Temperature
Type
Float
This parameter returns the internal temperature in the instrument housing in °C, which is an approximation of the actual media
temperature.
4.3.1.1 Advanced measurement and control
Setpoint Slope
Type
Unsigned int
The value of this parameter represents the time it would take to adjust the setpoint if it were changed from 0 to 100%. This
feature can be used to smooth 'nervous' controller behavior, e.g. to reduce setpoint overshoot or undershoot.
The supported range corresponds to 0...3000 seconds. Default value = 0.
Example:
If Setpoint Slope = 100 it will take 10 seconds to adjust the setpoint if it is changed from 0 to 100%. A setpoint change of 20% will
take (20%/100%)*10 seconds = 2 seconds.
Valve Output
Type
Unsigned long
This parameter represents the controller output signal for control valve operation.
Controller Speed
Type
Float
This parameter sets the overall controller speed factor for the selected fluid set. Controller Speed is set ex factory between value
'0.5' (slow) and '2' (fast). The default value is '1'. Slower or faster settings are possible between values 0.2 and 5 at the customer's
responsibility.
4.3.2 Alarms
Alarm settings are most easily accessible using Bronkhorst FlowSuite, FlowPlot or FlowView or a Bronkhorst® readout
and control unit.
The built-in alarm functionality can be used to handle different alarm types:
· system errors and warnings
· min/max alarms
response alarms
·
· batch alarms
· master/slave alarms
The alarm type can be set with parameter Alarm Mode. When an alarm is activated, the type can be read out using parameter
Alarm Info. An automatic setpoint change can be set using the parameters Alarm Setpoint Mode and Alarm New Setpoint. It is also
possible to set an alarm delay, to prevent overreaction to small disturbances, using parameter Alarm Delay Time. The methods
by which an alarm can be reset are controlled by Reset Alarm Enable.
