Safety During Maintenance
and Repair
Before proceeding with any repair, maintenance or
diagnostic procedures on the hydraulic system,
bring all components to a zero energy state,
including cylinders, accumulators, spring loaded
hydraulic devices, circuitry between valves and
actuators, etc.
– Mineral and other oils and additives can
cause skin irritation. Inhaled oil mist can
also cause internal irritation, headache or
nausea. Avoid repeated exposure to these
materials. Use appropriate personal
protective equipment.
NOTICE
Electrical connections can and do loosen
due to vibration in transit and thermal
expansion of the wires and lugs in
operation. This is especially true after initial
delivery, break in and after major relocation.
Loose connections increase current draw,
which can result in false trips, intermittent
circuits, and burned-out components. As
part of the start-up, check and retighten as
necessary all electrical connections in the
electrical enclosure. Repeat after the first
forty to fifty hours of operation. This work
must be performed by properly trained
personnel.
NOTICE
Improper phasing will damage backstops in
conveyor drive reducers and may damage
hydraulic system components.
WARNING
Changes to Metso Minerals’ supplied control
program should be made only by Metso
Minerals personnel. Faulty program code
may cause the machine to behave
unexpectedly. Any changes to interlock
circuitry must be made with extreme caution
and be reviewed and approved in writing by
Metso Minerals before implementation.
NOTICE
Do not use the logic center or control
cabinet’s outlet for anything other than a
programming device!
DANGER
Follow all established lockout procedures.
For maintenance work, disconnect all
devices from electric, pneumatic and
hydraulic power sources and follow lockout
procedures.
The lockout instructions, locks, tags and the
blocking/restraining devices provided are
designed for your protection. Your
responsibility is to follow the program and
use the proper equipment.
Remember:
• Follow procedures.
• Stay alert.
• Do not take anything for granted.
• Verify lockout.
• Tag must identify the work being done
and the person(s) who locked and
tagged the control.
• Locks and tags are changed with each
shift that comes on.
Work to eliminate injury and death.
Follow proper procedures at all times!
