value. This fact adds a noise of typ. ±30 ppm which has to be considered in terms of accuracy. From the principle of measurement, the measured value of CO concentration depends on the value of air pressure - altitude at the installation site. For this reason, it is suitable for accurate measurement to set the altitude of the installation site by TSensor software. -

Low limit „Lo“ – the relay closes when measured value falls below preset „low limit” for longer time than preset „delay time“. Relay goes open when measured value exceeds „low limit“ value plus the „hysteresis” value. See example. Low limit „Lo“ Delay [s] Hysteresis 5.5. -

5.5.2. Setting with using regulator keys If „Actual regulator preset” is displayed, it is possible to enter into edit mode and edit displayed value by pressing „SET“ key. You can edit selected value if right password is entered. During value editing there is range check executed and edited value is still compared with limits for corresponding value (range). - Page 11 Acoustic alarm deactivation activated acoustic alarm is possible to acoustic alarm is still activated for all time and deactivate by pressing „ESC“ key it is impossible to deactivate it Relay response for error Regulator continuously checks its state during operation. In case error of assigned value measurement is found then output relay: stays unchanged (in previous status) Relay1 switch OFF...
- Page 12 measurement mode selection This item provides to choice if measured value is displayed and read in “SLOW” or “FAST” mode. “FAST” mode provides last measured value without averaging; this means that no software filter is used for calculating the output value. “SLOW” mode provides value averaged from last 11 measured values.
