Control of MAKRO M5Ka metering pumps
Stroke length controller MAKRO M5Ka
Control drive consisting of an actuator with servomotor and integral microprocessor controller for stroke length adjustment via a standard signal. Actuating period approx. 100 sec for 100% stroke length, equipped with 2 limit switches for min./max. position, degree of protection: IP 54. Electrical connection 230 V (±10%), 50/60 Hz, approx. 40 W mechanical stroke length display fitted on the Makro/ 5 drive.
Special voltage/higher degrees of protection/explosion protection available on request.
Design with:
Standard current input 0/4-20 mA (corresponds to stroke length 0-100%); internal switch-over for manual/automatic operation, key switch for stroke adjustment in manual mode. Actual value output 0/4-20 mA for remote display.
Frequency converter for controlling speed in metal housing with IP 54 degree of protection
The frequency converter is accommodated in an IP 54 rated protective housing with integral control unit and main switch, suitable for motor capacity listed below.
Externally controllable with 0/4-20 mA or 0-10 V corresponding to 0-50 (60) Hz output frequency.
Integrated control unit with versatile functions, such as switching between external/internal control; frequency specified using arrow keys with internal control, multilingual fault message display etc.
With evaluation equipment for monitoring temperature of motor (thermistor protection).
Stroke sensor with Namur signal
Mounting on the crank drive mechanism of the Makro/ 5 gearbox. For precise measurement of each metering stroke, comprising electronic cams and inductive proximity switches, switching signal according to Namur. In combination with electronic pre-selection meters suitable for batch metering or proportional metering in conjunction with proportional control.
Retrospective fitting only possible in the factory.
Approved for explosion protection operation with degree of protection EEx ia II C T6.
