45 MODEL 54e pH/ORP SECTION 6.0 THEOR Y OF OPERA TION SECTION 6.0 THEOR Y OF OPERA TION 6.1 THE pH SENSOR ASSEMBL Y The pH measurement is accomplished by means of a measuring electrode (usually made of glass) which develops a potential directly related to the hydrogen ion concentration (pH) of the solution in which the elec- trode is immersed.
46 MODEL 54e pH/ORP SECTION 6.0 THEOR Y OF OPERA TION A new glass electrode has an impedance of approxi- mately 200 megohms As it ages, this value typically increases over time because lithium ions (which carry current) in the glass are slowly depleted by the process.
MODEL 54e pH/ORP SECTION 6.0 THEOR Y OF OPERA TION 6.4 ALARM RELA YS An alarm is a relay that closes a set of contact point s (a switch) inside the controller . In doing so, the relay clos- es an electrical circuit and turns on a device wired to the contact s.
48 MODEL 54e pH/ORP SECTION 6.0 THEOR Y OF OPERA TION TPC offers precise control by forcing the pump to feed chemical for shorter periods of time as you approach the desired setpoint. If the process faces a large upset, TPC mode forces the pump to feed chemical for longer periods of time as the process deviates further from the setpoint.
MODEL 54e pH/ORP SECTION 6.0 THEOR Y OF OPERA TION 6.8 CONTROLLER MODE PRIORITY Y our Model 54e pH/ORP can function in dif ferent modes depending on both how it is configured, what process conditions exist, and actions an operator may have made.
50 MODEL 54e pH/ORP SECTION 6.0 THEOR Y OF OPERA TION 6.9 PID CONTROL (CODE -20) PID Control The Model 54e pH/ORP current output s can be pro- grammed for PID control. PID control is used with a control device which is capable of varying it s output from 0 to 100 percent in response to a changing sig- nal in milliamps.
MODEL 54e pH/ORP SECTION 6.0 THEOR Y OF OPERA TION 6.9 PID CONTROL (continued) Proportional Mode (Gain) The simplest control is proportional. Proportional may also be referred to as sensitivity or gain.
52 MODEL 54e pH/ORP SECTION 6.0 THEOR Y OF OPERA TION 6.9 PID CONTROL (continued) Process Reaction Curve Method A PID loop can be tuned using the Process Reaction Curve Method.
MODEL 54e pH/ORP SECTION 6.0 THEOR Y OF OPERA TION 6.9 PID CONTROL (continued) 5. The reaction of the system, when graphed, will resemble Figure 6-2, showing a change in the measured variable over the change in time. After a period of time (the process delay time), the meas- ured variable will start to increase (or decrease) rapidly .
