User manual EUTECH INSTRUMENTS ALPHA CON 1000 CONDUCTIVITY CONTROLLERTRANSMITTER (REVISION 3)

[. . . ] Instruction Manual lpha-CON 1000 Conductivity Controller/Transmitter Technology Made Easy . . . 68X216802 rev 3, 11/04 This manual serves to explain the use of the lpha-CON1000 series Conductivity controller/transmitter. The manual functions in two ways: firstly as a step-by-step guide to help the user operate the instrument. Secondly, it serves as a handy reference guide. This instruction manual is written to cover as many anticipated applications of the lpha-CON1000 Conductivity controller/transmitter. [. . . ] 6) After you set the process temperature value, press the ENTER key. The upper display shows the current calibration temperature and the lower display shows "C. ºC" to indicate calibration temperature. 7) Press the or keys to adjust the calibration temperature value. You can adjust the value from -9. 9 to 125 ºC. FF 25. 0 25. 0 13 Operating Instructions lpha-CON1000 8) 9) Press ENTER key to confirm your selection. Continue with additional Additional Set-up procedures, or return to Measurement mode by pressing the and keys (escape) simultaneously). 7. 3 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.

Refer to Section 7. 5. 1 for Selecting the Measuring Range sub-function. Push the ENTER key and (use or keys to) scroll to Advanced Set-up security code "22". Push the HOLD SETUP 2) ENTER key again. Press the or keys to scroll until the upper display shows SP1 (or SP2). HOLD Sp1 SETUP 7. 3. 2 Selecting the set point values This lets you choose the value that will cause your controller to activate (Default: SP1 = 100 µS; SP2 = 1900 µS). 1) Press the ENTER key until upper display shows the current set point value and the lower display shows SP1 (or SP2). 2) Press the or keys to select your value for Set point 1 (or Set point 2). Your controller will activate at the value you select. 3) Press the ENTER key to confirm your selection. 4) Proceed to 7. 3. 3, or return to Measurement mode by pressing the and keys simultaneously (escape). 100 6 µS Sp1 HOLD SETUP L 6 Sp1 14 Operating Instructions lpha-CON1000 7. 3. 3 Choosing High or Low set points Select a low set point to activate controller when the conductivity value undershoots the low set point; select a high set point to activate controller when the value overshoots the high set point. Using both SP1 and SP2, you can select lo/lo, lo/hi, hi/lo, or hi/hi set points (Default: SP1 = Lo; SP2 = Lo). 1) Follow directions in 7. 3. 1 to enter Control Relay mode. Scroll with the or keys until the upper display shows Lo or Hi (for low or high set point) and the lower display shows SP1 (or SP2). 3) Press the or keys to select low (lo) or high (hi) set point for SP1 (or SP2). 4) Press the ENTER key to confirm your selection. 5) Proceed to 7. 3. 4, or return Measurement mode by pressing the and keys simultaneously (escape). 7. 3. 4 Selecting a hysteresis (dead band) value Hysteresis prevents rapid contact switching if your value is fluctuating near the set point.
