18.2 Brake Rectifier
The Brake Rectifier is a device in the door gear motor junction box. The Brake Rectifier is supplied voltage
from the Controller and is activated by a Brake Relay on the PCB 154 Controller Board.
When the Controller supply voltage is 115 VAC and a 3017-5052 A-100 Brake Rectifier is installed inside the
door gear motor junction box, the output Brake voltage should be approximately 100 VDC loaded and
approximately 110 VDC unloaded.
When the Controller supply voltage is 230 VAC and a 3017-5050 A-200 Brake Rectifier is installed inside the
door gear motor junction box, the output Brake voltage should be approximately 100 VDC loaded and
approximately 177 VDC unloaded.
NOTE: Loaded = Connected to the gear motor brake;
Unloaded = Not connected to the gear motor brake.
When the Brake Rectifier is activated, it supplies voltage to the brake inside the gear motor and the brake is
released. The yellow and white wires supply voltage to the Brake Rectifier. This voltage is dependent on
what type of power supply was given to the Controller, either 115 VAC or 230 VAC. The two blue wires on
the brake rectifier are the activation connections. When these two wires touch each other, the brake rectifier is
activated and output voltage leaves the Brake Rectifier on the black and red wires.
Motor Brake Rectifier Wiring Diagram
The SC-325 Controllers are factory preset to 115 VAC and the
RS-500 Doors are factory prewired to require a 115 VAC power supply.
The SC-650 Controllers are factory preset to 230 VAC and the
RS-600 Doors are factory prewired to require a 230 VAC power supply.
