Requirement:
To meet the regulatory requirements of immunity from
external electrical disturbances, install connection covers over the signal
connectors.
Mass spectrometer signal connections:
Signal connections Description
Analog Out Used for analog chart output functionality. The
output voltage range is 0 to 2 V. The resolution of
the voltage output is 12 bits.
Gas Fail Interlock Out Used to stop the solvent flow if the nitrogen gas
supply fails. Maximum 30 V 0.5 A, 10 W.
Event Out 1, Event
Out 2
Allows the mass spectrometer to trigger an external
event.
Event In 1, Event In 2 Allows an external device to start data acquisition.
Maximum 30 V.
CE interlock Out Interfaces with a capillary electrophoresis power
supply so that the instrument is safely interlocked
against high voltages.
