5.10 Manual shutdown
A voltage present at the 230 V input for the manual shutdown switches off all control functions (cooling,
defrost,...) and the alarming (e.g. Registration of external alarms ). However all interfaces and operating
functions remain active.
All controller types
5.11 Registration of external alarms (e.g. CO2 alarm)
A voltage applied at the 230 V AC input serves to register external alarms e.g. CO
2
alarms. The message text
(CO
2
alarm, factory setting) can be freely entered in menu 6-2-4 (also with the BT 300).
Warning about dangerous electrical voltage!
Danger of electric shock! BEFORE
connecting and disconnecting, it must be checkedthat no
voltage is present at the 230 V AC digital inputs! The controller and connected voltage carrying
components remain supplied with power!

The manual shutdown can be activated using all the digital inputs. The corresponding input must be
parametrised as
HANDABSCH (Menu 6-2-4) for this. The manual shutdown is not available until then.
A manual shutdown via the digital inputs can also be performed separately for zone 1 and zone 2. This
requires one digital input to be parametrised as HANDABSCH.Z1 or HANDABSCH.Z2 respectively.
The function of the two digital inputs can be configured via the parameters
Inv. D1 to Inv. D4 in menu
6-2-4. If multiple digital inputs should be configured with the same function, this function becomes
active as soon as a signal is applied to one of these inputs. The same 230 V input can also be used as
input for the pane heater or door contact for controller type UA 141 or UR 141 NK/TK. However, the
function “Manual Shutdown” is then no longer available.

Warning – hazardous electrical voltage! Danger of electric shock! BEFORE connecting and
disconnecting it must be checked that the 230 V AC digital inputs are off load! The controller and
connected voltage carrying components remain supplied with power!

The external alarm can be activated via digital input 4 (terminals D41/D42). If the digital input is used
for the monitoring of e.g. a CO2 alarm, then for safety reasons its function should be inverted to "ON"
via the parameter Inv. D4 (menu 6-2-4).
