Graco® now includes the adjustable pressure imbalance feature on electric Reactors (models E-20, E-30, E-XP1, E-XP2), a feature that was previously only available on hydraulic Reactors (models H-25, H-40, H-50, H-XP2, H-XP3). The pressure imbalance function (status code E24) detects conditions that can cause off-ratio spray, such as loss of feed pressure/supply, pump seal failure, clogged fluid inlet filter, or a fluid leak.
The pressure imbalance default is factory-set at 500 psi (35 bar, 3.5 MPa). This change allows the pressure to be adjusted and set at 100 to 999 psi in 100 psi increments. Values less than 500 would be selected for tighter ratio error detection, while higher values would be selected for looser detection or to avoid nuisance alarms.
