Alarm type 1/2 (xx.A1m/xx.A2m)
Figure 4: Setting the alarm functions
High alarm (HiAL)
Alarm when the positive limit value is exceeded (after the alarm delay time has
elapsed), not taking the hysteresis into account (see Figure, 4 Pos. 1). Reset
conditions: Going below the positive limit value - hysteresis.
Low alarm (LoAL)
Alarm when the negative limit value is gone below (after the alarm delay time has
elapsed), not taking the hysteresis into account (see Figure 4, Pos. 3). Reset
condition: Exceeding the negative limit value + hysteresis.
Limit value alarm 1/2 (xx.A1L/xx.A2L)
The limit value for the selected alarm type 1 and 2 is set here (see Figure, 4 Pos.
4 and Pos. 6).
Hysteresis (xx.HYS)
Hysteresis is the gap between the set limit value alarms. 1 or 2 is always set as a
positive value for the Max. and Min. alarm (see Figure, 4 Pos. 5).
Alarm delay (xx.ALd)
This parameter is used to suppress short-term faults (see Figure 4, Pos. 2). The
alarm signal is only activated after the set time has elapsed and the limit value
overrange or underrange is still pending.
