Page 9: Function Groups
Operating Instructions lpha-CON1000 Function Groups The main function and sub-function groups are organised in a matrix format for configuration and selection of parameters. The main function groups are: Temperature Coefficient settings ( tC tC Temperature Measurement / compensation settings ( S S E E t t Control relay 1 configuration ( Control relay 2 configuration (... -
Page 10: Control Concept
Control Concept The main function and sub-function groups are organised in a matrix format as shown below. These functions can be accessed via the front keypad for configuration and selection of parameters. The controller offers two levels of password protection: (1) for direct access to calibration function and (2) for setting or editing specific controller parameters or functions in the SETUP mode to suit individual requirements. -
Page 11: Measurement
Operating Instructions lpha-CON1000 MEASUREMENT Display in Measurement mode When the controller is initially powered on, it automatically enters into the Measurement mode after the large dual LCD displays all segments briefly. The upper display shows the measured Conductivity value, while the lower display shows the temperature value. - Page 12 NOTE: To view (not change) the SETUP parameters, push the ENTER key when the security code reads “000”. 68X216802...
- Page 13 Operating Instructions lpha-CON1000 5.2.1.1 Clearing the Calibration security code from the display The calibration security code automatically resets from “11” to “000” after you return to Measurement mode, so you do not need to clear the security code from the display. 5.2.2 How to enter and change parameters in Advanced Setup mode 1) Press the ENTER key once.

Page 14: Calibration Mode
Calibration Mode You can reach the Calibration mode directly from the Measurement mode by pressing the CAL key and entering the Calibration security code. You can also reach the Calibration mode from the Advanced Setup mode. Conductivity Calibration Calibration is always carried out in the specific range selected. The Conductivity Controller allows a one-point calibration. -
Page 15: Advanced Set-Up Mode
ADVANCED SET-UP MODE Temperature Coefficient sub-function This sub-function allows you to select the correct temperature coefficient for optimum operations. For applications in the pure water or ultr-pure water industries, simply select the “Pur” temperature coefficient option. For all other applications, select “Lin” temperature coefficient. The controller allows further input of temperature coefficient values, independently for the process and for the calibrating solutions. -
Page 16: Temperature Calibration (Atc Mode Only)
Temperature calibration (ATC mode only) Select “ATC on” as described above in Section 7.4.1. Press the ENTER key. The upper display indicates the current temperature offset. The current measured temperature is HOLD SETUP on on shown in the lower display. Compare the current measured temperature on the controller display to a thermometer known to be accurate. -
Page 17: Control Relay A/Control Relay B (Sp1/Sp2) Sub-Function
Operating Instructions lpha-CON1000 Control Relay A/Control Relay B (SP1/SP2) sub-function The SP1 option sets the operating parameters for Relay A; and SP2 for relay B. Since these groups have the same set-up parameters, they are described together. HOLD SETUP HOLD SETUP HOLD SETUP HOLD SETUP HOLD SETUP... - Page 18 Example: You have set your set point 1 (Lo) at 6.00 S and your hysteresis limit value is at 0.50 S. If your measured value undershoots the low set point of 6.00 S, the controller’s relay activates, which in turn activates an external device such as a pump or valve. The actions of the external device will cause the value to rise above 6.00 S.
