Tunnel Master® wbc Installation Guide

The input board provides monitoring and error reporting of all 48 inputs wired to the inputs terminal
block. Auxiliary inputs help report the state of the tunnel. If an error condition or event occurs, you can
use the inputs as monitors to receive alerts or set the tunnel into a panic stop mode. The input board
works independently of the main CPU board.
The input board includes eight stop inputs. One stop input is controlled by the computer.
Seven stop inputs are directly controlled by push-button stops. All stop input circuits must be
closed for the conveyor to work.
The input board includes eight start inputs. One start input is controlled by computer. Seven
start inputs are directly controlled by push-button starts.
The input board includes 48 undesignated, optically isolated inputs. The board also features on-board
relays to control the horn and the conveyor. A DIP switch bank controls the delay time between the
horn and the conveyor start.
