Warning! 

The following tests will result in the signals extinguishing

 

 

  Test  the  300mA  RCD  (if  fitted)  by  pressing  the  test  button.  The  breaker  should 

operate immediately. If the contract specifies the testing of RCD speed, then this 
test  should  be  performed  using  the  appropriate  equipment.    If  the  RCD  is  faulty 
then the results should be recorded the unit replaced.  Any replacement unit is to 
be similarly tested to ensure correct operation before leaving site. 

 

  Check  the  termination  panel(s)  and  master  switch  panel  within  the  Cabinet  and 

ensure  that  there  are  no  loose  fixings,  or  damage  to  these  panels.  Tighten  any 
loose fixings and carry out any repairs that are necessary. 

 

  Check  the  logic  assembly  and  other  assemblies  within  the  ST750  are  securely 

fixed. Retighten loose fixings as necessary. 

 

  Check that all fuses are secure in their holders.. 

 

Warning! 

It  is  strongly  recommended  that  the  ST750  supply  is  isolated 
before any fuses are checked 

 

  Check  wiring  and  cableforms,  particularly  ribbon  cables  for  damage.  Replace or 

re-route as appropriate. 

 

  The  battery  on  the  ST750  CPU  PCB  must  be  replaced  if  it  has  failed.  Any 

replacement  battery  should  be  suitably  marked  with  an  appropriate  date  label. 
Having done this, the ST750 records should be updated accordingly. 

 
The following tests require the ST750 to be powered and running normally. 
 

  Tests of the Voltage Drop of Neutral Conductors. This test should be carried out 

during each periodic/annual inspection as a simple check of neutral cables, which 
can also provide a good indication of the state of the intersection cabling. 

 

(i)  Take a digital multi-meter or voltmeter and set it to measure 240 volts AC 

(RMS). 

 
(ii)  Select  a  phase  and  wait  until  its  green  has  just  terminated.  Measure  the 

voltage  between  the  Cabinet  Assembly  neutral  and  the  green  feed;  the 
voltage  should  be  no  greater  than  4  volts  (RMS)  throughout  the  signal 
cycle,  except  when  the  phase  next  goes  to  green.  If  the  voltage  between 
the green feed and neutral is greater than 4 volts then do the following: 
 
(1) Check  all  joints  in  the  appropriate  neutral  cable  run,  ensure  that  they 

are all tight and none are seriously corroded, replace or tighten them as 
necessary.
