AK-PC 781 Version 4.1x

Cut-in compressor capacity in % (of total capacity)

Reference for compressor capacity (deviations may be due to time delays)

Suction pressure in °C. (Measured with the pressure transmitter)

Actual suction gas temperature

Actual temperature for control sensor (Pc or S7)

Actual reference temp. for condenser capacity

(incl. external contributions, if any)

Cut-in condenser capacity in % (of total capacity)

Reference for condenser capacity

Condensing pressure (measured with the pressure transmitter)

Condensing pressure in °C. (measured with the pressure transmitter)

Actual gas cooler operation:

0=Off. 1=Standby. 2=Max COP operation. 3=Heat recovery. 4=Extra capacity.

5=Manual control.

Actual gas cooler pressure

Actual reference for gas cooler pressure

Actual discharge gas temperature

Actual temperature at outlet from the gas cooler

Readout limit value for max condenser pressure

Actual media temperature measured at S7 sensor

(Only used if S7 is selected as control sensor)

Outdoor temperature in °C measured with Sc3 temperature sensor

Defined number of fans

Status of analogue output signal "AO" for variable speed drive (in percent of

full scale f.ex. 0 -10 V d.c.)

Status of safety monitoring input for Variable Speed Drive

ON: Alarm on VSD A safety monitoring input

OFF: No alarm on VSD A safety monitoring input

Main switch:

0: MAN (The condenser capacity will be controlled manually)

1: OFF (The capacity control will be stopped)

2: AUTO (The capacity is controlled by the PI controller)

Manual setting of condenser capacity

The value is in % of total capacity controlled by the controller

0: Set point

1: Floating

Setting of required discharge pressure in °C

Dimensioning mean temperature differential between air- and condensing

temperature at full load for the condenser in question (Typical 8 – 15K).

Controller has been powered up (power supply re-connected)

Capacity control has been stopped ("Main switch" = OFF or

"Control mode" = OFF)

Capacity is controlled manually ("Control mode" = MAN)

Capacity control is in alarm condition (f.ex. Pc Max or Sd Max)

Capacity control is waiting for elapse of "Restart time"

Capacity control is ready to start

flow can not start)

Monitoring function adapts to the condenser in question

Monitoring function is switched OFF

Air flow is OK

The amount of dirt decreases the performance of the condenser,

clean when possible

The amount of dirt leads to considerable air flow problems, clean

as soon as possible

The amount of dirt might lead to high pressure problems, clean

now

ON:

Regulation

OFF: Controller stopped

Reference = "PcA setpoint °C"

Reference is changed as a function of the outdoor temperature

measured by the "Sc3 air on" sensor, the set "Dimensioning tm K"

and the actual compressor load.
