Menu 7: Pneumatic Output for Troubleshooting
M 1 2 3 4
½ ½ - - ½ M, LED 1 and LED 4 flash
Serves to check the pneumatic parts of the positioner by directly applying
current to the IP module (no control; software limit values such as “stoke
limits” or “tight closing” are ignored).
The current of the IP module is increased by about 3% in 32 steps.
By measuring the output pressure generally the following characteristic line
of the IP module is achieved. The ramp also may be more steep or flat
depending on the air supply pressure.
The pneumatic works precisely, if the actuator begins movement in section
II and runs latest in section IV into the end position.
If no reaction is shown, check:
- does air supply exist? - is plug connected to IP module?
If these items are okay, possibly the electronics or a pneumatic part is
defect.
After leaving this menu (by pressing the
( ) or ( ) key) the actual setpoint
is automatically restarted.

For the purpose of checking the control reaction of the actuator to a set-
point jump can be observed via the indicator. As far as the device is IN
SERVICE the
(+)(–) keys can initiate jumps of 12.5 % (or 1 %) each. The
starting value for Menu 8 is always the current setpoint value.
If the control behavior is to be improved, this can be reached by performing
a complete Autostart (see Menu 2) or through manual tuning (see Menu 6).
After leaving this menu the existing setpoint value at the input is automati-
cally restarted.
This menu point can also be called up under normal operating conditions,
by twice pressing of key
( ).
8.3 Do PST
With this function, the Partial Stroke Test is started, with the given para-
meters by DTM. If the test is passed back to the menu.
If the PST is not passed, the error message "PST error" appears on LCD.
