  • Page 36: Cooling

    5.7 Cooling 5.7.1 Temperature control The regulation is performed via the opening degree of the E-valve (see chapter Control of the expansion valves). The regulation is carried out separately for each temperature zone using its own controller parameter set, whereby the temperature and superheat regulation is carried out by one PID controller for each.  It is automatically decided whether the refrigeration point temperature controller (evaporator section filling mode) or the superheat controller (maximum evaporator filling mode) is active.

  • Page 37: Control Of The Expansion Valves

    5.7.2 Control of the expansion valves The output of the opening degree for controlling the two electronic expansion valves of zone 1 and zone 2 is provided at the factory via the pulsing (PWM - pulse width modulation) of the two semiconductor relays EEV1 and EEV2 and the two analogue outputs AO1 and AO2 (only UA 410 E AC).
  • Page 38 Only UA 410 E AC Continuous motor expansion valves The opening degree is also output simultaneously via the two analogue outputs 0..10 V (corresponds to 0..100%) for the control of continuous motor expansion valves (factory setting): The following must be observed when using the analogue outputs: The opening degree at the two analogue outputs is only output if the coding switch 6 of the DIP switch S3 is also set to OFF (factory setting; for details, see chapter Control of continuous motor expansion valves.
  • Page 39 Continuous motor expansion valves with enable relay Some continuous expansion valves require an enable via an additional signal input. For example, the required signal - can be generated via a time relay using the pulsed semiconductor relay EEV1 or EEV2 (holding time t of the  time relay 10 sec. < t < 30 sec.) or - it can be realised using the "enable relay" function; the parameter "Freigaberel." (menu 6-3) must be configured to "ON"...

    11.1 Alarm signaling and monitoring 11.1.1 Coldroom door open alarm Controller type UR 141 NE, UR 141 TE Alarm is generated if the coldroom door remains open for an adjustable time. In the event of a permanently open door, an alarm is activated and the controller returns to cooling following the elapse of the adjustable alarm delay time.

  • Page 456: Low Temperature Monitoring T0

    11.1.3 Low temperature monitoring t0 This function initiates monitoring of the t0 transmitted by the pack controller to check for inappropriately low values and is used, amongst other things, for the early detection of instances where the case controller has been assigned to the “wrong” pack controller (for assignment, see menu 6-1).

  • Page 457: Alarm In The Event Of The Minimum Permitted Superheat Being Undershot

    11.1.5 Alarm in the event of the minimum permitted superheat being undershot An alarm signal is sent when the limit value ”Minimum Superheat” is undershot following the end of the  10 minute delay time and the opening degree was greater than 0%. 11.1.6 Sensor break alarm Alarm is generated after the set time delay if the controller detects sensor break or short circuit (menu 6-2-3).  Sensor break alarm is always generated in the case of sensors required for control functions. Sensor break is only alarmed on optional sensors when these sensors are not removed from monitoring by sensor scan (Menu 6-1).

  • Page 458: No Required Sensor Alarm

    11.1.8 No required sensor alarm If the controller detects that controllers indispensable for regulation are not connected (evaporator output sensor, evaporator input sensor in the absence of t from the pack controller; return air and supply air sensor simultaneously), then the alarm Sensor Break EEV Z1/2 is triggered. 11.1.9 Stall detect alarm EEV control stalled. This alarm is generated when the Stall Detect state occurs over a period of 3 restart repeats x 10 minutes = 30 minutes.

  • Page 459: Individual Allocation Of Priorities

    11.2 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 makes it possible to address alarm destinations in a targeted way and to adjust alarm signalling to individual requirements.

  • Page 460: Alarm Routes

    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.
