5. Function block actual mode does not
change with target mode.
5.a Resource block actual mode is Out of Service. 5.a Change Resource block target mode to Auto (see
page 150, Resource Block Mode, or host system
documentation).
5.b Transducer block actual mode is not Auto. 5.b Change transducer block target mode to Auto (see
page 157, Transducer Block Mode or host system
documentation).
5.c Schedules that define when function blocks execute
are not set correctly.
5.c Set the schedules using host system or
configuration tool. All function blocks must be in a
schedule that is downloaded to the device.
5.d Configuration error 5.d Look for configuration error bit in BLOCK_ERR. By
default, all enumerature type parameters are initialized
to 0 (undefined). They must be configured before the
block can be put into service.
6. Input or Output Block does not go to
mode target
6.a Resource block actual mode is Out of Service 6.a Change Resource block target mode to Auto (see
page 150, Resource Block Mode, or host system
documentation).
6.b Transducer block actual mode is not Auto. 6.b Change transducer block target mode to Auto (see
page 157, Transducer Block Mode or host system
documentation).
6.c Transducer has detected a hardware failure. 6.c See transducer section of Detailed Setup for repair
information.
6.d Schedules that define when function blocks execute
are not set correctly.
6.d Set the schedules using host system or
configuration tool. All function blocks must be in a
schedule that is downloaded to the device.
6.e Configuration error. 6.e Look for configuration error bit in BLOCK_ERR. By
default, all enumerature type parameters are initialized
to 0 (undefined). They must be configured before the
block can be put into service.
7. Block dynamic parameters do not
update
7.a Block actual mode is Out of Service 7.a Change the block target mode to an operational
mode (see F
OUNDATION fieldbus Communication,
Appendix C and host system documentation).
8. OUT is not being automatically
updated from the AI block.
8.a Transducer block mode in not Auto. 8.a Change transducer block mode to Auto.
8.b AI block is not scheduled 8.b Schedule the AI block.
9. Transducer block setpoint
Setpoint(D) (SETPOINT_D [32]) is not
being automatically updated from the
DO block.
9.a Transducer block mode is not Auto. 9.a Change transducer block mode to Auto.
9.b DO block is not active. 8.b Change Outblock Selection to DO Control.
10. Instrument will not calibrate.
10.a Configuration errors. 10.a Verify configuration.
10.b Lever Assembly is locked 10.b Check the Lever Assembly lock and unlock.
10.c Lever Assembly is not clamped to the torque tube. 10.c Clamp the Lever Assembly to the torque tube.
10.d Device setup doesn't match real device conditions. 10.d Adjust settings to match device conditions and
setup.
11. Field Communicator does not turn
on.
11.a Battery pack not charged. 11.a Charge battery pack.
Note: Battery pack can be charged while attached to the
