3 Application of VS 300
The VS 300 Pack Controller is designed for controlling small to medium refrigeration compressor packs and
condensers. It contains its own user interface with 4-digit 7-segment LED display and is suitable for stand-alone
use. When expanded by an optional CAN bus module, it can be fully integrated into the LDSWin remote moni­
toring system. Additionally, it can be combined with an optional alarm module containing two alarm relays (Prior­
ity 1 and Priority 2).
For the compressor pack and condenser the VS 300 provides the following functions:
S
Control and regulation
S
Fault reporting
S
Fault archiving
S
Monitoring
S
Archiving
These functions are as follows:
Pressure control with two freely configurable control loops for one or two independent refrigerant circuits (tem­
perature/pressure ranges:
NT - low-pressure normal-temperature refrigeration, LT - low-pressure low-tempera­
ture refrigeration and HP - high pressure) Depending on the expansion stage, the maximum number of relay/
control stages is as follows:
‐ 4 relay/control stages (basic configuration)
‐ 8 relay/control stages (first expansion stage)
‐ 12 relay/control stages (second expansion stage)
The relay/control stages can be allocated to one control loop or split between the two control loops. Capacity-
controlled compressors with up to three capacity stages are supported.
