Meaning of error codes

11.3.4.1

1 Remaining control deviation

The deviation between the setpoint and the actual value is continuously monitored in
"Automatic" mode. The fault message for a remaining control deviation is activated depending
on the setting of the application parameters " TIM" - monitoring time for setting the fault
messages - and " LIM" - response threshold for the fault message. The fault message is
cancelled as soon as the control deviation drops below the response threshold. This monitoring
function is always active.
11.3.4.2

2 Device not in "Automatic" mode

When the device is not in automatic mode, an error message is generated if the ' FCT'
parameter (function of fault message output) is set correctly. A warning is then sent to the
control system if the device was switched to manual or configuration mode on-site.
11.3.4.3

3 Binary input BIN1 or BIN2 active

If the binary input is activated, an error message is generated when the " FCT" parameter
(function of fault message output) and the "BIN1" parameter (function of binary input 1) are
set correctly. For example, it can be a switch to monitor the packing glands, a temperature
switch or a limit switch (e.g. for pressure).
Binary input 2 (in the optional alarm module) can be configured in a similar manner.
11.3.4.4

4 Monitoring the number of total strokes

The diagnostics value "1 STRKS" is constantly compared with the thresholds that are
determined from the "L1.LIMIT" to "L4.FACT3" parameters. If the thresholds are exceeded,
the fault message output or the alarm outputs respond depending on the mode of the extended
diagnostics. These two functions can be deactivated using the parameter setting "OFF" for "L.
STRK".
