Watlow’s Series 147 is an open-board temperature limit

with a thermocouple or RTD sensor input.

The Series 147 is designed to meet the needs of a wide range of temperature limit applications. Installation and setup are simple and easy, using basic hand tools. Factory selectable options include high or low limit with either manual or automatic reset on power loss.

The Series 147 has an LED output status indication and can be ordered with an integral or a fixed set point.

Use the following procedure to mount and install the

Watlow Series 147 temperature limit control.

1. Locate and drill four 0.156 in (4 mm) holes in the desired panel location. See Figure 2 for hole locations.

2. Mount the Series 147 using four #6 screws.

3. Connect the sensor, load, and power as illustrated in the wiring diagrams on pages 2 and 3.

Figure 4a — Series 147 dimensions.

• Use the correct sensor type per the model number on the unit sticker.

• Use the proper thermocouple or RTD polarity.

• Insulate the thermocouple mounting from the mounting surface to prevent heat migration input errors.

• Thermocouple leads should be twisted pair wire and routed separately from any other lines.

• In electrically noisy environments (heavy switching of contactor, motors, solenoids, etc.) use shielded thermocouple lead wire with the shield connected at the sensor end only.

• All wiring and fusing must conform to the National Electric Code (NEC) NFPA70 and any other locally applicable codes.

• Fuse the independent load voltage on the L1 (hot) side and connect it to the common (COM) side of the relay.

• Long lead lengths create electrical resistance. When using a two-wire RTD, there will be an additional input error

for every 1Ω of lead length resistance. That resistance

when added to the resistance of the RTD element, can result in erroneous input to the temperature limit. To overcome this problem, use a three- wire RTD sensor, which compensates for lead length resistance. When extension wire is used for a three-wire RTD, all three extension wires must have the same electrical resistance (i.e. same gauge, copper stranded).

Note, caution and warning symbols appear throughout this book to draw your attention to important operational and safety information.

A “NOTE” marks a short message to alert you to an important detail.

A “CAUTION” safety alert appears with information that is important for protecting your equipment and performance.

A “WARNING” safety alert appears with information that is important for protecting you, others and equipment from damage. Pay very close attention to all warnings that apply to your application.

The ç symbol (an exclamation point in a triangle) precedes a general CAUTION or WARNING statement.

The Ó symbol (a lightning bolt in a lightning bolt in a triangle) precedes an electric shock hazard CAUTION or WARNING safety statement.

Figure 4b — Power wiring.

WARNING: To avoid potential electric shock, use National Electrical Code safety practices when wiring and connecting this unit to a power source and to electrical sensors or peripheral devices. Failure to do so could result in injury and death.

All wiring and fusing must conform to the National Electric Code and to any locally applicable codes. Failure to comply with these recommendations could result in damage to equipment and property, and injury to personnel.

CAUTION: The Series 147 temperature limit should be mounted in an inconspicuous location to discourage unauthorized changes to the set point. Only approved and appropriate personnel should have the authority to change the set point on the limit switch. Failure to comply with these recommendations could result in damage to equipment and property, and injury to personnel.

CAUTION: Applying incorrect voltage may result in irreversible damage to the controller.
