Troubleshooting and Maintenance Manual (AADvance

Controller)

When a fault exists on a channel, the module will report safe values for that channel and the

Discrepancy status variable reports TRUE.

Simplex Module Configuration

When a simplex module channel fault exists for longer than the module PST the channel indicates a

fault condition and the following status values are reported:

 Channel State = 7

 Channel Input State = FALSE

 Line fault = TRUE

 Discrepancy = TRUE

 Channel fault = TRUE

 Channel reports a voltage value = 0

Dual Module Configuration

When the reported values between modules in digital/analogue modules of a dual configurations

diverge by more than twice the safety margin specification for a period of two application scans, that is

by the following values:

 Digital input modules diverge by more than 2.0V dc

 Analogue input modules diverge by 400µA.

the lower of the two values will be reported and a discrepancy flag is set and the configuration

degrades to a simplex operation.

Triple Module Configuration

When the reported values between modules in digital/analogue triple configuration diverge by more

than twice the safety margin specification for a period of two application scans, that is by the following

values:

 Digital input module by more than 2.0V dc

 Analogue input module by 400µA.

the lower of the two values will be reported and a discrepancy flag is set and the configuration

degrades to a dual operation.

Output Channel Shutdown

In shutdown mode the output module drives its outputs to their configured shutdown settings; for

example, de-energized or hold last state. The shutdown mode and channel drive states remain in place

until new command states are received from a running application, or until the module loses power.
