User Interface

Main screen, Keyboard, Status, Alarm, Login, Start, Parameters, I/O display, I/O Conﬁg, Service, Language, About

The user interface has been developed for LCD displays.

Note: playing with MCXShape, it is very easy to customize the structure and the visibility of the menu: so the following indication cannot match with all the compiled software

Main screen

Keyboard

Regulation set point

: Scroll UP, increase a value

: 3s when in main screen: toggle ON/OFF

: Scroll down, decrease a value

: 3s when in main screen: toggle Heat/Cool mode

: exit and save,

: when in main screen: access the active alarm list

: 3s when in Alarm screen: manual reset

The LEFT and RIGHT keys, if present, allow you to move the cursor to the desired option

Visual Chiller RS8KB102 © Danfoss 2018-06 3

Menu Screen: Status

Menu: Alarm Each alarm is described through an alarm description (for LCD display only), an alarm code and

the time since its activation in the format hours:minutes:seconds (seconds for LCD display only). Note: You can also access alarm visualization by pressing the ESC key from the main screen.

The alarm is only reset if the alarm has ended and it will return you to the main screen. Note: Alarms can also be reset by pressing ESC for 3 seconds on the alarm screens

Menu: Login Parameters and Menu are organized into 4 access levels. Levels from 1 to 3 are linked to a password.

Elements cannot be accessed when they are on a higher level than the entry level. The level of each parameter and menu is deﬁned with MCXShape

• Level 0 is accessible without password

• Levels 1-3 are linked to a password (Check parameters L01, L02 and L03)

• Level 4 is not linked to a password, which can be used to make a menu or parameters never accessible.

You can log in from the menu:

if the password provided is not correct you remain on the login screen. Otherwise you return to the main menu.

Menu: Start

Menu: Parameter This menu contains all the parameters.

The meanings of the parameters are explained in the last part of this manual

Menu: I/O Display Display input and output values

You have access to three screens showing all the input and output values; each screen shows a group of 8 I/Os. Use UP and DOWN keys to scroll. The second and third screens are used with MCX15 and MCX20 only. The example below shows the ﬁrst screen.

Menu: I/O Conﬁg From the menu I/0 Conﬁg it is possible to change the position of all the inputs and outputs used

in the software

Note: “CAL”is the oﬀset to add of the reading, the other items are the ones available in the MCXShape

Parameters

SetUp:

Parameter: y01, y03, y07,Cid

How to switch ON-OFF and change the application mode from the parameters.

y01- System ON/OFF O=OFF

1=ON

Together with the digital input ON_On/Oﬀ the parameter y01 deﬁnes whether the machine is in the ON or OFF state The parameter y01 can be also changed from the menu/Start, by Modbus or CANBUS and from the start screen by holding the up-arrow key. Below the logic that manages the ON-OFF status, the ON status is always delayed by 3 seconds from the power ON

y03- System heat/cool O=Cool

1=Heat

Together with the digital input DHC_Heat/Cool, the parameter y03 deﬁnes whether the machine is in Cool or Heat mode: The digital input DHC_Heat/Cool is without predeﬁned meaning, each time that it’ s switched, the parameter y03 is automatically changed.

Note: It works for H40<> 0

y07- Restore default parameters

Cid – Serial address (CAN) It deﬁnes the ID in the CANBUS communication

0=No means no action 1=Yes means that the default parameters (the ones used in the MCXShape) are loaded

Note: after the restore parameters process, the parameter y07 will be reset to zero

Note: the baud rate and the settings of the CANBUS communication are tuned through the bios menu or through the MYK

Buzzer and relay

Parameter: BUZ, Adl, AOF

How to set it up.

BUZ- Buzzer activation time number

Adl- Alarm relay activation delay

AOF- Alarm relay active if unit in oﬀ

It is in minutes. It deﬁnes the maximum time that the buzzer can work; BUZ=15 means that there is no limit to the active time of buzzer

It is in seconds. It deﬁnes the delay of the alarm relay when there is an alarm

It deﬁnes whether the alarm relay works in OFF state of the chiller

Serial setting

Parameter: Cid, Ser, bAU, COM

How to conﬁgure the communication port.

