The input circuit at the analog input is layed out as a differential amplifier. If
the analog input is “open” there is already a voltage of 2 V. That means in
this case that the motor would be turning at a speed of about 2000 rpm. In
order to set 0 rpm the input must be connected over a low ohm resistor to
the analog ground (AGND) or connected to the AGND-voltage level.
27.
The micro annular gear pump may now be put into operation by increasing
the external voltage signal. A voltage signal of 0 V corresponds to 0 rpm
and 10 V to the maximal programmed speed (see chapter 1.7).
Remarks
:
−
You may adjust speed of the micro annular gear pump without the need to
connect it to the serial interface.
−
In case error occurs for example due to the motor overload - the green status
LED on the terminal Box S-G05 will turn red.
6.9.5
Startup with the RS-232 interface
28.
Connect the drive with the eight colored wires to the S-G05. The colors of
the corresponding wire connections are in the table 26.
29.
In order to prevent uncontrolled startup of the pump, bring the
potentiometer knob to the null position by turning it clockwise to the limit
stop.
30.
Put the DIP-switch to »Poti« position.
31.
Connect the RS-232 interface of the Terminal Box S-G05 with a free serial
interface of a PC. Use for that the delivered 9-pole null-modem cable.
32.
Now install the delivered software as described in the chapter 8.
33.
Connect the 24 VDC voltage supply to the terminal or to the DIN
connector.
34.
Provide for a steady liquid supply to the pump in order to avoid dry
operation of the device.
35.
The micro annular gear pump may now be put into operation with the
available software (operating mode RS-232 see chapter 8).
Remarks
:
−
In case error occurs for example due to the motor overload - the green error
status LED on the Terminal Box S-G05 will turn red.
