Inputs Signal Connections
The two inputs are assigned for external control commands. Inputs 6 and 7 require a DC voltage
between 5 and 24 Volts to activate. A 24 V supply is available from the main terminal strip pins
15 and 16 that can be used for activating the external control inputs.

Input 6 is assigned by default to RUN/STOP function with Close/Open of a dry contact.
Input 7 is left unassigned by default.
Dry contact = voltage free contact.
The functionality along with the state of the enabling signal is programmable by the user.
Communication Signal Connections
The analyzer has two communication connectors located at the right side in the upper cabinet.
