23.1.6 Damping and smoothing Damping and smoothing are both filter functions, which are configurable, and have different effects on the way the input signal is processed. • Damping causes conventional single-pole, low-pass filtering that is similar to an R-C network. • Smoothing causes a more 'intelligent' damping where small changes (noise) are heavily suppressed and large (tendency) changes are processed normally. Although, high damping values will greatly suppress noise and make the output signal stable, it causes a slow response time. The smoothing function avoids this disadvantage by removing the filtering while there are very large signal changes on the input. Higher damping values are recommended for slow input signals requiring high levels of stability, while fast signals require lower damping values. If in doubt, some experimentation will yield the best results. 23.1.7 Alarm signals Alarm signals can be configured to drive analog output currents outside the working range. • The low alarm changes the output current to 1.00 mA and • The high alarm changes the current to 21.00mA. There are three types of fault that trigger an alarm response: • O/C Alarm - alarm is signaled if an open circuit in the field is detected. • Tx Fail - alarm signaled if a fault is detected. • Cj Fail - alarm signaled if a fault is detected with the Cj sensor. Meanwell power system To monitor the DC voltage, a free relay contact is provided labeled as 'DC OK.'
