Installation and Setup

Use of the Fail signal to start an external device and maintain

synchronization depends on the device having completed its

previous run and being in a state from which a blank run can be

started. Using a non-zero Cycle Time will mean that, because the

ATD/TD starts the next tube before the external device has finished

the current run, synchronization will not be maintained; a Fail signal

issued by the ATD/TD will not be accepted by the external device

and synchronization will be lost.

Start Signal

NOTE: The data handling system has to be ready by the time tube

desorption has finished the Fail Output Signal process and

it should not be used when the tube desorption occurs

before the previous run has finished.Otherwise a tube

failure will cause the following tube to be desorbed and the

sample kept waiting until the “dummy” data handling run

initiated by the Fail Output Signal had finished.

NOTE: Depending on the configuration of the external

instrumentation, it may be more appropriate to connect the

Fail signal elsewhere, e.g., to a data handling system.

CAUTION

Do not use the Fail signal to maintain synchronization

whenever a non-zero cycle time is used.
