Parameter assignments
The two analyzers must be parameterized as follows:
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 Calibration: AUTOCAL/drift values: Cycle time
(Page 123)).
● Assign the "Only CAL contact" function to the digital input SYNC (see Configuration:
Inputs/outputs/pump: Binary/sync inputs (Page 141)).
Slave:
● Set the AUTOCAL cycle time to "0" to prevent a cyclic AUTOCAL from being triggered
(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 "AUTOCAL" function to the digital input SYNC (see Configuration:
Inputs/outputs/pump: Binary/sync inputs (Page 141)).
