The GPRESALM alarm can be blockedby activating the BLKALM input.If the pressure drops further to a very low level, the PRESLO binary input goes high,activating the lockout alarm GPRESLO after a time delay set with the tDGasPresLOsetting. The GPRESLO alarm can be blocked by activating the BLKALM input.The binary input BLOCK can be used to block the function. The activation of theBLOCK input deactivates all outputs and resets internal timers. The alarm signals fromthe function can be blocked by activating the binary input BLKALM.16.4.8 Technical dataGUID-B6799420-D726-460E-B02F-C7D4F1937432 v8Table 414:SSCBR Technical dataFunction Range or value AccuracyAlarm level for open and closetravel time(0 – 200) ms ±3 msAlarm level for number ofoperations(0 – 9999) -Independent time delay forspring charging time alarm(0.00 – 60.00) s ±0.2% or ±30 ms whichever isgreaterIndependent time delay for gaspressure alarm(0.00 – 60.00) s ±0.2% or ±30 ms whichever isgreaterIndependent time delay for gaspressure lockout(0.00 – 60.00) s ±0.2% or ±30 ms whichever isgreaterCB Contact Travel Time, openingand closing±3 msRemaining Life of CB ±2 operationsAccumulated Energy ±1.0% or ±0.5 whichever isgreaterSection 16 1MRK 511 408-UUS AMonitoring546 Phasor measurement unit RES670 2.2 ANSITechnical manual
