1.1 Getting Familiar With The Console The monitor console has a 185 segment Liquid Crystal Display which is backlit for visibility under low ambient light conditions. Figure 2. Front Plate of Seed Hawk Monitor The display can be broken into different display regions as follows: Function Indicators The triangle shaped segments on either side of the display indicate the selected display function. These function indicators will flash when alarm conditions associated with that function are present.
Display Line 2 The lower display line is designated line 2. It consists of five 7 segment numeric characters. It is used primarily for displaying numerical values for the selected function, and alarm conditions. This line also gives information during Change Settings modes and initial system installation. Bin Level Three 10 segment bar graphs indicate bin levels of up to 3 bins. The graphs indicate whether a bin level is in alarm.
2.0 STARTUP AND SYSTEM INSTALLATION 2.1 Normal Startup Normally, when the unit is powered on, the following display sequence takes place: x All of the display segments turn on one at a time, and then off one at a time. x “HAWK” is briefly displayed. x The Version/Issue number of the monitor software is displayed. This number should be included with any reports of faulty or unexpected system operation.
2.3 First Time Installation (Sensor LEARN Mode) When configuring a system for the first time, when upgrading a system with new sensors, and possibly after a rare system failure in which the loss of configuration information occurred, a Sensor Learn operation is required. Since the system configuration is saved in the monitor’s memory, only the monitor used during installation will operate properly on the system. When a new monitor is installed the system installation procedure must be repeated.
3. Now the monitor will display “MISSED” alternating with “FAN 1”, indicating that the first fan sensor may now be connected. Connect the fan sensor. 4. The process is the same for rest of the sensors in the sequence. When the monitor requests a sensor that will not be used in the configuration, press the OK key. The sensor will be assigned a disabled status, and the monitor will prompt for the next one in the sequence.
Now that you have completed the Learn Mode, to have a fully functional monitor you must continue with the set up procedures in section 3.0 to have a fully functional monitor. 2.4 Startup Error Messages In rare circumstances certain fault conditions may be detected at startup. This includes various conditions that the monitor checks for after the Version/Issue startup display.
3.0 Set Up Mode/ Change Monitor Settings Most of the function positions have settings that may be changed at the console. These include various configuration details, alarm trip points, and some convenient options such as whether imperial or metric units should be used for numeric display. 3.1 Common Operations for Change Settings Mode The next two subsections explain the procedure for entering and exiting any of the Change Settings modes.
3.1.2 Exiting from any Change Settings Mode 1. Press MODE until the "SAVE" display appears on Display 1. 2. If settings should be saved, press UP to choose yes (Y). Then hold down OK until after the long beep following four short beeps. 3. If settings should not be saved (but remain as they were before the mode started) press DOWN to choose no (N). Then press OK and mode exit occurs immediately. 3.
When the 400 feet has been driven, the operator can press the MODE key once again to stop the pulse counting. This will bring up a standard SAVE screen. To save, select Y and then press and hold OK until after the long beep. However, if the new count is less than 50, the existing count is not replaced. To discard the changes, select N and then press the OK key. 3.
The actual alarm point is set by physical position in the bin. Still, LEVEL should be set to agree with the sensor location. In this way, during alarms, the dividing point on the bargraph between the solid and blinking sections is a valid indication of the approximate level. The LOSHFT alarm will come on when the shaft speed drops below the alarm point pre-set by the operator. 3.4.1 Shaft Rate Calibration The procedure is to seed for an appropriate length of time while collecting the seeded material.
DISPLAY FUNCTION COMMENTS REVS Counts the number of revolutions the shaft has turned Drive short distance and collect material seeded. WEIGHT Enter Weight of material collected Use UP and DOWN to enter weight in pounds (kg). WT/REV Calculated weight per revolution of the shaft. Weight divided by number of revolutions SAVE Y Select whether to save the calculated application rate UP selects for Yes, DOWN selects for No. START 3.
4.0 NORMAL OPERATION 4.1 Function Selection and Display 4.1.1 General Comments and Summary of All Functions The descriptive text on either side of the display shows the names of all display functions on the monitor. The operator controls which function will be active using the UP and DOWN buttons. The triangular indicator will indicate which function is active. A descriptive function name will also appear on Line 1. Figure 3.
Following is a summary of what is displayed under each function. Some functions are discussed later in more detail. FUNCTION LINE 1 TEXT SPEED FAN 1 FAN 2 RATE SPEED FAN 1 FAN 2 RATE 1 RATE 2 RATE 3 SHAFT1 SHAFT2 SHAFT3 FAREA TAREA SHAFT 1 SHAFT 2 SHAFT 3 FIELD AREA TOTAL AREA WHAT APPEARS ON LINE 2 Ground speed Fan speed of the named fan. Application rate of the named metering shaft Shaft speed of the named metering shaft Area covered while seeding since the last time the counter was zeroed.
In order to exit SCAN or MANUAL mode, press the OK key. The top line will briefly flash the message “RATE” and then revert back to the default display where the UP and DOWN keys will change to other display types (such as FAN 2 or SHAFT1). When the monitor is no longer “In Motion,” the displayed rate is set to 0. 4.1.4 Bin Level Function For the BIN LEVEL function, instead of a selectable display position, the status of all bins is always shown on the bar graphs.
The user can press the OK button to acknowledge the alarm, which (if there are no other alarms pending) results in the silencing of the beeper and the return of the normal display. After acknowledgement, the indicator icon (or the upper portion of the bargraph in the case of bin level alarms) will continue to flash for as long as the alarm condition is present. If more than one alarm occurs at the same time, pressing the OK button will acknowledge each alarm in order of priority.
Various monitor actions depend on whether the monitor considers the drill to be active. These decisions are described in other sections of this manual, but an example is whether to generate an alarm for a stopped shaft. Seeding should be active when the track drive has been coupled to the ground drive wheel. The monitor determines whether the system is intentionally active by examining the ground speed. This is obtained from the ground speed sensor.
x Low Bin Levels (set by physical position of Lo/Hi Sensors) Bin Level Alarms Bin level alarms use the bargraphs and so are an exception to the above. There is still a Line 1 message and beeping, but instead of a triangular indicator the bar itself indicates the alarm. The lower portion of the bar remains solid, while the upper portion will flash. When a new alarm condition arises, the beeper will sound, the appropriate triangular indicator will flash, and Line 1 will indicate the fault condition.
4.2.5 Sensor Communication Alarms These alarms occur when a sensor does not respond to repeated attempts at communication by the monitor. The monitor display will alternate between the following: Line 1: Line 2: “COMERR” and (blank) where is the number of the faulty sensor. This number matches the number that appeared when that sensors was learned or woken up.
Field area is stored to a maximum of 9999.9 before rolling over to zero. Total area rolls over at 99999 acres. When displaying area in hectares, the display will roll over at 4047.0 Ha (field) or 40470 Ha (total), which are the metric equivalents of the rollover points. The operator should note that the area accumulation accuracy depends on a number of variables such as overlap, turns on the headlands, and how often the track drive is disengaged.
4.4 Sensor Replacement The monitor will alarm the operator if there is a faulty sensor in the system (see section on Communication Alarms). To replace a single faulty sensor, the replacement sensor is plugged into the harness prior to turning on the system. When the power is turned on, the monitor will learn the new sensor and replace the faulty sensor with it. This procedure will only work when there is one new sensor in the system.
