• Page 33: Ems Controllers Functionality

  EMS controllers functionality EMS controllers have the capability to manage the following: Temperature: EMS controllers measure the air temperature of the refrigeration compartment to control the temperature of the products. EMS controllers ensure that products are at the optimal serving temperature. Condenser: EMS controllers manage the temperature on the condenser to prevent high temperature.

• Page 34: Evaporator Fan Management

  Note: Manual defrosts also end after the defrost duration (dd) or on reaching the defrost termination temperature (dtd).

  Passing peak current through the windings of the compressor motor Switching off the refrigeration system on the thermal overload protection Short-cycling the refrigeration system. However, if ready mode and saving mode differential temperatures are too small or if the compressor rest time (rt) is too short, the EMS controller cycles the compressor on the compressor rest time (rt) as the compressor rest time (rt ) overrides the differential temperatures.

• Page 37
  However, to compensate for differences between the air temperature and the product temperature, calibration 1 (C A1) can add an offset to the temperature measured on the appliance sensor. See «Calibration 1 (CA1)» on page 68 EMS controllers can be set to use Celsius (°C) or Fahrenheit (°F) — set by the Celsius or Fahrenheit (C F) parameter.

• Page 38: How Ems Controllers Work — Self-Learning

  How EMS controllers work — self-learning EMS controllers monitor the cooler activity to record consumer patterns. EMS controllers use the learnt patterns to switch between the following modes: Ready mode the product is at the correct serving temperature and the cooler lights are on. Saving mode the product temperature is allowed to rise to save energy and the cooler lights are off.

• Page 39: How Ems Controllers Work — Example

  Controllers can then switch to the saving mode to allow the product temperature to rise during peri- ods that outlets are closed and switch to the ready mode to ensure that the product is at the correct serving temperature when outlets open, as shown below. After the learning period ends, controllers continuously update the self-learning matrix, therefore: If the cooler is moved, the controller updates the self-learning matrix from the previous location with the activity from the new location.

• Page 40
  During self-learning, EMS controllers learn the periods that outlets are open or closed by measuring the activity. EMS controllers have a self-learning matrix. The self-learning matrix is a 7-day (7 x 24 hour) matrix. Each 24 hour period consists of 48 30-minute periods. EMS controllers then set each 30-minute period with activity or without activity according to the out- let opening and closing pattern.

• Page 41: What Is The Self-Learning Matrix

  See «Activity frequency (AF)» on page 76 See «Learning period (LP)» on page 77 What is the self-learning matrix? The self-learning matrix is a 7 day (7 x 24 hour), matrix with each 24 hour period divided into 48 30- minute periods.

• Page 42: Activity Frequency

  EMS controllers use activity to determine when retail outlets are open and closed. Periods with activ- ity mean the retail outlet is open, and periods without activity mean the retail outlet is closed. EMS controllers run coolers in the ready mode during periods with activity and the saving mode during periods without activity.

• Page 43
  EMS controllers then update the self-learning matrix depending on how much activity is detected in each 30 minute period as follows: If the EMS controller detects activity during a 30 minute period, the EMS controller changes the state from mon- itor (1) to ready (2) If the EMS controller does not detect activity, the EMS controllers changes the state from monitor (1) to saving (0).

• Page 44: How A 7-Day Learning Period Works

  EMS controllers with a one day learning period start switching to the saving mode on the second day, (second 24 hours), if there are sufficient saving (0) periods. EMS controller then continue to update the self-learning matrix as follows: For periods set to ready (2), if no activity is detected change to monitor (1). Otherwise, keep the period set to ready (2).

• Page 45
  matrix. For periods set to monitor (1), EMS controllers run in the ready mode. EMS controllers then update the self-learning matrix depending on how much activity is detected in each 30 minute period as follows: If the EMS controller detects activity during a 30 minute period, the EMS controller changes the state from mon- itor (1) to ready (2) If the EMS controller does not detect activity, the EMS controllers changes the state from monitor (1) to saving (0).

• Page 46: Saving Mode

  Saving mode EMS controllers run in the saving mode when retail outlets are closed. In the saving mode, the product temperature is allowed to rise to a predefined temperature. The sav- ing mode temperature range is defined by saving set point (S S P) and the saving differential (S d). The compressor runs until the saving set point (S S P) temperature is reached and then stops until the measured temperature reaches the saving set point (S S P) plus saving differential (S d) temperature.

• Page 47: How Ems Controllers Switch Between The Ready And Saving Mode

  If the cooler door is opened or the motion sensor detects activity during the saving mode, EMS con- trollers switch on the cooler lights for the remainder of the current 30-minute period, but do not start cooling cycle. For more information about the parameters used in saving mode: See «Saving temperature disable (PEr)»…

• Page 48: Ready Mode

  In the following example matrix, the EMS controller will start to cool by the saving restart period before the ready period (2), run in the ready mode for 30 minutes, and then switch to the saving mode (assuming no delay to saving dsparameter is in operation). For more information about the parameters used: See «Delay to saving (dS)»…

• Page 49: How The Self-Learning Matrix Updates After The Learning Period

  At the end of the ready mode, EMS controllers switch to the saving mode. However, the delay to saving (dS) parameter can delay the switch to the saving mode. The delay helps ensure that, for example, the EMS controller remains in the ready mode during periods without activity immediately prior to out- lets closing for marketing purposes.

• Page 50: What Are The Accessories

  Temperature sensors Temperature sensors are available from Elstat with various cable lengths. To help identify sensor cables during the installation, Elstat can supply sensor cables with blue identification sleeves.

• Page 53: Door Switch

  For coolers fitted with a defrost heater, the evaporator sensor should be placed as far away as pos- sible from the heating element, i.e. at the opposite end of the evaporator. If the evaporator sensor measures the localized heating from the heating element, defrost cycles will terminate before the whole evaporator has had the opportunity to defrost.

  The screws must be tightened to a maximum torque of 0.5Nm (0.37lb ft). Caution: Door switch kits supplied by Elstat must not be installed using rivets. Using rivets invalidates the war- ranty. The alignment of the door switch and activator is critical for the correct operation of the door switch.

• Page 55: Motion Sensor — Ems75Sz

  As the motion sensor cannot monitor activity through glass or plastics, the remote motion sensor varient of the ems75sz CDM has been designed to be installed into header panels inside the cooler cabinet. The remote motion sensor may then be installed where it will be able to ‘view’ activity.

• Page 56: Motion Sensor

  The CDM is manufactured from food grade plastics. 7.10 Motion sensor Motion sensors are passive infra-red (PIR) devices that detect activity. The diagram below shows the detection pattern of motion sensors. The motion sensor must have an uninterrupted view directly in-front and to the sides. The preferred location of the motion sensor is in the upper section or in header panel of the cooler to ensure the best motion detection and to lower the risk of the motion sensor being blocked by objects such as packages.
