CAUTION: Before unpacking and installing the MCU W system, the user should carefully read the safety instructions below and ensure that they are followed at all times by all operators. Operators must be trained in the use and application of the MCU W system and accompanying products, in the context of the machine it is fitted to, before being allowed to operate that machine.

Please ensure that you understand all safety instructions. Familiarisation with the MCU W system components is recommended.

  • CMM should only be controlled from pre-determined zones or locations
  • The communication cable between the UCC controller and the MCU / MCU W cradle should be routed so to avoid a trip hazard
  • Do not put more than one MCU W into pairing mode at a time
  • For safety reasons it is recommended that the joystick docking station is mounted outside the CMM working area

Operation and maintenance

If the equipment is used in a manner not specified by the manufacturer, any protection provided by the equipment may be impaired.

  • Do not position the MCU W cradle in such a position that it would be difficult to operate the E-STOP
  • These products are only to be used with the appropriate Renishaw controller
  • Installation of the MCU must be performed by trained personnel
  • Do not edit any of the system files directly, only trained personnel may use the appropriate commissioning software package
  • Remove the power before performing any maintenance operations
  • Maintenance is restricted to procedures described in the maintenance section

STOP buttons

The MCU system offers three STOP buttons:

  • Emergency STOP switch - RED
  • Stop switch - grey (located on MCUlite-2 joystick)
  • STOP switch - YELLOW (located on MCU W joystick)
  • Keypad STOP button (MCU5 and MCU W)

MCU W battery

A lithium-ion battery is used to power the MCU W joystick. It has been placed in an enclosure to provide protection against short circuits, overcharging and physical shock.

  • Under no circumstances should attempts be made to open the battery enclosure - an unprotected battery is a hazard and can cause injury
  • The battery contains hazardous chemicals and should be disposed of in accordance with local legislation or returned to Renishaw for correct disposal
  • Only use the charger supplied
  • Do not store in direct sunlight or damp conditions
  • Do not heat or dispose of the battery in a fire
  • Do not short circuit and avoid forced discharge of the battery
  • If the battery becomes wet or physically damaged great care should be taken as it may become hot - if this occurs cease use immediately and dispose of the battery
  • If a battery starts to leak it should not be used and must be disposed of - care should be taken that any leaked fluids are not ingested or allowed to get into the eyes
  • Do not subject the battery to violent shock - internal damage to the battery could occur which could cause it to overheat
  • Do not attempt to charge the battery if the ambient temperature exceeds +40 °C (+104 °F)

Ensure that the international and national battery transport regulations are complied with when transporting batteries or MCU W. Lithium-ion batteries are classified as dangerous goods and strict controls apply on their shipment by air (UN3480). To reduce the risk of shipment delays, should you need to return the MCU W to Renishaw for any reason, ensure the batteries are fitted to the MCU W and are not sent separately. Ensure correct labelling on the outside of any consignment containing the MCU W batteries.
