ST700 GENERAL HANDBOOK
667/HB/27880/000 Page 74 Issue 8
These configurations are available on the IC4 CD. Other configurations may be
produced by Siemens Poole in order to meet the particular requirements of an area
or of one particular site.
These configurations need to be customised for particular installations using the
handset in a similar way to the T400 Pelican, using the information in the special
instructions of the configuration printout.
The commands to customise the ST700 are described in the Handset Handbook and
in the Special Instructions. These allow facilities such as kerbside and on-crossing
detectors and speed discrimination/assessment to be enabled or disabled. However,
the fundamental lamp sequence (i.e. flashing green-man, red-man or blackout
clearance periods) cannot be changed using the handset and is fixed in each of the
default configurations.
The configuration data for a stand-alone pedestrian crossing ST700 is loaded
through the handset port from a PC running IC4.
The configuration data could be loaded while the ST700 is still in the depot rather
than using a PC on the street. Provided the battery isolators are removed, the
configuration data will still be present in the battery backed-up RAM when the ST700
is installed.
The procedure for loading the configuration data is given in the Handset Handbook.
Once the configuration data has been loaded, ensure the Signals ON/OFF switch on
the manual panel is in the off position and connect a suitable handset to the 25-way
D-type connector on the ST700 CPU PCB.
With all signals covered (bagged), use the LMP handset command, which causes
each colour on each phase to illuminate in turn, whilst other persons are checking
the aspects. Care must be taken to ensure that any traffic on the junction does not
mis-read the signals and cause an accident. In addition, a visual check of the wiring
must be carried out, to ensure that the individual approaches are wired correctly as
shown in Figure 9.
The ST700 signals can now be switched on (using the switch on the manual panel)
and the ST700 powered up normally.
If the solar cell and signal dimming are not required then the following test can be
ignored.
1. Cover the photoelectric cell for at least one minute to exclude any light and
check that the signals are dimmed.
2. Remove the cover from the photoelectric cell and after at least one minute
the signals should revert to the bright condition.
