A. If the actual APR displaying on console fluctuates more than 5% above and below the target APR while the vehicle maintains a steady speed, the hydraulic adjust should be investigated. Corrective action: 1. Re do a hydraulic adjust. 2. Check APR sensor for loose coupling or slipping on shaft.

A: If the actual APR desplaying on the console is slow respinding to ground speed or target APR changes or stabilizes at the wrong value, the hydraulic adjust may require fine tuning. Corrective action: 1. Re do a hydraulic adjust.

A: Corrective Action: 1. Check PWM offset and saturation points. Contact DICKEY-john for more information. 2. Check for variations in granular material density dropping onto the spinners from the conveyor/auger. 3. On Proportional valves, increases in electrical coil resistance due to heat buildup can cause valve. 4. ON servo valves, increases in hydraulic fluid temperature heats the valve and results in speed variations. 5. Check for drag due to snow and ice buildup.

A: Corrective Action for Granualr System: 1. Reduce the truck ground speed to allow the system to catch up and the error to clear. 2. Shift to a lower gear to increase engine RPM and hydraulic pump rotation. 3. Check hydraulic disconnects and filter. 4. Ensure correct spreader constant is programmed. Redo a drop test (F6). 5. Inorrect PWM saturation point. See (F3) and/or Redo a system response (F11) 6. Check for insufficient hydraulic oil flow at normal engine RPM. 7. Check spreader valve, electrical connections to the valve coil.

A. Redo a ground speed calibration, if the doesn't work check and/or replace speed cable.

A. Corrective Action: 1. Inrease engine RPM 2. Try to do a calibration on the channel that will not finish the system response. If the calibration does not count pulses check connections to the sensor, and replace if all connections and wiring are ok.

A: Push and hold display/select until calibrate shows in the bottom left hand portion of the screen.

A: Push and hold display/select until calibrate shows in the bottom left hand portion of the screen, push display/select one more time to until you read program at the bottom left hand corner.

A: On your harness, there is a printer plug, if the dummy plug has fallen off you will not have any sound.

A: From the calibrate menu, push display/select to scroll to hyd. Adj, turn the off auto unload switch to auto, engage hydraulic system, rev engine to 2000 rpm’s, push down arrow to start run until process completes.

A: From the calibrate menu, load a known amount of material into bed, push display/select to scroll to spr.adj, push display/select one more time until you get 6 zero’s in the display, push start to unload material, after material is ran out enter weight in.

A: From the calibrate menu, press display/select until type is on the display, press the down arrow and the number will be displayed.

A: From the calibrate menu, press display/select until you see manual on the right, push the up button so the display says yes(works to turn off manual also).

A: APER means that the valve is wide open and cannot get enough material out.

A: Manual means the ICS is not getting feedback from a sensor, verify that the application rate sensor is sending back pulses and the speed signal is present.

A: Yes, however DICKEY-john recommends that you always hook DICKEY-john systems direct to the battery.

A: If the spreader/sprayer does not function when the MASTER switch is in AUTO but does in the UNLOAD postion, the ground speed sensor may have failed. Corrective action: 1. Check the ground speed reading (MPH) on the console. If the ground speed reading is 0 when the truck is moving; a. Check wires and connections between the DICKEY-john ground speed sensor and the console b. Check wires and connections between the DICKEY-john ground speed sensor the transmission 2. Check the ground speed calibration number programmed in the console. Compare the number to the original setting. Typically, the constant should be between 35,000 and 60,000. 3. Next replace the ground speed sensor. 4. If the failure continues, replace the MASTER switch and then the console. Note: The ICS 2000 system can continue operating without a "true" ground speed sensor input by setting the MANUAL SPEED to YES in the Program mode. To spread/spray in this mode, set the MASTER switch to the AUTO position and drive truck at the displayed SPEED. To stop spreading, change the MASTER switch back to the OFF postion.

A: If the words "MANUAL MODE" are flashing on the display, the ICS 2000 system may have reverted to the manual override function to compensate for a sensor failure (conveyor/auger sensor). If so, the system is operating in open loop control to allow spreading to continue until sensor repair/replacement is possible.

A: Corrective Action: 1. Check for blown fuse, located in positive battery lead. If blown, replace with blade-type 20 Amp fuse. 2. Check for poor connections to the battery; remove any corosion. Also check battery polarity. 3. Check the red ignition wire. 4. Visually inspect power cable from rear of console to battery. If damaged, replace cable/repair. 5. If no problem can be found with power connection or power cable, console may be at fault.

A: Corrective Action: 1. Check spreader constant. 2. Constant may be too low for the amount being applied. 3. Lower gate and redo a drop test. 4. Increase rate to see if belt smoothes out, or increase speed, if this works redo a drop test. 5. Manually overide the valve a couple times to verify it is not sticking. 6. Check voltage to valve to verify it is not varying. 7. Replace coil and/or valve.
