  • Page 28: Temperature Control By Cold-Room Air Sensor

      5.4.3 Temperature control by cold-room air sensor Controller type UR 141 TK (LT), UR 141 NK (NT) Single on-off control Cooling is controlled by temperature measured on the cold-room sensor. The cooling relay de-energizes when temperature reaches the setpoint (switch-off value) on the cold-room sensor and re-energizes with definable hysteresis.

  • Page 29: Continuous Running Monitoring

    5.4.4 Continuous running monitoring Controller type: UA 111, UA 111 D, UA 121, UA 131 DD, UA 141 only Continuous running of refrigerated cases, e.g. in aggravated ambient conditions, has negative effects especially with multidecks.  It results in icing of the evaporator and reduced air curtain cooling. Run time continuous running monitoring provides for automatic forced shutdown of cooling as a means of preventing icing.

  • Page 30: Two Temperature Zones

    5.4.7 Two temperature zones These controller types generally allow of controlling a line-up of maximum four refrigerated display cases with one temperature zone (pilot case and three add-on cases) or two temperature zones (two pilot cases each with maximum one add-on case).  The pilot cases detect the temperatures necessary for control and input control actuations to the cooling relay. Temperature sensors of the add-on cases are largely monitored or used for defrosting.

  • Page 31: Start Delay After Fan

      5.4.10 Start delay after fan Controller type: UR 141 TK (LT) only With freezer coldrooms, cooling can be set to start with a definable delay after the fan has started. This function is useful in large low temperature coldrooms to prevent temperature stratification (warm at the top cold at the bottom) in the event of longer evaporator idle times.

  • Page 32: Defrost In General

    5.5.2 Defrost in general Defrosting prevents icing of the evaporators due to normal control action. Defrosting is performed by supplementary heating of the evaporator by the off-cycle method. Refrigeration point temperature control is deactivated during defrosting. Defrosting differs for single-zone and two-zone operation.  Defrosting in single-zone operation  R1.x: Evaporator sensor (with UA 121, UA 131, UR 141 NK/TK, UA 131 DD these sensors are used for defrosting) ...

  • Page 35 External defrosting without master-slave mode: The external defrost signal must be active for the maximum duration of defrosting. Accordingly the external defrost signal assumes the internal defrost function of Safe Defrost Time. Defrosting is however terminated regardless of the defrost signal being active when defrost termination temperature is exceeded on the defrost sensors.
  • Page 36 Separate defrost start according to the two temperature zones using the internal defrost timer Usually it is sufficient if the defrost is started simultaneously for both zones. However, should an application require it, a separate defrost for each zone can be carried out. Additional parameters are available for this purpose.
  • Page 37 Waiting time (controller type UA 121, UA 131, UR 141 NK (NT), UR 141 TK (LT) only) A wait between the time cooling is stopped and the defrost heater is started can be set at the initiation of defrosting. This prevents simultaneous operation of the defrost heater while the evaporator is being pumped down.

  • Page 38: Discharge Gas Defrosting (Hot Gas Defrosting)

    5.5.3 Discharge gas defrosting (hot gas defrosting) Discharge gas defrosting involves feeding discharge gas into the evaporator and can be performed with either hot or cold gas.  The discharge gas is supplied from a point upstream of the condenser (hot gas defrosting) or from the receiver downstream of the condenser (cold gas defrosting). ...

  • Page 39: Brine Defrosting

    5.5.4 Brine defrosting Defrosting with brine may be considered a special form of discharge gas defrosting (hot gas defrosting). The brine defrosting is initiated and ended via the CAN bus by the pack controller. A special feature of brine defrosting consists in synchronized operation of the cooling relay and defrost relay, meaning that the cooling relays remain open during defrosting.

  • Page 41 The slaves, with respect to the parameter “M/S Abt Fkt” are set to “Slave”. The parameter “M/S CAN Adr.” must be set to the CAN address of the master controller, and that for all participating slave controllers. Application special case - Synchronisation of both defrost zones If the M/S CAN address on a slave is set to “—“, then a defrost via internal and external defrost timers is  possible. This enables both zones of the respective controller to be synchronised so that they return to cooling simultaneously following the defrost.

  • Page 392: Hardware Fault Alarm

    • In contrast to the general procedure for treating a sensor failure, the following applies in the case of discharge gas defrosting: This procedure serves to prevent false alarms when, during discharge gas defrosting, the defrost sensor becomes so warm that it exceeds the temperature range of the controller. 11.1.6 Hardware fault alarm Alarm is generated without delay if the controller detects hardware problems.

  • Page 393: Individual Allocation Of Priorities

    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.
  • Page 394  • If an alarm with a controller priority > 0 is pending and this priority is set to 0 before the alarm has been marked as gone, the controller has no possibility to reset the alarm in the store computer. Therefore, it is recommended after any change of alarm priorities to the value 0 to restart the controller or ensure that the adjusted alarms are not active at the time of the adjustment.
