Electronics verification of the Rosemount 8600D can be done by either utilizing the internal
signal simulation capability or by applying an external signal source to the “TEST FREQ IN”
and “GROUND” pins.
C.1 Safety messages
Instructions and procedures in this section may require special precautions to ensure the
safety of the personnel performing the operations. Refer to the following safety messages
before performing any operation in this section.
C.2 Electronics verification
Electronics functionality can be verified via two different verification methods:
 Flow Simulation Mode
 Using an External Frequency Generator
Both methods require the use of a Field Communicator or AMS. It is not required to
disconnect the sensor to perform the electronics verification since the transmitter is
capable of disconnecting the sensor signal at the input to the electronics. Should the user
Explosions could result in death or serious injury.
 Do not remove the transmitter cover in explosive atmospheres when the circuit is
alive.
 Before connecting a HART
®
-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
 Verify the operating atmosphere of the transmitter is consistent with the appropriate
hazardous locations certifications.
 Both transmitter covers must be fully engaged to meet explosion-proof
requirements.
Failure to follow these installation guidelines could result in death or serious injury.
 Make sure only qualified personnel perform the installation.
Remove power before removing the electronics housing.
