Monitoring The Number Of Total Strokes "L._Strk - Siemens 6DR50 Series Operating Instructions Manual

Parameterizing/addressing
9.4 Description of parameters
J3.LEVL2 - threshold 2
Use this sub-parameter to set a threshold in "°C" or "°F". Use threshold 2 to monitor the high
limit temperature. Set the threshold in a range from "-40.0C" to "90.0C" or "-40.0F" to
"194.0F".
The positioner triggers a fault message if the current temperature inside the enclosure
exceeds threshold 2. The procedure to activate and display this error message is described
in the "XDIAG" parameter.
The factory setting is "80.0C".
J4.LEVL3 - threshold 3
Use this sub-parameter to set a threshold in "°C" or "°F". Use threshold 3 to monitor the high
limit temperature. Set the threshold in a range from "-40.0C" to "90.0C" or "-40.0F" to
"194.0F".
The positioner triggers a fault message if the current temperature inside the enclosure
exceeds threshold 3. The procedure to activate and display this error message is described
in the "XDIAG" parameter.
The factory setting is "90.0C".

Monitoring the number of total strokes "L._STRK"

L. STRK - Monitoring the number of total strokes
Use this parameter to continuously monitor the total strokes covered by the actuator. A total
stroke corresponds to the path from the lower endstop of the actuator to the upper endstop
and back again, in other words twice the travel. During operation, partial strokes of the
actuator are added together into total strokes.
Configure the following settings to activate the function:
1. Set the "L. STRK" parameter to "On". Sub-parameters are displayed. Monitoring is
activated.
2. Set the suitable values in sub-parameters. The setting options available in sub-
parameters are described below.
The current value is displayed in Diagnostics parameter '1.STRKS' Number of total strokes
(Page 209). The positioner triggers an error message if the current value exceeds a limit
threshold.
The factory setting is "OFF".
L1.LIMIT - Limit for number of total strokes
Use this sub-parameter to set the base limit for the number of total strokes. Set the base limit
in a range from "1" to "1.00E8".
The factory setting is "1.00E6".
