Maintenance and Servicing
System Alarms and Errors
Action
Check float operation.
Check float wiring.
Check float installation.
Using Thermo Scientific TII menu
screens, set reservoir type to "Alter-
nate" (in "System Options").
Check float cable connection.
Check float operation.
Check float wiring.
Check float installation.
Using Thermo Scientific TII menu
screens, set reservoir type to
"Thermo Scientific TII" (in "System
Options"). Ensure interface connec-
tor is securely connected to the
Thermo Scientific TII and the
Thermo Scientific TII storage reser-
voir.
Replace control board (PC1403X3).
Calibrate meter using NIST mod-
ule.
Replace control board (PC1403X3).
Follow the enclosed calibration
instructions.
Check resistivity cell lead connec-
tion on board.
Replace resistivity cell (E1403X6).
Check the temperature of the stor-
age reservoir water.
Replace control board (PC1403X3).
Ensure that reading on tag agrees
with reading in software.
Install a new cartridge pack
(D502137) and reset timer.
Check that cartridge pack is
installed.
Replace resistivity cell (E1403X6).
Replace control board (PC1403X3).
Ensure that reading on tag agrees
with reading in software.
