1 INTRODUCTION

1.1 Description of Unit

Thank you for purchasing ¼ DIN 800 series pH/ORP process controllers. This unit is used for measuring either pH or ORP parameter one at a time, and the operational mode is switchable from the menu. You can use this unit to measure pH or ORP with limit control. This controller has many userfriendly and safety features which include:

• Menu-driven program that simplifies set-up

• Built-in non-volatile memory backup to ensure that calibration and

other information are not erased if power supply fails

• Push-button two-point calibration and electrode offset adjustment from the keypad

• Automatic temperature compensation (ATC)

• Manual temperature compensation setting without the ATC probe, with

independent setting for calibration and process temperature

• 0 to 2000 second time delay adjustment on all relays – minimise false alarms

• Separately adjustable high and low set point hysteresis (dead bands) prevent chattering of relays around the set points

• Asymmetrical/symmetrical input for pH/ORP operation

• Large dual display LCD for easy reading with clear multiple

annunciators, alarm status, operational and error messages

• Two switching contacts as set-point triggering relays

• Hold function freezes output current (4/20mA) and control relays

• LED indicators signal control activities to monitor controller status from a

distance

Page 9

• Protection against electromagnetic interference – Input and output

are free from external inference

1.2 Applications

Use this controller in panel mounted enclosures for applications such as water treatment and monitoring, galvanic-decontamination, chemical processing food processing, clean or waste water control and neutralisation

process

5 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” if it is set for ORP measurement.

Annunciators at right side of display indicate whether controller is set for pH or mV measurement.

Similarly annunciators or icons at top or left side of display shows current status of controller, e.g. “MEAS”, “SETUP”, “CAL”, “READY”, etc. In addition, error messages also guide user in time of any faulty conditions as indicated by “ERR” or icons flashing.

5.1.1 Check electrode performance

To read current electrode slope and offset values:

1) Press CAL key followed by ENTER key. The upper display shows electrode slope. The lower display reading shows the pH reading at 0 mV.

2) Press Δ and ∇ key s to return to Measurement mode.

Page 20

6 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.

1) Enter Calibration mode. While in Measurement mode, push CAL key. Upper and lower display reads “CAL” & “pH”. Push ENTER or CAL key again. The controller displays electrode status based on previous calibration. Electrode slope and offset information is displayed. NOTE: If display reads “CAL OrP”, see section 7.4 for procedures on how to switch from ORP to pH readings.

2) Press ENTER key again to begin calibration. The “CAL” indicator appears at top of display and

first compulsory calibration value, pH 7.00 (or

6.86). Immerse clean electrode in buffer solution. In ATC, temperature probe must also be immersed in buffer solution. Likewise for symmetrical mode, immerse potential matching pin in buffer.

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. Remove electrode from first buffer, wash and then immerse into second buffer. Once upper display stabilises press ENTER key, electrode and CAL indicator will flash. The controller adjusts reading to the buffer.

5) After calibrating to a second buffer value, controller automatically displays electrode slope and offset. The zero point and slope are re-determined after each calibration.

6) Press ENTER key. If calibration mode was accessed using CAL key, controller will return to Measurement mode. If calibration mode was accessed from Advanced Set-up mode, controller will return to sub-function menu. Note: If there is a calibration error, controller displays “ERR”. If this happens, push both

Δ and ∇ keys (escape) to restart calibration beginning from step 1.

Note: When calibrating with manual temperature compensation, controller

automatically changes from preset process temperature to calibration temperature. After leaving Calibration mode, controller switches back to process temperature (for setting calibration temperature and process temperature, see section 7.2.3).

Page 22

6.2 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 and lower display reads “CAL OrP”. 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.

2) Place sensor in ORP solution.

3) Press ENTER key to begin calibration. “CAL” indicator appears on display. Upper display shows current mV output of electrode without any offset adjustment.

7.1 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. Should the offset value be too high, consider performing maintenance on the electrode followed by calibration. If the calibration is unsuccessful, please replace the electrode.

controller to activate the respective relays.

1) Follow directions in 7.3.1 to enter Control Relay mode. If you are in this mode, skip to step 2.

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.

1) Follow directions in 7.3.1 to enter Control Relay mode.

2) Press ENTER key until upper display shows Lo or Hi and lower display shows SP1 (SP2).

4) Press ENTER key to confirm.

5) Proceed to 7.3.4 step 3, or return Measurement mode by pressing Δ and ∇ keys simultaneously (escape).

Page 29

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. If your measured value overshoots high set point pH 9.0, the controller’s relay activates, which in turn activates external devices such as a pump or valve. The actions of the external device will cause the solution’s pH to drop. When the pH drops to 8.5 pH, the relay and hence the pump will switch off.

1) Follow directions in 7.3.1 to enter Control Relay mode.

2) Press ENTER key. Scroll with Δ or ∇ keys

11 APPENDICES

11.1 Appendix 1

Before opening the unit, ENSURE that the power cable is physically separated from the power supply.

Jumper Positions - Internal to the controller

JP 1 Selects the input voltage 220 VAC. JP 2 Selects the input voltage 110 VAC. JP 3 Solder bridge selects between Pt100 and Pt1000.

Fuse Note that there is a fuse (slow-blow 100mA) internal to the

controller. Replace fuse with the recommended type only.

Simple Explanation on the Function of Hysteresis

The controller relay activates when the set-point is reached. In the reverse direction, it does not de-activate when the value reaches the set-point. Instead, it continues to be active till the value reaches the amount set by the Hysteresis band.
