ST800 Guidance Notes

Page 2 667/HB/27000/100 Issue 1

Introduction

The following pages summarize how to use the new ST800 traffic controller from

Siemens. It assumes knowledge of the T400 and therefore concentrates on the

differences between the two types of controller.

Following these pages is a blank Fault Report form. We would be grateful if you

could complete a copy of this form and fax it back to Poole when you first install the

ST800 controller and after any subsequent visit you make to the site. This will allow

us to compile a history of each controller to help diagnose any problems which may

occur.

For more information, and if you have any problems, do not hesitate to contact me,

Paul Cox, on Poole (01202) 782621.

The T400 was limited to 16 phases, 4 phases per card, whereas the ST800 lamp

switch cards provide 8 phases each, giving a total of 32, with the first 26 phases

labelled ‘A’ to ‘Z’ leaving the last six labelled ‘A2’ to ‘F2’.

Initialization

We strongly suggest that the controller’s ‘Self Test’ facility is used before the

controller is powered up normally for the first time. Details of how to use the self test

facility are described later in this document.

When an ST800 controller is switched on for the first time, it will log a fault and not

illuminate the signals without operator intervention. Within this document there is a

complete list of all the faults reported by the ST800.

It will power-up logging memory faults and ‘New Firmware’ since the contents of

RAM are corrupt, i.e. are not what the processor is expecting. These faults can be

cleared in the usual way by typing ‘RFL=1↵’ and switching the power off and back

on. The clock will also need to be set-up and this is also described in this document.

Note that the initialization commands (TKE, etc.) are only required to initialize the

controller after its configuration PROM has been changed. These commands will

have no effect at any other time, i.e. they can no longer be used to re-initialize a

controller which is working normally. Also note that these commands will be rejected

with a ‘*L’ error if the signals on/off switch on the manual panel is still in the ‘on’

position. Therefore...

Do not change any timings or other settings on the

controller on the assumption that they can all be reset back

to the PROM settings by entering the initialisation

commands.

This document also contains information on the LED’s on the front of the main

processor card and the connectors on the back of the power distribution units, the

lamp switch cards and the main processor card.
