operates as a step controller with the steps 2 to n-1.
The following maximum numbers of stages can be disabled or enabled:
Fan Control via Modbus : 11 fan stages
Fan control via relays, requiring one SIOX extension module: 3 fan stages
The stage
No. cond. 1
cannot be programmed for operation by power supply. It is not displayed on the
operator terminal, the store computer and in the LDSWin PC software.
5.6.9 Setpoint Calculation tG
The setpoint for the gas cooler temperature t
G
depending on the outdoor temperature is calculated according to
a programmable characteristic curve. The outdoor temperature is provided either by a Pt1000 sensor that is
connected directly to the input of the pack controller (terminals 1/2/3/4) or via the CAN bus from another pack
controller in the system.

5.6.9.1 Setpoint Increase tG
With the controller, it is possible to enter a temperature offset
t
G
-Offset N
(menu 3-2-2-2) which is added to the
setpoint temperature t
G_Soll
when setpoint switching is active.
5.6.10 Input Signal for Frequency Converter
The t
G
setpoint is calculated as described in chapter
Setpoint calculation for gas cooler outlet temperature
.
A setpoint for the fan speed is also calculated.
The calculation of this setpoint for the fan speed is made in the same way as all continuous fan control modes:
