Protective Wiring of Relay Contacts

Relay contacts are subject to electrical erosion. Especially with inductive and capacitive loads, the service life of the contacts will be reduced. For suppression of sparks and arcing, components such as RC combinations, nonlinear resistors, series resistors, and diodes should be used.

Typical AC applications with inductive load

Load1 RC combination,2

e.g. RIFA PMR 209 Typical RC combinations for 230 V AC: capacitor 0.1 µF / 630 V, resistor 100 Ω / 1 W

Protective Wiring of Relay Contacts

A: DC application with inductive load B: AC/DC applications with capacitive load C: Connection of incandescent lamps

Make sure that the maximum ratings of the relay contacts are not exceeded even during switching!

Diagnostics

Display of calibration data, display of sensor data, performing a device self-test, viewing the logbook entries, display of hardware/software versions of the individual components. The logbook can store 100 events (00...99). They can be displayed directly on the device. The logbook can be extended to 200 entries using a TAN (Option).

HOLD

Manual activation of HOLD mode, e.g. for replacing a digital sensor. The signal outputs adopt a de ned state.

Calibration

Every sensor has typical characteristic values, which change in the course of the operating time. Calibration is required to supply a correct measured value. The device checks which value the sensor delivers when measuring in a known solution. When there is a deviation, the device can be “adjusted“. In that case, the device displays the “actual“ value and internally corrects the measurement error of the sensor. Calibration must be repeated at regular intervals. The time between the calibration cycles depends on the load on the sensor. During calibration the device is in HOLD mode.

During calibration the analyzer remains in the HOLD mode until it is stopped by the operator.

Con guration

The analyzer must be con gured for the respective measurement task. In the “Con guration“ mode you select the connected sensor, the measuring range to be transmitted, and the conditions for warning and alarm messages. During con guration the device is in HOLD mode.

Con guration mode is automatically exited 20 minutes after the last keystroke. The device returns to measuring mode.

HOLD Mode

The HOLD mode is a safety state during con guration and calibration. Output current is frozen (Last) or set to a  xed value (Fix). Alarm and limit contacts are disabled. The HOLD mode is indicated by orange display backlighting.

Terminating the HOLD Mode

The HOLD mode is ended by switching to measuring mode (hold meas key depressed). The display reads “Good Bye“, after that, the HOLD mode is exited. When the calibration mode is exited, a con rmation prompt ensures that the installation is ready for operation (e.g.: sensor reinstalled, located in process).

Output Signal Response

Last:• The output current is frozen at its last value. Recommended

for short con guration procedures. The process should not change decisively during con guration. Changes are not noticed with this setting! Fix:• The output current is set to a value that is noticeably di erent from the process value to signal the control system that the device is being worked at.

Alarm

Manual Activation of HOLD

The HOLD can be activated manually from the HOLD menu. This allows checking or replacing a sensor, for example, without provoking unintended reactions of outputs or contacts. Press meas key to return to selection menu.

Alarm

When an error has occurred, Err xx is displayed immediately. Only after expiry of a user-de ned delay time will the alarm be registered and entered in the logbook. During an alarm the display blinks, the display backlighting turns red.

Error messages can also be signaled by a 22 mA output current (see Con guration). The alarm contact is activated by alarm and power failure, see also “Con guration / Alarm Settings“. 2 sec after the failure event is corrected, the alarm status will be deleted.

External Activation of HOLD

The HOLD mode can be activated from outside by sending a signal to the Hold input (e.g. from the process control system).

Configuration

Menu Structure of Con guration

The device provides 2 parameter sets “A“ and “B“. By switching between the parameter sets you can adapt the device to different measurement situations, for example. Parameter set “B“ only permits setting of process-related parameters. The configuration steps are assigned to different menu groups. Using  and  you can jump between the individual menu groups. Each menu group contains menu items for setting the parameters. Pressing enter opens a menu item. The values are edited using  and . Pressing enter confirms/stores the settings. Return to measurement: Press meas.

Please note:

The  lter only acts on the current output, not on the display, the limit values, or the controller! During HOLD the  lter is not applied. This prevents a jump at the output.

Pulse Frequency Controller ( PFC)

The pulse frequency controller is used to operate a frequency c

Calibration

Please note:

All calibration procedures must be performed by trained person-• nel. Incorrectly set parameters may go unnoticed, but change the measuring properties.

The response time of the sensor and temperature probe is • considerably reduced when the sensor is  rst moved about in the bu er solution and then held still.

The device can only operate properly when the bu er solutions • used correspond to the con gured set. Other bu er solutions, even those with the same nominal values, may demonstrate a di erent temperature response. This leads to measurement errors.

When using ISFET sensors or sensors with a zero point other than pH 7, the nominal zero point must be adjusted each time a new

sensor is connected. This is important if you want to obtain reliable Sensoface messages. The Sensoface messages issued during all further calibrations are based on this basic calibration.

Calibration is used to adapt the device to the individual sensor characteristics, namely asymmetry potential and slope. Access to calibration can be protected with a passcode (SERVICE menu). First, you open the calibration menu and select the calibration mode:

Product calibration

Product Calibration (pH)

Calibration by sampling (one-point calibration). During product calibration the sensor remains in the process. The measurement process is only interrupted brie y.

Procedure:

The sample is measured in the lab or directly on the site using a por-1) table meter. To ensure an exact calibration, the sample temperature should correspond to the measured process temperature. During sampling the device saves the currently measured value and then returns to measuring mode. The “calibration“ mode indicator blinks. In the second step you enter the measured sample value in the 2) device. From the di erence between the stored measured value and entered sample value, the device calculates the new asymmetry

potential. If the sample is invalid, you can take over the value stored during sampling. In that case the old calibration values are stored. Afterwards, you can start a new product calibration.

Display Action Remark

Select product calibration: P_CAL. Press enter to proceed.

ORP ( Redox) Calibration

The potential of a redox sensor is calibrated using a redox (ORP) bu er solution. In the course of that, the di erence between the measured potential and the potential of the calibration solution is determined according to the following equation. During measurement this di erence is added to the measured potential.

The sensor potential can also be related to another reference system – e.g. the standard hydrogen electrode. In that case the temperaturecorrected potential (see table) of the reference electrode used must be entered during calibration. During measurement, this value is then added to the ORP measured. Please make sure that measurement and calibration temperature are the same since the temperature behavior of the reference electrode is not automatically taken into account.
