ALL Setting Alarms
This menu lets you configure parameters for the alarm functions.
Reference quantity
0 IN1
1 IN2
2 IN3
3 IN4
4 Fin.A (math function A)
5 Fin.b (math function b)
6 PV - Process Variable (input selected in SPU)
7 SSP - Active Setpoint
8 SP - Local Setpoint
9 DEV - Deviation (PV - SSP) (only for absolute type)
10 CO1 (control output 1)
(scale range like the power 0 ÷ 100.0 % and 0 ÷ -100.0 %)
11 CO2 (control output 2)
(scale range like the power 0 ÷ 100.0 % and 0 ÷ -100.0 %)
12 Value acquired from serial line
13 Max peak input 1
14 Min peak input 1
15 Input 1 peak - peak
16 Max peak input 2
17 Min peak input 2
18 Input 2 peak - peak
Select reference quantities
Alarm n
Alarm n type
By adding the following numbers to the value shown in the table,
you can enable a series of supplemental functions:
+8: disable power-on until first trip point.
+16: enable memory latch.
+32: change color of PV display in case of active alarm
+256: change color of PV display if limit is exceeded
(only for alarms with timed delay)
+512: enable string if alarm is active
+1024:enable string if limit is exceeded (only for alarms with timed
delay)
N.B.:
For deviation alarms, reference quantities must have the same
decimal resolution
