1. System description

1.1 Areas of application

The Magphant flow monitor provides the plant system with the information needed onflowrate in the piping. The magnetic-inductive measuring principle determines theflow velocity of the conductive liquid at the tip of the sensor. Exceeding the presetswitchpoint (limit value) is indicated by a relay contact. An analogue 4...20 mA signalproportional to the flow is also available for monitoring the flowrate at the same time.The Magphant is ideal for process protection and monitoring.

1.2 Measuring principle

In accordance with Faradays law of magnetic induction, a voltage is induced in a con-ductor that is moved through a magnetic field. In the electromagnetic principle ofmeasurement the flowing fluid represents the moving conductor. The induced voltageis proportional to the flow velocity and is fed to the measuring amplifier by a pair ofelectrodes. Microprocessor-controlled electronics, with a stable zero-point, convert the voltageinto an analogue 4...20-mA output signal.

2.3 Mounting instructions

Orientation in the pipingThe Magphant is best mounted in vertical piping.If the piping runs horizontally, then the Magphant is to be mounted to the side.This mounting procedure ensures that the electrodes are always immersed in flowingfluid.

Caution!Never weld the weld stub to the pipe with the Magphant in place.

Position of the electrode axisThe sensor is to be mounted so that the electrode axis is always 90° to the direction offlow. The two PG 16 cable glands can be used as a visual check as these also lie onthe same axis.

Potential equalizationThe Magphant should be connected to ground via the ground terminal at the housingto ensure complete electromagnetic compatibility.

Note!Take care that the ground cable is kept as short as possible.

3.3 Commissioning

Before switching on the measuring system, the following checks should be carriedout:• Does the directional arrow on the Magphant agree with the actual flow direction,

i.e. do the two PG 16 cable glands lie at 90° to the direction of flow?• Check the electrical connections and terminal assignments as shown on Page 13.• Check that the local power supply agrees with the information stated on the name-

plate.

The following procedure should now be carried out:

1. Set miniature switch 1 (test mode) to the "normal" position (see Page 17).2. Set the miniature switches 2 to 4 for

– time constant / relay latch time– relay function– min. / max. fail-safeas appropriate.

3. After switching on the power supply, the outputs are deactivated for 5s (relay de-energised and current output remains at 0 mA). Both LEDs flash during this proce-dure.

4. Set the full-scale value. This can be done in two ways:Full-scale value with actual flow (local calibration)– Take into account general flowrates anticipated.– Turn the full-scale potentiometer until the green LED lights up (see Page 16).Setting the full-scale value without actual flow– Set the full-scale potentiometer at the mean flow rate anticipated.

5. Use the limit switch to set the relay switchpoint in % of the preset full-scale as described in Point 4.

Note!A detailed description of the display and operating elements is given on Page 15/16.

Description of function

Time constant / Relay latch timeThe times t = 3 s and t =10 s correspond to the current output time constant and also to the relay latch time.t = 3 s: The relay switches immediately and then remains

in this state for 3 seconds. t = 10 s: The relay first switches when the measured value

is below or above the limit value for a continuous 10 seconds.

Relay functionsThe relay is energised if all functions are operatingcorrectly. The relay is de-energised immediately when anerror or alarm occurs.

limitThe relay de-energises or the red LED lights up if thesignal moves outside the upper or lower limit value(depending on the min./max. fail-safe setting).

(limit) + errorThe same function as for "limit", but in addition:The relay de-energises if the flow rate is larger than themeasurable value of the Magphant or if an instrument erroroccurs. The red LED flashes. "Error" has higher prioritythan "limit".

5. Troubleshooting and Remedies

5.1 Response of the measuring system to faults

• Error messages which occur during measurement are always indicated via the current and, depending on the preset relay function, also via the relay output.

• In addition, a system or process error is always indicated when the red LED flashes.

5.2 Checking the electronics

The Magphant can be set to a test mode using miniature switch No. 1:

1. Set test mode switch to "test".2. Turn the full-scale potentiometer anticlockwise until it comes to the mechanical

stop, the current output must now be exactly 20 mA.3. If this is not the case, then the electronics module must be replaced.
