Actuator
The status of each actuator can be viewed by clicking on the
icon on the Home page corresponding to that actuator. A
screen similar to that in Fig. 95 is displayed.
Fig. 95. Actuator Status.
For Modbus™ burner systems (when the Fuel/Air Control is
connected to the S7810M Modbus Module), some of this
information is not available: Key, Stop Type, Close Direction,
and State. This information is blank on the screen in this case.
When the Fuel/Air Ratio Control system is connected to a
S7999D Com port that has been configured for Fuel/Air Ratio
only (Commission), the State status indicates whether the
actuator has been configured (key, stop type, and close
direction has been set) or not by displaying “CONFIGURED”
for its state. If the actuator has been configured and also has
its endpoints locked, the state displays a “LOCKED” status.
Actuator fault history can be viewed by selecting the “Show
Faults” button (Fig. 96 and Fig. 97).

Diagnostic information about the actuator can be viewed by
selecting the “Diagnostics” button. Diagnostic data for all
actuators is displayed at the same time to give a quick
snapshot of all actuator activity. The data can be displayed in
degrees (Fig. 98) or in analog-to-digital counts (Fig. 99).
