High Current Switches
The high current switches can be switched on and off independently by the control buttons
under ‘Connector 2’. All switches can be disabled (i.e. switched into the non-conducting state)
be the ‘Disable Outputs’ button.
The high current switches can be shut down (i.e. set into the non-conducting state) by one or
both overload signals from the detector control blocks. The configuration is set by jumpers on
the DCC-100 board, see ‘Installation’, ‘Shutdown of High Current Switches’.
If the high current switches have been deactivated by detector overload they must be explicitly
switched on after the overload condition is removed.
Disable Output Function
The power supply outputs, the detector gain signals and the high current switches can be
disabled and enabled by the ‘Disable Output’ or ‘Enable Output’ button. You can
automatically disable all outputs at the start of the software to bring the system in a safe state
before you switch on the detectors. The ‘Disable on Start’ function can be switched on and off
under ‘Parameters’.
Cooler Control
The cooling current can be switched on and off by clicking on the ‘ON’ button. To control the
cooling power, you can set an output voltage and an output current. Of course, setting voltage
and current in an electrical circuit simultaneously is impossible. The cooling power supply
works in a way that the voltage at the output is controlled as long as the specified current is
not reached. When the specified current is reached current control takes over and the current is
controlled. In other words, the cooling is controlled in way that neither the selected voltage
nor the selected current is exceeded. Current control is indicated by the ‘Curr Lmt’ light.
Saving and Loading the Setup
To load or to save the DCC setup, click on
‘Main’ in the menu bar and select ‘Save’ or
‘Load’. The ‘Save’ and ‘Load’ menus are
shown below.
When you save a setup you first have to enter
a file name or to select a file name by
clicking into the ‘file name’ field. There you
can also change to other directories or drives.
A history of file names is available via the
‘
’ button right of the file name.
Then you can - but need not - type in the
operator name, a company name, and a
description for what your setup is.
