26 Operating Modes 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 ( ). 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 servicing. The signal outputs adopt a defined state. Calibration Every sensor has typical characteristic values. 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. During calibration the device is in HOLD mode. During calibration the analyzer remains in the HOLD mode until it is stopped by the operator. Configuration The analyzer must be configured for the respective measurement task. In the Configuration mode you select the connected sensor, the measuring range to be transmitted, and the conditions for warning and alarm messages. During configuration the device is in HOLD mode. Configuration mode is automatically exited 20 minutes after the last keystroke. The device returns to measuring mode.

28 HOLD Mode The HOLD mode is a safety state during configuration and calibration. Output current is frozen (Last) or set to a fixed value (Fix). Alarm and limit contacts are disabled. The HOLD mode is indicated by orange display backlighting. HOLD mode, display icon: Output Signal Response Last: The output current is frozen at its last value. Recommended for short configuration procedures. The process should not change decisively during configuration. Changes are not noticed with this setting! Fix: The output current is set to a value that is noticeably different from the process value to signal the control system that the device is being worked at. Output Signal During HOLD: Output current [ma] 21 Output signal for HOLD FIX setting = 21.0 ma Output signal for HOLD LAST setting 4 HOLD active HOLD active 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 confirmation prompt ensures that the installation is ready for operation (e.g.: sensor reinstalled, located in process). 28

29 Alarm 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). HOLD Power supply V AC/DC 10 input Stratos Pro A4...

71 Controller Functions Pulse Length / Pulse Frequency Controller Pulse Length Controller ( PLC) The pulse length controller is used to operate a valve as an actuator. It switches the contact on for a time that depends on the controller output. The period is constant. A minimum ON time of 0.5 sec is maintained even if the controller output takes corresponding values. Output signal (relay contact) of pulse length controller ON time (Y = 20 %) ON time (Y = 80 %) Pulse length Pulse Frequency Controller ( PFC) The pulse frequency controller is used to operate a frequencycontrolled actuator (metering pump). It varies the frequency with which the contacts are switched on. The maximum pulse frequency [pulses/min] can be defined. It depends on the actuator. The contact ON time is constant. It is automatically calculated from the user-defined maximum pulse frequency: Output signal (relay contact) of pulse frequency controller ON time Pulse frequency (Y = 20%) Pulse frequency (Y = 80%) 71
