Issue:
Logic and Control Voltage specifications for ATS22... S6/S6U Soft Starters.

Product Line:
Altistart ATS22

Environment:
S6
S6U

Cause:
Control voltage and logic input max voltages allowed.

Resolution:
The S6 version was primarily designed for the European market and has  control voltage range (for terminals CL1 and CL2) of 187V AC to 264.5V AC (220 -15% to 230 +15%)).
The softstart then generates a 24VDC power supply (24VDC +/- 6 V) that is limited to 42 mA.  This supply can be measured between terminals +24 and COM on the control terminal strip and should be present when the 220V power is supplied to the softstart.

The S6U was designed and qualified for the standard NEMA range, which is: 103.5 ... 126.5V AC and is primarily used in the US.
The allowed voltage on ATS22•••S6U control terminals (input CL1 and CL2) is from the range: 93.5V ... 126.5V, 50/60 Hz (110 -15% to 115 +10%)
