ST700 GENERAL HANDBOOK
667/HB/27880/000 Page 75 Issue 8
If detectors are installed then they should be set up as defined in the Detector
Information Handbook.
Set up the date and time.
Check that the Lamp Monitor has correctly learnt all the lamp loads, using the KML
and KEL handset commands, described in the Controller Handset Handbook.
Check that there are no unexplained errors in the fault log.
This completes the testing and the site should be ready for Customer acceptance.
5.17 ST700 START-UP SEQUENCE
When the ST700 is initially powered up, it performs various internal checks before
starting normal operation. While these checks are being performed the green
heartbeat LED flickers and the red system error LED remains on.
If these tests fail then there is a serious fault on the CPU PCB and the PCB should
be replaced. The error message is repeatedly written to the handset display at 1200
baud, and no other handset operations can take place:
for RAM read/write test fail
for RAM read/write test fail (Dual Port RAM)
for CPU and RTC crystal check fail
In addition to the above internal checks, the ST700 goes on to check the contents of
its battery backed RAM, e.g. the fault log and checksum on the timings data, before
attempting to switch on the signals.
Once the ST700 is running normally, it extinguishes the red system error LED and
the green heartbeat LED flashes.
If the red system error LED remains illuminated then a handset should be connected
and the fault log checked to see what errors exist. The fault log is described in the
Handset Handbook.
5.18 REFITTING THE LID
Reconnect the earth lead by fitting the Faston connector to the Faston Tag. Replace
the Lid carefully on the equipment mounting frame and secure the Lid to the frame
using the „T‟ key.
