  dt: End defrost temperature This parameter allows the end defrost temperature, as measured on the evaporator, to be set. In any case, the maximum defrost time is equal to the value, in minutes, set for parameter dP. When the temperature measured by the defrost end probe is higher than the defrost end temperature set by the user, the defrost cycle will not be performed, that is, only the following dripping and, if required, post-dripping phases will take place.

• Page 16: Programming

  6. Programming The microprocessor in the MPX instruments allows the configuration of the functions of the controller according to the application requirements. To simplify this operation, we have divided the operating parameters into two main groups: • frequently used parameters (indicated as ‘F’ parameters in the tables below); •…

• Page 22: Re-Configuring A Control With The Default Parameters

  8. Re-configuring a control with the default parameters Under exceptional conditions − high electromagnetic noise levels, for example − there may be errors when storing data. Consequently, the unit may not work correctly. When the microprocessor identifies an error in the process of storing data, one of the following groups of letters will be displayed: EA, EB, -E- The last symbol will only appear at the start-up of the instrument.

• Page 23: The Alarm Log

  9. The alarm log All the models in the MPX Series are fitted with an alarm log that records up to until 9 alarm signals. The models configured as Master and fitted with RTC also allow the display of the age of each alarm, that is, the time in hours elapsed between the moment in which the log is consulted and the time the alarm was recorded.

• Page 24: New Local Network Functions

  10. New local network functions 10.1 Network defrost for multiplexed systems The Master controls the defrost in the entire multiplexed island (cabinet controlled by the Master + cabinets controlled by the Slaves). This waits for all units to exit the actual defrost stage before sending the end defrost command to the entire network. The Slaves which have exited the actual defrost stage, await the end defrost command from the Master before passing to the dripping stage.

• Page 25: Description Of The Configuration Parameters

  11. DESCRIPTION OF THE CONFIGURATION PARAMETERS 11.1 Configuration parameters As already mentioned, (see chapter on how to modify the operating parameters), there are two types of parameter: • parameters used frequently (indicated by ‘F’ in the following tables) • configuration parameters (type C), which are protected by a password to prevent unwanted modification. 11.2 Parameter categories Besides being divided into TYPES, the parameters are grouped into logical categories labelled by letters indicating their function.

• Page 26: Parameters For The Management Of The Temperature Probes

  Short descriptive note about probes with NTC- and PTC-type thermistors: Units in the MPX series are designed to work with Carel NTC temperature probes, or probes using thermistors with a negative characteristic (NTC stands for Negative Temperature Coefficient). This type of thermistor modifies an electrical parameter (its own resistance) in inverse proportion to any change in temperature;…

• Page 27
  /2: Stability of measurement This parameter is used to control the stability with which the temperature is measured. Low values assigned to this parameter produce a prompt response by the probe to variations in temperature; however, the display becomes correspondingly sensitive to changes. High values slow down the response, causing less fluctuation and a more stable reading.

• Page 28: R = Parameters For Temperature Regulation

  /9: defrost with probe 3 This parameter allows a defrost to be carried out using probes S2 and S3 together, if set to 1. In this case the temperature defrost ends when the temperature measured by both probes is greater than or equal to that set as the end defrost temperature (See parameter “dt”). Probe 3 can therefore be used as a defrost probe on a second evaporator.

• Page 29
  rd: Regulation delta Sets the value of the differential, or hysteresis, used in regulating the temperature. A narrow differential, i.e. one with a low number, ensures a temperature that differs little from the set-point (or optimal operating temperature), but one that requires the frequent switching on and off of the main operating components (normally the compressor).

• Page 30: C = Parameters For Compressor Management

  To inhibit monitoring and/or reset the values recorded, set “r5” to 0. After 199 hours the measuring of the max. and min. temperatures is halted, having reached the maximum monitoring time allowed by the instrument. Modify “r5” to perform monitoring again (first set to 0 using the arrows and the SEL button and then to the required value between 1 and 5, again using the arrows and SEL.

  c0: Delay in switching on the compressor and fans (if controlled) after switching on the instrument From when power is supplied to the controller, the start-up of the compressor is delayed by a time (in minutes) equal to the value assigned a this parameter.
• Page 32
  c4: Duty setting or safety relay If the “regulation error” alarm occurs (that is, probes S1 and/or S3 are short-circuited or disconnected) this parameter ensures the operation of the compressor until of the elimination of the fault. As the compressor is unable to function based on the temperature (because of the faulty probe), it is activated cyclically with an operating time («ON time») in minutes equivalent to the value assigned to c4 and a fixed OFF time of 15 minutes.

  dt: End defrost temperature set-point This parameter allows the setting of the temperature of the evaporator at which the defrost is ended (the temperature of the evaporator is measured by the defrost probe: probe 2). If at the start of a defrost (d0 = 0) the temperature measured by the defrost probe is greater than the set end defrost temperature, the unit goes directly to the dripping phase (See further on, network defrost).

The low temperature alarm is given as follows: Low temperature alarm <…

  When the alarm ceases the unit resumes normal temperature control operation. WARNING: If A8 = 1 the alarm can be activated by a specific command from the supervisory system (if the latter exploits the functions supplied by the MPXs) or, on Slave units where A8 = 1, by the opening of the digital input DIN2 on the Master. Important note: it should be remembered that to guarantee the safety of the unit in the case of serious alarms, the unit itself must always be fitted with all the electro-mechanical safety devices needed to ensure correct operation.
• Page 39
  A4/A5/A8 = 5: Door Switch Setting A4/A5/A8= 5 controls the switch on the store-room door. When the switch is opened the compressor and the fans are switched off and the lights are switched on (if at least one of the two fan or AUX relays is configured as an auxiliary and is used as a light relay). When the door is closed (as well as the Multifunction contact), the unit resumes the previous operation, delaying any temperature alarm by a number of hours equivalent to the value of d8.
• Page 40
  A9: Enable the propagation via the LAN of the Master’s second digital input This parameter is accessible only for instruments configured as Master. It allows “parallel connection” to the virtual digital input on the connected Slave units of the Master’s second (physical) digital input DIN2. In this way, the second digital input of the Master may be propagated or not to the Slaves.
