User manual ERC 113 refrigeration controller

Introduction

ERC 113 The ERC 113 is an electronic stand-alone

controller designed to optimise total cost savings. Particularly suited for OEM customers, the controller easily meets requirements for a time-saving and ﬂexible production setup. Programming can be carried out in just 10 seconds using the unique Danfoss docking station. Moreover, the ERC 113 is easy to mount and comes with just one code number to facilitate inventory management.

In addition to the stand-alone setup, the ERC 113 can be integrated with a remote display or a remote spindle to make it uniquely versatile. The modular system eﬃciently accommodates the varying require- ments encountered with, for example, beer coolers, commercial freezers and glass door merchandisers.

The ERC 113 is built using the very best hardware technology and is the only controller on the market to oﬀer a waterproof spindle.

For those customers without the need of a display and buttons, ERC 113 self contained unit controller oﬀers a very cost eﬀective solution. The controller’s ﬂexibility includes an optional remote spindle (same look and feel as mechanical controls) or remote display, then oﬀering an advanced user interface.

ERC 113 in combination with the IP65 rated remote spindle ideally suits refurbishment markets, where mechanical controls need to be replaced with energy saving solutions, for instance in bottle cooler and vending machine applications. At the same time, the design meets automotive standards in terms of mounting speed and maintenance.

ERC 113 with the Danfoss remote display oﬀers an advantage in for instance cassette design bottle coolers, where the display is mounted on the canopy, but the controller resides in the compressor compartment. For many commercial fridge and freezer applications, this split solution oﬀers a higher degree of ﬂexibility, due to size and an additional ﬁfth relay.

The IP-rated body, advanced materials and internationally approved hardware design of the ERC 113 make it suitable for use in almost any climate around the world, indoors as well as outdoors. All components have been carefully selected to help reduce the CO2 footprint of the controller.

User manual ERC 113 refrigeration controller

Overview of the ERC 113 application setups: stand-alone, remote display and remote spindle.

The ERC 113 stand-alone controller can be equipped with a variety of accessories, including remote display, remote spindle and multiple sensors.

Overview of the system The ERC 113 stand-alone controller is easily

programmed using the Danfoss docking station or a gateway. Connect your PC to the USB gateway and the USB gateway to the ERC 113 and conﬁgure all parameters online. Use the gateway for various monitoring purposes in your laboratory, e.g. to verify your parameter setting.

Docking station: download the desired parameters from a computer to an EKA 183 with USB interface. Then put the EKA 183 into the Danfoss docking station and place the ERC 113 controller on the docking station to download the parameters from the EKA 183.

Gateway: download the desired parameters from a computer to the gateway. Then plug in the gateway into the ERC 113 controller to program it.

ERC 113 can also communicate with remote displays (e.g. RDI 107) over 1 wire communication interface or it can be controlled by the remote spindle RSP 01 through an edge connector.

Application setup

1) ERC 113 stand-alone

2) ERC 113 + remote display

The ERC 113 is an IP-rated stand-alone controller for use in applications such as beer coolers and counter-top bottle coolers (e.g. in petrol stations). With input from multiple sensors, the cost-eﬃcient controller delivers energy-saving routines as well as providing control of compressor, light, fan and defrost functions.

Using the Danfoss docking station, programming of pre-prepared parameter settings can be achieved in just ten seconds

The ERC 113 + remote display (RDI 107) is ideal for commercial freezers and fridges as well as glass door merchandisers.

ERC remote displays allow for temperature indication and user interaction alike in an embedded controller but with the ﬂexibility of a split system (up to 3 meters cable length)

3) ERC 113 + remote spindle

The ERC 113 + remote spindle provides a controller solution with the look and feel of mechanical thermostats, ideally suiting refurbishment solutions and cost optimized commercial refrigeration equipment.

The remote spindle wiring is available up to 3 meters length. The spindle oﬀers a stop function (appliance ON/OFF switch)

Conﬁguration of inputs and outputs

ERC 113 inputs and outputs

Possible input and output connections

The ERC 113 inputs and outputs are conﬁgurable by the customer. Before getting started it is a good idea to check if all inputs are conﬁgured correctly and match the sensors attached.

Input and output conﬁguration settings are part of the assignment menu "ASi".

NOTE: Coded sensors will impact on the number of

possible conﬁgurations

For instance: Danfoss supplies only 2-pole defrost sensors, so input "S3" will most likely be used as a defrost/evaporator temperature sensor input.