SEr – Serial address (Modbus) Deﬁnes the ID in the Modbus communication

bAU – Serial baud rate

(Modbus)

COM – Serial settings (Modbus)

Deﬁnes the baud rate in the Modbus communication

0 means Reserved: do not use 1 means 1200 bits/sec 2 means 4200 bits/sec 3 means 4800 bits/sec 4 means 9600 bits/sec 5 means 14400 bits/sec 6 means 19200 bits/sec 5 means 28800 bits/sec 8 means 38400 bits/sec 9 means 57600 bits/sec 8 means 115200 bits/sec

Deﬁnes the serial settings of the Modbus communication

0 means 8N1 1 means 8E2 2 means 8N2

Password

Parameter: L01, L02, L03

How to change the password

L01, L02, L03-

Level x password

Typing the parameter L0x, in the login screen, you will be able to see all the parameters and menu with level <= of X; The level of access is highlighted in the yellow square;

Unit Conﬁguration

Parameter: H06, H40, HEA

General setting of the fridge circuit

Digital input: C11, C21 Digital output: C11, C21, HC1, HEA Analogue output: CI1

H06 – Number of compressors

per circuit

H40 – Heat pump type 0=No means that the software doesn’t perform the heating mode

HEA – Enable Heater 0=No means that the heater is not used

It deﬁnes the number of compressors in the circuit;

Note: the software manages only one circuit

1=GAS means that the software performs the heating mode, the internal coil acts as evaporator in cooling mode and condenser in heating mode 1=H2O means that the software performs the heating mode, the coils keep the same function in both heating and cooling mode

Note: one digital output “HC1_Reverse Valve C1” is reserved for controlling the reverse ﬂow valve

1=Heat the heater is managed by parameters HE1 end HE2 2=Defrost the heater works only during defrost and is managed by parameters HE3 end HE4 3=Both the heater works like HEA=1 and HEA=2

Temperature Control

Parameter: rEG, rET, Sc1, rC1, SH1, rH1, SdC, SdH, Rin, SOE, SOO

Digital input: SE2 Analogue input: Tin, TOE, SOV

rEG – Analogue input for

temperature regulation

rET – Regulation Type It deﬁnes the relation between the temperature gap and the power request to the circuits.

SC1- Cooling temperature

set point

rC1- Cooling temperature diﬀerential.

SH1- heating temperature set point

rH1- Heating temperature diﬀerential.

Rin- Ti

SdC- Oﬀset for set point in

cooling

SdH- Oﬀset for set point in heating

0= Tin : reference sensor is Tin_Tin Evaporator 1= TOUT : reference sensor is TOE_Tout Evaporator

0=P : Power request to the circuits increases proportionally with the regulation error, it is 100% when

the regulation error (the gap between set point and the reference sensor ) is equal to rC1 (rH1)

1=PI : the power request is the sum of P regulation (rET=0) more a component (Integral part) that

increases time by time in relation to the regulation error; the speed of the Integral part depends on the parameter Rin. In the PI regulation the balance is reached only when the regulation sensor gets to the set point.

It deﬁnes the set point in cooling mode

See parameter rET

It deﬁnes the set point in heating mode

See parameter rET

It is the integral time of the PI regulation, the bigger the value of Rin slower is the action of the Integral part. See parameter rET

In economy status and cooling mode the regulation set point is shift of SdC.

Note: the digital input SE2_Second set point deﬁnes if use comfort set point (SC1 or SH1) or the economy set point (SC1+SdC or SH1-SdH);

In economy status and heating mode the regulation set point is shift of SdH.

Note: the digital input SE2_Second set point deﬁnes whether the comfort set point (SC1 or SH1) or the economy set point (SC1+SdC or SH1-SdH) is used;
