ST700 GENERAL HANDBOOK
667/HB/27880/000 Page 73 Issue 8
links in the form of a handbag, with a handle to aid insertion and extraction. They fit
into PCB mounted sockets and use spring clips in the socket to make the connection
and fit. These spring clips also retain the link to the PCB; the contacts are gold
plated for low resistance and reliability.

5.16 ON-SITE ST700 TESTING
Connect a suitable handset to the 25-way D-type connector on the ST700 Phase
Drive PCB.
Replace each of the 4 off 10A fuses in the fuse holders F6 to F11 on the Phase
Drive PCB with 3.15A fuses, leaving the dummy fuses in place. See Figure 23 and
Figure 20 for details. This protects the individual circuits whilst the self-test is being
performed in the event of a short circuit in any of the cables.
Select and run the self-test – see section 7.
If the self test passes, replace the 10A fuses in the Phase Drive PCB.
The ST700P stand-alone pedestrian controllers normally run one of the standard
configurations generated by Siemens Poole that are listed below:
Stand-alone Pelican crossing with MCE0125 style flashing green man /
flashing vehicle amber.
Stand-alone crossing with a red clearance period, i.e. TR0141C near-
sided Puffin or Toucan crossing.
Stand-alone crossing with a blackout clearance period, i.e. TR0141C
far-sided Pedestrian, Puffin or Toucan crossing.
