Storage compartment for service counters
(controller type UA 141 E)
The
Inverted Defrost
relay (terminals 63/64, function reversed) can be used, for example, to interrupt the
cooling of a storage compartment. The relay contact is closed when the cooling is running. The relay contact is
opened when the defrost is switched on:
If the controller switches on the defrost, the relay contact is opened.
If the controller switches off the defrost, the relay contact is closed.
The interruption of the cooling during the defrost is always during the safe defrost time for the storage
compartments. It may therefore take longer than defrosting in the 1st or 2nd temperature zone. In addition, this
relay is not switched on until the wait time has elapsed.
Manual defrost (not for UA 131 E in master/slave mode)
For a manual defrost (e.g. for service purposes), a defrost can be initiated via the system centre / store
computer / operator terminal, as follows:
Select Remote Control - Case Controller (or CAN bus address) - 3 Timer - 2 Defrost Timer and in the line
man. Abtauung
set it to ON, or
via the host computer (see LDSWin operating manual).
Automatic initiation of the defrost during first start
A defrost is automatically started during first start for the following controller types:
UA 121 E, UA 131 E, UA 141 E
discharge gas defrosting (hotgas defrosting)
, the 2nd defrost stage must not be
parametrised otherwise the 2nd defrost relay is not activated, as is generally desired with discharge
gas defrosting.
If any defrost (internal controller function or via LDSWin) is initiated and ended or prevented by the
conditions
Defrost on demand
/
End via evaporator sensor
, the complete safe defrost time must
have elapsed first until any manual defrost can be initiated again. If any further manual defrost
should be initiated immediately, the previous one
must
be ended first:
Internal controller function:
Menu 5 Remote control - select case controller (CAN bus address) -
3 Clock - 2 Defrost timer, set parameter "man. Abtauung" (menu 3-2) to OFF.
LDSWin:
click on "End defrost" button. The manual defrost can then be initiated again immediately.
