Transducer
The PENTEK INTELLIDRIVE uses a 4-20mA, 0-100PSI pressure transducer to control motor speed (Drive settings may be changed to use a max 300 PSI transducer).
The transducer (see Figure 1) senses pressure in the pipe and converts it to an electrical signal. The Drive senses and processes the signal in the PID (Proportional, Integration, Derivative) control. When operating in AUTOSTART mode, the Drive increases and decreases the speed of the pump motor as needed to maintain constant pressure in the piping system.
Keypad
The keypad programs the Drive, monitors the status of the pump, and displays faults if they occur. Each button has a unique function, as described in Figure 2. The LCD display shows a text display of the status of the Drive’s operation. Other LEDs light up to indicate when certain buttons are pressed or certain events occur.
Fan
The Drive uses a thermostatically controlled internal fan which operates automatically when necessary to cool the Drive components.
Changes internal pressure setpoint from 15 PSI to transducer max -3PSI
(default is 60 PSI).
Runs the Drive (with no pressure control) to allow installer to pump out well.
Changes display to previous screen.

Wiring
To allow for ease of wiring, the enclosure wiring area is free of electronics other than the terminals. Conduit holes and knockouts are located so
that the wire can be fed straight through to the connectors, with minimal bending. The terminals accept 6-14 AWG wire.
Installations that require larger wire gauge than
6 AWG will require an external junction box. Run 6 AWG wire from the Drive into the junction box, then make external connections with wire nuts to appropriately sized wire.
NOTICE For convenience in wiring, the input and motor terminals unplug from the box. Pull them down to remove them for ease of access, as shown in Figure 8.
Verify that the terminal connectors are completely seated when you replace them. It is best practice
Figure 8 - Pull input and motor terminals down to remove, making wiring easier.
to connect all output wires (larger wire gauge) first, then all input wires.
Pump Connections
If the PENTEK INTELLIDRIVE is used with above ground motors (3-phase only) not rated for Variable Frequency Drive use, maximize motor life by limiting lead length to 25 ft. Refer to the pump owner’s manual, the National Electrical Code, and local codes for proper wire size.
The output of the Drive is single phase (2-wire or 3-wire) or 3-phase, depending on motor selection during startup.
The output power terminals (motor wire connections) are located on the lower right side of the Drive and are labeled R (Red), Y (Yellow), and B (Black). To select the wire size, multiply the wire length by 0.95 and then refer to the pump owner’s manual, the Nation Electric Code, and local codes for proper wire size.
NOTICE: Regardless of owner’s manual, wire LENGTH may not exceed 1000 ft. (305 M). NOTICE: 2-wire 1-phase connect to Y+B, not R+B.
Feed the motor cable through the 3/4” conduit hole on the bottom right side and into the appropriate terminals. If the wire is large enough to require a larger conduit hole, remove the 1-1/4” knockout and use the appropriate conduit connections. Attach the motor ground wire to the grounding screw, located on the grounding bar. Attach the motor power wires to the terminals as shown in Figure 9.
NOTICE Drive does not sense motor temperature and will not protect motor from over heating.

Pressure Tank Recommendations
Minimum tank size is two gallons. Use a precharged pressure tank with Drive, as shown in Table 3. The tank size must equal at least 20 percent of the pump’s rated flow in gallons per minute (GPM), but cannot be less than two gallons capacity. For example, a pump rated at 7 GPM would require a tank of two gallons capacity or larger. A pump rated at 50 GPM would require a 10 gallon tank or larger. Tanks larger than 10 gallons can be used, but may require adjustment of Wake Delay parameter.

NOTICE Set pressure tank’s pre-charge to 70 percent of the system operating pressure. When using an external set point as well as an internal set point, pre-charge tank to 70 percent of the lower setpoint of the two. Some applications may require a different percentage when determining the setpoint.
Transducer Connections
A 0-100 PSI 4-20 mA transducer is provided with Drive. Install the transducer downstream of tank, as shown in Figure 1. Install transducer in a tee in a straight section of pipe with at least 1 foot of
straight pipe on each side of the tee (i.e., all fittings must be at least 1 foot away from transducer).
Feed transducer cable through the open 1/2” conduit hole on bottom of the Drive enclosure.
As shown in Figure 9, connect the red wire of the transducer cable to AI+, connect black wire to AI–, and connect the cable shield to the metal cable shield screw.
To connect the transducer wires:
1.Strip wire ½ inch
2.Push spring terminal up with finger or slotted screwdriver
3.Insert wires from bottom
4.Release spring terminal
Input Power Connections
The input power terminals are located on the lower left side and are marked L1 and L2 (see Figure 9). There is a ground screw for the input ground wire to the right of the connector (torque to 10 inch lbs). Feed wire through the 3/4” conduit hole on the bottom left side and into appropriate terminals. If wire is large enough to require a larger conduit hole, remove the 1-1/4” knockout and use appropriate conduit connections.
To determine the correct wire sizes for installation, see Table 2.
NOTICE The PENTEK INTELLIDRIVE only accepts 230V single phase input power. If incoming power does not match this, have a qualified electrician alter supply voltage to 230V/1Ph before connecting it to the Drive.

