Remedy · Remède

Check, clean, and possibly replace the air cap. Check for oscillating air pressure on the output of the I/P transducer. If found, replace the transducer. Check for a large loss of air supply pressure or pinched air lines. If the alarm occurs on both Fan Air and Atomizing Air or many robots, then possibly increase the Max. error from setpoint parameter.
