Funiculars & Cable Cars
Instead of using the traction current to trigger the SAS2-BR, reed switches (as
previously said) can be used, but for funiculars or cable cars it may be difficult to find
a solution to mounting magnets.
Instead, BOD2-RLY infra-red detectors can be used.
Run initially without the cable car fixed to the rope to confirm the correct motor
direction.
It may be necessary to increase the BOD2-RLY sensitivity, or to reduce the
Deceleration rate of the SAS2-BR to ensure the cable car stops at the intended
location.
On a funicular or a cable car with two cars, position the BOD2-RLY modules to
monitor the same car at the top and bottom of the run. Alternately, mount the BOD2-
RLY modules side by side at either the top or bottom of the run.
A centre station can be wired in the same way if required, although if precision is
required for stopping, then two BOD2-RLY modules may be required looking both up
and down the run.
