7. Setup

Setup should be done before using this instrument according to the user’s conditions:

Setting the ORP input function (input high limit, low limit), EVT1, EVT2, EVT3 (EVT3 option) and EVT4 (EVT3 option) types, Communication (C5 option), Transmission output, Indication settings (Backlight selection, ORP color, etc.) and Cleansing action.

Setup can be conducted in the ORP Input group, EVT1, EVT2, EVT3, EVT4 Action groups and Special Function group.

If user’s specification is the same as the factory default of the AER-101-ORP, or if setup has already been completed, it is not necessary to set up the instrument. Proceed to Section “8. Calibration (p.52)”.

7.1 Turn the Power Supply to the AER-101-ORP ON.

For approx. 4 seconds after the power is switched ON, the following characters are indicated on the ORP Display and Setting Display.

ORP Display Setting Display

Unlit

During this time, all outputs are in OFF status, and action indicators go off. After that, measurement starts, indicating the item selected in [Backlight selection (p.49), ORP color (p.49), Bar graph indication (p.50), Setting Display indication (p.50)] in the Special Function group. This status is called ORP Display mode or Cleansing Output mode.

7.2 ORP Input Group

To enter the ORP Input group, follow the procedure below.

Press the key in ORP Display mode or Cleansing Output mode.

Press the key. The unit proceeds to the ORP Input group, and “Moving average data amount” will appear.

Character Setting Item, Function, Setting Range Factory Default

Moving average data amount 3

• Sets the number of ORP inputs for calculating the moving average.

• Setting range: 1 to 20

Input high limit 2000 mV

• Sets the high limit value for ORP input indication.

• Setting range: Input low limit to 2000 mV

Input low limit -2000 mV

• Sets the low limit value for ORP input indication.

• Setting range: -2000 mV to Input high limit

ORP input filter time constant 0.0 sec.

• Sets ORP input filter time constant. Even when ORP value before filter process changes as shown in (Fig. 7.2-1), if the filter time constant “T” is set, the ORP value changes as shown in (Fig. 7.2-2) so that ORP value after finishing filter process can reach 63% (of the desired ORP value) after T seconds have passed. If the filter time constant is set too large, it affects EVT action due to the delay of response. (e.g.) If the LSD (least significant digit) of the ORP value prior to

filter process is fluctuating, it can be suppressed by using the filter time constant.

9.6 ORP Input Error Alarm

ORP input error alarm is used for detecting actuator trouble. Even if ORP input error alarm time has elapsed, and if ORP input does not become higher than ORP input error alarm span, the unit assumes that actuator trouble has occurred, and writes Status flag 2. In Serial communication, status can be read by reading Status flag 2 (EVT1, EVT2, EVT3, EVT4 output flags). If (ORP input error alarm output) is selected in [EVT1 type (p.23)], EVT1 output will be turned ON. The same applies to EVT2, EVT3 and EVT4.

ORP input error alarm is disabled in the following cases:

• During Adjustment mode or Span sensitivity correction mode

• When (Cleansing output) is selected in any of EVT1 to EVT4 type (p. 23, 29, 35, 41), and cleansing is performing using the ‘Cleansing time’ and ‘Restore time after cleansing’ settings.

• When ORP input error alarm time is set to 0 seconds (or minutes) or ORP input error alarm span is set to 0 mV.

9.7 Cycle Automatic Variable Function

If deviation between EVT value and measured value enters EVT cycle variable range, the proportional cycle will be automatically extended in accordance with the deviation. Proportional action OFF time will be extended, and ON / OFF ratio will be adjusted. However, if EVT cycle extended time is set to 0 (zero), this function will be disabled.

Adjustment Mode

For successful measurement of ORP, ORP value in the sensor location, electrode performance and standard solution accuracy respectively play an important role for obtaining reliable data. By setting the adjustment value, calibrates ORP value indicated on the AER-101-ORP to read 260 mV (at 20 ) when immersing the ORP Combined Electrode Sensor in the standard solution (Quinhydrone potential difference 260

mV). Span Sensitivity Correction Mode

Cleansing Output Cleansing Output Mode

If (Cleansing output) is selected in any of [EVT1 to EVT4 type (pp. 23, 29, 35, 41)], the unit will enter Cleansing Output mode.

While cleansing is being performed, other outputs are in OFF status. ORP values are retained.

Manual Cleansing Mode

By pressing the and keys simultaneously for 3 seconds, the units enters Manual cleansing mode. In Manual cleansing mode, cleansing action is performed using “Cleansing time” and “Restore time after cleansing”. After cleansing action is complete, the unit automatically reverts to Cleansing Output mode. Manual cleansing mode (by keypad operation) will not be accessible if programmed cleansing is currently being performed. During Manual cleansing mode, if programmed cleansing action initiates after restore time has passed, the programmed cleansing action will not be performed in the current session.

ORP Input Error Alarm

Detects actuator trouble. Even if ORP input error alarm time has elapsed, and if ORP input does not become higher than ORP input error alarm span, the unit assumes that actuator trouble has occurred, and writes Status flag 2. In Serial communication, status can be read by reading Status flag 2 (EVT1, EVT2, EVT3, EVT4 output flags). If (ORP input error alarm output) is selected in [EVT1 type (p.23)], EVT1 output is turned ON. The same applies to EVT2, EVT3 and EVT4.

ORP input error alarm is disabled in the following cases:

• During Adjustment mode or Span sensitivity correction mode

• When (Cleansing output) is selected in any of EVT1 to EVT4 type (p. 23, 29, 35, 41), and cleansing is performing using the ‘Cleansing time’ and ‘Restore time after cleansing’ settings.

• When ORP input error alarm time is set to 0 seconds (or minutes) or ORP

input error alarm span is set to 0 mV.
