5.13 Setpoint switching
It is possible to set a second (alternative) setpoint set of parameters, for example for day / night operation, for
the low pressure regulation. The setpoint switching can be activated using the internal week timer (parameter
"
Setpoint toggle ", menu 4) or using a digital input (terminals 88/89) of the controller. The polarity of the input
signal can be set using the parameter " signal setvalue ", see menu 3-1 (set to "High-active" at the factory ").
When setpoint toggle is activated, the following parameters in the controller are changed over:
• Temperature setpoints
• Neutral zone
• Control constant
• Switching times
• Humidity shift
• Gas cooler control maximum speed
5.14 Ambient data for the setpoint switching
The factors used for the setpoint switching (menu 3-1),
• room temperature (shift of t
0,
, parameter Room temp. )
• outdoor temperature (shift of the gas cooler outlet temperature t
G
, parameter Outdoor temp. )
• humidity (shift of t
0
, parameter Humidity )
can either be provided using the sensors connected to the pack controller or received via the CAN bus from
another pack controller.
It can be set using the parameters Room temp. , Outdoor temp. and Humidity whether sensors directly
connected to the controller are present. If any of these parameters is set to NO, the additional parameter
"Node-Nr Env.dat " is shown on the operating screen. Here, as required, the CAN bus address (node number) of
the pack controller can be entered, from which the desired ambient data will be drawn, e.g. "1" for the CAN bus
address "101".
5.15 Consumer lockout
In the event of any fault of the compressor pack. the pack controller can send a consumer lockout via the CAN
bus to all associated consumers. Associated consumers are case controllers where the node address of the
pack controller has been programmed in the configuration of the controller. The consumer lockout is sent to all
associated consumers if no compressor is available. Possible causes of failure are
• Tripping of the HP limiter
• Tripping of all motor overload cut-outs
• High pressure limiter for all compressors
• Manual shutdown of all compressors
If any of the compressor manual control switches is switched to "HAND EIN", no consumer lockout is
performed.
In the case of a suction pressure fault due to too low suction pressure or tripping of the LP monitor, no
If no ambient data should be received via the CAN bus, the parameter Node-Nr Env.dat must be set to
"-".
