Supplement Section 6: Hydraulic cooler

The 1130 electric grinder is equipped with DC motor driven hydraulic oil cooler to provide supplemental cooling of
the hydraulic oil. The fan on the cooler is driven by a DC electric motor. The fan on/off and direction is regulated by a
controller based on the oil temperature. Air is sucked through a screen box which the cooler is attached to. Once the
oil is above 125°F the fan is turned on bringing air over the cooler fins. Debris is stopped by the screen as air passes
through to the cooler. If the screen plugs up and air flow is decreased to the cooler the oil will heat up, once the oil
reaches 170°F the fan will stop and then reverse for 30 seconds. The debris will be blown off of the screen and the fan
will resume in the forward direction. The fan will turn off once the oil temp falls below 105°F.
Indicator LED's
The controller has 2 LED's which display the system status. The green LED will light when power to the system is
applied and no errors are detected. The red LED will blink if there are faults to the output (fan motor). The output is
monitored for no-load or overload conditions. If a fault condition occurs, count the number of blinks of the red LED,
then refers to the error codes below:
RED ERROR CODE LED BLINKS:
Explanation:
1 The controller is overheating. Either the fan is drawing more current than it should, or the controller is
not being cooled sufficiently.
2 The fan is not connected. Check for broken wires. The minimum current draw must be 2A to keep the
system from showing an error.
