Conrad 393903 time 393903 Data Sheet

• This PC software may be used to configure different switching functions as well as logical operations of the inputs.

• In the delivery condition, the operating mode „Power surge switch“ is preset.

• Data transfer to the multifunction timer is performed via the Voltcraft USB programming cable (Conrad item no. 197339).

• The data interface serves only parameter transmission. It must not be connected to a computer during operation.

The PC software is available free of charge at www.conrad.com in the download area for the „MFT1816“ (supported operating systems: Windows
XP and higher)

The Voltcraft USB-programming cable (Conrad item no. 197339) is needed for data transfer. It must be connected to the J3-connection
of the multifunction timer.

Configuration by PC-software is performed in the potentiometer range of 98…100% (display by flashing LED „STAT“).

Switching of an input is explained in these operating instructions using the illustrated buttons. A pushed button is defined as a positive
level. Since these are optocoupler inputs, only one current flow is decisive for switching. The polarity is irrelevant for this.
