3.12.4 ALARM – Alarm
When an alarm / message is generated in the positioner, it is signaled via the digital and analog outputs. You can use the ALARM
parameter to select a higher or lower alarm current for analog feedback
NOTE
Without electrical power or during initialization the output signal is> 20.5 mA. A special version (hardware
change) is also available, with which a value of< 3.8 mA is also possible.
HIGH_CUR Alarm current I > 20.5 mA
LOW_CUR Alarm current I < 3.8 mA
3.12.5 RB_CHAR – Count back characteristic curve
You can use this parameter to determine whether the position indicator and the analog position feedback follow the characteristic curve
set in parameter CHARACT - Characteristic curve.
3.12.6 TEST – Test
Test is for simulation of the analog output. The test allows you to simulate effects during commissioning without affecting the normal
process.
NOTE
The test is automatically stopped after two minutes. While the test is running, the corresponding message (see
below) flashes in the display.
NONE No function
FAILED
Simulation of position feedback failure (CPU). I > 20.5 mA (standard) or I < 3.8 mA (special
version, changed hardware)
ALRM_CUR Simulation of an alarm current < 3.8 mA or I > 20.5 mA
CURRENT
Output of the current setpoint as current value via analog output. All configurations and
settings of the analog input and /or output must be taken into consideration.
