12.5.2. Voltage Hysteresis (HYSVOLT)
The default settings were already chosen to be suitable for most applications. Changes are
only necessary in exceptions.
The hysteresis function was programmed to prevent undesired alarms. Hysteresis will cause
the alarm threshold to change after the hysteresis value is exceeded. This requires the
analogue value to enter the permitted area further before the alarm condition is reset.
These hysteresis values are set independently of the alarm value with the following commands:
SET HYSVOLT <Value> #1513
The parameter „Value“ represents the voltage:
0 … 99
1 = 0.1 V (Default setting: 0.1 V)
The value „0“ deactivates this function.
Reset to factory settings:
The following command resets the settings to factory settings:
RESET HYSVOLT #1513
Checking settings
The settings made may be reviewed with the following command:
TEST HYSVOLT #1513
