Rittal enclosure cooling unit

7 Operation
EN
If an alarm tolerance level of "medium" is selected, the
system will tolerate an impairment to the air throughput
in the external circuit of approximately 35% before the
system message "Change filter" appears in the display.
The following diagram illustrates the development of
cooling output depending on the air throughput in the
external circuit and the alarm limit (fig. 55).

Sample cooling output development
Optical fibre
Here, it is possible to set the colour of the optical fibre in
the device's normal state. Choose between white (fac-
tory setting), pink, green and blue or deactivate the op-
tical fibre in normal status.
Change the device PIN
Here, you can change the default device PIN from "22"
to any value between "00" and "99".
"Rittal Smart Service" and "IoT Interface"
In the "Configuration" zone, as well as the device config-
uration itself, you can also configure the connection to
the Rittal Smart Service or retrieve IP information from a
connected IoT interface.

Technical Guide
Basic operating data as well as the current status of the
cooling unit can be viewed in the "Technical Guide"
zone.
Operating data
– Average energy efficiency ration (EER) for the last 24
operating hours.
– Minimum and maximum internal temperature of the
last 24 operating hours.
Software
Here, you will find information on the software version
being used as well as the date of the most recent update
and whether there is a current update available.
System messages
While the 7-segment display only shows a system code,
current system messages can be viewed here in plain
language, together with troubleshooting measures and
solutions, where applicable.
You can also view a message history listing all messages
since the device's last restart. For all messages occur-
ring prior to the most recent restart, the number of oper-
ating hours at the time of the message is given.
7.5.4
Product informationen
The "product information" zone contains basic informa-
tion about your cooling unit, such as the item number,
serial number etc. It also offers direct access to the avail-
able accessories.
7.5.5
Services and spare parts
The "Services and spare parts" zone is a quick and easy
option for ordering spare parts for your cooling unit.
7.5.6
Fast Copy
The "Fast Copy" function allows you to copy the entire
configuration of a cooling unit to unlimited other cooling
units. This function can be found under Product Man-
agement, where all scanned items can be organised in
the form of lists and retrieved.
Note:
The more the air throughput in the external
circuit is impaired, the lower the maximum
cooling output and energy efficiency of the
cooling unit will be.
Note:
– If filter mat monitoring is deactivated ("De-
activate" level), it is still possible to select a
filter tolerance level. If the threshold is ex-
ceeded, the system code "A21" will appear
in the display instead of "A03".
– If filter mat monitoring is deactivated and no
filter tolerance level is selected, no system
message will be output.
Note:
To change the device PIN again, you will first
need to enter the currently stored device PIN.
