Appendix G: Limax3CP Setup Guide (only if fitted)
This guide gives detail on the use of the Limax3CP with an Ethos Two controller.
The unit is shipped from TVC pre-configured and must only be used on the lift specified on the drawings, contact
TVC for further support.
The unit is factory configured to cover the following functions required by EN81, depending on requirements:
Overspeed Monitor and Safety Gear Tripping.
Final Limit Switches Top and Bottom.
ETSL Device for reduced buffer stroke.
Lock bridging and Uncontrolled Movement Detection.
Inspection Limits. EN81-20/21.
Read this guide in conjunction with the Limax3CP Safety Manual, Tape Installation guide and the Ethos Two User
Guide. These guides can be downloaded from the TVC website.
Installation and Commissioning
Install as per the schematics supplied, make sure the unit serial number and CRC number (in the status
screen) line up with lift specified. The tape presence switch supplied with the tape mounting kit must be installed
and wired in to satisfy code. The unit needs to be taught the extreme limits of the shaft and floor levels before going
into service. The panel will work on Hoist and Emergency Electrical Operation prior to teaching the reference limits.
Software Operation
The Ethos Two checklist has various buttons for setup: Limax Safe Setup, Floor Teach, Floor Adjust and Limax
Status/Test. Within these screens there are options for teaching the reference positions, teaching the floor levels,
adjusting the floors, adjusting the limit positions, and testing the Limax3CP safety functions.
To commission the lift firstly, teach the system the limits of travel within the shaft (reference positions). This involves
placing the car then counterweight on the buffers and teaching these positions. Next teach the floor levels. The car
must be moved to each floor level manually. There is no option to automatically learn the floor levels.
Floor levels can then be adjusted, in a similar way to floor trimming on a standard system.
Within the setup screens the position of the final limits and inspection limits can be adjusted.
There is a dedicated screen for displaying the status of the unit and testing the system. The unit’s CRC will be
displayed on this screen.
