Positioner Temperature

The temperature inside the positioner is displayed on the first graph and in the “Temperature Value’ display box. An upper
and lower limit are set. When the temperature moves beyond these limits, a warning is generated. These limits corre-
spond with temperature capabilities of the positioner electronics.

Pilot Relay Response Time

The pilot relay response time is displayed on the graph and in the “Current Value” display box. This represents the time
(in milliseconds) for the pilot relay to respond to a command. Two limits are set and also adjustable. When the response
time grows beyond these limits, a warning is generated, then an alarm. To adjust the limits, use the page up/down but-
tons on your keyboard or use the mouse to click on and slide the limit indicators on the graph. Press the

Apply button at

the bottom of the screen to activate the new limits in the positioner.

Pilot Relay Cycles

The number of relay cycles is displayed on the graph and in the “Current Value” display box. It represents the number of
pilot relay cycles since factory reset, or since the

Counter Reset button was selected. Two limits are set and also adjust-

able. The lower limit is fixed at 90% of the upper limit. As the cycle counts pass the Initial Warning limit the Positioner
Health bar on the Dashboard will begin to turn yellow and a warning will be sent in response to a HART command 48. As
the cycle counts pass the Final Warning limit the valve health bar on the Dashboard will turn completely yellow. To adjust
the limits, use the page up/down buttons on your keyboard or use the mouse to click on and slide the alarm limit indica-
tor on the graph. Press the

Apply button at the bottom of the screen to activate the new limits in the positioner.

Pilot Relay Travel

The number of cycles is displayed on the graph and in the “Current Value” display box. It represents the travel of the relay
(in% full scale) since factory reset, or since the

Travel Reset button was selected. Two limits are set and also adjustable.

The lower limit is fixed at 90% of the upper limit. As the cycle counts pass the Initial Warning limit the Positioner Health
bar on the Dashboard will begin to turn yellow and a warning will be sent in response to a HART command 48. As the
cycle counts pass the Final Warning limit the valve health bar on the Dashboard will turn completely yellow. To adjust the
limits, use the page up/down buttons on your keyboard or use the mouse to click on and slide the alarm limit indicator on
the graph. Press the

Apply button at the bottom of the screen to activate the new limits in the positioner.

Binary Indicators

The status of diagnostic indicators is displayed at the bottom of this screen. These indicators also affect the health status
bars on the Dashboard. Select the

Implications and Possible Solutions buttons to view additional information about these

positioner indicators.

6.4 Actuator Health

This screen displays all of the indicators that determine the actuator health. For each indicator, an

Implications and Pos-

sible Solutions button is available. When the button is selected, information regarding that indicator will be displayed
on the right. This page is only available with the Advanced DTM used with a positioner that has been upgraded with Pro

diagnostics.
