The manual functions in two ways: firstly as a step by step guide to help the user operate the instrument. This instruction manual is written to cover as many anticipated applications of the lpha-CON1000 Conductivity controller/transmitter. If you have doubts in the use of the instrument, please do not hesitate to contact the nearest Eutech Instruments' Authorised Distributor. [. . . ] This option allows you to input the Process Temperature coefficient, from 0 to 10%. Use the or keys to enter the required temperature coefficient value. Next, enter the calibration solution temperature coefficient value, from 0 to 10%. 5) Press the or keys to input the desired calibration solution temperature coefficient. 6) Press the ENTER key to accept the value. 2. 10 C. tC % ATC 7) Continue with additional Advance setup procedures or return to Measurement mode by pressing the and keys (escape) simultaneously. 68X216802 7. 2 Temperature calibration (ATC mode only) 1) Select "ATC on" as described above in Section 7. 4. 1. 3) Compare the current measured temperature on the controller display to a thermometer known to be accurate. 4) Press the or keys to scroll the lower display to match the correct value. 6) Continue with additional Advanced Set-up procedures, or return to the Measurement mode by pressing the and keys (escape) simultaneously. HOLD SETUP on Atc HOLD SETUP 0. 0 25. 0 o C ATC 7. 2. 1 Setting manual temperature compensation Note: This parameter is blanked out when the controller is set for HOLD SETUP ATC operation. For manual temperature compensation, you can set two different temperatures: process and calibration. This allows calibration at a Atc temperature other than your process temperature. Example: setting a calibration temperature of 25 oC lets you calibrate using standard buffer solutions at 25 oC, even if your process temperature is a HOLD SETUP different temperature. 1) Select "ATC oFF" as described above in section 7. 4. 1 2) Press the ENTER key. The upper display shows the current P. C process temperature and the lower display shows "P. oC" to indicate process temperature. oFF 25. 0 HOLD SETUP 25. 0 C. C 5) 6) 7) 3) Press the or keys to adjust the process temperature value. The upper display shows the current calibration temperature and the lower display shows "C. oC" to indicate calibration temperature. Press the or keys to adjust the calibration temperature value. Continue with additional Advanced Set-up procedures, or return to Measurement mode by pressing the and keys (escape) simultaneously. 68X216802 Operating Instructions lpha-CON1000 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.

Push the ENTER key and HOLD SETUP scroll to Advanced Set-up security code "22". Push the ENTER key again. SP 1 2) Press the or keys to scroll until the upper display shows SP1 (SP2). HOLD SETUP 100 SP 1 HOLD SETUP µS Lo SP 1 7. 3. 2 Selecting the set point values This lets you choose the value that will cause your controller to activate (Default: SP1 = 6. 20mg/l; SP2 = 4. 00mg/l). The upper display shows the current set point value and the lower display shows SP1 (SP2). 3) Press the or keys to select your value for Set point 1 (Set point 2). 5) Proceed to 7. 5. 3, or return to Measurement mode by pressing the and keys simultaneously (escape). 7. 3. 3 Choosing High or Low set points Select a low set point to activate controller when the dissolved oxygen 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). [. . . ] The relays are now back under automatic control. 68X216802 24 Operating Instructions lpha-CON1000 9 Technical Specifications Conductivity Range 0. 000 to 1. 999 µS/cm 0. 00 to 19. 99 µS/cm 0. 0 to 199. 9 µS/cm 0 to 1999 µS/cm 0 to 5000 µS/cm 0. 00 to 19. 99 mS/cm 0. 0 to 199. 9 mS/cm Resolution 0. 001 µS/cm 0. 01 µS/cm 0. 1 µS/cm 1 µS/cm 5 µS/cm 0. 01 mS/cm 0. 1 mS/cm Default Cell Constant, K 0. 01 0. 01 0. 1 1. 0 1. 0 1. 0 10. 0 Optional Cell, K 0. 1 1. 0 1. 0 Temperature Resolution Relative Accuracy Sensor Temperature Compensation Set-point and Controller Functions Controller characteristics Pickup / Dropout delay Switching Condutivity hysteresis Contact outputs, controller Switching voltage Switching current Switching power Alarm Functions Function (switchable) Pickup delay Switching voltage Switching current Switching power Electrical Data and Connections Power Requirements Frequency Signal Output Signal Output Load Connection terminal Mains fuse / fine wire fuse EMC Specifications Emissions Susceptibility Environmental Conditions Ambient temp. operating range Relative humidity Mechanical Specifications Dimensions (control panel housing - L x H x W) Weights (control panel housing) Material Insulation (Front / Housing) 0-50 oC (Display: -9. 9 to 125 oC) 0. 1 oC ± 0. 5 oC Pt 1000/Pt 100 Auto / manual (reference at 25. 0 oC) Limit controller 0 to 1999 sec. 600 VA 110 / 220 VAC (jumper selectable) 48 to 62 Hz 0/4 to 20 mA, galvanically isolated max. 600 Terminal blocks 5-pole / 17-pole, removable slow-blow 250 V / 100 mA According to EN 50081-1 According to EN 50082-1 0 to 50 oC 10 to 95%, non-condensing 175 x 96 x 96 mm max.
