OT: Can two of the Telemecanique XS4P30MA230 proximity switches (door interlocks on a drum mixer) be wired in series to control the Enable function on a TB Woods 50 HP, 480 volt variable frequency motor drive?
The drive has a 24 VDC control circuit. To enable it, you connect +24 vdc from the drive to a switch contact, then back to the EN terminal. I know that ONE proximity switch will work, but will two in series? Will the first switch close and send voltage to the second, allowing it to function if it sees a target? Will the additional current exceed the 200mA (DC) limit of the second switch? Will the added resistance be two much for the drive transistor detector circuit?
