6.4 The Instrumentation

Your Maverick Boom utilizes instrumentation for certain decision-making activities. Listed below are the sensors included on this unit

•Tank Temperature sensor

•Charge pressure filter switch

•Valve pressure filter switch

•Return filter switch.

The tank temperature sensor monitors the fluid temperature in the area of the pump suction screens. The temperature is real time and is used on the network to accomplish certain objectives. The first, is to display on the interface while the cutter-circuit is operating. The second is to be used to control the electric fan on the hydraulic cooler. At any time the fluid level reaches 150°F the fan is activated and remains active until fluid level drops below the desired temp.

The Charge pressure filter switch is located at the filter in the charge loop on the hydrostatic pump. The sensor monitors the back-pressure created by the filter element when in use. When the back pressure reaches a setting of 50 psi the switch will trigger and prompt the operator for an element change.

The filter does not have a bypass, therefore the cutter circuit will be turned off by the electronic network. It will remain inactive until the filter is changed and the back-pressure at the filter is normalized.
