The W0168 and W0241 panel kits are universal-fit instrument panels for most industrial engines. They include SWICHGAGE® protection for low engine oil pressure and high coolant or high oil temperature. These Panel Kits are similar–the W0168 has a start/stop key switch and the W0241 has a start push button.

Panel kits include:

• Low Lube Oil Pressure SWICHGAGE®
• High Coolant/Oil Temperature SWICHGAGE®
• 518PH Magnetic Switch
• Emergency stop push button
• Ignition key switch for start/stop (W0168)
• Push button for start (W0241)
• Ammeter 60-0-60
• Provisions for additional SWICHGAGE® controls, such as irrigation pump pressure or engine oil temperature
• Provisions for tachometer and throttle cable

SWICHGAGE® is two-instruments-in-one: (1) an accurate indicating gage with (2) a built-in, adjustable limit switch.

A 518PH Magnetic Switch provides a CLOSED-LOOP circuit to ensure proper operation at all times. The 518PH allows the system to be sensitive to open circuits, broken wires, false grounds, corrosion, loss of power and other factors which could otherwise prevent the protective controls from operating. It can be wired to either make or break a circuit for shutdown.

The universal mounting panel is enclosed on all 4 sides with open back. An optional back cover (model no. 30050800) is available for both kits. Panel Kits are prewired and ready to install and are available for 12 or 24 VDC systems.*
