The servicing was done by Pfeiffer Vacuum. According to the mechanic, one of the control commands was changed during servicing so that the pump is not starting automatically when power is applied. However, it looks like the pumping station expects the pump to start automatically. </span><br ng-non-bindable="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: monospace;"><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: monospace; font-size: medium;">We assume that the mechanic reset all control commands to factory default during the servicing. So we wanted to ask, if anybody knows the important control commands Gatan uses for the HIPACE pump. For example, it would be very important for us to know at which rotation speed the pump is working in the pumping station.</span><br ng-non-bindable="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: monospace;"><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: monospace; font-size: medium;">Thanks in advance for any response.</span><br ng-non-bindable="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: monospace;"><br ng-non-bindable="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: monospace;"><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: monospace; font-size: medium;">Cheers</span><br ng-non-bindable="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: monospace;"><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: monospace; font-size: medium;">Eric</span><div><font color="#000000" face="monospace" size="3"><span style="caret-color: rgb(0, 0, 0);"><br></span></font></div><div><font color="#000000" face="monospace" size="3">————————————————————————</font></div><div><font color="#000000" face="monospace" size="3"><span style="caret-color: rgb(0, 0, 0);">Eric Mark</span></font></div><div><font color="#000000" face="monospace" size="3"><span style="caret-color: rgb(0, 0, 0);">Universität Potsdam</span></font></div><div><font color="#000000" face="monospace" size="3"><span style="caret-color: rgb(0, 0, 0);">AG Biochemie</span></font></div><div><font color="#000000" face="monospace" size="3"><span style="caret-color: rgb(0, 0, 0);">Karl-Liebknecht-Str. 24-25</span></font></div><div><font color="#000000" face="monospace" size="3"><span style="caret-color: rgb(0, 0, 0);">14476 Potsdam-Golm</span></font></div><div><font color="#000000" face="monospace" size="3"><span style="caret-color: rgb(0, 0, 0);"><br></span></font></div><div><font color="#000000" face="monospace" size="3">E-Mail: Eric.mark@uni-potsdam.de</font></div><div><font color="#000000" face="monospace" size="3">Telefon: 0331 977 5122</font></div><div><font color="#000000" face="monospace" size="3">————————————————————————</font></div></body></html>
