Errors
Solution
Perform pressure
relief procedure;
Cycle Power; Verify
Dispense valve func-
tion; Perform weight
check verification;
Reduce flow rate.
Lower flow rate;
reduce outlet pres-
sure drop; Verify
material temperature.
Lower flow rate;
reduce outlet pres-
sure drop; Verify
material temperature.
Cycle Power Lower
flow rate; reduce out-
let pressure drop;
Verify material tem-
perature.
Set Pre-Charge to
zero. Monitor outlet
pressure; Adjust
Pre-Charge pressure.
Contact Graco cus-
tomer service.
From the Mainte-
nance screen select
Dispense valve Auto.
Complete calibration
procedure.
Cycle Power verify
motor torque during
dispense.
Perform calibration
procedure.
