I have a 330a two stop that has been off for about a month. It Was running fine previously. Went into the machine room to do an annual test and foud no screen reed out ; found the 24v logic voltage supply was no good and changed. Now I have a reed out of "BLOCK READY 0=01 1ii unv". Attemted to reset many times to no avail. Can not even run on inspection. Does any one know what could be wrong? Much appreciated.

battery may be dead, did you check the parameter?

Stupid question, did u try to jump out the pressure switch?

Well,don't think there is a battery backup, RAM board will hold parameters, agree try' jumping pressure sw. Sad to say its a Schindler, you never know. Unv means unavailable. Did you do a reboot? Press button on the board that is mounted to the Main relay board 3times in 1sec. Intervals,then when screen shows system boot, press and hold for 5 sec. This will reboot entire system. Sometimes you have to put controller on MR inspection. This clears most errors.

Is there any display on the Nordic starter?

no no. hit the reset button on the gcio360 board one time .when the red light on the board blinks twice hit it again. if it was the pressure switch it would read PSW.

So I assume the multi-tap fixed it?