Please contact your local Danfoss representative for information about default settings.

NOTE: remote display is always connected to the

digital input "Di" an d conﬁgured as "buS", whilst remote spindle is always connected to "S3" and conﬁgured as "rSp"

Set point

This parameter deﬁnes the desired temperature (set point). In standard operation the set point is changed by simply pressing the "temperature up/down" buttons on ERC 112; for laboratory and assembly line you may opt for software controlled set point adjustment (speed improvement)

Current set point adjustment value diF * SPr

The default value is set to 0.5 and the parameter is hidden by default. "Spr" deﬁnes the position of the set point in relation to cut-in and cut-out. "Spr=0,5" sets the set point mid between cut-in and cut-out. "Spr=0" sets the set point at the cutout. "Spr=1" sets the set point at cut-in.

Thermostat diﬀerential

This deﬁnes the diﬀerence between the cut-out and the cut-in. The desired temperature is determined by "SPr" and "diF".

Upper limit of thermostat set point

Deﬁne the temperature range limit of the controller. Once set, the desired temperatue (set point) can not go above "HSE" or below "LSE".

Lower limit of thermostat set point

Deﬁne the temperature range limit of the controller. Once set, the desired temperatue (set point) can not go below "LSE".

Initial cut in

Comp relay action when Tair is between cut-in and cut-out at power-up: "yES": cut in the compressor. "no": cut out the compressor.

Spindle stop angle Set to zero to disable stop function. Set to 30 to enable stop function.

Fan control method

"FAo": fan always on "SEt": fan follow compressor by manually settings "Aut": automatical fan control

Fan ON Delay/Fod

Fod deﬁnes the fan delay (in seconds) after a compressor cut-in.

Fan Stop Delay/FSd

"FSd" deﬁnes the fan delay after a compressor cut-out.

If both "Fod" and "FSd" are set to zero then the fan runs whenever the compressor runs.

Fan ON Cycle/FoC Fan Stop Cycle/FSC

When the compressor is OFF, and "FoC" or "FSC" are not zero, the fan runs in cycles according to "FoC" and "FSC".

Example: "FoC=120" [sec] and "FSC=120" [sec] means that the fan runs for half the time when the compressor is OFF. When the compressor is on, the fan is always ON (according to "FAo" and "Fod").

Light OFF delay

Number of seconds the light will stay ON after the door has been closed.

Pud Pull Down settings

Pull down (sometimes known as Super Cool) is a procedure for improving cooling performance, accelerating the time used to reach the desired temperature. Pull down settings overrule all other settings.

"Pit"

Min. -40.0°C Max. 50.0°C Default 50.0°C

Pull Down Initiate Temperature

This parameter indicates the temperature which causes a pull down to start. If the temperature measured inside the cabinet exceeds this value for longer than one hour, then pull down will start. The compressor will have already cut-in, so the only eﬀect is to stop defrost cycles until the desired temperature is reached. The period of one hour is ﬁxed and cannot be altered.

"PCy"

Min. 0 min Max. 360 min Default 30 min

"Pdi"

Min. 0 hour Max. 48 hour Default 15 hour

"Pdd"

Min. 0 hour Max. 48 hour Default 24 hour

"PLt"

Min. -55.0°C Max. 55.0°C Default 0.0°C

Pull Down Cycling

This is the duration in minutes of the compressor cycling at the reduced set point temperature. Once the desired pull down limit temperature "PLt" has been reached during pull down, the compressor will continue to cycle ON/OFF for the duration of "PCy". At the end of the period deﬁned by "PCy", the set point temperature will return to normal and pull down will cease.

Pull Down Defrost Interval

Even though most applications do not need Defrost during pull down, an extended defrost during pull down can be applied. This is the time between defrost cycles during pull down. It is measured in hours and can be up to 48 hours. During pull down, this setting overrides the defrost interval and defrost time settings (see the defrost section).

Pull Down Duration

You can choose to limit the maximum pull down time. Once this time value (max. 48 hours) is reached, pull down will stop regardless of whether the desired pull-down temperature has been reached.

