ECKELMANN Case Controller UA 4 E Series, Инструкция по эксплуатации

Страница: 100 / 466

Firmware V3.13 21.04.2021 100/466
Controller type UA 121 E
The fan stops for an adjustable time (night blind run time). The fan restarts when toggling back from the
alternative to the standard setpoints.
Night blind run time
Controller types UA 141 E, UR 141 TE, UR 141 NE
5.11.2 Manual shutdown
A voltage present at the 230 V AC input for the manual shutdown switches off all control functions (cooling,
defrost,...) and the alarming (e.g. Registration of external alarms ), for details see Terminal assignment of the
230 V AC digital inputs . However all interfaces and operating functions remain active. The status of the digital
input is shown via the parameter "Status Man. ON/OFF" (menu 1-2).
All controller types
5.11.3 Automatic on/off
Controller type: UA 141 E only
The counter can be switched on and off via a voltage impulse (using a button installed on site, min. 6 seconds)
applied at the 230 V AC digital input for the counter shutdown. As with manual shutdown, all controlled
functions are switched off. The function of the digital input can be configured via the parameter Inv. D3 (i.e. Inv.
D2) in menu 6-2-4. In addition, external consumers can be switched on and off via an external relay at the
transistor output (terminals 91/92/93).
ATTENTION
As a rule, night blinds are closed on refrigerated multidecks when toggling setpoints. Some cases
require the fans to be stopped while the blind is being closed to prevent it from being forced out of the
case.

Setpoint toggle can be activated via Digital Input 2 (Terminal D21/D22, factory setting). This requires
Input 2 to be set as SETP.TOGGLE. The external setpoint toggle function is then available.
Alternatively, with an appropriate parameterisation of the digital inputs (menu 6-2-4), the setpoint
switch can be carried out via digital input 1 (terminals D11/D12) or digital input 4 (terminals D41/D42).
The function of the digital inputs can be configured via the parameters Inv. D1 to Inv. D4 (menu 6-2-4).
If more than one input has been parameterised with the same function, then this function is active as
soon as a signal is applied to one of these inputs.

DANGER
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 MANUAL OFF. (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
MANUAL OFF.Z1 or MANUAL OFF.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.
