Master:
• Enter the AUTOCAL cycle time, e.g.: 6 hours (see Calibration: AUTOCAL/drift values: Cycle
time (Page 126)).
• Assign the "Sync." function to a relay (see Calibration: AUTOCAL/drift values: Cycle time
(Page 126)).
• Assign the "Only CAL contact" function to the digital input SYNC (see Con󹪝guration: Inputs/
outputs/pump: Binary/sync inputs (Page 143)).
Slave:
• Set the AUTOCAL cycle time to "0" to prevent a cyclic AUTOCAL from being triggered
(see Calibration: AUTOCAL/drift values: Cycle time (Page 126)).
• Assign the "Sync." function to a relay (see Con󹪝guration: Inputs/outputs/pump: Assign relays
(Page 140)).
• Assign the "AUTOCAL" function to the digital input SYNC (see Con󹪝guration: Inputs/outputs/
pump: Binary/sync inputs (Page 143)).
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.
