Message
Description/Cause
Corrective Actions
E0435
INJ. INT. CIRCUIT
Injector assembly internal circuit issue.
Contact factory.
E0436
INJ. FOAM METER
Injector assembly foam flow meter issue.
Check if foam flow meter cable is plugged in.
Check if red light on flow meter connector is ON.
Contact factory for replacement
W0437
INJ. CAPACITY LIMIT

System foam manifold pressure high!
Check foam flow calibration of system
components.
Check foam lines for obstructions.
W0464
SYS. BACKUP CNTL ACT.
System switched to backup
hydraulic controller.
Main hydraulic controller board may be defective.
Contact factory.
E0465
SYS. FOAM CALIBRATION
