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.

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.

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.

Range Low 1 and Range High 1

Select the low and high limits for input 1. These prompts limit the adjustment range for the set points. The default values are the same as the limits of the sensor you selected by setting the input 1 DIP switch and selecting a value for Input 1 [`In1].
• Process inputs are scaled by these values. Range high is the value dis­played when the maximum process signal is present at the input. Range low is the value displayed when the minimum process signal is present at the input.
Example: Set [`In1] to [4-20]mA.
Set [`rL1] to [`100]. Set [`rH1] to [`500]. A 4mA input will display [`100]. A 12mA input will display [`300]. A 20mA input will display [`500].
• The low and high values of each sensor type are listed on the specifica­tions page of the Appendix.
