RK3000 High Frequency Power Supply
Operating Manual
Page 23 of 73
In addition to the keys on the keypad, an ON/OFF or push button switch on the control
cabinet is provided. This switch is used to energize and de-energize the control
components and in turn the power to the Transformer Rectifier.To de-energize the power
to the cabinet control circuits, the breaker must be opened.
When the ON/OFF or push button switch is OFF, and the breaker is closed, the Electrical
Reading Display will show zeros for all electrical readings and the mode area will show
the message “Stop”.
In this OFF condition, all the programmable parameters may be viewed in their
appropriate screen (or changed with the proper security code) without energizing the
associated transformer-rectifier (T/R).
Note: BEFORE ENERGIZING THE CONTROL FOR
THE FIRST TIME, THE “MAX SET
SIZE” VALUES MUST BE PROGRAMMED. IF THIS IS NOT DONE THE CONTROL
WILL NOT ENERGIZE
When the breaker is closed and the STOP/START switch is placed in the START
position, there is a one second delay between the energizing of the contactor and firing of
the IGBTs. When the IGBTs are fired they are done slowly so there is no inrush on the
control electrical feeders or substation. Power is applied to its associated transformer
until either sparking or arcing occurs, or an electrical limit has been reached. If no
sparking or arcing is occurring, the display will be similar to the one below.
No Sparking Present
If sparking or arcing is occurring, the display will be similar to the screen below.
