MC-Series: Line break recognition

12


•Automatic line break recognition in modulated mode (2...10V or 4... 20mA):

When Y-Signal drops below 1V or 2mA, the actuator moves to the limit position set by

coding switch S6•Control LED on board

MC-Series: Error detection

13


•In case the valve becomes mechanically blocked, e.g. by a particle, the actuator returns briefly and tries up to seven times again to reach the required position. If the

particle is still there then, the actuator stops. A control LED blinks.

MC-Series: Repeat back signal by manual actuation

HORA MC Series: Advantages

16


Flexible:

1 .In series suitable for 3-point signal as well as for continuous control signal.

2 .Possibility to change the speed on site by the simple use of DIP-switches.

3 .DC is possible as well as AC in the 24V version.

Note: The use of smoothed DC is possible with the MC103, MC253 and MC503. For the MC1003, the thrust is reduce by 20%, for the MC1503 by 10% and for the MC163

by 20%. For the MC403, the actuating speed has to be reduced. The use of the MC103-SE with 24V smoothed DC is not recommended.

The use of smoothed DC always has to be stated in the order .


HORA MC Series: Advantages

Flexible:

4 .Prepared for looping-in of an external binary signal, e.g. a frost

protection sensor

5 .Prepared for additional options (position switches…)
