Description
The parameter sets the alarm type for generic alarms AL1...AL8 of modules GPC-M, GPC-E1 and GPC-E2. The alarm and module con-
cerned depend on the address used.
Options:
Index
Direct (maximum) or
Reverse (minimum)
Absolute or Relative
Normal or Symmetri-
cal (window)
0 Direct Absolute Normal
1 Reverse Absolute Normal
2 Direct Relative * Normal
3 Reverse Relative * Normal
4 Direct Absolute Symmetrical
5 Reverse Absolute Symmetrical
6 Direct Relative * Symmetrical
7 Reverse Relative * Symmetrical
Increasing the index by a fixed amount results in the following behaviours:
Index +8 = The alarm is disabled from startup until the alarm threshold is first intercepted.
Index +16 = Alarm memory is enabled.
Index +32 = A1.t becomes the alarm activation delay time (0...999 minutes)
This does not apply to the symmetrical absolute.
Index +64 = A1.t becomes the alarm activation delay time (0...999 seconds).
This does not apply to the symmetrical absolute.
Index +128 = Alarm is disabled during softstart.
Notes:
*) Setting not available for generic alarm 1.
The relative alarm type refers to the immediately preceding absolute alarm with index 1...8.
Examples:
Setting 20 (= 4 + 16) provides a direct, absolute and symmetrical alarm that is only enabled when the alarm threshold is exceeded for the
first time since startup.
If AL1 and AL2 are absolute, by setting AL3 as relative, alarm 3 will be relative to alarm 2.
