Hoistway Safety String
1. Install hoistway safety string devices as shown in your job prints.
2. Install final limit switches at each terminal.
3. Test each device individually after the string is complete to see that it does in fact open
the safety string as it should.
In Motion 4000 installations, Final Limit switches are part of the hoistway safety string and
should not open unless the car overruns the terminal landing.
Cartop Safety String
1. Install the cartop inspection station and stop switch as shown in your job prints.
2. Install cartop safety string devices as shown in the job prints.
3. If the in-car stop switch is in place, wire it into the string as shown.
4. Verify that the cartop inspection controls work correctly.
Hoistway Switches
Virtual/Physical/Unused
With the exception of the final limit switches, which are always physical, other slowdown
switches used in Motion 4000 installations may be physical, virtual, or unused:
• Physical: Normal switches installed in hoistway.
• Virtual: Switches placed in “software” by the positioning system. Please refer to “Terminal
Switch Options, 69 - 74” on page 4-127.
• Unused: Depending upon car contract speed, some hoistway switch positions may be
unused.
LS-EDGE Hoistway switch requirements for LS-EDGE are like those for ELGO except that
ETS, when required, are 5” magnet strips. Please refer to “LS-EDGE Steel Tape” on page 3-5.
