The alarm system has been modified in accordance with your wishes to
operate in the following way.
1. Transmission Fault
Should the computer fail to reply due to either repeated faulty transmission
or failure of t e Dataphone or lines, the alarm will sound for a period
of about 6 seconds and the " Transmit, Fault" lamp will light. The
lamp will remain lit until the fault is cleared by pressing the "Reset
Logic" button. The lamp may also be extinguished by pressing the
"Fault Lamp Reset" button but this willleavethe logic in its faulty
condition.
2. Digitiser Input Fault
Should one of the basic counters fail due to a faulty input, the alarm
dill sound for about 6 seconds and the "Digitiser Input Fault" lamp
dill light. The lamp will remain lit until the counter in question is
reset, and the "Fault Lamp Reset" button is pressed. It should be
remembered that' there is also a fault lamp on the scales of the counter
which will indicate which of the four counters caused the fault.
Yours sincerely,
