Blease Test Procedure 

 

 

Title:  B.A.V. POWER SUPPLY PCB 

DocumentNo:129TP076 

Sheet 2 of  5 

 

 

 

4.0  TEST DETAILS

 

4.1    Equipment

 

 

 

1.  TJ 70 - Blease test jig  (The jigs are serialised TJ 70A, TJ 70B, etc) 

 

 

2.  Variable DC power supply, 17-30 Vdc @ 2.5 Amp. The supply must have an adjustable  

 

 

 

current limit of 100 mA to 2.5 Amps. 

 

 

3.  Pair of short 4mm plug to plug leads for external DC supply to jig connection. 

 

 

4.  Miscellaneous short connection leads for attachment of test BAV supply board to jig (6 off). 

 

 

 

These will vary according to the issue of board tested.

 

4.2  Connections and Set up 

 

 

Connections for the test set up are shown below. (Not to scale)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

4.3  Top Charge

 

 

 

The 'Top Charge' switch on the jig only functions when the 'simulated' battery is selected.  

 

 

A passive circuit is used that kicks the board charger into continuous top charge mode as the  

 

 

switch is toggled down. It causes an increase in the charger load and also a temporary drop in  

 

voltage in the battery simulated. 

 

 

If this does not work, the switch needs to be returned to the up position for a few seconds    

 

 

before toggling it back down again. If this still does not work, there may be a problem with the 

 

 

battery charger on the board under test.
