Miscellaneous
Delay of output signals after start-up
Input signal on DI1. Function:
0=not used. 1=status on DI1. 2=door function with alarm when open. 3=door alarm
when open. 4=defrost start (pulse-pressure). 5=ext.main switch. 6=night operation
7=change reference (activate r40). 8=alarm function when closed. 9=alarm function
when open. 10=case cleaning (pulse pressure). 11=Inject off when open.
Network address
On/Off switch (Service Pin message)
Access code 1 (all settings)
Used sensor type (Pt /PTC/NTC)
Display step = 0.5 (normal 0.1 at Pt sensor)
Max hold time after coordinated defrost
Configuration of light function (relay 4)
1=ON during day operation. 2=ON / OFF via data communication. 3=ON follows the DI-
function, when DI is selected to door function or to door alarm
Activation of light relay (only if o38=2)
Case cleaning. 0=no case cleaning. 1=Fans only. 2=All output Off.
Access code 2 (partly access)
Save the controllers present settings to the programming key. Select your own number.
Load a set of settings from the programming key (previously saved via o65 function)
Replace the controllers factory settings with the present settings
Select application for S5 sensor (0=defrost sensor, 1= product sensor, 2=condenser sen-
sor with alarm)
Select application for relay 4: 1=defrost/light, 2= alarm
Service
Temperature measured with S5 sensor
Status on DI1 input. on/1=closed
Status on night operation (on or off ) 1=closed
Read the present regulation reference
Status on relay for cooling (Can be controlled manually, but only when r12=-1)
Status on relay for fans (Can be controlled manually, but only when r12=-1)
Status on relay for defrost. (Can be controlled manually, but only when r12=-1)
Temperature measured with Sair sensor
Status on relay 4 (alarm, defrost, light).(Can be controlled manually, but only when
r12=-1)
Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep upper and lower button depressed at the same time as you recon nect the supply voltage
