Using 2 Dosing Units with 4 pumps each.
The S cable of the 2nd is connected to the free S Port of the first.
One Dosing Unit is working great the other till yesterday.
From yesterday:
Green Led: ON
Yellow Led: ON
&
The first pump continiusly working- it stuck (red Led always ON).
If I press any of the other 3 buttons no pump reacts, no Red Led goes On.
Is I go to PLC/ socket functions/activate manual override and activate any of the other 3 pumps, no Led goes On, no pump goes On.
If I try to deactivate the first pump in PLC, I see it OFF but it is stuck ON (Led On).
Unplug & Plug again to S port (of the 1st Dosing unit,yellow Led went Off and On) unplug from the power & the S port and plug again, reprogram the numbering, nothing change.
The fisrt pump stucks On the others do not work.
Please advive what to do, it is critical for my system.
PS. You know Merphy rules, in the first pump that got stuck my nitrite filter was connected and my tank went up to nitate..
