• If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property may occur.
• The manufacturer assumes no liability or warranty for any consequences caused by tampering with the product or incorrect use by the operator.
• Installation, electrical connection, set-up, operation and maintenance of the product must be carried out by qualified personnel authorised by the machine operator.
• Protect units and cables against damage.

Intended use

• The device monitors liquids and gases.
• The device detects flow based on the calorimetric measuring principle and switches the output.
• The switch point is adjustable.
• The typical response time of the device is 1 … 10 s. It can be influenced by the setting of the switch point:
• Low switch point = quick reaction with the rising flow.
• High switch point = quick reaction with the falling flow.

Installation

CAUTION

• During installation or in case of mechanical failure, high-pressure or hot media can leak from the system.
• Risk of injury caused by pressure or burns.
• Ensure that the system is free of pressure during installation.
• Ensure that no media can leak at the mounting location during installation.

Installation position

Immersion depth

• The sensor tip must be completely surrounded by the medium.
• Recommended immersion depths: minimum 12 mm.

Recommended mounting position

• For horizontal pipes: mounting from the side.
• For vertical pipes: mounting in the rising pipe.

Conditionally possible installation position

• For horizontal pipes, if the pipe is free from build-up: mount from below.
• For horizontal pipes, if the pipe is completely filled with medium: mounting from the top.

Impermissible installation position

• The sensor tip must not be in contact with the pipe wall.
• Do not mount in downpipes that are open at the bottom.

Interference

• Structures in the pipe, bends, valves, reducing pieces and the like affect the function of the unit.
• Adhere to the distances between the sensor and interference.
• D: Outside diameter of the pipe
• S: Interference

Process connection

• Using process adapters the unit can be adapted to different process connections.
• A correct fit of the unit and ingress resistance of the connection is only ensured using of adapters.
• For small flow rates, if adapter blocks are available.
• The device is supplied without accessories.
• Information about available accessories is at documentation.ifm.com.
• The optimum function is not ensured when using components from other manufacturers.

1. Process connection
2. Adapter
3. Sensor tip
4. Coupling nut

• Grease the threads of the process connection, adapter and sensor. Use a lubricating paste which is suitable and approved for the application.
• Ensure no grease is applied to the sensor tip.
• Screw the suitable adapter into the process connection.
• Place the flow monitor onto the adapter and tighten the nut. Tightening torque 25 Nm. Ensure that the unit is correctly oriented.

Electrical connection

• The unit must be connected by a qualified electrician.
• Observe the national and international regulations for the installation of electrical equipment.
• For the output, the circuit takes the same protective measures as the supply circuit.
• Insert a miniature fuse according to IEC 60127-2 Sheet 1 ( ≤ 5 A fast acting).
• Disconnect power.
• Connect the unit as follows:
• BK: Black
• BN: Brown
• Caption: Blue
• WH: White
• Do not connect pin 5.

Operating and display elements

1. Operation indication
   • The LEDs 0…9 represent the range of the monitored flow.
   • The green LEDs show the current flow.
   • An illuminated LED shows the position of the switching point:
   • Orange = output closed
   • Red = output open
2. Setting buttons for adjustment and configuration

Set-up

• Switch on the supply voltage.
• All LEDs light and go out again step by step. During this time the output is closed.
• The device is in operating mode.

Settings

• The switch point is preset Ò Technical data is at www.documentation.ifm.com.
• The preset switch point can be changed.

Switch point setting

• Changing the preset switch point is useful in the following cases:
• The flow fluctuates strongly or pulsates.
• A faster response time for the device is required.
• Low switch point = quick reaction with the rising flow.
• High switch point = quick reaction with the falling flow.
• Briefly press [▬] or [+].
• All LEDs are off.
• Press [▬] or [+] as often as required.
• Each press of the pushbutton shifts the flow by one-half LED in the indicated direction.
• As soon as a button is pressed, the LEDs are switched on. The LEDs of the current process value are flashing.
• When the required switch point is reached, do not press the button for more than 2 seconds.
• The device goes into operating mode with the newly set value.

Teaching the switch point

• The switch point can be set to the current flow value (flow adjustment).
• Let the required flow to pass through the installation.
• Press the [▬] button for at least 15 seconds.
• LED 0 and LED 9 first light up green, then flash green.
• Release the [▬] button.
• The unit adopts the new value and returns to the operating mode.
• All LEDs left of the switch point light green.
• The switch point LED lights up red.

Restoring factory settings (reset)

• Press the [ + ] button for at least 15 seconds.
• All LEDs first light up orange, then flash orange.
• Release the button.
• All settings are reset to the factory setting:
• All LEDs go off for 2 seconds.

Lock/unlock

• The unit can be locked electronically to prevent unauthorized settings.
• Factory setting: not locked.
• Press both setting keys for 10 seconds.
• The display goes off.
• The unit is locked.
• For unlocking repeat the process.

Operation

• After power on, the unit is ready for operation.
• The device detects the flow and switches the output according to the setting.
• Output closed (LED = yellow) if flow ≥ switch point.
• Output open (LED = red), if volumetric flow quantity < switch point.
• In case of power failure or interruption of the operating voltage, all settings remain.

Troubleshooting

Maintenance, repair, and disposal

• Only the manufacturer is allowed to repair the unit.
• Ensure that the sensor tip is free from build-up:
• Check the sensor tip for build-up one month after set-up.
• Repeat check regularly. Determine check intervals based on the application.
• In case of soiling clean the sensor tip with a soft cloth. The stubborn build-up, such as lime, can be removed using a common vinegar cleaning agent.
• After use dispose of the device in an environmentally friendly way in accordance with the applicable national regulations.
