To locate a controller, search on the part number such as 965A-1CD0-00RG. Use the Help feature in Adobe Reader on
how to search documents.
If there are multiple listings, then the retrofit is conditional upon field use. Select the appropriate selection. The User’s
Manual is included at the bottom of this document when availab le.
Before selecting a replacement controller:
1. Know the application.
• Temperature range
• Sensor type
• Is the sensor upgradable if required?
• Additional input requirements – remote set points, secondary sensor or events
• Output required – control, alarm, event
• Is the power-switching device upgradable?
• Operating voltage of controller
• Mounting requirements – panel space
• Is a safety limit device required?
2. Know the product.
• Inputs – type and number of
• Control function – direct (cool) or reverse (heat )
• Outputs – switched DC, SSR, or mechanical relay
• Communication requirements
• Which control features are required? (cascade, slidewire, differential, remote control, other)
3. Use your best judgment for selecting a replacement controller. All applications require close examination of input,
output and the control mode needs to have the controller function properly.
4. Safety: Remember to make sure all redundant safety equipment is in place and working when retrofitting equipment.
If a system has been retrofitted without the proper safety equipment, you could be liable if an accident occurs.
This is only a guide to replacement controllers. If you have doubts, please call (507) 454-5300
and ask for technical support or email wintechsupport@watlow.com. We’re here to help. The
suggested replacement will differ in fit and form. Please review the replacement controller
specifications for suitability. Carefully check the notes for additional information that may
apply.

Action – determines the direction of control. Heat (reverse acting) or Cool (direct acting).
Auto Reset – the limit will automatically reset on a power cycle but requires manual reset on limit trip.
Cascade – a control algorithm in which the output of one control loop provides a set point for another loop. The second
loop, in turn, determines the control action.
Ch – Channel refers to an analog input. There are single and dual channel controllers.
Control Mode – the method that a controller uses to switch the outputs such as PID, ON/OFF, and Manual.
Differential - control algorithm in which the output is based on the difference of the inputs plus set point.
DIN – Deutsche Industrial Norm, a set of technical, scientific and dimensional standards developed in Germany. RTD
sensors with the DIN curve change resistance at a rate of 0.00385 ohms/ohms/C.
DIN Rail – standard DIN EN50022 mounting method for attaching devices onto a metal rail.
Fixed – refers to a set point that is fixed at one value.
High Limit - device will deactivate output on a temperature rise above set point.
Inductive Load – any device that has a wire winding such as solenoids, electromechanical relays or transformers.
Input – refers to the sensor types that may be connected.
Integral – the set point in integral (on board) to the controller.
JIS – Joint Industrial Standards, a set of technical, scientific and dimensional standards developed in Japan. RTD sensors
with the JIS curve change resistance at a rate of 0.00396 ohms/ohms/C.
Line Voltage – the voltage required powering the electronics of the controller.
Low Limit - device will deactivate output on a temperature drop below set point.
On/Off – a method of control that turns the output full on until set point is reached and then off until the process error
exceeds the hysteresis.
Open Brd – the form factor of this controller is an open circuit board mounted on four standoffs.
Manual Reset – the limit must be reset on a power cycle and requires manual reset on limit trip.
Multi RSP – multiple remote set potentiometers were supported. Each allowed the set point to be selected and adjusted.
Relay – refers to an electromechanical relay.
Remote – set point is adjusted using a remote potentiometer.
Panel – the form factor of this controller is mounted through a hole cut in the panel.
PI – Proportional and Integral, a control mode with two functions: proportional action dampens the systems response,
and integral corrects for droop.
PID – Proportional, Integral, and Derivative, a control mode with three functions: proportional action dampens the
systems response, integral corrects for droop, and derivative prevents overshoot and undershoot.

