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 4-126.
• 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.
Seismic Equipment
A “ring and string” circuit detects excessive counterweight motion caused by a seismic distur-
bance. When motion is detected, the car will make a full stop. After stopping, the car will move
to and level at the next available floor in the direction away from the counterweight. After level-
ing, the car will open its doors and allow passengers to exit.
Modes of operation other than Automatic, for example Fire Phase II or Attendant mode, allow
different operating options when potential counterweight derailment has been detected.
Your job may also use a lateral and/or vertical acceleration sensor to detect seismic activity. At
this point, you should install counterweight movement detection and seismic sensors in accor-
dance with your job prints and seismic monitor manufacturer instructions.
