Apex Dos DDR.....Switch open or closed?

[clhardy5]

I've been running my Apex dos with DDR for several months now - without a hiccup. Usually on the dashboard the DDRALK and DDRCalc switches are both closed - I've never seen them open. However today, the DDRALK switch says 'open' and DDRCALC is still closed. What do these 'switches' control....and what should they be on? Open or closed?

Moved to the controller forum! Maybe this will help get you an answer!

The DDR's optical sensors report CLOSED when they are covered with liquid, and OPEN when the liquid level is below the sensor. This is the same for Neptune's optical sensors used to measure water levels in a sump or barrel.

You can use the status of these switches in your Apex programming to send you an alert when the DDR is low, or even to turn off the DOS until you have a chance to refill the DDR.

Example to send an alarm:
[EmailAlm]
Set OFF
If DDRALK OPEN Then ON

Example to stop the DOS:
(add this to the Advanced tab on your DOS)
If DDRALK OPEN Then OFF