The Watlow Series 142 is a compact, environmentally
protected safety limit temperature controller. The limit
has a single thermocouple input and is available in several
common ranges.
The 142 has a single mechanical relay output, and
operates as a high limit, latching control with manual
and/or auto-power reset. Fixed set points are available.
The Series 142 safety limit controller is ideally suited
for limit applications requiring tamper-proof operation,
agency approvals and immunity to hostile environments.
• The factory-fixed set point cannot be altered by operator
action or neglect.
• Agency approvals ensure compliance with recognized
standards.
• Epoxy potting makes the Series 142 resistant to envi-
ronments with vibration or humid/corrosive conditions.
Compact size and sub-panel mounting make the
Series 142 readily adaptable to many applications. Its
single, factory-fixed set point thermocouple input and
Form C, 3 amp electromechanical relay output provides
simplicity and reliability for many applications. Sensor
break protection ensures fail-safe process shut down upon
input failure.
We use note, caution and warning symbols throughout this manual 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. Be especially careful to read and follow all
cautions that apply to your application.
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 safety alert symbol, ç, (an exclamation point in
a triangle) precedes a general CAUTION or WARNING
statement.
The electrical hazard symbol, Ó, (a lightning bolt in a
triangle) precedes an electric shock hazard CAUTION or
WARNING safety statement.

Figure 2a — Series 142 dimensions.
Installation Procedure
1. Drill two 0.187 in. (5mm) diameter holes in the desired
panel location.
2. Mount the unit with two 6-32 screws, 0.25 in. (6mm) hex
nut and #6 internal tooth lock washer.
3. Use the correct thermocouple type per the model number on the unit sticker. See the side of the case.
• Use correct thermocouple polarity. Red is negative.
• Insulate the thermocouple mounting from the mount-
ing 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
contactors, motors, solenoids, etc.), use shielded thermocouple lead wire with the shield connected at the
sensor end only.
• Use a separate thermocouple to maintain the limit
function of this controller; do not parallel thermocouple input from the primary
controller.
4. All wiring and fusing must conform to the National
Electric Code (NEC) NFPA70 and any other locally
applicable codes.
5. Fuse the independent load voltage on the L1 (hot) side
and connect it to the common (C) side of the relay.
NOTE: For applications where the CE mark is required, all quick
connect and spade terminals must be pre-insulated to meet IEC
730 specifications.
Units With Remote Setpot Assembly
1. Drill two 2.0 in. (51mm) diameter holes in the desired
remote setpot assembly location. See Figure 2b.
2. Using the dial scale as a location template, center and
mark all four mounting holes on the dial scale with a
center punch.
3. For bolted dial scale assembly, drill four 0.125 in. (3mm)
diameter clearance holes. If you are using a screw
assembly, use a tap drill. Tap drill sizes used are:
Tap Drill Size Screw/Thread Size
#44 - 0.086 in. dia. (2mm) #4.36
#43 - 0.089 in. dia. (2mm) #4.40
#42 - 0.093 in. dia. (2mm) #4.48
4. Drill four 0.189 in. (5mm) diameter holes in desired
panel location. See Figure 2b.
5. Mount the Series 142 with four screws.
6. Connect sensor, load and remote setpot assembly per
Wiring Diagram. See the wiring pages.
Figure 2b — Setpot dimensions and mechanical zero
location.
Dial Scale Alignment to Mechanical Zero
1. Turn the dial scale knob completely counterclockwise (to
mechanical zero).
2. If the “Indicator” line on the setpot knob skirt, and
“Mechanical Zero” (represented by a small line beyond
the low end of the scale) are not aligned, loosen both set
screws on the setpot knob, and rotate the knob until
both lines meet.
3. Tighten both set screws.

Watlow Series 142 User’s Manual ■ 7
automatic power reset — A feature in latching limit
controllers that does not recognize power outage as a limit
condition. When power is restored, the output is re-energized automatically, as long as the temperature is within
limits.
electrical noise immunity — Ability of a temperature
control to operate normally in the presence of electrical
noise interference.
fixed set point — Temperature set point is preset at the
factory. It cannot be readjusted in the field.
latched output — Limit control output latches in deenergized condition when overtemperature condition
occurs and cannot be reset unless temperature drops
below set point.
limit or limit controller — A highly reliable, discrete
safety device (redundant to the primary controller) that
monitors and limits the temperature of the process or a
point in the process. When temperature exceeds or falls
below the limit set point, the limit controller interrupts
power through the load circuit. A limit controller can protect equipment and people when it is correctly installed
with its own power supply, power lines, switch and sensor.
manual reset — A feature on a limit controller that
requires human intervention to return the limit to normal
operation after a limit condition has occurred.
safety limit — An automatic limit intended for use in
applications where an over-temperature fault may cause a
fire.
