Required Transmitter Configuration

WARNING

Upon transmitter startup or abnormal power reset, any external device controlled by a discrete output may be momentarily activated.

Upon transmitter startup or abnormal power reset, discrete output states are unknown. As a result, an external device controlled by a discrete output may receive current for a brief period.

When using Channel B as a discrete output:

•You can prevent current flow upon normal startup by setting Channel B polarity to active low.

•There is no programmatic method to prevent current flow for Channel B upon abnormal power reset. You must design the system so that a brief current flow to the external device controlled by Channel B cannot cause negative consequences.

When using Channel C as a discrete output, there is no programmatic method to prevent current flow upon either transmitter startup or abnormal power reset. You must design the system so that a brief current flow to the external device controlled by Channel C cannot cause negative consequences.
