• PRESS – Fan system pressure. Increased cooling
demand and increased engine speed will increase this
pressure.
• PUMP – Displays the current pump command. This will
range from 5 to 100% and change in response to cooling
demand and engine speed.
• STATUS – Displays the error status of the fan system:
0 = okay.
Bit 1 = fan pressure transducer out of range.
Bit 2 = fan control valve digital output fault.
Bit 3 = fault is set if fan pressure is below 500 psi (34,5
bar) after the system is initialized. Will cause the backup
coil to energize and try to fully stroke the pump.
