Functional Description with Process Diagrams
5.4.3.2 I Term
The firing rate controller can use an actual current value (mA), the boiler temperature (°C, °F)
or the steam pressure (bar, psi) as the actual value for control. P 61 defines the unit of the
actual value.
For steam pressure, P 62 and P 63 are also required.
5.4.3.3 Constant Controller
If the firing rate controller is used as a constant control, its setpoint is obtained from the pa-
rameters
•
P 49 for setpoint 1
•
P 51 for setpoint 2
P no.

61
Selection of the actual value input and the unit for indication (0-Digit; 1-°C; 2-bar; 3-mA; 4-
°F; 5-psi)
V1.0.0.0
Selection of the unit in which the input for actual value is to be indicated
0 = Digit

62
Pressure input: Scaling minimum
V1.0.0.0
Pressure at 4 mA input current in 0,1 units (bar, psi).
Input of the lower limit of the display range, which corresponds to 4 mA at the input, if the
input is configured as pressure input.
This parameter can only be active if P 61 = 2
Example: Value = 100, is equal to a minimum pressure of 10,0 bar/psi

63
Scaling maximum
V1.0.0.0
Pressure at 20 mA input current in 0,1 units (bar, psi).
Input of the upper limit of the display range, which corresponds to 20 mA at the input, if the
input is configured as pressure input. This parameter can only be active if P 61 = 2
Example: Value= 500, is equal to a maximum pressure of 50,0 bar/psi
