Other Information

Alarms/Warnings:

During operation the current temperature inside the appliance will be displayed. At certain times this will change to indicate a particular appliance operation or fault. The indicators you may see are as follows:

The temperature alarms are either relative to the set point or an absolute value. This is controlled by the value of parameter ‘ATM’. Where the alarms are relative the low alarm is the set point minus parameter ‘ALR’ and the high alarm is the set point plus ‘AHR’. When the temperature has been outside this value for the value of ‘ATD’ the relevant indicator will be displayed.

hi – The internal temperature of the appliance is higher than it should be. Ensure that the door is closed and that the air flow inside is not obstructed by excesive or poor loading of product. The alarm will reset if the temperature falls to a normal level.

Lo – The internal temperature of the appliance is lower than it should be. Check to ensure that the appliance has not been loaded with product at a lower temperature than the normal appliance operating temperature.

dO – The appliance door is open. Close the door to cancel the alarm. Note – the door switch is a magnetic switch located in the bottom edge of the front cover. If the cover is hinged up or removed for access purposes, the door switch will not function and the door open alarm will be displayed.

tA – This indicates that the internal temperature probe has failed. During this time the appliance cannot maintain an accurate temperature and all product should be removed and the appliance switched off.

tE – This indicates that the evaporator probe has failed.

PF – The mains power has been removed from the appliance for a period of time and has now been restored. This may have resulted in a rise in appliance temperature. Caution should be taken when using products stored within to ascertain whether these products are suitable for use. Upon restoration of the power supply the appliance will resume normal operation and the PF can be cancelled by pressing button 1 once.

hc – The condenser temperature is higher than it should be. If the appliance is being subjected to particularly high ambient temperatures steps should be taken to reduce this.

Cnd – The condenser clean period has expired.

While in an alarm condition icon ‘a’ will also be illuminated. The audible alarm can be muted temporarily by pressing button 1.

(Some indications are only visible periodically during specific appliance operations such as defrost or when activated through use of the appliance).

Probe Information

The probe is a type 10k NTC. The probes are identical in characteristics with the T1 and T2 identification markings and different colours being for ease of identification and not for functional reasons. Please refer to the image below for probe identification.

NTC10K Temperature Resistance Table SN4K

Refrigerant Charge

The refrigerant charge weight can be found on the serial label within the appliance. Where this is not available please refer to the table below. The information below is correct time of printing but is subject to change without prior notice.

Door Switch

The appliance is fitted with a magnetic door switch located in the underside of the front cover. Where the door switch is open and following the time set in parameter ‘DAD’, the controller will indicate ‘do’ and an alarm will sound. At the point the door is opened the evaporator fan(s) will stop and following the time set in parameter ‘cSd’ relay 1 will open until such time as the door is closed.

Defrost Indication

During defrost icon ‘c’ will be illuminated. The controller display will be determined by the value set in parameter ‘ddM’.

To start a defrost manually press and hold button 1 for 5 seconds. This will turn off the appliance. Continue to hold down button 1 after the appliance has turned off. After a further 2 seconds the display will indicate a defrost has commenced (icon ‘c’ illuminated) and the button can be released. While the defrost function is operating icon ‘c’ will be illuminated and icon ‘g’ will flash.

Where parameter ‘tE’ is set to ‘YES’ the defrost will operate until the temperature set in parameter ‘dLi’ or the time set in parameter ‘dto’ is reached. Where parameter ‘tE’ is set to ‘no’ the defrost will operate until the time set in parameter ‘dto’ is reached. Upon completion of the defrost cycle the appliance will resume normal operation with the current temperature displayed.

The defrost will operate for it’s full duration, it is not possible to cancel a defrost when it has started.

Relay Test

The controller contains a relay test function to enable the service engineer to operate individual relays, or a combination of relays for diagnostic purposes.

To access the relay test:

Press and hold buttons 2 and 4 for 5 seconds untilt he display shows ‘rL1’. Note – after 3 seconds the display will show ‘MdL’, continue to hold the buttons while this is displayed.

The controller is now in relay test mode.

• Select the relay to test by using buttons 2 and 4. When relay 1 is selected the display will show ‘rL1’ and icon ‘a’ will flash. This is repeated for relays 2 and 3 with icons ‘b’ and ‘c’.
• To activate relay 1 press button 1. Icon ‘a’ will illuminate. To deactivate relay 1 press button 1 again and icon ‘a’ will flash.
• To activate the selected relay press button 1. To deactivate the selected relay press button 1 again.
• When a relay is active the relevant icon (a, b or c) will be illuminated.

Multiple relays can be activated simultaneously to enable diagnostics.

Relay function:

• Relay 1 – Icon ‘a’ – Compressor.
• Relay 2 – icon ‘b’ – function determined by parameter ‘rL2’. Evaporator Fan.
• Relay 3 – icon ‘c’ – function determined by parameter ‘rL3’. Where appliance has an active defrost rL3 to will be set to ‘dEF’.

To exit the relay test function press button 3 once.

If no buttons are pressed for 30 seconds the controller will exit the relay test function and return to normal operation.

Factory Reset

Where the controller was originally programmed by Foster and is dedicated to a specific appliance type it is possible to return the setting to they’re original programmed state. If the controller was not programmed by Foster this function will return the parameters to the values in the original factory settings.

To reset the parameters:

• Press and hold button 2 for 3 seconds until the display shows ‘SP’.
• Press button 4 twice to display ‘rFP’.
• Press button 1 once and ‘rFP’ will flash.
• Press and hold buttons 2 and 4 for 3 seconds until the display shows ‘End’ and the display returns to the displaying the current temperature.

The original parameters as described above have now been restored.

If at any point the sequence of button operations and display indications are not completed the controller will, after 30 seconds resume operation with no changes to the parameters having been made.

Maintenance

Cleaning

Condenser

Regular cleaning of the condenser (located behind the front cover) increases energy efficiency and prolongs the life of your appliance. Never use a wire brush, abrasive or corrosive materials to clean the condenser. This should be carried out periodically, by a competent engineer as outlined in the Regular Maintenance section of this manual.

Gasket

All door gaskets should be inspected on a regular basis and replaced as necessary if damaged. To clean, wipe with a warm damp soapy cloth followed by a clean damp cloth. Finally dry thoroughly.

Shelves and Tray slides

The shelves and tray slides in the appliance can be removed for cleaning. The shelves are dishwasher safe however the vertical supports and tray slides should be cleaned with warm soapy water then rinsed and dried.
