GB4 programming question
Posted: Tue Aug 27, 2013 8:30 pm
My GB4 is not responding to the 'F1' command given when in program mode. I am attempting to cancel any remnants of a previous program so I can enter a new program. (I prefer to enter the program each time so there are no remnant steps left in the controller to work around.) With the controller in program mode I have pressed F1 but it doesn't seem to clear. Steps I have entered previously still show up on the display.
I'm wondering if I have confused it as I turned it off at the wall plug when I could not get it to clear. On re-reading the manual it appears that it may treat such a cut-off of power as a power outtage and attempt to save its program to restart when next turned on. I had several failed firings because, unbeknown to me, a wire from the sending unit had become detached but was still sitting in place so the connection looked normal. It was possibly touching sometimes and not touching at others. ( I had an intruder, a ten-foot python, in my workshop and think it may have dislodged the wire). I tried a variety of settings which resulted in erratic firings, none of which worked until the disconnected wire was reconnected. Now I can't get it to clear using F1 and it seems to be running some phantom program of its own invention.
My understanding from the manual is that pressing F, then immediately pressing 1 ('1' being the unit number), when in program mode should clear any program in the memory for that kiln. Can anyone tell me if there's another step or procedure I'm missing, please?
I emailed Digitry but have not received a reply yet but need to get on with some firings and hope someone can shed some light.
(I normally turn the controller off when I'm not going to be using it. I have done so in the past with no complications; could this interfere in some way?)
I read a thread on Craftweb about GB4 problems but don't think the thread relates to mine, at least I'm optimistically hoping not.
Thanks, Jen
