NOTICE
• Operating mode selection switches without test pulses enable 2 to 8 operating modes;
operating mode selection switches with test pulses enable 2 to 4 operating modes.
• When wiring the tested operating mode selection switches, note that when using an odd-
numbered test output (e.g. T1, T3 ... or X1, X3 ...), odd-numbered inputs (e.g. I1, I3, I5 ...)
must be used; when using an even-numbered test output (e.g. T2, T4 ... or X2, X4 ...),
even-numbered inputs (e.g. I2, I4, I6 ...) must also be used.
• You can find additional information in the operating instructions for the operating mode
selection switches.
