30. ximal recommended length of the reference period is around one week The maximal registered values can be browsed using the UL option To set up the thresholds it is necessary define the safety factor in the Ur option for the warning threshold and Ar for alarm Usually the Ur factor is at 1 5 level while Ar at 2 The automatic set up of the thresholds can be done in the OA option by selecting the SU and SA options In case when the product of the maximal registered value and the safety factor exceeds the measurement range the thresholds is disabled For this reason it is recommended to browse the maximal values before enabling the automatic threshold setting to avoid disabling some thresholds by accident The alarming system includes indication of sensor failures The CU and CA options allow enabling warning and alarm when a sensor failure is detected The FU and FA options allow enabling warning and alarm when measurement conditions set in the UU option are not fulfilled It is not recommended to enable the FA option as it will activate the shutdown alarm when the machine is turned off due to the missing phase marker signal This can make it impossible to turn the machine on again In the alarming system it is possible to define two kinds of delays One of them is alarm system activation delay after the machine s start up the Uo option while the other is alarm activati
