When the value of an internal limiting value (12) changes from "0" to "1", the parameter value of
the switch-on delay is evaluated. When the value of an internal limiting value changes from "1"
to "0", the parameter value of the switch-off delay is evaluated. If "no delay" is set, then the
value of the delayed internal limiting value immediately takes the value of the internal limiting
value. When a delay time is set, a timer with the delay time (13) is loaded and started. Only
when it expires is the value of the internal limiting value accepted as the value for the delayed
internal limiting value (14) and the limiting value sent in accordance with the parameterisation.
The cyclic sending is also affected by this delay. If the internal limiting value changes before the
timer expires, then it is stopped and the limiting value remains unchanged. Consequently, no
limiting value telegram, triggered by the parameter "Transmission on change of the limiting
value object", is transmitted either.
Setting the switch-on delay
A switch-on delay can be set for all limiting values by means of the parameter "Switch-on delay
internal limiting value object".
"n limiting values active" is set for the measured value on the parameter page "CO2
measurement" or "humidity measurement".
o In the parameter ""Switch-on delay for internal limiting value object", select the appropriate
value from the list.
The switch-on delay is set.
Setting the switch-off delay
An internal switch-off delay can be set for all limiting values by means of the parameter "Switch-
off delay for internal limiting value object".
"n limiting values active" is set for the measured value on the parameter page "CO2
measurement" or "humidity measurement".
o In the parameter "Switch-off delay for internal limiting value object", select the appropriate
value from the list.
The switch-off delay is set.
