10.2.3 Sensor Activation (10K / BlueBUS)
Activation of an open-direction or close-direction 10K or BlueBUS sensor input will stop an opening gate within
two seconds and reverse it toward the opposite direction until the limit is reached.
Sensor inputs will only be functional if a sensor is detected at power-up or during a manual learn of sensors.
Appropriate sensors detected at these inputs will be treated as Type B2 external entrapment devices per
UL325.
When learned, the sensor connected to the 10K input must have a 10K terminated sensor connected for
monitoring purposes. These inputs are normally open, and when closed, will be active and the associated
LED(s) will turn on.
Open-direction sensor activation behavior includes:
’ The associated LED will ash three times if activated and preventing gate operation.
’ The reversal toward the close limit will be limited to 0.5s if any loop or open inputs are active, and the full
reversal will be completed when all the inputs are clear.
’ If the close-direction sensor input is activated during the reverse to close, then the gate will stop and
perform a 0.5s reversal toward open.
’ The close timer will be disabled until a renewed run command (open, close, loop, etc.) is received.
’ If the Type A inherent current sensor is tripped while the gate is reversing toward close, then the operator
will perform a 0.5s reversal and stop in “hard shutdown”.
’ A re open input will still attempt to open the gate even if the open-direction sensor input is activated.
’ Activation of the open-direction sensor input (shorted to common or closed) will prevent the gate from
opening normally unless the controller did not learn the input with a sensor.
Closen-direction sensor activation behavior includes:
’ The associated LED will ash three times if activated and preventing gate operation.
’ If an open-direction sensor input is activated during the reverse to open, then the gate will stop and
perform a 0.5s reversal toward close.
’ The close timer will be disabled until a renewed run command is received.
’ If the Type A inherent current sensor is tripped while the gate is reversing toward open, then the operator
will perform a 0.5s reversal and stop in “hard shutdown”.
’ Activation of the close-direction sensor input (shorted to common or open) will prevent the gate from
closing normally unless the controller did not learn the input with a sensor.
The following section describes the behavior of the gate when the 10K and BlueBUS open and closed sensors
are activated.