Pull Down Limit Temperature

This parameter sets the minimum allowed temperature during pull-down. In order to protect valuable contents you must always specify the absolute minimum temperature allowed in your application. For glass door merchandisers 0°C/32°F protects bottles from freezing; for commercial fridges you may opt for a slightly higher temperature (e.g. 2°C)

Terminate Temperature

This parameter deﬁnes at what temperature the defrost cycle will stop. The temperature is given by the evaporator sensor or by the cabinet temperature sensor if no evaporator sensor is used.

Defrost reset temperature

The defrost counter is saved and restored at power-up, but if the temperature sensor, used for defrost, is higher than this value at power-up, it is assumed that the evaporator is free of ice and the defrost counter will be cleared.

"dii"

Min. 1 hour Max. 96 hour Default 6 hour

Defrost minimum Interval/dii

Deﬁnes the minimum time period between the start of two defrost cycles. Once the minimum interval has expired, the defrost cycle will start at the following cut-out or once the maximum interval "dAi" has been reached.

"dAi"

Min. 1 hour Max. 96 hour Default 7 hour

"Fdd"

Min. 0 s Max. 600 s Default 0 s

Maximum Interval

Deﬁnes the maximum time period between the start of two defrost cycles.

Minimum Time

Deﬁnes the minimum duration of a defrost cycle. During this period, the controller will not check the temperature. Once the minimum time has expired, the temperature will be checked and if the terminate temperature "dtt" has been reached, the defrost cycle will end. If dtt has not been reached, defrost will continue until either dtt is reached or the maximum time "dAt" reached, whichever occurs ﬁrst.

Maximum Time

Deﬁnes the maximum duration of a defrost cycle. The controller will not allow a maximum time to be entered which is less than the minimum time, or a minimum time which is more than the maximum time.

Drip OFF Time

This parameter can be set to between 0 and 60 minutes and deﬁnes how long the delay is between the heater being switched OFF and the compressor starting again.

Fan Delay after Defrost

Deﬁnes how long the delay is between the start of the compressor after defrost and the fan starting again.

Fan Start Temperature

This only applies if an evaporator temperature sensor is ﬁtted. This parameter determines at what evaporator temperature the fan will start after a defrost cycle is complete. If the time set in "Fdd" occurs before the temperature set in "Ftd", the fan will start in line with "Fdd". If the temperature set in "Ftd" occurs ﬁrst, then the fan will start in line with "Ftd". It is therefore a case of whichever parameter’s setting is reached ﬁrst which determines when the fan starts.

Defrost Fan On

Set to "yES", the fan will constantly run during defrost cycles. Set to "no", the fan will not run during defrost cycles.

Defrost ON Compressor Time

If this parameter is set to "yES", then defrost time is considered only when compressor is ON, so that defrost cycles are based on the total time the compressor has been running. If this parameter is set to no, then defrost cycles are related to elapsed time, regardless of how long and how often the compressor has been on.

Defrost by Comp. running time

Continuous compressor running can cause defrost. "0" = deactived

Initial Defrost Interval

The initial defrost interval determines the time for ﬁrst defrost after power-up. The initial defrost is mainly intended for factory testing of the defrost functionality and can be set to expire after a number compressor cycles according to the setting of parameter idd. During normal operation, the defrost counter will be saved in memory and restored after power loss, making the initial defrost unnecessary.

"idd"

Minimum cut-in voltage/uLi. Minimum cut-out voltage/uLo. Maximum voltage/uHi

These three parameters provide voltage protection to the compressor. Start by setting "uHi", followed by "uLo" and "uLi". "uLi": when the compressor is due to start, the voltage of the power

supply will be checked and the compressor will only be allowed to start if it is at least the value given in this parameter.

"uLo": when the compressor is running, it will be switched

OFF if the voltage goes below that given in this parameter.

"uHi": when the compressor is running, it will be switched

OFF if the voltage exceeds that given in this parameter. If the compressor is already stopped, it will remain switched OFF.

Sensor Error Type

"no": no sensor error handling. "SEt": in case of control sensor error, follow error run/stop time. "Aut": automatical sensor error handling.

Error Run Time

The parameter only become active in the unlikely event of a broken temperature sensor. It is used to run the application in safety mode. At the same time the sensor error will be shown in the display. "Ert" deﬁne the duration the compressor will run. Example: "Ert=4" [min] and "ESt=16" [min] will provide an average cooling system activity of 20%. Ert and "ESt" values are based on OEM experience and are by default inactive.

