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.

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).
