3.4 Wiring Safety Information

When making any wiring connections to the instrument, the following warnings and notes must be adhered to, as well as any warnings and notes found throughout the individual installation sections. For more safety information refer to section 2.1 on page 11.

DANGER Always disconnect power to the instrument when making any electrical connections.

Electrostatic Discharge (ESD) Considerations

To minimize hazards and ESD risks, maintenance procedures not requiring power to the analyzer should be performed with power removed.

Delicate internal electronic components can be damaged by static electricity, resulting in degraded instrument performance or eventual failure.

The manufacturer recommends taking the following steps to prevent ESD damage to the instrument:

• Before touching any electronic components (such as printed circuit cards

and the components on them) discharge static electricity from the body by touching an earth-grounded metal surface such as the chassis of an instrument or a metal conduit or pipe.

• To reduce static build-up, avoid excessive movement. Transport static-

sensitive components in anti-static containers or packaging.

• To discharge static electricity from the body and keep it

discharged, wear a wrist strap connected by a wire to earth ground.

• Handle all static-sensitive components in a static-safe area. If

possible, use anti-static floor pads and work bench pads.

6.2.2 Standard analog input block (AI)

Three Analog Input Function Blocks provide for cyclic transmission of measured values (currently measured value with status, alarm limits, freely selectable process parameter).

6.2.2.1 Operating modes

Use the MODE_BLK parameter to set the following operating modes:

• OOS—out of service. If not write-protected, access to all

parameters is allowed.

• MAN—manual

• Auto—online, normal state

6.2.2.2 Set the parameter and units

Use CHANNEL to set the measured parameter and units (Table 15). The corresponding measurement unit is selected in the UNITS subparameter of XD_SCALE (Table 16 on page 51).

6.2.2.3 Data processing

Use the L_TYPE parameter to apply a linearization function to the data.

• Direct—data is sent directly from the TB to the AI without processing. The units for the XD_SCALE and OUT_SCALE parameters must be identical.

• Indirect—data from the TB is linearly scaled from the input scale (XD_SCALE) to the output scale (OUT_SCALE).

• Indirect square root—data is rescaled from the input scale (XD_SCALE) and recalculated using a root function. Then the value is linearly scaled to the output scale (OUT_SCALE).

6.2.2.4 Alarms

The AI block can generate block alarms and limit alarms. Use the ACK_OPTION parameter to specify if an alarm must be acknowledged. When the measured value status is “bad”, the AI block BLOCK_ERR parameter indicates an Input Failure.

• Block alarms—a block error will be reported via the BLOCK_ERR parameter (simulate active, input failure, block configuration error, out of service (OOS)). The BLOCK_ALM parameter sends the alarm status to the control system.

• Limit alarms—the measured value OUT falls outside of the limit values (HI_HI_LIM, HI_LIM, LO_LIM, LO_LO_LIM).

If an alarm occurs, evaluate the following bus parameters:

• OUT parameter (currently measured value) in the Al block

• LAST_ERROR parameter in the transducer block

• SENSOFACE_STATUS parameter in the transducer block

6.2.4 Calibration via Foundation Fieldbus

The transmitter can be calibrated via Foundation Fieldbus using the comparison or grab sample method.

1. Make sure the system is configured for the value that is measured:

• Dissolved oxygen: PRIMARY_VALUE_TYPE = DO_mg/l, DO_ppm, DO_µg/l, DO_ppb or DO_% APPLICATION = Dissolved oxygen CALIBRATION_MODE = Conc or Sat

• Gaseous oxygen: PRIMARY_VALUE_TYPE = GAS_ppm or GAS_% APPLICATION = Measurement in gases CALIBRATION_MODE = Conc or Sat

2. Collect a grab sample and set CAL_SAMPLE_PRD to sample. The measured value of the sample is stored. After writing, the parameter is automatically reset to NOP (no operation).

3. Read the parameter CAL_SAMPLE_PRD_STORED_VAL. It contains the stored value.

4. Measure the grab sample and write the lab value in CAL_PRODUCT. The device is now calibrated. CAL_SAMPLE_PRD_STORED_VAL is reset to zero.

Note: The calibration values can also be entered directly in the parameters CAL_ZERO and CAL_HIGH.

7.2 Profibus PA communication

Profibus PA uses a master/slave data exchange technique. The master (typically a PLC) generates queries to individual slaves. The slaves, in turn, reply back with a response to the master. A Profibus message contains the information required to send a query or request, including the slave address, function code, data, and a checksum. See Table 20

on page 67 for Profibus communication parameters.

Section 8 Calibration

8.1 Calibration

The transmitter is adjusted to the sensor through the calibration. The available calibration methods are shown in Table 21. Calibrate the sensor in air when the sensor can be removed from the process. The sensor will stabilize more quickly in air.

When the sensor cannot be removed from the process (e.g. sterile processes), the process medium must be aerated during calibration (e.g. after sterilization).

Table 21 Calibration methods and passcodes

Method Passcode

Zero calibration 1001 Temperature probe adjustment 1015 Zero/slope display 0000 Calibration in air or water 1100 Calibration by product comparison 1105

During calibration the transmitter remains in the Hold mode for safety reasons. The loop current is frozen at the value specified in the o1.HoLD menu option. The Sensoface icon is inactive. The calibration mode indicator is displayed (Figure 12 on page 33).

To exit the calibration mode at any time, press The output current will be held for 20 seconds and the measured value will be displayed.

Note: Calibrations must be performed by trained personnel. Incorrectly set parameters may result in errors in sample measurements.

Calibration

8.1.1 Zero calibration

Perform a zero calibration as the first point whenever a 2-point calibration is required.

Note: The DO sensor models SE 704, SE 705 and InPro6000 have a very low zero current. Therefore a zero calibration is only recommended for measurement of oxygen traces.

Allow the sensor to stabilize in the calibration medium for at least 10 to 30 minutes (InPro6900 at least 60 minutes). A drift check will not be made. The zero current of a properly functioning sensor is notably less than 0.5% of the current in air.

The display will not change until an input current is entered for the zero point. When measuring in an oxygen-free medium, the displayed current can be taken directly.

Complete the following steps to set the zero point.

Section 13 Warranty, liability and complaints

The manufacturer warrants that the product supplied is free of material and manufacturing defects and undertakes the obligation to repair or replace any defective parts at zero cost.

The warranty period for instruments is 24 months. If a service contract is taken out within 6 months of purchase, the warranty period is extended to 60 months.

With the exclusion of the further claims, the supplier is liable for defects including the lack of assured properties as follows: all those parts that can be demonstrated to have become unusable or that can only be used with significant limitations due to a situation present prior to the transfer of risk, in particular due to incorrect design, poor materials or inadequate finish will be improved or replaced, at the supplier's discretion. The identification of such defects must be notified to the supplier in writing without delay, however at the latest 7 days after the identification of the fault. If the customer fails to notify the supplier, the product is considered approved despite the defect. Further liability for any direct or indirect damages is not accepted.

If instrument-specific maintenance and servicing work defined by the supplier is to be performed within the warranty period by the customer (maintenance) or by the supplier (servicing) and these requirements are not met, claims for damages due to the failure to comply with the requirements are rendered void.

Any further claims, in particular claims for consequential damages cannot be made.

Consumables and damage caused by improper handling, poor installation or incorrect use are excluded from this clause.

The manufacturer process instruments are of proven reliability in many applications and are therefore often used in automatic control loops to provide the most economical possible operation of the related process.
