OCM F - rev. 05 / 06.04.2018 page 67
regulating deviation.
>Flow quick
close< “Flow quick close” acts as OR-parameter re-
lated to “Level quick close”. This parameter
defines the desired maximum flow rate of the
medium.
“Time quick close” will be activated as soon as
this value has been reached.
Depending on application; this parameter shall
be set approx. 10…50 % higher than the con-
dition which makes the system go to regulator
mode during dry weather operation.
Before setting this parameter observe the unit
set point deviation tolerance.
>Time quick
close< “Time quick close” is the time the regulating
unit needs to move from open condition to the
position it has whilst being in normal regulator
mode. “Level quick close” or “Flow quick
close” are the conditions for “Time quick close”
to switch.
>Time of pos
closed< This period is for error cases, e. g. interrupted
sensor communication or defect sensor. In this
case the regulating unit goes to closed condi-
tion before it opens again for the period set in
this parameter “Time of pos closed”.
>Time delay<
This is the time to elapse before the position
control comes into effect in case of errors.
The adjustable range is 0…240 seconds.
