Alarm situations • On the occurrence of an alarm situation attempts must be made to find out the reason for the alarm and remove it as quickly as possible. If that is not successful the necessary measures must immediately be taken so that the stored goods do not sustain any damage. • At a temperature alarm the red LED alarm lights up and an acoustic signal sounds. In addition the corresponding alarm message appears on the display. • In the case of a powerfail alarm the green power LED and the red LED alarm flash and an acoustic signal sounds. The display is switched off but be temporarly switched on again by pressing any key. After a given time (setting: EXTRA - DISPLAY BACKL. TIMEOUT ) the display switches off again. The acoustic alarm can be suppressed for a set time by pressing the ENTER button. During a powerfail phase no parameters can be changed. • If the internal temperature rises above the upper limit during a powerfail phase a temperature alarm is triggered and entered into the History list. In the case of a door alarm the red LED lights up and an acoustic signal sounds. In addition the corresponding alarm message appears on the display Alarm History • The alarm history list contains all relevant data on temperature and powerfail events. The list contains up to 20 alarm situations. • The status message “HISTORY” indicates that new entries have been made in the list. • The alarm history list can be accessed via the “SHOW HISTORY” function in the EXTRA menu. Within the list you navigate by means of the UP and DOWN buttons. The first and last entry in the list are marked “BEGIN OF LIST” and “END OF LIST” • The following information is stored in the Alarm History : Temperature alarm : ALARM : type of alarm (HIGH ALARM or LOW ALARM) START : Start date and time of alarm situation END : End date and time of alarm situation AVG : Average temperature on the display sensor during the alarm situations. MAX / MIN : Maximum or minimum temperature value on the display sensor during the alarm situation (depending on the type of temperature alarm) Powerfail alarm : ALARM : START : END : AVG : POWERFAIL Start date and time of alarm situation End date and time of alarm situation Average temperature on the display sensor during the alarm situations • To delete the alarm history, select the function “DELETE HISTORY” from the EXTRA menu. 12 Rechargeable battery • The monitoring functions of the electronics during an interruption of the power supply for at least 48 hours are maintained by an integrated rechargeable battery. • This battery is automatically charged when the appliance is connected. • If the capacity of the battery is no longer sufficient to take over the control function, the error message “BAT.1 LOW/FAIL” appears on the display. • At the first starting up it may happen that the message „BAT.1 LOW/FAIL” appears. The message will disappear as soon as the battery is charged. • The battery should be pre-emptively replaced every 2 years. This replacement must only be carried out by a recognised service technician. Before dismantling the battery the appliance must be switched off and the plug pulled out. • The battery is a lead-acid storage battery that must be disposed of separately in the case of a fault. External Alarmfunction • There are two terminals with three floating contacts on the back of the unit that can be used to trigger an additional external alarm (visual or audible). • The upper contacts correspond to temperatureand door-alarm, the lower contacts correspond to a powerfail-alarm. • Pressing the ENTER-key in an alarm situation only switches off the internal audible alarm. The key does not interfere with the external alarm. The external alarm signal is only switched off once the cause of the alarm has been eliminated. • A voltage of between 12V DC and a maximum of 250V AC can be connected at the contacts. The maximum load must not exceed 8A. The minimum power rating is 100mA / 5V. TEMPERATURE-ALARM DOOR-ALARM POWERFAIL-ALARM Resting state Resting state Alarm Alarm Safety thermostat • All units are fitted with a safety thermostat. This thermostat switches off the compressor as soon as the inside temperature falls below +2°C, to prevent the goods being harmed by freezing. Interior fittings • Depending on the model series, heightadjustable drawers or racks are included as standard fittings. • The load must be evenly distributed over the drawers or racks. • Pull out the drawers using the handles only. • To remove the drawers (e.g. to clean them), pull the draw out to the stop and then lift. • The appliances are designed in such a way that they have optimal function with the original fittings. If interior fittings from other suppliers are to be used, this must be definitely agreed with the manufacturer. 13 Temperature recorder (optional) • The recorder is used to record the temperature response over a certain period. This period can either be set to 7 days (preset) or 24 hours, as required. To change the setting, proceed as follows: raise the lever with the recording stylus and take the lock nut off the recorder axis. You can now remove the recorder disk. Now pull the recorder axis to remove the assembly from the housing. The switch with which to set the required time period is located on the side of the assembly. • The disks for the two time periods are different. Make sure that you insert the correct disk. • The clockwork for the recorder is powered by a 1.5V AA battery. This is located on the underside of the recorder assembly. ! • To replace the stylus, take the old stylus out of the stylus retainer and push the new one into the guides until it stops. Be careful not to touch the stylus with your fingers. • When re-assembling, make sure that the lock nut is sited correctly. RS485 Interface • The unit is equiped with an RS485 interface. You can use this interface to connect the unit to a PC or to network it to other refrigerating equipment. • For information about connection options and software, contact your local service centre. Cleaning • The refrigerator should be cleaned and if necessary disinfected before you use it for the first time and then at regular intervals thereafter. Fa n • When units are fitted with internal ventilation, it is vital that the interior fan is always in working order. Machine Compartment IMPORTANT: Before carrying out any maintenance or cleaning work in the machine compartment, always switch off the unit and remove the plug from the mains. 14 • Only use gentle cleaning agents. Never use aggressive or caustic cleaning agents, scouring powder, steel wool, abrasive sponges or chemical solvents. When cleaning, make sure that no fluids of any kind run into the ventilation housing. • Before restarting the unit after cleaning, the interior must be thoroughly dried. • To prevent warm outside air being sucked in unnecessarily when the door is open, the fan switches off when the door is opened. • The airflow to the fan must never be impeded. The ventilation slots must therefore never be blocked or covered. • The condenser/liquefier must be regularly dusted with the aid of a hand brush or a vacuum cleaner. This cleaning interval is set in the factory and is indicated by a “SERVICE” message on the display.
