Temperature
Hydraulic fluid temperature alarms
A sensor monitors the hydraulic fluid temperature in the tank. Increased temperature can
mean that there is a problem with the cooling system.
Hydraulic fluid that is too hot is thin, which can accelerate wear on the parts, increase the
formation of sludge, degrade the fluid, and decrease its lubrication and protective qualities.
Hydraulic fluid that is too cool is thick and causes increased friction and poor lubrication.
High altitude and ambient air temperatures can have an effect on the temperature of
hydraulic fluid.
When the hydraulic fluid temperature is 55°C
(131°F): • At 45°C (113°F), a switch closes to start the
cooling fan.
• The operator interface shows W

>55C.
• The beacon light flashes amber.
• The fan operates for 10 minutes.
• If the hydraulic fluid temperature is lower than
55°C (131°F) after 10 minutes, the fan turns
off.
• If the hydraulic fluid temperature is higher
than 45°C (113°F) after 10 minutes, the fan
continues operating.
