Module Connectors Per Board
Top Board, TC-FCL
This section provides information about user-accessible module connections.
J4, J5 J4 is a modular, CAN connector for serial module control. (See preceding informa-
tion about termination enabling jumper JP1.) J5 provides auxiliary connections that can be
used to directly lift the machine brake, regardless of controller status.
The level of the pick voltage is adjusted using potentiometer R67. The maximum pick voltage
range is determined by input voltage to the module and whether the input connection is single
phase, FCL1/FCL2, or three phase, FCL1/FCL2/FCL3.
J3 J3 provides control signals to the TC-FCP board and accepts feedback voltages from the
TC-FCP board.
J6 On mBrake Rev 2 or lower, J6 accepts DC power voltages from the logic power supply
board (TC-LPS).
J6 On mBrake Rev 3 or higher, J6 accepts 24v external power only when the CAN bus is
not used.
Middle Board, TC-LPS (used only on mBrake Rev 2 or lower)
1 and 2 bus power connections from the controller are connected to TC-LPS connector
J1. As viewed from the front of the connector, pinout is:
This board provides DC power to the logic board through connector J2.
