2 Safety instructions

- The unit described is a subcomponent for integration into a system.

• The system architect is responsible for the safety of the system.

• The system architect undertakes to perform a risk assessment and to create documentation in accordance with legal and normative requirements to be provided to the operator and user of the system. This documentation must contain all necessary information and safety instructions for the operator, the user and, if applicable, for any service personnel authorised by the architect of the system.

• Read this document before setting up the product and keep it during the entire service life.

• The product must be suitable for the corresponding applications and environmental conditions without any restrictions.
• Only use the product for its intended purpose (→ Intended use).
• 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.
  • Store the product in its original packaging.

3 Intended use

The device detects without contact if a set rotational speed is not reached and signals this by means of a switching signal.

4 Function

4.1 Switching function normally open

Transistor output	LED green	Description
Switched (conducting)	On	Rotational speed > SP + Hy and during the start-up delay
Not switched (non conducting)	Off	Rotational speed < SP

SP = switch point

HY = hysteresis

4.2 Damping

The yellow LED indicates the damping status of the sensor irrespective of either the switching function or the switching status of the transistor output.

Sensor state	LED yellow
Undamped	Off
Damped	On

4.3 Function diagram

1: Voltage supply
2: Start-up delay
3: Switching function normally open

SP: Switch point

Hy: Hysteresis

= transistor output switched (conducting)

The start-up delay suppresses an error message as long as the machine is in the process of starting and has not yet reached its minimum speed. After application of the voltage supply the start-up delay is effective only once.

If the plant is started and stopped frequently, linking the voltage supply of the drive and the speed monitor ensures that the start-up delay is effective each time the machine is switched on.

5 Installation

Fig. 1: Mounting principle

Fig. 2: Mounting specifications

▶ Fix the device using a mounting bracket and secure it by means of the nuts provided so that it cannot work loose.
▶ Adhere to the above mounting specifications to ensure a correct function.
▶ Install the unit flush.

6 Electrical connection

The unit must be connected by a qualified electrician.

▶ Observe the national and international regulations for the installation of electrical equipment.

▶ Disconnect power.
▶ Connect the unit as follows:

BK: black

BN: brown

BU: blue

7 Settings

Fig. 4: Operating and display elements

▶ Keep the minimum speed to be monitored in the plant on a constant level.
▶ Connect the device to the supply voltage.
▶ Wait until the start-up delay is over.
▶ Set the switch point depending on the status of the green LED.

7.1 Fine adjustment of switch point as normally open

When the green LED is off:

▶ Turn the potentiometer slowly anticlockwise (-) until the green LED is on.
▷ Setting is finished.

When the green LED is on:

▶ Turn the potentiometer clockwise (+) until the green LED is off.
▶ Turn the potentiometer slowly anticlockwise (-) until the green LED is on.
▷ Setting is finished.

1: Multi-turn potentiometer for switch point setting (without end stop)

2: LEDs:

• Green LED for switching status indication → Function
• Yellow LED for damping indication (input signal) → Damping

8 Operation

The operation is maintenance-free.

Ensure the following for a correct function:

▶ Keep the sensing face and the clear space free of metal deposits and foreign bodies.
▶ Do not operate devices with high field intensity (e.g. mobile phones) at close range to the speed monitor.

9 Maintenance, repair and disposal

The operation of the unit is maintenance-free.

Only the manufacturer is allowed to repair the unit.

▶ After use dispose of the device in an environmentally friendly way in accordance with the applicable national regulations.
