33 Glossary

Parameters which apply to both output K1 and K2 (e.g. tAb1 or
tAb2) are only explained once.

Term

Parameter

Explanation

Actuator time

The value for this parameter must be taken from the specific
data for the actuator device (e.g. an motorized valve).

Alarm contact

With limit control, the active time of the outputs K1 or K2 can be
monitored

(dosing monitoring)

. If the active time exceeds an

adjustable value (

Alarm delay AL2

), then the alarm contact is

activated.

With pulse width or pulse frequency control, the size of the
control deviation is monitored. If the control deviation exceeds
the adjustable

Alarm tolerance AL1

, and remains outside this

tolerance for longer than the

Alarm delay AL2

then the alarm

contact is activated.

Alarm delay

AL2

If the control deviation exceeds the adjustable

Alarm tolerance

AL1

, and remains outside this tolerance for longer than the

adjustable Alarm delay AL2,

then the alarm contact is activated.

Alarm tolerance

AL1

If the process value goes above or below the value of setpoint
plus/minus alarm tolerance (x > SPr..+AL1 or x < SPr..-AL1) and
remains outside these limits for longer than the

Alarm delay

then the alarm contact is activated.

The alarm tolerance is only active if pulse width or pulse
frequency control has been configured,

➩

Chapter 26.4 “Controller options - C211”, page 76.

If limit control is configured, then the values for the
alarm tolerance will be ignored.
