Controller for Pumps
ENTEK PG500 series pump controller controls,
protects and automates single pump applications.
Complete
solution for single pumps
Microprocessor-based
controller protects against dry running of pumps without
the need for level switches or level floaters
Protection
for short circuit, over-current and phase-loss
Waterproof
on-off switch
PG500 controller
can also be used to control the tank water level with a
floater switch input, or the tank pressure with a pressure
switch
Automates
applications for a more reliable and economical solution
Delay feature
prevents frequent start-stops
LED indicators
for Alarm and In Operation signal
LED indicators
for High and Low Levels
Manual override
of automatic functions
NEMA12 Enclosure
Single-phase and three-phase
systems: PG500 is used for the control of up to 1.5kW single-phase
or up to 4kW three phase direct online connection pumps.
Single-phase motor capacitor can be placed in the controller
box.
Standard configuration allows the use of pressure sensor and
level float switch inputs.
Standard controller can be used
for water level control with a float switch. It is also possible
to connect a pressure switch to the controller, so that the
pump can be used to automatically control the line pressure.
All measurement and control functions
are processed by a microprocessor. In case of a dry running
condition, the controller stops the pump. It can restart the
pump after a delay set by the user. In case of an over current,
the controller stops the pump and waits at that state for
a manual restart for safety reasons.
Main functions:
Turns the pump
on or off
Protects the motor
against over current
Protects against
phase loss
Short circuit
protection
Pump protected
against dry running
Automated operation
with added external pressure switch or level float switch
2 Contact outputs
for external monitoring of the controller
Operating Modes and Indicators
A 3-way switch
located on the electronic card selects between three
operating modes: Automatic, Manual On or Off.
LED signal lights
indicate: Power on, Operating, Failure, Protection Mode,
Pressure High/Low
