Settings (continued)
Step2: Setting the unit type (password protected; has to be made for the universal type only).
Section 5.3.12 shows how to change the input voltage setting. Normally the input voltage setting
is done at the factory (as well as the setting of the transformers). If there is any need to change,
please use the User password first before entering the input voltage setup display. Without the
right password no changes are allowed.
A series of menus from which various customer-specific settings can be set up is available via the
converter display. The converter has been set up according to the specification at the factory, and
should not normally require any changes. In the event that changes are required, the set-up
menu can be displayed by pressing the down arrow and shift push buttons simultaneously (after
switching on the mains supply). The Menus and Sub-menus are described later in this section.
5.2.3
Converter Commissioning
WARNING!
A. Commissioning must be only carried out by trained personnel since work has to be done on
component that may be “live”!
B. Power up the device only when requested to do so in the following text.
ATTENTION:
I. Commissioning tasks should be carried out if:
•
the system is being put into service for the first time,
•
changes have been made, or
•
repairs were carried out.
II. Carry out the individual steps in the correct sequence:
1.
Switch off circuit breakers Q100 and Q001.
2.
Check the setting of the control voltage transformers and the output transformer. Since
the unit can be operated at different input voltages and frequencies every transformer
has to be set separately to the right tap (see Section 5.2.2).
3.
Switch on the mains power to supply the unit.
4.
Check for clockwise rotating field of the mains supply to terminals X1.1/2/3.
5.
Switch on circuit breaker Q100.
6.
Check the setting of the input voltage (see Section 5.3.12).
7.
Check the rest of the settings in the display. If necessary, make changes and store
these by means of the “setup“ menu (see later in this section).
8.
Carry out a lamp test by pressing the “Shift“ and “Reset“ push button simultaneously.
9.
Acknowledge any faults shown on the display by means of the “Reset“ push button.
10.
Switch on circuit breaker Q001
11.
Start the unit by pressing “Shift” and “ON” push buttons simultaneously. The LED’s for
input, static switch and rectifier change from yellow to green. The DC output LED is
illuminated yellow and will change to green after the start up ramp.
12.
Check the DC-output voltage at ter and -.
13.
Stop the unit by pressing “Shift” and “Off” push buttons simultaneously.
