The GRACO 563273 is a moisture-resistant cycle switch (SPDT) and bracket assembly designed to monitor piston movement in lubrication systems. It is constructed for durability and is intended for use with MJ, MS, MHH, and MXP divider valves to ensure completed lubrication cycles. The assembly provides positive feedback based on actual metering piston movement and is suitable for integration with controllers, starters, or PLCs.

Key Features:

• Cycle Switch (SPDT) and Bracket Assembly
• Moisture-resistant materials
• MJ, MS, MHH, and MXP divider valves
• Monitors piston movement to ensure completed lubrication cycle
• Must have cycle indicator pin
• Provides positive feedback based on actual metering piston movement
• Mounts to MJ, MSP, MXP, or MX divider with cycle pin option
• Simple installation
• Able to be set for normally open or normally closed operation
• Six steel balls in a clear sleeve follow a magnet which moves with the cycling piston, providing a clear visual indication of lube cycles

Applications:
Used in lubrication systems to monitor and confirm the completion of lubrication cycles, ensuring reliable operation of MJ, MS, MHH, and MXP divider valves in industrial environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Mounts to MJ, MSP, MXP, or MX divider with cycle pin option for simple installation
• Ensure the cycle indicator pin is present for proper function
• Integrates with controllers, starters, or PLCs for automated feedback
• Set switch for normally open or normally closed operation as required by the system
• Regularly inspect the clear sleeve and steel balls for smooth movement and visual indication
• Check for moisture resistance integrity to prevent corrosion or malfunction
• Consult the equipment manual for specific maintenance intervals and procedures
