Operation / Programming
2.
Pump out the well (if necessary):
Direct the pump's discharge to an appropriate
location not connected to the system and press Pump
Out. The pump will run at 40 Hz.
Adjust frequency as appropriate:
A. Press ENTER
B. Change frequency value
C. Press ENTER again to save the value.
Run the drive in this mode until the well discharge
runs clear, then press the 'Stop' button to stop the
drive.
Hazardous pressure. In Pumpout
mode, the pump runs at a constant speed, which can
cause very high pressure if flow is restricted.
3.
Check List:
Make sure that the system has a properly sized relief
valve and pressure tank.
Make sure that the pressure tank's precharge is
correct. See Table 4, Page 7.
Make sure that the pump discharge is connected to
the system.
4.
System Start:
Open valves at the ends of lines so that air will escape
during pressurization.
Press Auto Start; close valves at the ends of lines after
all air has escaped.
The system goes into Constant Pressure Operation as
soon as the transducer registers 70 kPa. If system
pressure does not reach 70 kPa within 3 minutes, the
drive will stop. Press AutoStart again to restart line fill.
If a longer priming or line fill time is required, adjust
the 'fill time' parameter in the 'dry run' menu
(Page 11).
ADVANCED PROGRAMMING
Locking & Unlocking the Keypad
Password: The password locks or unlocks the blue buttons
on the keypad. All PENTEK IntelliDrive units are shipped
from the factory with the default password '7777'. It can
be changed to any other 1 to 4 digit number. To reset the
password to a unique password for your unit, unlock the
key pad (see below) and go to "SETTINGS/Password",
Page 10.
If the installer does not press the PASSWORD button, then
the Keypad will automatically lock 60 minutes after the
drive is powered up. The timeout period is adjustable
through the Main Menu/Settings/Password.
To unlock the keypad press PASSWORD, use the
directional arrows to enter the proper numeric code, and
press ENTER.
NOTE: For more detailed information on Keypad functions,
see the "Parameters" section.
Changing a Parameter Value:
NOTE: This procedure works for ANY parameter.
1. Find the parameter and display the current parameter
value on the screen.
2. Press ENTER to enable editing of the parameter.
3. Use the UP, DOWN, LEFT, and RIGHT arrows to
change the parameter values.
4. Press ENTER again to save the new parameter value.
NOTE: A "shorthand" way to remember this is:
• Press ENTER to change a value;
• Press ENTER again to save it.
• If you don't save the new value, then as soon as you
change the screen, you lose it.
Keypad Access Parameters
Pump Out Speed: Press Pump Out. The Drive will start the
pump in a constant speed mode (default 40 Hz). The pump
will run until you push Stop or Auto Start. If necessary to
change the speed, Follow steps 2-4 above to change the
parameter.
Pressure Setpoint: Press Auto Start, then follow steps 2-4
above to change the parameter. Use the directional arrows
to change the pressure.
• NOTE: This parameter allows you to change either the
Internal or the External Setpoint, depending on which
one is referenced at the time you are making the change.
• NOTE: To change the setpoint before starting the pump,
go to the Main Menu/Settings/Setpoints/
Internal Setpoint.
• NOTE: If this value is changed from the default value of
400 kPa, you must adjust the tank pressure accordingly
(see Table 4, Page 7).
PSI Preset: Press PSI Preset; follow steps 2-4 above to
change the parameter. The default is 400 kPa, but the para-
meter can be set to 300, 400, or 700 kPa.
Language: Press Language; follow steps 2-4 under
"Changing a Parameter Value," Page 9, using the UP or
DOWN arrows to scroll through the available languages
(English, French, or Spanish; default is English).
• NOTE: To change the setpoint before startup, go to the
Main Menu under "Settings".
Main Menu Parameters
The Main Menu has six secondary menus (plus a Reset)
that allow access to the Advanced Programming
parameters: 1) SETTINGS, 2) MOTOR, 3) SENSOR, 4) PIPE
BREAK, 5) DRY RUN, 6) I/O. The basic structure and
navigation instructions are listed below. Use the UP and
DOWN arrows to scroll to the next secondary menu or
