Doku-Version 2.05 - Firmware 2.10 - 15. September 2017

4.4.5

Monitoring the digital inputs

The four digital inputs can each be parameterised for the following monitoring tasks:

S

Load shedding

S

Setpoint toggle

S

External alarm

S

HRC (Heat recovery mode)

S

Safety loop

‐ Im zugeordneten Regelkreis werden alle Schaltstufen sofort abgeschaltet

‐ Es wird eine Meldung abgesetzt (verfügt die Steuerung über einen CAN-Bus-Schnittstelle,

so kann dieser Meldung ein frei editierbaren Text zugewiesen werden.

‐ Die Verbraucherfreigabe der zugehörigen Kühlstellenregler wird entzogen, es sei denn,

der Niderdruck ist zu tief.

S

Fast unload / External OFF

‐ When the input is activated the following occurs:

‐ Fans and compressors are turned off in quick succession (2 seconds unload time).

‐ The consumer enable of the corresponding case controller UA 300 is revoked,

unless the low pressure is too low.

‐ The fault report

Fast unload CL1/CL2

is sent.

‐ The pack controller is shown in grey in the store view of the PC software LDSWin.

When a digital input

Fast unload extern OFF

is used for a safety-critical application,

additional measures for the purpose of monitoring must be undertaken.

4.5

High-pressure control / Condenser control

The refrigerant is chilled in the condenser by removing heat with the condenser fans. A physical relationship ex
ists between high pressure and refrigerant temperature, meaning that high pressure or condensing temperature
(condenser control) can be controlled with the condenser fans. The VS 300 Pack Controller provides three dif
ferent methods for these control functions:

S

High-pressure control

‐ Step controller:

Control by loading and unloading condenser capacity stages

‐ Speed controller:

Control by speed adjuster. High pressure is controlled by an analog signal
that sets the required speed on the speed adjuster.

‐ Combined controller:

Control by combination of speed adjuster and additional loading and
unloading of condenser capacity stages.

High-pressure control includes additional monitoring functions:

S

Base load rotation

S

Fan protection

With the VS 300 the actual value is measured by a pressure transducer with continuous current output
(4-20 mA). The control type can be defined using the integral user interface or an external terminal (AL 300 Opera
tor Terminal and CI 3000 Store Computer).
