HYDROFIT™ Owner’s Information Manual
WARNING: The use and ownership of this work is defined in the legend upon the front page hereof.
Separate Basement Zone
This feature is used where substantial traffic is expected from the basement area
(such as would occur in a large basement garage) and there are sufficient elevators
in the group to create a single floor lobby zone and a separate basement zone.
Park and Shutdown Operation
Park and Shutdown Operation, activated by either a keyswitch or EMS, parks the car
at the lobby. When activated, the car is removed from group operations. If the car
has pending car calls, it answers any remaining car calls. Once the car has no
further demand, the car travels to the lobby and parks with the doors closed (parking
with doors open is available). The car remains out of service until the keyswitch is
placed in the OFF position. If a lobby panel is provided, a jewel illuminates when
operation is complete.
Delayed Car Protection
Any car not responding to a demand for service within a predetermined time interval
is removed from group operation. This allows other cars in the group to pick up calls
previously assigned to the delayed car.
Uneven Stops / Travel
Odd travel occurs when one or more cars in a group serve additional or different
landings in a building. Mid-building travel occurs when certain cars within the group
do not serve landings located in the middle of the building (also referred to as an
express zone). When a car is traveling through such a zone, the position indicator
displays “EZ”.
Double Riser of Hall Button Operation
Double-Riser Operation allows two hall buttons at a landing to work in parallel and to
illuminate simultaneously. When either of the hall buttons at the landing is pressed,
the call is registered.
Separate Hall Button Riser
This operation uses two sets of hall buttons, one for normal group operation and the
other for providing expeditious service to certain landings during specified periods of
the day. Separate riser operation is initiated by a keyswitch. When activated, those
cars connected to the separate riser answer hall calls registered on it and ignore the
hall calls on the primary riser. Cars operating on the separate riser are not subject
to group dispatching features such as Moderate Incoming Traffic.
Split Group Operation
In a building with two major tenants, it is often desirable to divide a group of
elevators into two subgroups during certain periods of the day. Each subgroup
serves one of the tenants.
