is preconfigured at 15 psi. The analog input AI53 is configured for a 40 psi
pressure transducer.
Set-up 2 Flow control with wired flow transducer. The controller setpoint is preconfigured
at 150 GPM. The analog input AI53 is configured for a 300 GPM flow transducer.
Set-up 3 Sensorless pressure control The controller setpoint is preconfigured at the
factory based on the order request.
Set-up 4 Sensorless flow control. The controller setpoint is preconfigured at the factory
based on the order request.
• Set-up 3 is the active set-up for the factory default configuration.
Enclosure rating
WARNING:
The enclosure rating of the controller must be maintained by using the appropriate wire
or conduit connectors and installing the controller in the appropriate environment. Failure
to use the appropriate connectors or to install in the appropriate environment may create
a dangerous condition and will void the warranty.
• The standard enclosure rating for the controller is IP55 or NEMA12.
• The controller is intended for indoor use only.
• Ensure the installation environment complies with the controller rating.
• Make sure all cable glands and unused holes for glands are properly sealed and the
cover is properly installed.
• Ensure that the system is installed in an environment that complies with the motor
ingress protection rating. Refer to the motor IOM manual for details.
Ambient temperature
WARNING:
The ambient temperature rating of the controller must be maintained by installing the
controller in the appropriate environment. Failure to operate the controller in the
appropriate environment may create a dangerous condition and will void the warranty.
• To ensure proper cooling of the controller, there must be adequate space above and
below the controller chassis. Refer to the Technologic Pump Controller IOM for
details.
• The controller can be operated with full load output current at maximum ambient
temperature up to the maximum altitude of 1000 m above sea level. For altitudes
above 1000 m, the maximum output current and/or maximum ambient temperature
must be derated. Refer to the Technologic Pump Controller IOM for details. Contact
the factory for installation above 2000 m.
