Units
Configuration of the units for the totalizers and process variables.
!
Note!
The units are automatically preset depending on the system unit selected (Setup: Basic set-up →
System eng. units).
Important system units are defined in Section 11 of these Operating Instructions.
Flow direct. Constant
Changing
Information on the direction of flow in the circuit with
bidirectional operation.
!
Note!
Only for the Bidirectional operating mode.
Dir. signal Terminals Terminal for connecting the direction signal output of the flow
transmitter.
!
Note!
Only for the Bidirectional, Changing flow direction operating
mode.
Flow Select
Flow 1-3
Assign a flow sensor to your application. Only the sensors that
were configured previously (see ’Setup: Inputs - Flow inputs’)
can be selected here.
Inst. point Warm
Cold
Set the 'thermal’ installation point at which the flow sensor is
located in your application (only active for water/heat
difference or liquid heat difference).
The installation point is specified as follows for steam/heat
difference:
Heating: warm (i.e. steam flow)
Steam generation: cold (i.e. water flow)
!
Note!
In the event of bidirectional operation, make the settings as per
the heating operating mode.
Mean pres. 10.0 bar Indicates the average process pressure (absolute) in the heating
circuit.
!
Note!
Only for water applications.
Temperature
cold
Select
Temperature 1-6
Assign the sensor which records the lower temperature in your
application. Only the sensors that were configured previously
(see ’Setup: Inputs - Temperature inputs’) can be selected here.
!
Note!
Only for heat diff. applications.
Temperature
Warm
Unused
Temperature 1-6
Assign the sensor which records the higher temperature in
your application. Only the sensors that were configured
previously (see ’Setup: Inputs - Temperature inputs’) can be
selected here.
!
Note!
Only for heat diff. applications.
Min. T-Diff. 0.0 to 99.9 Sets the minimum temperature difference. If the measured
temperature difference undershoots the set value, the heat
quantity is no longer calculated.
!
Note!
Only for water heat diff. applications.
