There are a number of special keys used in WellTimer Pro to provide quick access to various settings and informational views. The F1-F10 keyboard function keys are used as well as ESCape and 'q'uit.
F1-F8 Pump Configuration
These keys enable the Pump Configuration screen. F1 configures pump #1 while F4 configures pump #4. If you have fewer than 4 pumps enabled then some of the respective function keys will not be shown. Use the Up and Down arrow keys to move between fields in the Pump Configuration screen
ALT_F1-ALT_F8 Manual Pump Control
Pressing this key toggles the pump output control on and off. ALT-F1 controls pump #1. ALT-F2 controls pump #2... This is a good way to test computer communication as well as physical hookup. It can also be used for sample collection to turn on a specific pump. Every 5 minutes all pump states are updated to reflect the pump plan so it is not possible to leave a pump on accidently.
F9 System Configuration
This key enables the system configuration screen. The system configuration screen allows entry of various system wide parameters which affect operation of all well pumps. Use the Up and Down arrow keys to move between fields in the Pump Configuration screen
F10 Done
This key is used to exit any of the configuration screens. When F10 is pressed a new pump plan is computed and displayed based on any changes made to the configuration.
? Help
This key brings up the help system.
ALT_F10 Daily Tides / Pump Plan
This key toggles between a display of the daily pump plan and a list of the high and low tides for the next week. Due to the intensive numeric computations required for high/low tide computations, use of this key on a 100LX or 200LX is not recommended.
ESC Escape or Abort
This key will terminate any active configurations screens, discarding any changes. This key should be used if you decide you do not want any changes you have made to the configuration to become effective.
q Quit
The 'q' key is used to quit the WellTimer Pro program.
Pump Parameters are accessed by pressing F1, F2, F3, or F4. After pressing one of these function keys a window will be shown which shows the current settings for the pump you have selected. These parameters specify information required by WellTimer Pro to decide when the pump should be used. If you make a mistake and want to cancel any changes, press the ESC key. When you have completed your changes you should press the F10 ('Done') key. The following fields are currently supported:
Name
This is the local site name used for pump #1. This name has no significance to the WellTimer Pro program and is provided as a mnemonic assist to the operator.
State
This field enables or disables a pump from operation. When set to '0', the pump is disabled. When set to '1', the pump is enabled.
Rate
This field specifies the current pump rate in gallons per minute.
Max On
This field determines the maximum number of minutes that a pump should be able to pump without 'resting'. When 'Sequential' pump mode is selected, this will cause the system to select the next pump in sequence when the Maximum ON time has expired.
Min Off
This field determines the minimum time a pump will stay off once it is turned off.
Priority
The priority field is only used when the system configuration Pump Algorithm is set to 'Parallel'. The Priority number is a number between 0 and 100% which determines the percentage of the total pump time to be allocated to this pump. For example, if one pump was set to 100% while another was set to 50%, the pump set for 50% would only pump half as much as the pump set to 100%. This field can also be thought of as specifying the duty cycle of the pump on time during Parallel Pumping. If all pumps are of equal priority, use 100%.
The System Configuration Parameters are accessed by pressing the F6 key. When F6 is pressed, a window will appear which allows you to configure the following parameters. If you make a mistake and want to cancel any changes, press the ESC key. When you have completed your changes you should press the F10 ('Done') key.
Number of Pumps
This is the total number of pumps to be controlled.
System Limit
This is the maximum pump rate of the system, sometimes referred to as the water right.
Tidal Lag
This is the lag between the actual time of low tide and the time the low tide is noticed at the well head as a change in static level. This can often be determined from measurements taken during a 24 hour draw down test.
Daily Estimate
This is an estimate of the total daily gallons required by your system. A good rule of thumb is to use a value which is 10% more than your actual needs. This will minimize pumping while insuring that your water level does not decrease faster than it is restored by pumping.
Pump Algorithm
This parameter specifies either 'Parallel' or 'Sequential' pump mode. In 'Parallel' mode, all pumps will pump at once while in 'Sequential' mode, only one pump will pump at a time.
Timer Mode
This parameter specifies either 'Tidal', 'Clock', or 'AutoClk' based pumping activity. When 'Tidal' is selected, the pump algorithms are adjusted so that the bulk of the pumping is done at low tides. When 'Clock' mode is selected, pumping is constrained to occur between the start and stop time specified in the system configuration screen. The off time of each pump is strictly enforced. When 'AutoClk' is selected, the pump activity is spread out over the specified start and stop time according to the amount of pumping required to fulfill the daily pumping needs.
Clock Start
This specifies the start time for pumping when 'Clock' or 'AutoClk' Timer mode is selected.
Clock Stop
This specifies the stop time for pumping when 'Clock' or 'AutoClk' Timer mode is selected.
COM Port
This parameter specifies which communications port of the computer to use for controlling the pumps. Use '0' (none) if your computer is not actually controlling pumps.
Battery Type
This parameter specifies the type of battery installed in the palmtop computer. NiCad batteries are recommended and are charged when the computer is on. By using NiCad batteries, you can insure that the computer will restart after a power failure.
System Time
Use the parameter to set the system clock of the computer.
System Date
Use the parameter to set the system date of the computer.
