h-quick close
h-quick close acts as OR-parameter related to Q-quick close. This parameter
defines the desired maximum flow level of the medium. “t-quick close” will be
activated as soon as this value has been reached. Depending on application,
this parameter shall be set approx. 60-80 % higher than the setpoint. Before
setting this parameter please observe waves at the measurement place as
well as the unit’s regulating deviation.
Q-quick close
Q-quick close acts as OR-parameter related to h-quick close. This parameter
defines the desired maximum flow rate of the medium. “t-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 condition which
makes the system go to regulator mode during dry weather operation. Before
setting this parameter please observe the unit setpoint deviation tolerance.
t-quick close
t-quick close is the time the regulating unit needs to move from open condition
(end switch: PATH ON) to the position it has whilst being in normal regulator
mode. “h-“ or “Q-quick close” are the conditions for “t-quick close” to switch.
t 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 condition (end switch:
PATH OFF) before it opens again for the period set in this parameter t 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.

WARNING
Data loss due to system reset
Selecting >system reset< is going to reset the system to the basic parameter
settings. The default settings are going to be restored and all customer modifi-
cations will be set to default condition (system general reset).

Setup parameter – submenu
This menu allows to modify measurement and output damping, to reset the sys-
tem to default condition as well as to modify special settings by using the service
code.
System reset
Enables a general reset of the measurement transmitter. Entering the PIN-
Codes >2718< will cause the OCM F to execute a general reset. The unit will
be in initialising mode subsequently which requires the operation language to
be set.
