5. Provide for a sufficient liquid supply to the pump in order to avoid dry
operation of the device.
6. Connect the 24 VDC voltage supply to the screw clamp terminal or to the
DIN connector.
Make sure that the polarity of the supplied direct current is correct, otherwise
electronics may be damaged.
7. The micro annular gear pump may now be put into operation by increasing
the external current signal. 0 mA corresponds to 0 rpm and 20 mA to the
maximal programmed speed.
Remarks :
−
For operation with the signal 4…20 mA an offset of about 2.1 V should be
set by entering the command MAV2170. In order to set the nominal values
the micro annular gear pump must be put into operation via the RS-232
interface and start with the » Motion Manager « software. Save the
command in the EEPROM with the command EEPSAV (see chapter 10).
−
Speed of the micro annular gear pump may be set by sending an external
voltage signal without the need to connect the pump to the serial interface.
−
In case error occurs for example due to a motor overload - the green status
LED on the Terminal Box S-G05 will extinguish and a red one will light up.
