CAR/HALL LANTERN LOGIC

Model HL757

The efficient way to add lantern logic and passing signal to existing control systems

Car/Hall Lantern Logic provides lantern drive logic to existing elevator control systems in which the lantern features were not provided as original equipment. The unique onboard logic of Model HL757A/B makes a wide range of applications possible. A direction preference circuit is created by the direction of travel or hall-stop priority.

Model HL757A/B differentiates between an up-stop and a down-stop even in cases where the system only provides a single stopping signal. A floor passing signal is also provided in the same fashion as Model DDPA/B. (See Model DDPA/B for details.)

Our technical support and application team is always available and our excellent service support is just a free phone call away.

Key features
● Provides lantern logic with a 2 stroke down pulse.
● Compatible with all major elevator control systems.
● Pilot relays provide isolation.
● Differentiates between an up-stop and a down-stop at floor signals.
● Average installation time (determined by direct field feedback) is 4 hours motor room wiring.

Interface

Model HL757A/B enhances the existing controller by providing advanced lantern drive logic and the addition of a floor passing signal. Interface with the system control unit is achieved by establishing up to 18 parallel connections. Floor selection can also be provided to hall lantern systems. Input to the floor selection system is derived from the HL757. A floor passing signal is also provided in the same fashion as Model DDPA/B. (See Model DDPA/B for details.)

Although compatible with all major control systems, the system control logic section voltage is determined by the user-selected lantern system. When matched with your system’s control voltage, Model HL757A/B provides the correct interface relay type. This device is available with mounting hardware and a template, or provided within a separate enclosure.

Model HL757 is only one of Electrodyn's many innovative products to help you modernize your elevator system. Choose Electrodyn: we work with you when you have work to do!
