Programming NB 3000 Nivobob
Relay 3
Selects, if relay 3 shall indicate Failure, Maintenance or both situations.
Relay 4
Selects, if relay 4 shall indicate "Upper stop position" or Maintenance.
Timer
Automatic start of measurement with timer function.
The timing interval between two measurements can be adjusted between 0.05h (3 minutes) for the version
with brushless motor (otherwise 0,1h (6 minutes)) and 99.9 hours. Position „off“ causes no automatic
measurement start.
The timer will be reset:
• after finishing a measurement
• after linking the terminals 24/26 (measurement interruption during filling)
For automatic measurement at a predetermined time of day, an external start unit connected to terminals
24/25/27 is necessary.
To avoid needless wear and tear, the unit should not be started more often than necessary.
