This refers to a condition in which nothing happens when the MSD is switched on. The foreline pump does not start. The cooling fan for the high vacuum pump does not turn on. The status LED on the front of the MSD does not light.
Make sure it is connected to an appropriate electrical outlet
Make sure power is present and it is the correct voltage for your MSD.
WARNING! Only a trained electrician should check the electrical outlet.
Check and, if necessary, replace the primary fuses. See the MSD maintenance documentation for instructions for replacing the primary fuses. Failed primary fuses are generally a symptom of a more serious problem. If the primary fuses fail repeatedly, contact your Agilent Technologies service representative.
WARNING! The primary fuses carry hazardous voltages. Vent the MSD and disconnect the MSD power cord from the electrical outlet before checking or replacing the primary fuses.
Contact your Agilent Technologies service representative.
