USER MANUAL DC0103 IFM

auf Leiterplatte, Umgebungstemperatur -20°C ... +60°CFunction 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.

Intelligent switch point setting while machine is in operation (“teach-in”). Controls and indicators S1, S2, S3: programming buttons H6: red LED flashes when D min is programmed H7: red LED flashes when D max is programmed H8: green LED , supply voltage H9: green LED is lit when the relay is energised H10: yellow LED, indication of the input pulses DmaxDminDmaxDmin

X4X3X2X1 123Mounting Mount the unit with screws on a mounting base. Mounting of the pulse pick-up For optimum functioning the following mounting dimensions should be adhered to: PG 11

at least diameter of thespeed monitorat least 2 x A1/2 x S

SealElectrical connection Disconnect power. Open transparent front panel and connect the unit as follows: The unit is equipped with integrated C-Mos components. They can be destroyed by electrostatic discharge (ESD). Thus no com- ponents except for push-buttons and connection terminals may be touched.

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.

Set the maximum rotational speed of the machine and keep it constant LED H10 flashes in time to the input pulses Press the push- buttons and hold them until LED H7 flashes LED H7 is constantly lit and flashes when D max is stored Set the minimum rotational speed of the machine and keep it constant LED H10 flashes in time to the input pulses Press the push- buttons and hold them until LED H6 flashes LED H6 is constantly lit and flashes when D min is stored

4Accessories Rotational speed display for service and operation. You can connect an external display on the terminal block X4 to display the actual rotational speed.
