7.3 Motors and heating elements
Starting equipment for the drive motor, auxiliary motors and heating
elements are normally not supplied by Sandvik. Fuses, relays, motor
protectors and control units must be installed in the appropriate switchgear
cabinets.
7.3.1 M1 – Crusher motor
The power supply to the motor must incorporate the necessary fuses, relay
and motor protector, all installed in an appropriate switchgear cabinet.
The main drive motor of the crusher can be started in several different ways,
depending on the power supply available:
• Direct on-line starter
• Electronic soft starter
Starting and stopping can be made possible either by buttons or via software.
7.3.2 M2 – Lubrication pump
The power supply to the motor must incorporate the necessary fuse, relay
and motor protector, all installed in an electrical cabinet. Starting and
stopping can be made possible either by buttons or via software.
NOTE! The M1 relay must be interlocked with the power supply to the crusher’s
drive motor, so it is only possible to run the crusher when the lubrication
pump M2 is in operation.
