TB124 Rev1 Yuasa Rotary Table Clamp Voltages 24VDC vs 110VAC
Purpose
How to tell the difference between 24VDC and 110VAC clamp voltage on Yuasa rotary tables
Description
Yuasa rotary tables can be purchased with a 24VDC or a 100VAC clamping solenoid Prior to October 2000
Centroid supplied 24VDC systems This required that a power supply be mounted in the main cabinet to
supply this voltage After October 2000 rotary tables are being ordered in as 100VAC and main cabinets are
being wired for 100VAC 24VDC clamping can still be ordered as an option if needed
Determine solenoid voltage
Telling whether a table has a 24VDC or 100VAC solenoid requires you to check at least one or all of the
following
1 Check the rotary table manual for solenoid voltage
2 Inspect solenoid visually for markings See pictures next page
3 Connect 24VDC to pins A and B on the connector If the solenoid and brake are activated the solenoid is
24VDC if not it is 100VAC
Note If 100VAC is connected to a 24VDC table there is a risk of permanent damage to the solenoid
The Yuasa clamp operation is dependent on the voltage applied to the connector at pin B and through a PLC
output to pin A Check the unit schematic for the correct PLC output
For 24VDC operation connect 24VDC+ to the correct PLC output common and 24VDC common to pin B
For 110VAC operation connect 110VACH to the correct PLC output common and 110vacn to pin B
