AK-CC55 Compact
Function
Description
Rail heat control
The rail heat can be controlled in several ways: 0: Rail-
mode
heat is running all the time 1: Pulse control is used
with a timer function following the day/night opera-
tion 2: Pulse control is used with a dew point function.
This function requires that a signal is received about
the dew point value. The value is measured by a sys-
tem manager and sent to the controller via the data
communication.
Rail heat ON cycle
Railheat power during day time. The ON period is set
day
as a percentage of the period
Rail heat ON cycle
Railheat power during night time. The ON period is
night
set as a percentage of the period time
Rail heat period
Periodtime for pulsing of railheat
time
Rail heat PWM - Peri-
Period time for the pulse width modulation
od time
Rail heat min ON cy-
Lowest permitted rail heat power. When the meas-
cle
ured dew point is below the defined minimum limit
the rail heat will run with the set minimum power
Dewpoint min limit
If the measuered dew point is below the set value the
rail heat is running at minimum heat
Dewpoint max limit If the measured dew point is above the set value the
rail heat is maximum

Function
Description
Control state A
Readout of the actual control state of the controller
Night condition
Status at the day-/night operation (night operation:
on/off)
Light
Actual status of output function
Blinds
Actual status of output function
Light control mode
Configuration of light function1: Light is controlled
via day/night status 2: Light is controlled via data
communication and master control parameter "MC
Light signal" 3: Light is controlled by door contact on
DI input. When the door is opened the relay will cut
in. When the door is closed again there will be a time
delay of two minutes before the light is switched off.
4: As "2" but if there are any 15-minute network errors,
the light will switch on and the night blind will open.
5: Light is controlled via DI input signal
Light at Main switch
Define how light and blinds are to be controlled at
OFF
Main switch OFF 0: Light is switched off and night
blinds are open when the main switch is off 1: Light
and night blinds are independent of main switch.
Blinds max open
Time delay from when blinds have been opened
time
manually until they close again
Case cleaning mode The status of the function can be followed here or the
function can be started manually.0 = Normal opera-
tion (no cleaning) 1 = Only fans are running to defrost
the evaporator. All other outputs are Off. 2 = Cleaning
with stopped fans. All outputs are Off. If the function
is controlled by a digital input signal, the relevant sta-
tus can be seen here in the menu.
