Output Filter Time Interval
To smooth the current output, a low-pass filter with adjustable time interval can be switched on.
When there is a jump at the input (100%), the output level is at 63% after the time interval has been
reached. The time interval can be set from 0 to 120 sec. If the time interval is set to 0 sec, the current
output follows the input.
Note: The filter only acts on the current output, not on the display, the limit values or the controller!
Current During Function Check (HOLD)
Depending on the parameter setting, the current outputs switch to one of the following states:
• Current measurement
• Last measured value (factory setting)
• Fixed value
Message when the Current Range is Exceeded
As delivered, the “Failure” message is generated when the current range is exceeded
(< 3.8mA or > 20.5mA). This setting can be changed in the parameter settings for the respective
measuring channel in the
Messages menu:

Use of Relay Contacts
The following uses are possible:
• Off
• Failure
• Maintenance required
• Out of specification
• Function check
• Limit value
• Rinse contact
• Rinse contact (channel) (if using two channels)
• Parameter set B active
• USP output (with conductivity sensor only)
• Sensoface
• Sensoface (channel) (if using two channels)
The switching behavior can be adjusted (normally open or normally closed contact).
• N/O/normally open/make contact: the relay contact closes when it is activated.
• N/C/normally closed/break contact: the relay opens when it is activated.
ON/OFF delays can also be configured.
Settings can be changed in the Relay Contacts submenu:
