• In the event of a power failure, the red POWER FAIL LED flashes and an audi-
ble alarm sounds. The audible alarm can be muted for a certain period of time
(MUD parameter) by pressing the key.
• After a certain interval, the display switches off automatically. However, the
inside temperature can be displayed again by pressing the key.
• No parameters can be changed during a power failure.
• If, during a power failure, the inside temperature increases beyond the upper alarm point, the tempe-
rature alarm is displayed and the corresponding values are stored in the Alarm History.
• An alarm caused by a power failure is not signalled by the external alarm function. Should this be
necessary, this function can be added later. Please contact your service centre for this.
POWER FAILURE
• In the event of a power failure, an integrated rechargeable battery monitors the electronics for a maxi-
mum of 48 hours.
• This battery is recharged automatically when the unit is connected.
• If the charge in the battery is insufficient to allow monitoring, the BAT LOW error message appears in
the display.
• A BAT FAIL error message indicates that the battery is either defective or connected incorrectly.
• The battery should be replaced every 2 years as a precaution. This replacement should only be car-
ried out by a recognised service engineer. The unit must be dead before the battery is removed.
• The rechargeable battery is a lead accumulator which, if defective, must be disposed of separately.
RECHARGEABLE BATTERY
• With GOLD Safety Standard units, briefly pressing the key switches the
light in the refrigerator on or off. If the light is not turned off using the switch,
it goes out after a certain period of time.
• With SILVER Safety Standard units, there is a separate light switch in the con-
trol grid for turning the lighting (option) on and off.
• Pressing the key for 5 seconds starts an LED test. All the LEDs and all the segments of the display
are switched on briefly one after the other.
• In the event of a power failure, the display is switched on with the key (see the Power Failure sec-
tion). In this case, any available interior lighting is not switched on.
LED TEST / LIGHT
• Sustained pressing of the alarm test keys or causes the electronics
to simulate a rising or falling temperature. This tests that the alarm is working
properly.
• The temperature gets as close as 0.5° to the relevant alarm point and then
increases or decreases in increments of 0.1° until it reaches the preset alarm
point. The alarm LED flashes, the audible alarm sounds and the inside tempe-
rature display flashes.
• When the alarm test key is released, the temperature display returns to its original value and the alarm
ceases.
• During this alarm test phase, both the Alarm History function and any connected remote alarm are dis-
armed.
