5.9.2 HRC Mode Swing Protection
In order to prevent the HRC mode being frequently activated / deactivated in the event of any cycling of the
HRC input signal (digital input 21, terminals 90/91), the HRC mode is disabled after ending the HRC mode for a
configurable time using the parameter
Off Time HRC (menu 3-2-2-3). An error message is also output in the
case of cycling HRC input signal.
5.9.3 Setpoint Calculation in HRC Mode
The following setpoints for the regulation can have different behaviour in HRC mode:
HP setpoint (HP valve regulation)
t
G
setpoint (gas cooler outlet temperature regulation)
t
0
setpoint (low pressure regulation)
HP setpoint
In controlled operation, the HP setpoint is calculated depending on the gas cooler outlet temperature.
In HRC mode, the HP setpoint can
be specified as a fixed value using the parameter HP-Max.HRC (menu 3-2-2-3),
be shifted within the limits defined by the two parameters HP-Min.HRC and HP-Max.HRC in menu 3-2-2-3
when setpoint shift (parameter Setp.shift. , menu 3-2-2-3 set to Y) via an external signal is activated, or
can be shifted via CAN bus within the limits defined by the two parameters HP-Min.HRC and HP-Max.HRC
in menu 3-2-2-3.