Error Stop Time

Minimum Stop Time

It determines the minimum number of minutes the compressor must remain idle before a Temperature cut-in can take eﬀect. For example, if the temperature sensor indicates that the cut-in temperature has been reached, but the number of minutes set in this parameter have not elapsed since the compressor last stopped, then the compressor will stay OFF. It will only start once the duration given by "CSt" has been reached provided the temperature is still high enough. "CSt" thus overrides the cut-in.

Minimum Run Time

It determines the minimum number of minutes the compressor must run before a Temperature cut-out can take eﬀect. For example, if the temperature sensor indicated that the cut-out temperature has been reached, but the number of minutes set in this parameter have not elapsed since the compressor last started, then the compressor will continue. It will only stop once the duration given by "Crt" has been reached – provided the temperature is still low enough. "Crt" thus overrides the cut-out.

Maximum OFF Time

This is the maximum time in minutes the compressor is allowed to "idle" – up to 480 minutes. Cot is set to zero by default (inactive). If the controller is used on a draft beer (ice bank) application, this parameter can be used to control the ice thickness.

Compressor Door Open Delay/Cdd

This parameter sets the delay in minutes before the compressor stops when the door is opened. If set to zero, the function is disabled.

System resume after door open

Fan and Compressor resume after cut out by door open.

This parameter can be set to 0.1, 0.5 or 1 and aﬀects the way the temperature is displayed. With the parameter set to 1, the display will only ever show temperatures rounded to the nearest whole degree. At 0.5, it will round the temperature to the nearest half degree for display. For example, 3.3 degrees will be shown in the display as 3.5 degrees and 3.9 as 4.0. With the parameter set to 0.1, no rounding occurs. This parameter does not aﬀect the temperature itself, merely the display.

In some point of sales applications you may want to show the desired instead of the real temperature. This parameter sets whether the displayed temperature is the actual temperature or whether it is restricted to the cut-in / cut-out limits. Set to "nO" means that the actual temperature will de displayed. The parameter is set to "nO" by default.

Display Delay

In order to provide a realistic temperature appearance for an application, a display delay can be set. The parameter sets the time constant τ (tau) of the moving average ﬁlter for the display. Physically, one time constant represents the time it takes the system’s step-response to reach 66% of its ﬁnal value and ﬁve time-constants the time it takes to reach 99% of its ﬁnal value.

Display Oﬀset

This parameter is a relative value and allows the temperature displayed to be diﬀerent to the temperature measured. For instance, at a measured temperature of 7°C and "doF" set to -2K, the displayed temperature will be 5°C instead.

Lock Time After Defrost

In order not to show a rising temperature during defrosting, the displayed temperature is locked at the temperature shown at the start of the defrost cycle for the number of minutes set in this parameter. "0": no lock.

Show Economy State

If set to "yES", this parameter causes the display to show ECO when the system is in ECO mode. If set to "nO", the temperature continues to be displayed.

Show Pull down state

If set to "yES", this parameter causes the display to show SC when the system is in pull down mode. If set to "nO", the temperature continues to be displayed.

Show Holiday

"no": display will show temperature or ECO mode during holiday mode. "yES": display will show "HoL" during holiday mode.

Show Defrost

If set to "yES", this parameter causes the display to show DEF when the system is in defrost mode. If set to "nO", the temperature continues to be displayed.

Alarm delay on high temperature alarm

The number of minutes to wait before sounding an alarm once the high temperature alarm temperature is reached.

Alarm delay on low temperature alarm

The number of minutes to wait before sounding an alarm once the low temperature alarm temperature is reached.

Pull down delay

Normally, it is not necessary or desirable to sound an alarm during a pull down (the initial phase of reaching the desired temperature). This parameter prevents the high temperature alarm "HAt" sounding during pull down and after a defrost for the number of minutes set for the parameter. NOTE: it does not apply to the low temperature alarm "LAt".

"dod"

Min. 0 min Max. 60 min Default 2 min

Door Open delay

It is possible to indicate to customers that a door has accidentally been left open. This parameter sets the delay in minutes before the alarm sounds. This is useful in environments where customers/users may hold the door open while making their selection. If the door is closed again before the set number of minutes is reached, the alarm does not sound. NOTE: a door sensor is required if this parameter is to be activated.

"no": no voltage alarm. "yES": voltage alarm activated.

