I/O port does not work..

[Darkreefer]

I am trying to hook up my ACIII I/O port to float switches. I wired them up correctly (8 minidin straight through cable) Tested continuity for pins switch #1 and #2 and #8 ground wire.

I also tested to the pins, continuity with the float switches opened and closed and everything is fine. But for some reason the ACIII does not see the float switches.

What could be wrong ?

Thanks

Can we see the code you are using...

If Switch1 CLOSED Then TOP ON
If Switch2 OPEN Then TOP OFF
If Switch1 CLOSED Then SW1 ON
If Switch1 OPEN Then SW1 OFF
If Switch2 CLOSED Then SW2 ON
If Switch2 OPEN Then SW2 OFF

What firmware version are you using?

[Darkreefer]

It says 3.00s 3A06. Never flashed.

My whole code is:

nomenclature:
act is actinic T-5
MH is halide
MON is moonlight
co2 is regulator
skm is skimmer
RTP is return pump
HTR is heater
CHL is chiller
CHP is chiller pump
FAN is Icecap fans
RFL is refugium lights
TOP is auto top off pump
FPR is ca Reactor feed pump
ALM is alarm
SW1 is low level float sw
SW2 is high level float sw

Thanks Curt for the help today. I will re-wire the floats later.

Kasei - What was the problem?

[scolley]

I'm having this EXACT same problem, except with a brand new AC Jr.

Pins 1 & 8 have continuity, and around 4.4v running across them. But if I set up code to shut something off if SWITCH1 is ON, it does not work. Would love to know how this got resolved for Darkreefer.

[scolley]

I figured it out. It appears on the Jr. the required pins are 1 & 2. The documentation is not consistent with that of the other AC's, where you pair up an Input and a Ground, for the Jr. they are labeled as External Switch Input and External Switch Output.

With pins 1 & 2 wired, it's working like a charm now.
