ECKELMANN UA 410 D, Руководство по эксплуатации

Страница: 31 / 142

Function of UA 410 D
23 Firmware V1.40 - Doku 2.1 06. April 2016
In order to ensure compatibility with the coldroom controllers of the UA 400
it must be taken into account that there is no heating circuit/reverse circuit with the UR 141.
4.2.2.10 Continuous running monitoring
Controller type: UA 111 X and UA 111 XP
Continuous running of refrigerated cases, e.g. in aggravated ambient conditions, has negative effects especially
with multidecks. It results in icing of the evaporator and reduced air curtain cooling. Run time limiting provides
for automatic forced shutdown of cooling as a means of preventing icing. As a result, the duration of cooling at
any one time is limited.
Duration of forced shutdown is adjustable. Commencement of forced shutdown is predefined. When necessary,
forced shutdown always takes place 1.5 hours after commencement of defrosting and after each additional
hour.
The following condition also applies:
If both compressors have been shut down, continuous run monitoring is deactivated in this zone for one cycle
(1.5 or 1 h).
When forced shutdown is active, it will be terminated before the set duration elapses if temperature
rises 4K on supply air sensor.
4.2.2.11 Two temperature zones
Controller type: UA 111 X and UA 111 XP
The controller allows of controlling one refrigerated display case in single-zone operation (maximum eight add-
on cases/supply air sensors) or two refrigerated display cases with two temperature zones and maximum seven
add-on cases/supply air sensors in the first zone and one case in the second zone.
The second zone in two-zone operation always refers to the 8th corpus, i.e. R2.8 and R4.8 must be used for
this.
Controller type: UR 141
With coldrooms, a LT coldroom is always controlled with the first zone and a NT coldroom is always controlled
with the second zone.
CAN bus disabling of refrigeration points by the compressor pack controller is not available on the
UA 410 D.
