Procedures
Control Programs of Unical 9000(X)
Six programs and one service program can be called.
Four program flows are preset.
Three further programs can be entered by the user.
The programs are called via:
• Protos 3400(X)
• passive inputs Bin 1, Bin 2, Bin 3 (for DCS or switch, 24 V must be externally
supplied, see specifications)
Program Description Bin 3 Bin 2 Bin 1
1 Cleaning 0 0 1
2 Two-point calibration (Cal 2point) 0 1 0
3 One-point calibration (Cal 1point) 0 1 1
4 Park position (user-programmable) 1 0 0
5 User-programmable (User 1) 1 0 1
6 User-programmable (User 2) 1 1 0
7 Service program
The service program (7) stops all other running programs (1 - 6) immediately and
erases stored requests. For programs 1 - 6, the following applies:
When you start a new program, the remaining steps of a currently running pro-
gram are executed first. Further requests are stored and executed subsequently.
When you control the Unical via Protos 3400(X), you can block the Bin 1, Bin 2,
Bin 3 signal lines as well as M/S and A/M to prevent conflicts (Parameter setting /
Unical 9000 / Installation / Ext. control (DCS): Off).
Measurement Procedures
• Continuous measurement
After cleaning / calibration the pH sensor moves into the process for
measurement.
•
Short-time measurement
(interval measurement, sampling, sample
mode ...)
After cleaning / calibration the pH sensor remains in the calibration chamber
and only moves into the process for measurement upon request.
