2.3.12
Initial commission
For the first start-up after installation of the cabinet, the following procedures have to be executed:
•
Confirm that the connection cables to be used are of a satisfactory cross section!
•
Check if the factory settings of set values, safety and monitoring functions and communication are suitable for
your intended application of the device and adjust them if required, as described in the manual!
•
Before using remote control via PC, read the additional documentation for interfaces and software!
•
Before using remote control via the analog interface, read the section in this manual concerning analog interfaces!
During every boot phase, the master unit will show a language selection. The default language
English
can be
changed here or later in the MENU, in the HMI Setup.
Every text below concerning display is related to language setting “English”.
2.3.13
Commission after a firmware update or a long period of non-use
In case of a firmware update, return of the equipment following repair or a location or configuration change, similar
measures should be taken to those of initial start up. Refer to
Only after successful checking of the device as listed may it be operated as usual.
2.3.14
Removing units
In case of a defect of a slave unit it’s possible for the cabinet to continue running with the remaining units. In or-
der to remove an unit for repair or to replace it, a certain procedure is required (see below). After that and when
powering the cabinet again, the master unit will automatically detect the altered configuration and present itself
accordingly in the display or to remote control software. With the standard configuration being temporarily unavail-
able, the rated current and power of the cabinet are reduced, as well as the device name will change according to
the product key as described in
Following steps are to perform to remove a slave unit:
1. Power off the cabinet with an external main switch or by switching off all units with their rotary mains switch
on the front.
2. For the unit going to be removed:
a. Remove the strain relief (strap) from the AC supply cable.
b. Loosen the fixture that fixes the AC input connector plug.
c. Remove the AC connector plug.
d. Remove the plug from connector “Share”. If master unit: remove plug from connector “Sense”, if being used.
e. Remove the patch cable or both, if unit’s in the middle, from the master-slave bus connectors. Later, for the
operation of the cabinet without the removed unit, the bus must be connected again from the upper to the
lower unit by using a longer cable.
f. If master unit: remove any other possibly connected cable from the digital or analog
g. Loosen the nuts/bolts on the DC input and remove them (2-6 pieces). Before doing so make sure that the
DC input doesn’t have dangerous voltage anymore, probably by checking it with a multimeter.
h. Remove the screws on the front (4x).
i. Carefully and slowly retract the unit from the cabinet.
2.3.15
Inserting units
The procedure of inserting units again is the same like when removing an unit, only vice versa. See steps described
in
. Before going to insert an unit make sure the cabinet is completely switched off or
better, disconnected from AC supply.
