Manual

™
APEX and APEX Sentry
Whenever sending or requesting data that would disrupt the loop or change
the output of the transmitter, set the process application loop to manual. The
HART Communicator will prompt you to set the loop to manual when
necessary. Acknowledging this prompt does not set the loop to manual. The
prompt is only a reminder; set the loop to manual as a separate operation.
Bench Hook-up
Connect the bench equipment, and turn on the HART Communicator by
pressing the ON/OFF key. The HART Communicator will search for a
HART-compatible device and indicate when the connection is made. If the
HART Communicator fail to connect, it indicates that no device was found. If
this occurs, refer to Section 5: Hardware and Software Maintenance and
Troubleshooting.
Field Hook-up
Signal point may be grounded at any point or left ungrounded.
