11.1.7 Individual allocation of priorities
It is possible in the case controller to allocate an individual priority for most alarms (parameter Kühlstellenregler
prio set to NO, menu 6-5). This enables the targeted addressing of alarm destinations and the adjustment of
alarm signalling to individual requirements.
The priority on the controller side is used if the parameter Kühlstellenregler prio is set to YES (menu 6-5). It is
also always used for the alarm signalling in the event of failure of the control by the system centre / store
computer.
The value range for the priorities is extended to 0..99 so that up to 100 alarm destinations can be differentiated.
This priority range is divided into 10 alarm groups (decades).
The 1 and 2 priorities (1,11,21,...91 and 2,12,22,...92) are reserved for high priority alarms that affect the
alarmrelays“PRIO1”and“PRIO2”aswellastheLEDs“PRIO1”and“PRIO2”onthefrontofthestore
computer.
The highest priority number in each group (9,19,29,...99) is reserved for low priority alarms which should
only generate local alarm signalling (e.g. open cold room door).
All other priority numbers are intended for low priority alarms.
The lowest priority number in each group (0,10,20,..90) is reserved for messages that are only recorded in
the message list.
Ifthepriorityissetto"–",nomessageisgenerated.
This division into alarm groups (decades) facilitates maintenance group oriented alarm management.
The respective alarms (exception: refrigeration point priority and setpoint adjustment) can also be set to the
value "--" and thus be completely removed from the alarm signalling.
If the parameter Kühlstellen-Priorität is sent to the value NO (menu 6-5), the allocation of individual priorities is
enabled. For the setting YES, the alarm priorities are allocated according to the previous schema with the value
of the refrigeration point priority. This simplifies the configuration for standard applications.
Thar following assignments arise from the allocation of the global priority:
Alarms with global priority Alarms with the priority 0
Low Temperature
High Temperature
Sensor Fault
Cold room door open (only for the room controllers)
No defrost (all except UR 141 TK)
First start
EEPROM Fault
RTC Fault
Flash Fault
No defrost (only UR 141 TK)
Time defrost termination
Power failure
Manual shutdown
Setpoint change
Refrigeration point disabled
Battery voltage
External alarm (CO2 alarm)
Special feature: for the UR 141 TK, the priority for the No Defrostalarmsignallingissettozero,whilethis
valuecorrespondstotheglobalcontrollerpriorityforallothercontrollertypes.
The alarm priorities --, 0..2 correspond to the remote alarm messaging concept of older store computer
versions with firmware versions <5.0. If priorities from 3..99 are configured in the controller, the store
computer must be updated to a firmware version of 5.0 or higher. Further information is provided in the
store computer operating manual.
