Cell Diagnostics; Relay Test; Current Output Test - ABB Aztec 600 User Manual

Aztec 600 aluminium, ammonia, color, iron, manganese, phosphate
Single- and multi-stream colorimetric analyzers

10.2 Cell Diagnostics

Cell Diagnostics enables the user to control the operation of the analyzer manually – bringing in reagents and sample etc. It also
displays the detector output in real time giving an insight into how the analyzer is performing.
Note.
If this procedure is selected when the analyzer is in
operation, a warning is displayed:

10.3 Relay Test

All of the alarm relays can be set individually or reset to check their operation.
Note. This procedure affects the analyzer relay functions and the analyzer

10.4 Current Output Test

Within the Current Output Test Screen the user is able to check the analyzer current outputs manually.
A calibrated ammeter is required for this test. Put the leads from the ammeter onto the two current output terminals on the I/O board
– see Section 4.6.3, page 18.
Check that the value shown on the analyzer LCD is the same value shown on the ammeter.
Use the and keys to increase/decrease the milliamp value.
If the ammeter and analyzer do not agree it may be necessary to recalibrate the current outputs – see Section 6.5.2, page 36.
Note. This procedure affects the current outputs of the analyzer and the analyzer
