Frequently Asked Questions - DC0103 IFM

How to set the maximum switching point (Dmax)?

Reach the maximum rotation speed of the machine and keep it constant. LED H10 flashes. Press and hold pushbutton S1 until LED H7 flashes. The value is then saved.

How to set the minimum switching point (Dmin)?

Reach the minimum rotation speed of the machine and keep it constant. LED H10 flashes. Press and hold pushbutton S2 until LED H6 flashes. Dmax must always be greater than Dmin.

What do the different LEDs mean?

H8 (green): supply voltage present. H10 (yellow): indicates input pulses. H9 (green): lit when the relay is energized. H7 (red): flashes during programming of Dmax. H6 (red): flashes during programming of Dmin.

How to connect a pulse sensor?

Turn off the system. Open the transparent front. Connect the PNP sensor to terminal block X1: + wire to terminal 1, signal wire to terminal 2, - wire to terminal 3. Power supply 12V or 24V DC is connected to X2 (+ and -). The relay is connected to X3.

What is the required supply voltage?

The device operates on either 12V DC or 24V DC. The voltage must be stabilized and connected to terminals X2 (12V/0V or 24V/0V).

Can I use an external display?

Yes, you can connect an external display (ref. E80103) to terminal block X4 (terminals 1, 2, 3) to dynamically display the rotation speed.

How to perform self-teaching?

Self-teaching is done by successively setting Dmax and Dmin as described in the previous questions. The machine must be running at the desired speed during programming.

What precautions should be taken against electrostatic discharge?

The device contains sensitive CMOS components. Do not touch any internal components except pushbuttons and connection terminals. Work in an ESD-protected environment.

What is the operating temperature range?

The device operates from -20°C to +60°C. Make sure not to exceed these limits.

How to mount the device?

Mount the device with screws on a flat surface. Use the provided sealing gasket to ensure IP65. The mounting dimensions are indicated in the manual: center distance 130 mm, diameter 94 mm.

Function and features

The DC0103 monitors rotational speeds (mainly with regard to under-speed).

It takes pulses from external pulse pick-ups and switches the output relay depending on the set switch point max ( D_max ) and switch point min ( D_min ).

The output relay

• is energised when the maximum rotational speed is reached
• is de-energised when the speed is below the min. rotational speed.

DmaxDmin DmaxDmin

- Setting range: 30 ... 25 000 pulses /min.

- Intelligent switch point setting while machine is in operation ("teach-in").

Mounting of the pulse pick-up

For optimum functioning the following mounting dimensions should be adhered to:

E B C A D

A } at least diameter of the speed monitor B C
D at least 2 x A
E 1/2 × S_n

Electrical connection

Disconnect power.

Open transparent front panel and connect the unit as follows:

X3X2X1 X3X2X1 1 2 3 1 2 3 1 2 3 + - + 12V 0V 24V UB ⊕ ∥ ⊖ sensor 12V PNP relay X4 1 2 3 ⊕ ∥ ⊖ display

The unit is equipped with integrated C-Mos components. They can be destroyed by electrostatic discharge (ESD). Thus no components except for push-buttons and connection terminals may be touched.

Setting

1	Set the maximum rotational speed of the machine and keep it constant			LED H10 flashes in time to the input pulses
2		Press the push-buttons and hold them until LED H7 flashes
3	Set the minimum rotational speed of the machine and keep it constant			LED H10 flashes in time to the input pulses
4		Press the push-buttons and hold them until LED H6 flashes		H6●LED H6 is constantly lit and flashes when Dminis stored

Press the push-buttons and hold them until LED H6 flashes

H6●LED H6 is constantly lit and flashes when Dmin is stored

	LED H6 is constantly lit and flashes when Dmin is stored

D_max must always be greater than D_min !

Operation

Check the safe functioning of the unit.

If operation is correct no special measures need to be taken nor any measures for maintenance and upkeep.

For operation and maintenance of the pulse pick-ups the manufacturer's instructions must be observed.

Accessories

Rotational speed display for service and operation.

You can connect an external display on the terminal block X4 to display the actual rotational speed.
