Siemens SIPART PS2 Operating Instructions Manual page 103

The positioner reports the "Configuration" mode with a configurable fault message. A position
feedback or display of limits A1 and A2 is not possible.
Note
Failure of electrical auxiliary power
If electrical auxiliary power supply fails when configuring, the positioner responds as follows
when the power supply is reestablished:
● The positioner switches to the first parameter.
● Settings of the values already configured are retained.
In order to save the changed parameter values, exit the "Configuration" mode or switch to
another parameter. When "Configuration" mode is restarted, the output in the display switches
to the last activated parameter.
Manual mode (MAN)
In this mode, you move the actuator with
irrespective of the setpoint current and leakages, if any.
Note
Accelerating the actuator movement
Proceed as follows if you wish to accelerate the actuator movement:
1. Keep one of the two direction buttons pressed.
2. Press the remaining direction button simultaneously.
Note
Failure of power supply
When the power supply is reestablished after a failure, the positioner switches to the
"Automatic" mode.
Automatic (AUT)
Automatic is the standard mode. In this mode, the positioner compares the setpoint position
with the actual position. The positioner moves the actuator until the control deviation reaches
the configurable deadband. An error message is displayed if the deadband cannot be reached.
Diagnostics
Proceed as follows to call the "Diagnostics" mode from the "Automatic" or "Manual" modes:
Press the three buttons of the positioner at the same time for at least 2 seconds.
