What prevents possible vehicle-to-vehicle collisions?

Block Zone Logic with redundant sensing methods.

Perfectly

Track side control of RVs is accomplished via..

a separate conductor on the bus bar. This conductor is divided up into zones throughout the ride track.

Perfectly

In Block Zone Logic, a particular zone will selectively have 24VDC power..

switched on and off depending on the status of the zone ahead of it.

Generally, if the zone ahead is clear of a ride vehicle..

the current zone will be cleared to move the vehicle in it forward.

Switching of the individual zones is handled directly and discretely by..

The RSS through ride power switching enclosures (RSD02s) located around the track.

What is a shotgun gate?

A gate designed to control the crowd entering the ride by dividing them into separate columns to match the rows of the ride vehicle.

How many ADA gates are there?

One is 28” wide, the other is 49” wide.

The shotgun gates are actuated by..

a pair of pneumatic cylinders that are situated in the frame beneath the floor level of the load platform.

Zones L1A, L1B, L2A and L2B represent..

the zones in which the vehicles park by the load gates.

How fast does the ride move forward at full speed?

4.0 ft. / sec

If the 24VDC enable signal is modulating at 15 Hz..

It is interpreted in two ways. If the vehicle was just dispatched, and the track is in maintenance mode, AND inspection mode has been selected from OCC15 - The vehicle will look for the proper magnet pattern to park over the inspection pit.

What does SSC stand for?

Sub System Controller

What does VDC stand for?

Voltage Direct Current

What does VFD stand for?

Variable Frequency Drive

What is an RSD?

Ride Show Supervisor Distribution Box

What does PQS stand for?

Personal Qualification Standards

RSS01 & RSS02..

Main Show Processors

RSS03..

Serial Connector

SSC04

Break Room Aliens, Twins, Dispatcher

SSC06

TAFKAB, Smoke Blast, Taxi, Water Laser, Etc.

SSC08

Big Bug / Show Curtains

SSC09

Tailor and Coach Aliens

SSC11

Track Switch Controls

OCC stands for..

Operator Control Console

The main control system responsible for the over all sequencing of the ride and show systems in the attraction..

The RSS (Ride Show Supervisor)

RSS02 has two processors..

One for the inside track, one for the outside.

How many AC drives are on board an RV?

2. The rotational and linear drives (Allen Bradley 1336 and 1305 respectively).

The RV converts 3 phase 480VAC to DC power through..

A rectifier.

Onboard electronics are..

DC powered.

2 phases keep the onboard electronics running when..

One phase is interrupted. This prevents the lengthy restart time incurred when the drive is completely powered down.

Current Transducers..

Help control the movement of vehicles from one zone to the next.

Current transducers have a built in relay to monitor..

One of the power feeds to the bus bar (B Phase).

When a vehicle enters a clear zone, the CT will..

Sense the current draw on B Phase and send a 24VDC signal through the relay to the Flex I/) module in the RSD cabinet.

An RSD sends information to the RSS via an..

Allen Bradely Remote I/O adapter (RIO 1794-ASB).

The CTs are located..

In the RSD02 enclosures around the track.

RSD02 cabinets contain..

Current Transducers.

CT are redundant..

to prevent issue in case of failure.

If the RSS detects that the CTs in one zone do not agree for more than 1 second..

It will generate a ride stop.

To prevent unintended vehicle motion from occurring, each ride vehicle has..

an electrical contactor located between the linear drive and the propulsion motor; this is the power contactor.

What does SCC stand for?

Show Control Console

What does RCC stand for?

Ride Control Console

The programmable controllers throughout the attraction communicate witch each other over..

the Ethernet network. RRS03 is a data concentrator that is used to minimize the number of logical connections and organize the data being passed between the programmable controllers.
