Commissioning
6.5 System setup with several analyzers in parallel
Example 2
Both analyzers without internal pump and without solenoid valve switching between sample
gas and zero gas for AUTOCAL
Via a digital output, the master controls a solenoid valve for switching between sample gas
and zero gas for the AUTOCAL.
The cyclic AUTOCAL of the master device triggers an AUTOCAL in parallel for the slave
device via its digital output SYNC and the digital input SYNC of the slave device.

Parameter assignments
Master:
● Enter the AUTOCAL cycle time, e.g.: 6 hours (see Calibration: AUTOCAL/drift values:
Cycle time (Page 123)).
● Assign the "Sync." function to a relay (see Configuration: Inputs/outputs/pump: Assign
relays (Page 138)).
● Assign the "Zero gas" function to a relay (see Configuration: Inputs/outputs/pump: Assign
relays (Page 138)).
● Assign the "Only CAL contact" function to the digital input SYNC (see Configuration:
Inputs/outputs/pump: Binary/sync inputs (Page 141)).
