Description

If the gun has been on for the amount of time specified as Canister Check Time and the amount of change in cylinder position counts has not reached the Minimum Canister Change Counts, this alarm will post. This can be caused by low flow rates, where it takes longer to see this minimum cylinder position change. Could be an indicator of trouble with the linear potentiometer or the feedback circuit.: Lower the Minimum Canister Change Counts or increase the Canister Check Time. Check the feedback from the linear potentiometer or repair the low voltage wire for the canister feedback circuit.
