How to Order

To order the TSB model use the diagram below.

TSB – R230 – 3/8

Standard Switch Trip Point

Specify trip point value. Example: TSB-R200

Standard Switch Trip Point
Values (rising)*			Accuracy
R165	= 165°F (74°C)
R180	= 180°F (82°C)		165– 210°F	±5°F (±2.7°C)
R200	=	200°F (93°C)	Water/glycol 10% used for
R205	=	205°F (96°C)	setpoint
R210	= 210°F (99°C)
R220	= 220°F (104°C)		215– 230°F	±7°F (±3.8°C)
R225	= 225°F (107°C)
			240– 250°F	±10°F (±6.5°C)
R230	= 230°F (110°C)
			Heat transfer fluid used for
R240	= 240°F (116°C)
			setpoint (276 viscosity @ 100°F)
R250	= 250°F (121°C)

*Non standard trip points require a minimum quantity order.

Trip point must be in 5°F increments between 165– 250°F (74–121°C).

Switch Reset Differential	±15°F (±8.3°C)
Switch Repeatability	±3°F (1.7°C)

** Standard connection.

† Includes copper seal.

2.Install the TSB switch in the engine water jacket location recommended by the engine manufacturer.

3.Install the appropriate adapter nut into the engine water jacket. Use thread sealant such as Teflon® tape as necessary.

4.Insert the sensing bulb through the adapter nut. The sensing bulb must be fully immersed in coolant/liquid flow so liquid flows across the sensing bulb.

5.Tighten the 5/8-18 UNF-2A compression nut to complete a liquid tight seal.

Wiring

CAUTION: DISCONNECT Electrical

Power before wiring.

1.See wiring schematic below. Switch contacts are shown with no temperature applied to the

TSB switch.

2. A spade (forked) terminal is recommended for all TSB switch connections.

3.Complete the wiring operation

making sure the voltage and current requirements are within the TSB switch electrical rating.

Teflon is a trademark of Dupont.
