MR 175 Handheld Pendant, Manual
Maintenance and Service
The MR175 is typically “hardwired” into the customers pendant control unit.
Maintenance is typically restricted to cleaning the unit. If for any unforeseen reason the MR175
stop transmitting or stop responding then it may be reset by pushing a recessed small button
located between the JOG and TOOL-In/Out button. This button can be depressed using a small
screwdriver or a paperclip pin.
Cleaning:
The unit maybe cleaned with typical household detergents. Use a damp cloth to wipe off any
dirt grease etc. Do not use ACETON based cleaning products.
The magnets may regularly attract ferromagnetic metal shavings. To clean use a pad with
isopropyl alcohol and wipe off the button area of the magnets until the metal shavings are
removed and the magnet surface is clean again.
Magnets:
The magnets are covered with a silicon pad for protection of the magnet. Do not remove the
pad as it will expose the magnet. Magnets are made of rear-earth metals and are brittle.
Magnets without a protection will easily shatter.
Cable Replacement:
In the harsh environment of machine shops it is possibly that the cable becomes damaged or
severed. In this case the cable maybe replaced by opening up the unit and the entire cable be
replaced with a new replacement cable.
Remove the bottom cover of the MR175
Loosen the screw on the manual pulse generator where shielding wires are attached.
Unplug the 10pin Molex connection from the PC board.
Carefully slide out the cable boot and discard the damaged cable
Install new cable following the steps above in reverse order.
Other Repairs:
Any other necessary repair shall be the factory.
