Wiring Bodyguard-T
Note
: The Bodyguard-T does not require a lockout relay for use with the MC521 PRO control box. The MC521
PRO control box generates the data signals for door open, closing, and closed positions. Refer to Attachment 5 as
applicable for wiring connections. Program the Bodyguard-T Relay Output to #1.
Wiring Superscan-T
Refer to Attachment 5 as applicable for wiring connections. To inhibit the Stall Superscan-T, a switch is
required in series with the Stall output.
Wiring Holding Beam
The Holding Beam input is used in applications when there is a rail-mounted holding beam. When the door is
closing and the beam is obstructed, the door will not open until the door is completely closed and the header-
mounted sensor becomes active. When the door is open and the beam is obstructed, the door will remain open.
Refer to Attachment 5 as applicable for wiring connections.
