Power Supply - Expert Information

A short user's guide to the hp supply.
A bug fix for the Gossen supply (1997 setup).

Use of memories is for the 1997 setup, be aware of changed voltages and current limits!

	   7	4 repeater cards - readout, hybrids, on		0.4A; 2.85A; 7.5A; 7.5A; 0.02A

		

	Make sure that all modules are in LOCAL state!				
	  (Otherwise a command will act only on the modules which are local.)	
	   If in doubt, press SUBADDR and increase the module number by pressing the CURSOR UP key.


	If for any subadress the Rmt Indicator in the display is On press LOCAL.
	If to operate all modules at once press SHIFT followed by COMMAND ALL.				
	  (Otherwise a command will act only on the module which subaddress is displayed.)	
	If to work with predefined settings use the recall command:
		Press * followed by R (for RCL) and the memory number.	The modules
		will be preset and their outputs switched on or off according to the stored
		settings; normally a single module but all of them when COMMAND ALL is
		activated before.
	For individual settings use the following commands:				
	   Switch Off			O (for Outputs)  O (for Off)		
	   Switch On			O (for Outputs)  O (for Off) and CURSOR DOWN (for On)		
	   Change Subaddress		Subaddr and CURSOR UP or CURSOR DOWN		
	   Set Voltage			V (for Voltage) and Number Keys and ENTER		
	   Set Current Limit		C and CURSOR DOWN (for Current) and Number Keys and ENTER		
	   Terminate w/o execution			ESC	
	If an error condition occurred (Overvoltage, Overcurrent...) the Prot flag is set on the appropriate				
	module - see front panel indicator.				
	   Reset Protection		SHIFT  and PROT CLEAR		

BST Pad Power Supply Malfunction after Power Cut in Trailer. 
------------------------------------------------------------


After a mains power cut the BST GOSSEN Power Supply which 
powers the 1997 extension of the pad detector is left in a 
non-programmed state. 
This results in immediate POWER ALARM when trying to switch 
the Pad detectors ready and is visualized by lots of red- 
background voltage and current readings in the 'Supply Voltages' 
subpanel.

There's only a manual fix so far which requires a minimum 
of skill. Please follow exactly this procedure (but refrain 
from trying if you feel you are not the right person...):

* Move to the trailer, first floor, aisle B in front of the 
  last rack to the right. The GOSSEN supply stands upright on
  the floor close to the wall of the trailer with front panel
  towards rack B10. 
* Turn this device face-up, so that you can operate the 
  buttons on its controller module. 
* Watch the four coloured LEDs on the right, namely the second
  yellow one which indicates that the supply is remotely
  ADDRessed. 
* When it has flashed once again be fast to do the following: 
- Push button 'CE/LOCAL'. The topmost yellow LED will turn off. 
- Push the black (!) down-arrow button several times until
  the text SETGROUP______ appears in the fourth line of the 
  display. 
- Push one after the other the buttons 1,2,4,5 and 7 of the 
  keypad. 
- Finish with the red ENTER button.

* Turn the GOSSEN device face-right again and move back to 
  the BST control Mac.

Now you should be able to switch the BST Pads to READY and ON 
without harm. 
Congratulations and thanks for your assistance!
