Input signal on DI2. Function:

(0=not used. 1=status on DI2. 2=door function with alarm

when open. 3=door alarm when open. 4=defrost start

(pulse-signal). 5=ext. main switch 6=night operation

7=thermostat band changeover (activate r21). 8=alarm

function when closed. 9=alarm function when open.

10=case cleaning (pulse signal). 11=forced cooling at hot

gas defrost.). 12=night cover, 13=coordinated defrost)

Configuration of light function

: 1=Light follows day /night

operation, 2=Light control via data communication

via 'o39' , 3=Light control with a DI-input, 4=As "2", but

light switch on and night cover will open if the network

cut out for more than 15 minutes.

Activation of light relay (only if o38=2)

Rail heat On time during day operations

Rail heat On time during night operations

Rail heat period time (On time + Off time)

Case cleaning. 0=no case cleaning. 1=Fans only. 2=All

output Off.

Input signal on DI3. Function: (high voltage input)

(0=not used. 1=status on DI2. 2=door function with alarm

when open. 3=door alarm when open. 4=defrost start

(pulse-signal). 5=ext. main switch 6=night operation,

thermostat band changeover (activate r21)

9=Not used.

10=case cleaning (pulse signal). 11=forced

12=night cover. 13=Not used.

cooling at hot gas defrost,

14=Refrigeration stopped (forced closing))

Rail heat control

0=not used, 1=pulse control with timer function (o41

and o42), 2=pulse control with dew point function

Dew point value where the rail heat is minimum

Dew point value where the rail heat is 100% on

Lowest permitted rail heat effect in %

Time delay from "open door" refrigeration is started

Fan operation on stopped refrigeration (forced closing):

no/0=Fan Off, yes/1=Fan On

Definition of readings on lower button:

1=defrost stop temperature, 2=S6 temperature,

3=S5_B temperature

Display of temperature

1= u56 Air temperature

2= u36 product temperature

Light and night blinds defined

0: Light is switch off and night blind is open when the

main switch is off

1: Light and night blind is independent of main switch

Configuration of alarm relay

The alarm relay will be activated upon an alarm signal

from the following groups:

1 - High temperature alarms

2 - Low temperature alarms

4 - Sensor error

8 - Digital input enabled for alarm

16 - Defrosting alarms

32 - Miscellaneous

64 - Injection alarms

The groups that are to activate the alarm relay must be

set by using a numerical value which is the sum of the

groups that must be activated.

(E.g.: a value of 5 will activate all high temperature

alarms and all sensor error.
