Master:
S
Enter the AUTOCAL cycle time, e.g.: 6 hours (see Section 5.8.4).
S
Assign the function ”Sync.” to a relay (see Section 5.10.1.2).
S
Assign the function ”CAL/MEAS” to the digital input SYNC (see
Section 5.10.1.3).
Slave:
S
Set the AUTOCAL cycle time to ”0” to prevent a cyclic AUTOCAL
from being triggered (see Section 5.8.4).
S
Assign the function ”Sync.” to a relay (see Section 5.10.1.2).
S
Assign the function ”activate CAL relay” to the digital input SYNC
(see Section 5.10.1.3).
Both analyzers without internal pump and without internal
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.
