Function of limit 1/2/3 1
0 switched off
1 measured value monitoring
2 Measured value monitoring + alarm latch. A latched limit
value can be reset via error list or via a digital input, or by
pressing key Ò or è (-> LOGI/ Err.r)

Source of Limit 1/2/3 1
0 process value
1 control deviation xw (process value - set-point)
2 Control deviation Xw (=relative alarm) with suppression after
start-up and setpoint change
After switch-on or setpoint change, alarm output is suppressed,
until the process value was within the limits once. At the latest after
elapse of time 10 ti1 the alarm is activated. (ti1 = integral
time 1; parameter r Cntr)
ti1 switched off (ti1 = 0) is considered as Î , i.e. the alarm
is not activated, until the process value was within the limits once.
3 measured value INP1
4 measured value INP2
5 measured value INP3
6 effective setpoint Weff
7 correcting variable y (controller output)
8 control variable deviation xw (actual value - internal setpoint)
= deviation alarm to internal setpoint
9 difference x1 - x2 (utilizable e.g. in combination with process value
function “mean value” for recognizing aged thermocouples
11 Control deviation (=relative alarm) with suppression after
start-up and setpoint change without time limit
After switch-on or setpoint change, alarm output is suppressed,
until the process was within the limits once.
HC.AL
Alarm heat current function (INP2) 0
0 switched off
1 Overload short circuit monitoring
2 Break and short circuit monitoring
LP.AL
Monitoring of control loop interruption for heating (see page 69) 0
0 switched off / inactive
1 LOOP alarm active. A loop alarm is output, unless the process
value reacts accordingly after elapse of 2 x ti1 with
Y=100%.
With
ti1=0 , the LOOP alarm is inactive.
dAc.A
DAC alarm function (see page 69) 0
0 DAC alarm switched off / inactive
1 DAC alarm active
