The stick cancel timer is used to cancel the stick if it remains set for more than the configured
time.
The user can select an external input (or internal logic) to cancel the stick. When Stick Cancel
Input Used is set to
Yes
, the PSO ‘n’ Stick RX’m’ Cancel Input (e.g., PSO 1 Stick RX1 Cancel
Input) is available to be used in the
System Inputs.
If an external PSO module (e.g., a PSO4000) is used at the crossing to provide additional PSO
receivers to extend the approaches and these are fed into a PSO receiver enable input, then a
failure of these receivers can result in the stick not being cleared. This can be mitigated by
wiring the PSO health output from the external PSO module into the stick cancel input of the
PSO in the GCE system.
WARNING
A FAILURE OF THE EXIT TRACK WHEN THE STICK IS SET CAN
RESULT IN A FAILURE TO ACTIVATE THE CROSSING.
THE STICK CANCEL TIMER VALUE SHOULD BE CHOSEN TO
CANCEL THE STICK BEFORE ANOTHER TRAIN CAN APPROACH.
THE STICK CANCEL INPUT SHOULD BE USED WHERE
APPROPRIATE TO CANCEL THE STICK.
The Wrap Pickup Delay Time is used to provide pickup delay when using track wrap on the
PSO receivers. A common value is used for both receivers on the PSO.
Figure 10-10 PSO Transmitter when in Mode = Crossing
When the PSO Module Mode is set to Rx/Tx, then the PSO transmitter is used and the 2
receivers can optionally be used as shown in Figure 10-13. In this mode, this PSO is logically
independent of other PSO crossing logic used in the GCE system. Occupancy of these
receivers will not automatically activate the crossing. If they are required to be part of the