3.Pump out well (if necessary):
Direct pump’s discharge to appropriate location not connected to system and press Pump Out. The pump will run at 45 Hz.
Adjust frequency as appropriate:
A.Press ENTER
B.Change frequency value
NOTICE Above ground pumps should run at 60 Hz for this step (until pump is primed). Then adjust frequency as necessary.
C. Press ENTER again.
Run the Drive in this mode until the well discharge runs clear, then press STOP button to stop Drive.
Risk of explosion. In Pump Out mode, pump runs at a constant speed, which can cause very high pressure if flow is restricted.
4.Verify installation: Make sure that the system has properly-sized, pressure-relief valve and pressure tank.
Make sure pressure tank’s precharge is correct. See Table 6.
Make sure pump discharge is connected to system.
Service Factor Amps
To maximize pump performance, be sure to enter the correct Service Factor Amps (SF Amps) in the PENTEK INTELLIDRIVE.
•Entering SF Amps higher than the motor rating lets the Drive supply more amps to the motor than the motor is designed for and may allow the motor to overheat (see Table 4).
•Entering SF Amps lower than the motor rating limits the output amps to less than the motor is designed for and will reduce the performance of the pump.
•For any 1-Phase 3-Wire motor, the correct Service Factor Amp rating for the Drive is Cap Start/Cap Run amps (see Table 4). This may not match the motor nameplate, which (for a Single Phase, 3-Wire motor) will generally be Cap Start/ Induction Run Amps.
•For any 3-Phase or 1 Phase, 2-Wire motor, use the motor nameplate Service Factor Amp rating.
NOTICE PENTEK® submersible motors may differ from motors of the same horsepower from other manufacturers. For 1-Phase, 3-Wire motors from all other submersible motor manufacturers, enter the motor manufacturer’s CS/CR service factor amps for your motor.
For 3-Phase or 2-Wire 1-Phase motors, use the motor nameplate amp value. Also see Retro Fit Applications. (Table 7)
5.System Start:
A.Open valves at the ends of lines so that air will escape during pressurization.
B.Press Auto Start; close valves at the ends of lines after all air has escaped.
C.The system goes into Constant Pressure Operation as soon as the transducer registers the Dry Run Sensitivity parameter (default
is 10 PSI). If system pressure does not reach that PSI value within 3 minutes, the Drive will stop. Press Auto Start again to restart line fill. If longer priming or line fill time is required, adjust Fill Time parameter. See Table 5.
Changing a Parameter Value
This procedure works for ANY parameter.
A.Press MAIN MENU button.
B.Follow the keypress sequence shown in Figure 12:
A shorthand way to remember this is:
•Press ENTER to highlight a value
•Use arrows to change valve
•Press ENTER again to save it
•If new value is not saved, any screen change will result in the loss of the new value.
Table 5 lists all available commands and parameters for the PENTEK INTELLIDRIVE.

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.Via the PSI Preset (Shown in Figure 14).
3.Via the Main Menu (Main Menu/Settings/ Setpoint/Internal Setpoint)

I/O Connections |
16 |
4.The I/O terminals are located in the center of the wiring compartment, as shown previously in Figure 9.
The Digital Input connections (I1 and I2) are used to control the Drive based on the state of an external device, such as a flow switch, moisture sensor, alternator, or other device. Programming is needed to activate any of these functions (see Table 5).
The Output Relay (O1) is used to control an external device based on two states of Drive; either Running the pump or Faulted. Programming is needed to activate any of these functions (see Table 5).
Cable Installation
Three 1/2” conduit knockouts are provided on the bottom of the Drive enclosure for the I/O wires.
Break out the closest 1/2” knockout and route the wires through. Use a cord grip to prevent the wire from rubbing and causing a short.
NOTICE Never run low voltage I/O wire through the same conduit hole as the 230V input wires or motor wires.
To connect the external wires to the terminals:
1.Strip wire ½ inch
2.Push spring terminal up with finger or slotted screwdriver
3.Insert wires from bottom
4.Release spring terminal
Connection Examples
Figures 15-18 show various connection schemes for typical applications. Table 6 describes each I/O terminal, including purpose and rating.

RS-485 Communications
RS-485 is a US-based telecommunications standard for binary serial communications between devices. It is the protocol, or set of specifications, that needs to be followed to allow devices that implement the standard to speak to each other.
A fully compliant RS-485 port is included in the PENTEK INTELLIDRIVE system to permit serial connections among more than two devices on an RS-485 compliant network. Figure 19 shows twowire connection to the Drive.
