Description 5
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.
