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 and the right valve
piping by directly applying current to the IP module with the UP and DOWN
keys (no control; software limit values such as “stroke 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
defective.
After leaving this menu (by pressing the M key or UP+DOWN) the actual
setpoint is automatically restarted.
