WATLOW Series 982 User’s Manual 1.1
Starting Out with the Watlow Series 982, Chapter 1
Watlow’s Series 982, a 1/8 DIN microprocessor-based ramping controller, is
truly an innovation in the controller field. The Series 982 provides 6-step program capability, with up to 4 files possible.
The new controller meets a wide variety of needs in the process industries.
Its broad range of I/O options allows control of virtually any process variable. In addition to the standard Watlow features, the Series 982 has
expanded auto-tuning capabilities and increased alarm functionality.
If you are unfamiliar with general controller operation, it’s a good idea to
read through the entire manual. The manual is organized in chronological
order with each chapter broken down by wiring, menus, operation and
applications. If you understand the concept of process/temperature controllers and feel comfortable skipping around through the manual, use the
index or the black tabs at the top of each page to quickly scan the pages
and find the topic you are looking for.
The map on the next page provides an overview of all menus and prompts
and how to navigate between them. There are three main prompts Setup,
Operation and Factory (
[`SEt], [OPEr] and [Fcty]). Beneath these
prompts there are several menus. The Display Loop can be reached from
anywhere using the Display key.

Installing the Series 982
Installing and mounting requires access to the back of the panel.
1. Make a panel cutout.
2. To remove the controller chassis from its case, press in firmly on the two
tabs on one side or the top of the bezel until they unsnap, then unsnap
the two tabs on the opposite side or the bottom. Pull the chassis out of
the case by gently rocking it.
3. Slide the case into the panel cutout. Check to see that the gasket is not
twisted, and is seated within the case bezel flush with the panel. Slide
the mounting collar over the back of the control.

4. Loosen the mounting bracket screws enough to allow for the mounting
collar and panel thickness. Place each mounting bracket into the
mounting slots (head of the screw facing the back of the controller).
Push each bracket backward then down to secure it to the control
case. To guarantee a proper NEMA 4X seal, Series 982 and 984
units (vertical) must have the mounting brackets located on either
side of the unit. When installing Series 981 and 983 units (horizontal) the brackets must be on the top and bottom of the unit.
5. Make sure the case is seated properly. Tighten the installation screws
firmly against the mounting collar to secure the unit. To ensure a
NEMA 4X seal, there should be no space between the bezel and
panel. Overtightening the screws will distort the case and make it diffi-
cult to remove or replace the controller.
6. Insert the controller chassis into its case and press the bezel until all
four tabs snap. Make sure the inside gasket is seated properly and not
twisted.
7. To release the mounting brackets, loosen the mounting bracket screws
and push the brackets forward, then pull it up and out.
ç
CAUTION:
Follow the installation procedure
exactly to guarantee
a proper NEMA 4X
seal. Make sure the
gasket between the
panel and the rim of
the case is not
twisted and is seated properly. Failure
to do so could
result in damage to
equipment.

2.4 WATLOW Series 982 User’s Manual
Installation and Wiring, Chapter 2
Wiring
Wiring the Series 982
Wiring options depend on the model number and DIP switch settings.
Check the terminal designation stickers on either side of the controller
and compare your model number to those shown here and with the model
number breakdown on the inside back cover of this manual.
Input-to-output Isolation
The Series 982 uses optical isolation between the analog inputs and the
controller outputs/digital input. This isolation provides a 500VÅ (VAC)
barrier to prevent ground loops when using grounded sensors and/or
peripheral equipment.
Here is a breakdown of the isolation barriers:
• Analog inputs 1 and 2 are grouped together.
• Outputs 1 through 4 and the standard event input are grouped together.
This does not apply to Output 4 when configured as communications.
• The digital communications output (4) is separate from the above
groups.

Sensor Installation Guidelines
Thermocouple input: Extension wire for thermocouples must be of the
same alloy as the thermocouple itself to limit errors.
100 Ω RTD input: Each 1Ω of lead wire resistance can cause a +2°F
error when using a two-wire RTD. A three-wire RTD sensor overcomes this
problem. All three wires must have the same electrical resistance (i.e.,
same gauge, same length, multi-stranded or solid, same metal).
Maintain isolation between input 1 and input 2 to prevent a ground loop.
A ground loop may cause incorrect readings, dashes across the upper display or the display of error codes.

WATLOW Series 982 User’s Manual 2.5
Installation and Wiring, Chapter 2
Wiring
Wiring 0-20 and 4-20mA Process Inputs
Certain “transmitters” used in process input applications are producing
internal resistor failures in the Watlow Series 988 family of controllers.
This is only apparent with the Series 988 family 1/8 DIN units with
Process Inputs selected (0-20mA or 4-20mA dc only).
We are noticing that an external resistor is required to prevent a high
in-rush current which burns out the Series 988 family controllers’ 7-ohm
internal resistor. This high in-rush current occurs initially on “power-up.”
If the transmitter turns full on for a split second during power-up, the
available current weakens or damages the internal resistor.
Example: 20V / 7 ohms = 2,857mA (too much!).
The wiring diagram example below shows an application where a customer
is using a 4-20mA dc transmitter and power supply to feed the input of a
Series 988 controller. The Rx range (100 to 400 ohms) for the external
resistor is recommended. We suggest starting with 250 ohms.
Example: Customer is using a 24VÎ (dc) power supply to power up the
4-20mA dc transmitter that inputs to the Series 988 terminals 8 (-) and 10
(+). To figure out what the internal Series 988’s handling current is for the
0-20mA or 4-20mA dc input to the Series 988 controllers, we need to
apply Ohm’s Law: The square root of Watts divided by Resistance equals
Current. Applying that formula to the example below produces the following: Square Root of (0.125 Watts / 7 ohms) = 134 mA dc (handling input
current). This is the acceptable input current for the Series 988 universal
input board.
Reminder, the input impedance of 7 ohms handles the majority of our
customer applications; the external resistor (Rx) is only for certain transducers/transmitters that spike on power-up or power-down. Please make
sure your customer’s transmitter / transducer fall within our Series 988
family (1/8 DIN) of controllers’ Process Input specification of 7 ohms input
impedance.

Input Prompts
When you are in the Setup menus, the Series 982 displays the menu selection ( [InPt], [OtPt], [GLbL] or [COM] ) in the upper display, and [`SEt] in
the lower display.
The Up-arrow > or Down-arrow key < selects another menu. Press the
Mode key µ to display the prompt in the lower display and its value in the
upper display. Use the Up-arrow > or Down-arrow < key to change the
value in the upper display. The new value will not take effect until after a
five-second delay or until you press the Mode key µ.
Input 1
Select sensor type for input 1. This selection must match the sensor type
connected to terminals 8, 9 and 10. See Appendix for more information
about sensors.
• Changing the value of [`In1] changes all other prompts to the factory
default values, except the Communications and Lockout menus, the
[`C_F] prompt in the Global Menu and the [`dFL] prompt in the
Calibration Menu. If you change the value, the default warning [dFLt]
will flash in the upper display.
• Changes do not take effect automatically after five seconds; you must
press the Mode key µ to enter the sensor type change and advance to
the next prompt.
[`In1] This prompt always appears.
