Transducer Block Parameters Description
Bit 12 CW not asserted but relay drive transistor asserted in
error
Bit 13 CW asserted but relay contact not closed
Bit 14 CW asserted but relay drive transistor failed
Bit 15 Stuck relay contacts
COMM_LOSS The User configurable action of the actuator when network
communication is interrupted
Subparameter ACTION The user configurable action that actuator should take when
network communication is interrupted. Value 1=None, 2=Stop,
4=Close, 8=Open and 16=Position.
Subparameter
TARGET_POSITION
User configurable target position to which the actuator should
move the valve when network communication is interrupted.
Subparameter DELAY User configurable amount of time delay (0-60 seconds) before
communication loss is flagged.
ESD Emergency shutdown signal may be applied to the actuator to
move the valve to a predetermined user-configured shutdown
position, overriding existing control signals.
Subparameter
OVERRIDE_SETTINGS
Override settings for ESD.
Bit 00 to Bit 06 Not used
Bit 07 Network ESD - Value 1=ESD overrides network ESD,
0=Network ESD overrides ESD
Bit 08 Two speed - Value 1=ESD overrides two speed, 0=Two
speed overrides ESD
Bit 09 Thermostat - Value 1=ESD overrides thermostat,
0=Thermostat overrides ESD
Bit 10 Over torque - Value 1=ESD overrides over torque, 0=Over
torque overrides ESD
Bit 11 Lost phase - Value 1=ESD overrides lost phase, 0=Lost
phase overrides ESD
Bit 12 Jam - Value 1=ESD overrides jam, 0=Jam overrides ESD
Bit 13 Stop - Value 1=ESD overrides stop, 0=stop overrides
ESD
Bit 14 Local command - value 1=ESD overrides local command,
0=Local command overrides ESD
Bit 15 Inhibit - Value 1=ESD overrides inhibit, 0=Inhibit over-
rides ESD
Subparameter ACTION Predetermined user-configured emergency shutdown action.
