Faults

Fault 1: Hydraulic Fluid >65C
The hydraulic fluid is too hot.
Refer to Temperature on page 162.
Fault 1: Intensifier 1 Overstroke to Left
Fault 1: Intensifier 1 Overstroke to Right
The intensifier is overstroking.
Refer to The intensifier overstrokes in 1 direction on page 158.
Fault 1: Low Inlet Water Pressure
The water pressure at the manifold is lower than the minimum setting.
The supply pressure is lower than 2.8 bar (280 kPa / 40 psi).
Increase the supply pressure.
Pressure is lost because of a leak.
Identify the source of a leak and correct the problem.
The supply water is turned off.
Turn the supply water.
ON
Fault 2: Hydraulic Fluid >65C for >3 Minutes
The hydraulic fluid is too hot.
