7.4 Operation
To operate a pump with the evaluation board, the following steps are necessary:
1) Connect the mp6/mp6-pp pump to the board according to the description in chapter 4.1.1. Due to
the orientation of the connector, the pump needs to be inserted with its metallic contacts upwards.
2) Choose the pump frequency setting with Jumper 1
3) Choose the pump amplitude setting with Jumper 2
4) Choose the power supply setting with Jumper 3
5) Connect the board with the voltage source
7.4.1 Pump frequency setting with jumper J1
Setting of Jumper J1
Internal frequency of the Frequency defined by capacitor Frequency defined by CLK input
mp6-OEM (100 Hz) C1 (predefined to 300 Hz)* on terminal CON1 – Pin 3
*50 Hz in versions delivered until July 2011
More information on the frequency setting with the CLK signal can be found in chapter 6.4.2. The capacitor
C1 can as well be changed by resoldering, see table 6.2.
7.4.2 Pump amplitude setting with jumper J2
Setting of Jumper J2
Maximum voltage Amplitude defined by Amplitude defined by AMP input
(235 V) variable resistor P1 on terminal CON1 – Pin 4
More information on the amplitude setting with the AMP signal can be found in chapter 6.4.2.
