Configuration of light function
(If night blind selected, it will be synchronised with the light function)
1) Light is controlled via day/night status
2) Light is controlled via data communication and "Light remote o39"
3) Light is controlled by door contact, as defined via a DI input where the setting is
selected as either 2 or 3. 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 controlled with local DI switch and a central signal from either data commu-
nication or a 230 V signal on DI7. Both must be on before the light is turned on.
6) Like "5", but manual control of the night blind will also activate the light, which
means the light will switch on when the night blind is up.
Activation of light relay
Here the relay can be activated, but only if a setting of 2, 5 or 6 has been defined in
o38.
Rail heat during day operation
The ON period is set as a percentage of the time
Rail heat during night operation
The ON period is set as a percentage of the time
Rail heat cycle
The period of time for the aggregate ON time + OFF time is set in minutes
Case cleaning
The status of the function can be followed here or the function can be started
manually.
0 = Normal operation (no cleaning)
1 = Cleaning with fans operating. All other outputs are Off.
2 = Cleaning with stopped fans. All outputs are Off.
If the function is controlled by a signal at a DI-input, the relevant status can be seen
here in the menu.
Selection of application
The controller can be defined in various ways. Here you set which of the
8 applications is required. On page 13 to 16 you can see a survey of applications.
This menu can only be set when regulation is stopped, i.e. "r12" is set to 0.
Access code 2 (Access to adjustments)
There is access to adjustments of values, but not to configuration settings. If the
settings in the controller are to be protected with an access code you can set a
numerical value between 0 and 100. If not, you can cancel the function with setting 0.
If the function is used, access code 1 (o05) must also be used.
Save as factory setting
With this setting you save the controller's actual settings as a new basic setting
(the earlier factory settings are overwritten).
Digital input signal - DI3 Switch signal
The controller has a digital input 3 which can be used for one of the following
functions:
Off: The input is not used.
1) Status display of the switch function
2) Door function. When the input is open it signals that the door is open. The refrig-
eration and the fans are stopped and light turn on. When the time setting in "A04"
has passed, an alarm will be issued. The cooling is restarted when the time in o89
has passed.
3) Door alarm. When the input is open it signals that the door is open. When the time
setting in "A04" is passed an alarm will be given.
4) Defrost. The function is started with a pulse signal. (see also o37)
5) Main switch. Regulation is carried out when the input is closed, and regulation is
stopped when the input is open.
6) Night operation. When the input closed, there will be regulation for night
operation.
7) Thermostat band changeover. Switch to thermostat 2 (r21) when the input
is closed.
8) Not used.
9) Not used.
10) Case cleaning. The function is started with a pulse signal. See also description
on page 5.
11) Forced refrigeration at hotgas defrost when the input is closed.
12) Night cover. Pulse signal activates night blind
13) Not used
14) Forced closing when input is interrupted.
15) Appliance shutdown when input is closed.
16) Light. DO3 pulls when the input is closed.
17) Extra light. DO4 pulls when the input is closed.
18) Cancel defrost cycle. All defrost cycles are cancelled when the input is closed.
19) Override light (pulse signal)
