AMF (and others) Automatic Bumpers
The Majority of Automatic Bumpers can be activated up or down by the closure of a switch. The Duo Units
include a relay for this purpose. The contacts for this replay can be found on pins 4 and 12 of the Machine
Connection plugs for both the Odd and Even lanes. Run the Automatic Bumper Connection cable (SBC) from the
Duo Hardware Unit to the Automatic Bumper Controller for your bumpers.
Note: The relay on the Duo Unit will only handle the switching of low voltage (or
preferably no voltage) only. DO NOT attempt to place any high voltage
across the relay contacts or you WILL DAMAGE the Duo unit. If you are
unsure how to connect your Automatic Bumpers, contact the
manufacturer of the bumper units.
