pH Meter
A Signet pH meter has been mounted on the panel
for displaying the current pH and temperature of
the tank bath. The program pH meter is tied to the
program with user defined pH limits. If a reading
falls out of limit, the system will stop running and
the HMI interface will read pH error. At this point
the operator will need to manually add solution to
the tank to adjust the pH, or change the limits in
the system. Pressing the start button will resume
the program.
Programmable Controller
An IDEC programmable controller is used to control the process. The unit has a
flash memory backup without a battery. The controller has indicator lights for
inputs and outputs which are lit during process. The system is also equipped with
a Beijer, EXTER model touchscreen interface. The interface allows for data
collection of the passivation process. The following data is collected and stored on
the interface:
Clean time
