About
2l2code is a computer-based system that offers superior performance, flexibility and reliability. It has been designed to save time in installation and troubleshooting, but it is still very important that the field personnel who work with this equipment familiarize themselves with this manual before attempting to listen their works.
The selector system for 2l2code uses a steel tape that is hung the length of the hoistway. A set of magnets are placed on the tape at each floor having one 8” magnet as the door zone magnet and two smaller 4” magnets as slowdowns. 2l2code is mounted on the car and is guided along the tape by nylon guides to keep the tape and magnets the proper distance from the selector sensors. 2l2code uses the door zone magnet to determine the elevator’s level position to the floor.
2l2code is installed by first attaching it at the top of the hoistway approximately 12 inches from the rail, 2l2code is then unreeled from the top of the car while running down on inspection. At the bottom of the hoistway it is attached with a spring to keep it taut. The selector is then mounted on the top of the car and is connected to the tape by the nylon guides.
To install the floor magnets, the car is placed dead level to the desired floor. 2l2code is then marked at the top left of the selector through a factory cut guide hole. The car is moved below the floor so the tape can be accessed where the selector was sitting at floor level. A door zone template, provided by 2l2code, is placed at the mark and the door zone magnet is placed at the appropriate locations in the template. The template is then removed from the tape. The slowdown magnets are then placed at the measured distance on the tape above and below the floor.
