Siemens ULTRAMAT 23 Series - System Setup with Several Analyzers in Parallel

The calibration with calibration gas should be repeated every six to twelve months depending
on the ambient conditions.
6.4 System setup with several analyzers in parallel
Example 1
Both analyzers with internal pump and solenoid valve switching between sample gas and
zero gas for 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.
The simultaneous connection between the digital output SYNC of the slave device and the
digital input SYNC of the master device guarantees that zero gas is always passed simultaneously
through both analyzers.
