  • Page 18: Function Groups

    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: 1) Offset adjustment (OFS) 2) Temperature Measurement / compensation settings (Set 3) Control relay 1 configuration (SP1) 4) Control relay 2 configuration (SP2) 5) Configuration (ConF) 6) Calibration (CAL pH)

    MEASUREMENT 5.1 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 pH or ORP value, while lower display shows either temperature value if controller is set for pH measurement or “OrP”...

  • Page 20: Calibration

    CALIBRATION Direct Calibration from Measurement mode is possible via the CAL key. Calibration procedure can also be accessed from Advanced Setup mode. 6.1 pH Calibration This unit features five preset buffer values (1.00, 4.00, 6.86 or 7.00, 9.00, 9.18 and 10.00) for quick, two-point auto calibration. When calibrating this instrument, standard pH buffer solutions must be used.
  • Page 21 3) Press ENTER key to start calibration at pH 7 (or pH 6.86). The electrode indicator and CAL indicator both flash. The controller automatically adjusts reading to match the buffer value. 4) The lower display will now show its next lower ‘pH’ buffer. Use Δ and ∇ keys to select second buffer from one of 5 remaining preset values.

  • Page 22: Orp - Mv Calibration

    ORP – mV Calibration This mode allows one-point calibration. 1) Enter Calibration mode. While in Measurement mode, push CAL key. Press ENTER key. The upper SETUP and lower display reads “CAL OrP”. HOLD Note: If upper and lower display read “CAL PH”, see section 7.4 for procedures on how to switch from pH to ORP mV readings.

  • Page 23: Advanced Set Up Mode

    ADVANCED SET UP MODE Electrode Offset (OFS) sub-function This option is available only in the pH mode. An allowance of ±120mV is allowed to correct for electrode deviations. This feature is useful for prolonged on-line applications. The controller will add or subtract the value from the measured pH and display the correct value.

  • Page 24: Setting Temperature (Set C) Sub-Function

    Note: Offset value is reset during full calibration. See section 6 for full calibration instructions. Note: The offset parameter is blanked out during ORP operation. Setting temperature (Set C) sub-function 7.2.1 Selecting automatic or manual temperature compensation 1) Enter Advanced Set-up mode by pressing ENTER key.

  • Page 26: Setting Manual Temperature Compensation

    7.2.3 Setting manual temperature compensation Note: This option is not available when the SETUP controller is set for ATC operation. HOLD For manual temperature compensation, two different temperatures: process and calibration, SETUP 25.0 input independently. This allows HOLD calibration at a temperature other than the process temperature.

  • Page 27: Control Relay A/Control Relay B (Sp1/Sp2) Sub-Function

    Control Relay A/Control Relay B (SP1/SP2) sub-function The SP1 option sets operating parameters for Relay A; the SP2 option sets operating parameters for relay B. Since these groups have the same set-up parameters, they are described together. 7.3.1 Entering Set point 1 (Set point 2) sub-function SETUP 1) Enter Advanced Set-up mode.

  • Page 28: Choosing High Or Low Set Points

    7.3.3 Choosing High or Low set points Select a “lo” to activate relay when the pH/ORP value undershoots the set point; select a “Hi” to activate relay when the value overshoots the set point. Using both SP1 and SP2, the following configuration for the set points can be selected: lo/lo, lo/hi, hi/lo, or hi/hi.

  • Page 29: Selecting A Hysteresis (Dead Band) Value

    7.3.4 Selecting a hysteresis (dead band) value Hysteresis prevents rapid contact switching if your value is fluctuating near set point. It does this by overshooting the set point value to a specified hysteresis value. You can set the hysteresis value from 0.1 to 1.0 pH, 10 to 100mV. Example: You have set your high set point at pH 9.0 and your hysteresis limit value at pH 0.5.

  • Page 30: Setting An On-Delay Time Lag

    7.3.5 Setting an on-delay time lag You can set as time delay for each relay, which stops the relay from switching on the moment the set point is exceeded. This controller lets you set a 0 to 2000 second time delay before the relay activates. SETUP HOLD 1) Follow directions in 7.3.1 to enter Control...

  • Page 31: Setting An Off-Delay Time Lag

    7.3.6 Setting an off-delay time lag You can set a time delay for each relay, which delays relay from switching off the moment the value reaches set point and hysteresis. Controller allows a timer delay from 0 to 2000 seconds time delay before deactivating. 1) Follow directions in 7.3.1 to enter Control Relay SETUP mode.

  • Page 32: Configuration (Conf) Sub-Function

  • Page 33: Selecting Ph Or Orp Mv Measurement

    7.4.2 Selecting pH or ORP mV measurement Besides selecting the controller to function as a pH or ORP (mV) controller, it also allows the selection of the type of input: symmetrical or asymmetrical. Symmetrical mode is used in conjunction with a potential matching pin – in an electrically noisy environment.

  • Page 34: Calibration (Cal) Sub-Function

    Calibration (CAL) sub-function The calibration procedure in Advanced Set-up mode is identical to the procedure in the Calibration mode. The only difference is that controller will revert back to Set-up mode (instead of Measurement mode) after calibration is completed. 7.5.1 Entering Calibration mode from Advanced Set-up mode 1) Enter Advanced Set-up mode.
