Figure 1.1 -
Watlow Ramping
Controllers.
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.

DIP Switches
DIP Switch Locations and Functions
The Series 982 has several Dual In-line Package (DIP) Switches inside the control. Depending on your model number, your unit can have as few as one DIP switch or as many as five DIP switches. Use the rest of this chapter as a DIP switch reference guide.
To set any DIP switch:
1.Remove the control chassis from the case. Release the two tabs on one side of the bezel, by pressing in firmly on each until you hear the tab snap. Release the two tabs on the opposite side of the control. You may need to rock the bezel back and forth several times to release the chassis.
2.Use the following graphics in the rest of the chapter to locate and identify each DIP switch and the desired settings.

NOTE:
Removing the controller chassis from its case makes mounting easier.
Figure 2.2 -
Side and top view.
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.

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.
Installation
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 difficult 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.

WARNING:
To avoid potential electric shock, use National Electric Code (NEC) 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 or death.
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
NOTE: Input-to-output isolation is defeated when the external signal conditioner power supply option is used to power a transmitter connected to input 1.

CAUTION:
If high voltage is applied to the low voltage unit, irreversible damage will occur.
Sensor Installation Guidelines
Thermocouple input: Extension wire for thermocouples must be of the same alloy as the thermocouple itself to limit errors.
1 0 0 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.

Figure 2.5 - Process wiring example.
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.

Press the Display key ∂ to return to the Display Loop from any point in any menu.
Navigating the Setup Menus
To reach the Setup Menus, begin in the Display Loop and press both the Uparrow > and Down-arrow < keys for three seconds. The Setup Menu prompt [`SEt] will appear in the lower display, and the Input Menu prompt [InPt]] will appear in the upper display. The four Setup Menus are: Input [InPt]; Output [OtPt]; Global [GLbL]; and Communications [COM]. Use the Up-arrow > or Down-arrow < key to select a menu and the Mode key µ to step through a menu. The Communications Menu appears only on units equipped with the data communications option.
You will not see every prompt in any of these menus. The unit’s configuration and model number determine which prompts appear. After stepping through each menu, the Series 982 returns to the Setup Menu prompt [`SEt]. Use the Up-arrow > and Down-arrow < keys to select the next menu, or use the Mode key µ to advance through the same menu again. To move backwards through the menu hold the Mode key µ down and press the Uparrow key >. Use the Up-arrow > or Down-arrow < key to change the prompt setting.
Refer to the Appendix for model number options. For information about communications and the communications prompts, refer to the supplemental manual Data Communications with the Watlow Series 988 Family of Controllers.
