Norac UC4 - Hydraulic Oil Overheats

17
4.3.7
 Hydraulic oil overheat
 Sprayer shuts down or alarm sounds due to the hydraulic oil overheat
Possible Cause(s) Suggested Solution(s)
a) High performance
automatic boom
leveling system
requiring elevated
amounts of hydraulic
power to constantly
maintain proper
setpoint is increasing
oil temperature
a) Lowering the Sensitivity ("Sensi")
setting may reduce the system activity and
lower the temperature as a result.
b) Plumbing single
acting systems as
double acting with
both A ports orificed
may reduce heating
b) Contact NORAC for more information
c) Depending on your type of system, other adjustments may be made.

 Boom(s) will not raise or lower
Possible Cause(s) Suggested Solution(s)
a) Poor cable
connection, defective
cable(s) or defect in
the NORAC valve
block
a-1) Check all cable connections between the
control panel and the valve block. Ensure
that they are tight and free of corrosion.
a-2) Check the LCD screen in which the valve
command arrows ("" or "") appear.
a-3) Measure the voltage at the valve
connection.
a-4) If there is no voltage, the cable(s) may
need repairing or replacing.
a-5) If there is sufficient voltage (+12V), and
the valve is not reacting, the valve may
need repairing or replacing
