Alarm inverse
Selects limit value and fault monitoring. In the event of
device errors or incorrect input values (see error limits
Range 1 to 4 in Section 6.3.11), the relays are
switched in accordance with the failsafe mode
configured in Rel. Mode (see Section 6.3.11).
• Min: minimum with hysteresis (see Page 38)
• Max: maximum with hysteresis (see Page 39)
• Grad: gradient (see Page 40)
• In band: validity range within two values
• Out band: validity range outside of two values
• Alarm: relay is used as an alarm relay
• Alarm inverse: Relay is used as an alarm relay; the
switching behaviour of the relay is safety-oriented
such that the relay drops out in the case of a power
supply failure or a device malfunction.
Dec. point
XXXXX
XXXX.X
XXX.XX
XX.XXX
X.XXXX
Number of digits after the decimal point for the limit
value.
Setpoint A
-99999 to 99999
0.0
Measured value at which a change in the switch status
occurs (slope for gradient). Default: 0.0
Setpoint B
-99999 to 99999
99999
The second setpoint can be configured for the "In band"
and "Out band" operating modes and is only visible if
one of these two functions was selected for this relay.
Hysteresis
-99999 to 99999
99999
For entering the hysteresis for the threshold at
minimum/maximum as an absolute value.
Delay
0 to 99
0
Sets the limit value event delay once the threshold is
reached (in seconds) (see Page 41).
Alternate
No
Yes
Determines the switching function for this relay:
• No: no alternating function; switch point
permanently assigned to relay
• Yes: alternate function (see Page 42)
!
Note!
Relays 1-4 can be used for the alternating function.
