4.5 Wiring test
When the peripheral equipment is connected, you can perform a wiring test in the
TEST (wiring test) menu. We recommend testing after configuration and settings
are complete. The test provides the following functions:
Functions
• Display of reading values for inputs
• Switching of aggregates connected to the outputs, such as pumps
• Preselection of a 0…100% signal for step switches, where the relays are
switched
The application is deactivated during the wiring test. The outputs are in a defined
OFF state, and safety-related functions (e.g. frost protection) are deactivated!
The wiring test provides checks for the following errors at the inputs and outputs:
Error checks
• Connection error (mixed up wires)
• Position error (mixed up sensors or actuating devices)
• Discrepancies between connection method and controller configuration (LG-
Ni1000 in place of active DC 0…10 V)