Leakage alarm

Leakage detection for compressor protection. "0": disable

Alarm Buzzer Duration

The alarm sounds for 10 seconds, followed by silence for 50 seconds. One alarm sequence therefore lasts 60 seconds. These values cannot be changed. This parameter determines how long in minutes an audible alarm will continue while there is still a reason to have an alarm. If set to 999, the alarm will continue to sound until the reason for the alarm is cleared – for example the temperature has dropped enough or the door closed. In some cases, it may be necessary for a user or technician to take action in order to clear the alarm. If set to 0, the alarm will never sound.

"ACA"

Min. no Max. yes Default yes

Auto Clear of Alarm/Error/ACA

If this parameter is set to "nO": The alarm status will not disappear automatically even if the condition which caused the alarm is no longer valid or present. If set to "yES": As soon as the condition which caused the alarm is no longer valid or present, the alarm status will automatically change back to inactive. There will be no trace of the alarm having occurred. In general, glass door merchandise applications will be set to "yES" and commercial fridges and freezers set to "nO". For example, if the temperature goes too high for a period there may be food safety considerations in a freezer containing food but not in a fridge with cold drinks.

AHC Automatic Heater settings

Automatic Heater Control applies reverse cooling mode (heating) to your refrigeration appliance. This feature requires: A) that your appliance is exposed to ambient temperatures

below the desired temperature in your cabinet (e.g. very cold climates and outdoor use).

B) a special heater (for example a large defrost heater) built in

to your appliance.

Air Temperature Adjustment (applies to non-Danfoss temperature sensors only)

This parameter is a relative value and allows adjustment of the control sensor temperature. For instance, at a measured temperature of 7*C and "tAd" set to -2 K, the input from the control sensor will be 5*C instead.

"t3A"

"t4A"

Inputs and outputs are conﬁgurable

There are two steps:

1. Deﬁne the type of sensor attached to the input:

- temperature: light/digital.

2. Deﬁne the application for the sensor:

- temperature: control/condenser/evaporator.

- light: ECO/display/both.

- motion

- digital: door sensor. Please contact your local Danfoss representative for information about default settings.

NOTE: coded sensors will impact on the number of possible conﬁgurations. For instance: Danfoss supplies only 2-pole defrost sensors, so input "S3" will most likely be used as a defrost/evaporator temperature sensor input.

User manual ERC 113 refrigeration controller

Sensor placement

Control sensor

The control sensor must always be connected and is used for controlling the cut-in and cut-out of the compressor according to the set point. The sensor is also used for the displayed temperature.

Vertical coolers with fan

Most common placement is in the return air to the evaporator. The sensor can be placed close to the fan – even when the fan is pulsed during compressor OFF periods: the updating of the temperature is blocked when the fan is stopped and only updated when the fan has been running for a while, so that the heat from the fan does not aﬀect the temperature reading. For applications sensitive to sub-zero temperatures, sensor placement in the evaporator outlet air can be considered.

Vertical freezers with fan

Placement in the return air or in the freezer compartment.

Coolers without fan

The best results are normally obtained when the sensor is placed at the side-wall, 10 cm from the back and approximately at 1/3 from the bottom or where the evaporator ends. The control sensor must always be connected and is used for controlling the cut-in and cut-out of the compressor according to the set point. The sensor is also used for the displayed temperature.

Evaporator sensor

The evaporator sensor is only used for de-icing of the evaporator and has no control purpose.

Placement of sensor

Place the sensor where the ice melts last. Please be aware of that sharp ﬁnns can damage the cable.

User manual ERC 113 refrigeration controller

Condenser sensor

Ambient light sensor

The condenser sensor is used to protect the compressor against high pressure when the condenser is blocked or the condenser fan fails.

Placement of sensor

Place the sensor at the liquid side of the condenser. Use a metal bracket or metal tape to ensure good thermal conductivity. Be sure that the cable does not pass hot spots at the compressor or condenser that exceeds 80°C.

The ambient light sensor is used to detect opening hours of the shop.

Placement of sensor

The sensor must be placed so that the interior light does not aﬀect the sensor. Possible placement could be in the front of the cooler or at the top.

Door sensor

Produced by Danfoss A/S (ADAP-KOOL®) | 2016-07

DKRCC.ES.RL0.F5.02

The door sensor is used to detect buying activity and to stop the fan when the door is opened.

Door sensor

Danfoss does not supply the door-switch. Use the door-switch you have and connect it to the cable supplied by Danfoss.
