Page 3: Product Description
Product description Application The multifunction meter MFA 2001 is an electronic universal measuring device for measuring and monitoring all the important parameters in a three-phase supply network with a centre tap connection. The MFA 2001 is designed for fixed installation and registers voltages, currents, frequencies and phase shift. -
Page 4: Inputs, Outputs And Interfaces
Connections: All connections of the MFA 2001 are situated on the back of the casing. The block terminals are using screws to ensure safe and reliable connections with the network. For your attention ! ¦ Voltages above the permitted voltage range can destroy the device! ¦... -

Limit values/impulse output: Of each of the measured or calculated network parameters limit values can be monitored. These limit values can be assigned to both of the switched outputs. One or both of the limit value outputs can optionally be set as impulse output. Then a chain of impulses with the impulse ratio being proportional to the active energy is sent to the output. -
Page 6: Operation
Operation Controls The multifunction meter is operated by 4 control keys: When in display mode the 4 keys serve as hotkeys to activate pre-programmed display combinations. When in setup mode the keys are used to select the desired menus or program the device. -

An impulse valency (Wh / impulse) can be assigned to the impulse output. The system calculates an optimum time period to then collect the impulses within this time period and transmits them with an impulse length of 75 ms to the output.

For your attention ! ‹ For the switched output the latest set values for LIMIT 1 and LIMIT 2 are used. For better support we recommend to keep written protocol about settings and changes! ‹ It is possible to set either outputs LIMIT 1 or LIMIT 2 the impulse counter function. However, the impulse rate must be identical for both the outputs. -
