  • Page 61 Liquicap M FTI51, FTI52 Commissioning 6.4.2 Performing calibration Note! • An empty and full calibration provides the greatest possible operational security. This is particularly recommended for critical applications. • The empty and full calibration measures the capacitance values of the probes when the tank is full and when it is empty.
  • Page 62 Commissioning Liquicap M FTI51, FTI52 6.4.3 Setting the switch point adjustment Note the following when selecting switch point adjustment: • If only one calibration (empty or full) was carried out, and if buildup forms on the rod probe while the probe is in operation, the device may no longer respond to changes in level. A switch point adjustment compensates for this condition and ensures that you obtain a constant switch point again.
  • Page 63 Liquicap M FTI51, FTI52 Commissioning 6.4.5 MIN/MAX failsafe mode Note! By selecting the failsafe mode correctly, you ensure that the output always operates safely with quiescent current. • Minimum failsafe mode (MIN): The output switches if the switch point is undershot (rod/ rope uncovered), a fault occurs or the line voltage fails.
  • Page 64 Pressing test key C disconnects the supply voltage. If the power supply is disconnected, a supply unit such as Nivotester FTL325N from Endress+Hauser reacts in such a way that the alarm relay outputs an error and appropriate responses are triggered in any slave devices connected.
