- The relay can be energized or de-ener- gized in alarm state (selection via key- board).
- The outputs can be assigned to alarm setpoints directly or via logic functions (AND, OR).
- The outputs can be delayed or assigned to a hysteresis value (selectable in engi- neering units).
- 4 (10) alarm setpoints settable in abso- lute value, with functions configurable via keyboard (direct, reverse, deviation, sym- metrical deviation).
- Setpoint can be set over the entire selected
- Minimum or maximum setpoint with
- Setpoint can be excluded in power-up phase until the input variable has excee- ded the set
A subsequent drop below such limit cau- ses the relay to trip
