Programming
60 Hz to 80 Hz Operation
When installing the PENTEK INTELLIDRIVE with
a motor and liquid end of the same HP rating,
operate it at 60 Hz (the default value). The Drive
can be operated at frequencies of up to 80 Hz
when the installation uses a 3-phase motor 2 times
the size of the pump. For example, a 1 HP pump
with a 2 HP 3-phase motor. This combination
will equal the performance of a conventional
2 HP pump.
Press Main Menu and follow the keypress sequence
shown in Figure 11. Be sure to press ENTER to save
the new Max Frequency selected. The Drive will
now use the new value selected.
NOTICE The Drive will not allow the output amps
to go above the Service Factor Amps selected on
the keypad. Because of this, some 80 Hz operations
may be limited. This protects the motor and may be
a common occurrence in a 80Hz operation.
Keypad Lock - Password
The password locks or unlocks the blue buttons
on keypad. All PENTEK INTELLIDRIVE units are
shipped from factory with the default password
7777. It can be changed to any other 1 to 4 digit
number. To reset password to a unique password
for unit, unlock keypad (see below) and follow the
keypress sequence shown in Figure 12 to make the
change.
If installer does not press the password button, then
the keypad will automatically lock 60 minutes after
the Drive is powered up. The time out period is
adjustable (see Table 5).
To unlock keypad press Password, use directional
arrows to select numeric code and press ENTER.
NOTICE For more detailed information on keypad
functions, see Figure 2.
Pump Out Operation
(Verify Keypad is unlocked) Press Pump Out Key.
Drive will ask "Is The Valve Open?" and the default
answer "No" will be displayed. Press ENTER to
highlight "NO", use arrows to change display to
"Yes", press ENTER. The Drive will start pump in
a constant speed mode (default 45Hz). The pump
will run until STOP or Auto Start are pressed. If
speed change is necessary, press enter to highlight
value, use arrows to change value, then press enter
to save. NOTICE: Above ground pumps should run
at 60Hz for this step (until pump is primed). Then
adjust frequency as necessary.
Setting the Pressure
NOTICE Default pressure setting is 60 PSI. If this
value is changed, adjust tank pressure accordingly
(see Table 3).
The Over Pressure parameter may need to be
adjusted if the default pressure setting is increased.
Do not set the Over Pressure paramter above the
operating pressure of the pressure relief valve in the
water system.
There are three ways to change the pressure
setpoint:
1.
While running the pump
•
Follow keypress sequence shown in Figure
13 to make desired change. This parameter
allows either Internal or External Setpoint
to be changed, depending on which one is
referenced at the time the change is made.
2.
