3.3 ELECTRICAL INSTALLATION

3.3.1 Input Power Requirements

F-3000 Electromagnetic Flow Meters equipped with advanced transmitters are available with two

different options for input power. This is not a user selectable function and must be congured at

the factory.

Special care is required to ensure that the F-3200 is properly connected to earth through an

earth wire. This connection is required to prevent random electrical noise from interfering with

the operation of the meter. (See section 3.3.3 for details.)

* Low Voltage: 18 – 45 VDC, 18 – 45 VAC 45/66 Hz, 300 mA maximum

* High Voltage (Mains): 100 – 240 VAC 45/66 Hz, 35 mA maximum

IMPORTANT NOTE

This option is not eld selectable. Contact the factory if you need to change the input voltage rating.

CAUTION/WARNING

This product must be connected to earth ground for proper operation. Failure to do so will result in

erratic operation and an increased risk of injury.

WARNING

All mains voltage connections must be made through pre-drilled conduit/strain relief opening

located at the bottom of the enclosure. Failure to do so will result in an increased risk of injury.

3.3.2 Analog and Pulse Output Signals

The primary output signals from ONICON F-3200 series electromagnetic ow meters include

a single analog output for ow rate and two programmable pulse outputs for use as frequency,

scaled pulse, alarm and ow direction signals. The three outputs have 500 VDC of electrical

isolation between the ow sensing circuitry, the microprocessor circuitry, and the pulse and

analog output circuitry. In addition, the output circuits operate from dedicated power supply

circuitry that is isolated from all other internal power sources and from earth.

Redundant Output Option

The redundant output option for the F-3200 series electromagnetic ow meter provides complete

signal redundancy for the three primary output signals from the meter. It provides an additional

4-20mA output and two additional programmable pulse outputs and is designed with the

same 500 VDC electrical isolation as the primary outputs. The redundant output transmitter is

controlled directly from the microprocessor and is completely independent of the primary output

circuitry.
