Controller setpoints can be entered double as a standard value and an alternative value. Setpoint toggle allows
changingbetweenthesetwovalues.Setpointtogglingcanbemadeintwoways:
External: By voltage applied to 230 V- Digital Input 2 (Terminal D21/D22, factory setting) by a switch or
timer. Alternatively, with an appropriate parameterization of the digital inputs (menu 6-2-4), the setpoint
switch can be carried out via digital input 1 (terminals D11/D12) or digital input 4 (terminals D41/D42). The
functionofthedigitalinputscanbeconfiguredviatheparametersInv.D1 to Inv.D4(menu6-2-4).Ifmore
than one input has been parameterized with the same function, then this function is active as soon as a
signal is applied to one of these inputs.
Internal:Bysettingtoggletimesontheinternalclock.(onlyactivewhentheparameterToggle interv.(Menu
3-3) is set to "--").
CAN bus: With the use of a system centre or a suitable store computer (version 4.24 or higher) he setpoint
can also be controlled from the system centre / store computer via CAN bus. Further information on setpoint
switching can be found in the system centre's / store computer's documentation in the chapter "Special
Inputs".
