BASIC APPLICATION GUIDELINES & PROGRAMMING
_________________________________________________________________________________________________________
Int.1 Sets PSO 1 RX1 Enable
Int.1 Set by PSO 4 RX1 Occupancy
Int.2 Sets PSO 1 RX1 Enable
Int.2 Set by PSO 5 RX1 Occupancy
Note that assigning an internal channel multiple times effectively ANDs the terms setting it, so in
the case above either PSO 4 or 5 RX1 Occupancy de-energizing will de-energize PSO 1 RX 1
Enable.
5.2.5 Stick Cancel Input
The Stick Cancel input should "normally" be energized. De-energizing the
input will cancel and set sticks and not allow another stick to be set.
The GCP5000(GCE) allows an external input to be used to cancel a stick. To use this
Set the Stick Cancel Input Used to Yes on the PSO 'n 'Transmitter menu
Assign the Stick Cancel input to an input (or it can be set by internal logic) for example,
IN 7.1 PSO 1 Stick Cancel.
De-energizing the input causes the stick to be canceled.
If a PSO Enable input is used and wired to an external PSO 4000, the
Health output from this PSO can be wired to a Stick Cancel output on the
GCE, this will prevent a failure of the external PSO resulting in the Stick
for the exit track remaining set.
