Problem 26

Alarm keeps sounding

Alarm Type Information

There are various alarms built into the Sprayer software to indicate when things are not right. The following text covers all of the alarms, their settings and what they mean. Any alarm for a facility not in- stalled should normally be set to Never Alarm. Common uninstalled functions include Pump speed and

Pressure.

Rate

The Rate alarm indicates that the Sprayer is not controlling to the programmed rate in Auto. This shows up on the operating screen with the value in the Rate window alternating from the target rate (Yellow background) to the actual rate, (White background)

If the actual rate is zero, this could be a faulty flow- meter, out of spray, pump failure, or faulty harness. If the rate is low, it usually indicates pump problems or other plumbing issues with flow, including pump too small for the rate being attempted at the speed the Sprayer is running at. If achieved rate is higher, this could be due to the regulator being jammed, faulty, or fully at one end of travel with blockages in the return line from the regulator.
