DIGITAL INPUTS

effect caused by activation of microport input; see also i4
0 = no effect
1 = the cabinet light will be switched on (only if u1 = 0, until the input is deactivated)
2 = the evaporator fan will be switched off (for up to the length of time set by i3 or until
the input is deactivated)
3 = the compressor and evaporator fan will be switched off (for up to the length of time
set by i3 or until the input is deactivated) (18)
4 = the evaporator fan will be switched off (for up to the length of time set by i3 or until
the input is deactivated) and the cabinet light will be switched on (only if u1 = 0, untilthe
input is deactivated)
5 = the compressor and evaporator fan will be switched off (for up to the length of time
set by i3 or until the input is deactivated) and the cabinet light will be switched on (onlyif
u1 = 0, until the input is deactivated) (18)
microport input contact type
0 = NA (input active with contact closed)
1 = NC (input active with contact open)
microport input alarm signal delay
-1 = the alarm will not be reported
maximum duration of the effect caused by activation of the microport input on the
compressor and on the evaporator fan
-1 = the effect will last until the input will be disabled
recording of microport input alarm (19) 1 = YES
effect caused by activation of the multifunction input (only if P4 = 3)
0 = no effect
1 = DEFROST SYNCHRONISATION - after the period of time set by d5 defrosting will be
activated
2 = ACTIVATION OF ENERGY SAVING FUNCTION - the Energy Saving function will be
activated (until the input is deactivated); see also r4
3 = CLOSURE OF THE AWNING - the cabinet light will be turned off (only if u1 = 0 and
only if switched on manually) and the Energy Saving function will be activated (untilthe
input is deactivated); see also r4
4 = ALARM ACTIVATION - after the amount of time set by i7 the display will flash the
code "iA" and the buzzer will be activated (until the input is deactivated)
5 = TRIPPING THE PRESSURE SWITCH - the compressor will be switched off, the
display will flash the code "iA" and the buzzer will be activated (until the input is
deactivated);see also i7, i8 and i9
6 = TURNING ON THE AUXILIARY OUTPUT - the auxiliary output will be turned on (only
if u1 = 2, until the input is deactivated)
7 = SWITCHING OFF THE DEVICE - the device will switch to stand-by mode (until the
input is deactivated)
type of multifunction input contact (only if P4 = 3)
0 = NA (input active with contact closed)
1 = NC (input active with contact open)
if i5 = 4, delayed multifunction input alarm notification (only if P4 = 3)
if i5 = 5, delayed multifunction input deactivation compressor delay (only if P4=3) (20)
number of multifunction input alarms such as to cause device block alarm (only if P4 = 3
and i5 = 5) 0 = no alarm
time that must elapse without multifunction input alarms so that the alarm counter is
zeroed (only if P4 = 3 and i5 = 5)

DIGITAL OUTPUTS

service controlled by the fourth output (21)
0 = CABINET LIGHT - in this case, the important factors are: the key
i5 and u2
1 = DEMISTING HEATER - in this case, the important factors are: the key
parameter u6
2 = AUXILIARY OUTPUT - in this case, the important factors are: the key
parameters i5 and u2
3 = COMPRESSOR 2 - in this case, the important factor is parameter C9
4 = ALARM OUTPUT - the output is activated during an alarm and during an error; in this
case the important factors are parameters u3 and u4
5 = DOOR ELEMENT - in this case the important factor is parameter u5
6 = EVAPORATOR VALVE - in this case the important factors are parameters u7 and u8
7 = DEFROST SYNCHRONISATION - the output works in parallel with the defrost
output; in this case the important parameter is factor i5 (22) (23) enabling cabinet light or
auxiliary
enables manual switching on/off of the cabinet light or auxiliary output while in stand-by mode
(only if u1 = 0 or 2) (24) 1 = YES
alarm output polarity (only if u1 = 4)
0 = disabled during normal operation (the contact between terminals 6 and 7 will be
open) and activated during an alarm and during an error (the contact between terminals6
and 7 will be closed)
1 = activated during normal operation (the contact between terminals 6 and 7 will be
closed) and disabled during an alarm and during an error (the contact between
terminals6 and 7 will be open)
enable alarm output deactivation with muting of buzzer (only if u1 = 4) 1 = YES
cabinet temperature above which the door element is switched off (only if u1=5) (7)
demisting heating duration (only if u1 = 1)
cabinet temperature below which the evaporator valve is deactivated (in relation to the
operational setpoint, i.e. the "operational setpoint + u7") (only if u1 = 6) (7)
evaporator valve contact type (only if u1 = 6)
0 = NA (valve active with contact closed)
1 = NC (valve active with contact open)
