User levels
To avoid parameter changing by unauthorized persons, 3 different user levels
are available:
1
.
Customer Level
In this level setpoints can be changed, but it is impossible to change
the configuration of the unit.
2
.
Service Level
(call-up with code 2)
Here the service contractor finds parameters and information for
start-up and service.
3
.
Configuration Level
(call-up with code 3)
Here you can change all parameters, even the fundamental functions
to assign inputs and outputs.
In the single levels only the accessable parameters will be displayed (marked
by 'Level 1,2,3' on the parameter pages).
Using the Access Protection
The parameter „
operator layer
“ on Mode Page is factory set to „no“. Thus
you will see all parameters, the same as if the 'Configuration-Level' would
be active.
After start-up, you protect the controller unit effectively by changing parameter
„
operator layer
“ (mode page) to „yes“. If you don’t touch any key for at least 3
minutes or if you switch off power for a moment, the protection will be activated.
Thus only the parameters of the
Customer Level
can be displayed.
All other parameters are hidden now and can be accessed only by knowing
the code.
To change from Customer Level to Service- or Configuration Level do as
follows:
• Select 'basic Display',
• Press key "Prog",
• Enter code for desired level.
Change parameters
To change a parameter in the single user levels, the unit frequently expects
an additional 'Identification Code'. (see right column).
As long as parameter "
operator layer
" is not set to "no", the unit changes to
the
Customer Level
if no key is pressed for about 3 minutes.
Parameter Protection / Identificaton
Almost all parameters, except the temperature setpoints, are protected
by a simple password.
If you have to change a parameter and you have pressed the "RET"-key,
this display appears:
The controller expects now the input of a code-no. This code-no. (Code
1) is related from the actual time of the day as the sum of the
hour (0 to 23) plus 10
Example:
At 9:35 a.m. the code is 9 + 10 = 19.
At 21:35 (9:35 p.m.) the code would be 21 + 10 = 31.
If you have pressed no key for about 3 minutes, the parameters are
locked again automatically.

Codes for Customer Levels
Code 2: ......Fixed Code: -
88
- (calls up Service Level)
Code 3: .....
Month + Hour + 20
(calls up Configuration Level)
Example: (Note: Real-time clock must be set to the
right time and date before.)
You want to change a parameter at a day in june at 9:35
in the morning. Identification Code = 6 + 9 +20 =
35
.
Unit Text
In the mode page you have the possibility to define a specific text (max.
16 characters) for the controller, e.g. „meat-store“. This name will be
indicated on the screen of the VPR compound controller or on a PC with
matching software.
Change text:
• select parameter „unit text“ (mode page)
• „
RET
“ Start programming, the first character position flashes
(eventually, you must enter the access code before)
• "
" change character
• „
RET
“ the next character flashes
• "
" change character
....and so on
• press „
RET
“ to confirm the last character.
Changing the text can also be made by the software 'COOLVision' or 'CV-
Scheduler'.
Display Language
The language used on display can be changed by "
Sprache/Language
"
(mode page) to german, english, french or dutch.
