8.1 Configuration parameters (continued)
Parameters Minimum Maximum U.M. dEF. Temperature Inputs (continued)
A0 0 2 — 0
measured input used for the low temperature alarm
0 = cabinet temperature
1 = evaporator temperature
A1 -99.0 99.0 °C/°F -10.0 temperature below which the low temperature alarm is activated; also look at A0 and A2
A2 0 2 — 1
kind of lower temperature alarm
0 = alarm not enabled
1 = relative to the working setpoint (or “working setpoint - A1”; consider A1 without sign)
2 = absolute (or A1)
A4 -99.0 99.0 °C/°F 10.0 temperature above which the high temperature alarm is activated; also look at A3 and A5
A5 0 2 — 1
kind of upper temperature alarm
0 = alarm not enabled
1 = relative to the working setpoint (or “working se A4”; consider A4 without sign)
2 = absolute (or A4)
A6 0 240 min 120 high temperature alarm delay since you turn on the controller (only if A3 = 0)
A7 0 240 min 15 temperature alarm delay
A8 0 240 min 15
high temperature alarm delay since the end of the after dripping evaporator fan delay
(only if A3 = 0)
A9 0 240 min 15
high temperature alarm delay since the deactivation of the door switch input (only
PSK223 and PSK233)
Parameters Minimum Maximum U.M. dEF. Evaporator Fan
F0 0 4 — 1
evaporator fan activity during the normal operation
0 = turned off
1 = turned on
2 = according to the compressor
3 = according to F1
4 = turned off if the compressor is turned off; according to F1 if the compressor is
turned on
F1 -99.0 99.0 °C/°F -1.0
evaporator temperature above which the evaporator fan is turned off
(only if F0 = 3 or 4)
F2 0 2 — 0
evaporator fan activity during defrost and drip delay
0 = turned off
1 = turned on
2 = according to F0
F3 0 15 min 2 fan delay after evaporator drip completes
Parameters Minimum Maximum U.M. dEF. digital Inputs – Only PSK223 and PSK233
i0 0 3 — 2
kind of digital input
0 = MULTIPURPOSE INPUT - in this case look at parameters i1, i5, i7, i8 and i9
1 =
RESERVEd
2 = dOOR SWITCH INPUT - in this case look at parameters i1, i2 and i3; the
activation of the input will turn off the evaporator fan (for at most time i3 or until
the input is deactivated)
3 =
dOOR SWITCH INPUT
- in this case look at parameters i1, i2 and i3; the
activation of the input will turn off the compressor and the evaporator fan (for at
most time i3 or until the input is deactivated)
i1 0 2 — 0
digital input contact type
0 = NO (the input will be active if you close the contact)
1 = NC (the input will be active if you open the contact)
2 = input not enabled
i2 -1 120 min 30
delay before the door switch alarm is activated
-1 = no signal
i3 -1 120 min 15
maximum duration of the effect provoked by the activation of the door switch input
-1 = the effect will last as long as the input will be deactivated
i5 0 6 — 3
effect provoked by the activation of the multipurpose input
0 = no effect
1 =
SYNCHRONIZING THE dEFROSTS
- after time d5, the defrost will be activated
2 = ACTIVATING ENERGY SAVING - Energy Saving function will be activated (until
the input is deactivated); also look at r4
3 = ACTIVATING THE EXTERNAL ALARM - after time i7, the display will flash the
code
“iA”
and the buzzer will be activated (until the input is deactivated)
4 = ACTIVATING THE COMPRESSOR LOCKOUT - the compressor will be turned
off, the display will flash the code
“iA”
and the buzzer will be activated (until the
input is deactivated); also look at i7, i8 and i9
5 =
TURNING OFF THE CONTROLLER
- the controller will be turned off via software
(until the input is deactivated); also look at C0, d4 and A6
6 =
ACTIVATE COOLING
(only PSK223 and PSK233) - the compressor will be turned
on (until the input is deactivated); in this case parameters C4 and C5 are not
meaningful
