I'm trying to setup a canopy latch alarm on my G3X GDU-370 (Non-touch). I've got the micro-switch setup behind the pin behind the panel. It's been wired with the normally open lead to ground Discrete In 1 on Pin 40 - J244 on GEA 24.
I've tried configuring the channel as a "Canopy Open" alarm with Active Low / High and I can't get it to trigger.
Per the manual...
When configured as Active Low, the inputs conform to the following specification:
Active: Vin < 3.5 VDC, or Rin < 375 Ω
Inactive: Vin > 8 VDC, or Rin > 100 kΩ
When configured as Active High the inputs conform to the following specification:
Active: Vin > 8 VDC, or Rin > 100 kΩ
Inactive: Vin < 3.5 VDC, or Rin < 375 Ω
So... There's no internall pull-up resistor and I need to setup a pull up? Behind this, I can't find any example circuits. Has anyone tried to setup a discrete channel on the G3X?
Thanks!
