Inputs
English
FD4 can handle different signals from a controller, these can be
sourced from +24 VDC or 0 VDC.
Binary signals
Binary code is a standardized way to control outputs that are used
for floor displays.
Default binary inputs (for 15 floors)
Input 1
Binary signal 1 Input 5
Input 2
Binary signal 2 Input 6
Input 3
Binary signal 4 Input 7
Input 4
Binary signal 8 Input 8
Gray code signals
Gray code is an uncommon way to control floor displays. You only
change one input at a time, which minimizes the risk of error. It is
often used on older controllers.
Default gray code inputs (for 15 floors)
Input 1
Gray code 1
Input 2
Gray code 2
Input 3
Gray code 3
Input 4
Gray code 4
Decimal signals (one-floor-per-pin)
The old way to control floor displays are called Decimal or
one-floor-per-pin.
Default decimal inputs
Input 1
Floor 1
Input 2
Floor 2
Input 3
Floor 3
Input 4
Floor 4
Pulse signals
Pulse signals are for use with an encoder. By connecting an
encoder to FD4 you can show floors, and play floor messages on
each floor, regardless to the type of installation and controller.
Default pulse inputs
Input 1
Pulse A
Input 2
Pulse A
Input 3
Pulse B
Input 4
