User manual - METER SRT-N118-XA 4.2. ASSEMBLY - Disconnect the power supply prior to starting assembly. - Check the connections are wired correctly prior to switching the unit on. To install device on the wall, a pinholes should be made. Figure 4.1 presents dimensions of the device and distances between holes. - Page 9 User manual - METER SRT-N118-XA - In order to secure against accidental short circuit the connection cables must be terminated with appropriate insulated cable tips. - Tighten the clamping screws. The recommended tightening torque is 0.5 Nm. Loose screws can cause fire or defective operation. Over tightening can lead to damaging the connections inside the units and breaking the thread.

Page 18: Detection Of The Peak Values
6.2. DETECTION OF THE PEAK VALUES The SRT-N118-XA controller is equipped with peaks detection function. It can detect a peaks of the input signal and display their values. Presets connected with this function are placed in ”HOLd” menu (see description of ”HOLd” menu). The detection of the peak can be done if the measured signal raises and drops of value at least equal to parameter ”PEA”... -

While the controlling process, the relay output changes his state depends of both “SEtP” and “SEt2” thresholds in similar way as it was described in one threshold mode. If two threshold mode is used, “modE” parameter defines state of the relay output when the input value occurs in a particular zone defined by border values of both thresholds . -
