Overview

Introduction

Watlow’s Series 97 is a microprocessor-based controller with a single input, second auxiliary input and four outputs. Input 1 is used to measure temperature from a thermocouple or RTD sensor. Input 2 can be utilized as a remote reset switch or a hardware lockout switch. With up to four outputs, the controller is versatile in handling applications that require a high/low limit, alarms, retransmit and communications. The controller is so user friendly it can be set up to display safety and limit messages created by the end user to meet the exact application need.

The Series 97 limit controller is added to thermal applications to limit over-temperature conditions. The Series 97 controller provides safety assurance against instances where a high temperature runaway condition could occur from a shorted input sensor or an output device that could fail in a closed position.

The Series 97 is recommended for any application where thermal runaway could result in large product scrap costs, affect operator safety, cause damage to equipment, or create a fire hazard.

The Series 97 is manufactured by ISO 9001-registered Watlow Winona and reliably backed by a three-year warranty.

Installing the Series 97 Controller

Installing and mounting requires access to the back of the panel.

1. Make the panel cutout using the tear-out mounting template found on the previous page, or the dimensions found in this chapter.

2. Check to see that the gasket is properly seated into the gasket channel on the front bezel and that it is not twisted. Make sure that the rounded surface of the gasket is the surface that is exposed from the gasket channel, as this is the surface that will mate to the panel surface. Insert the controller into the panel cutout.

3. With the controller inserted into the panel cutout, take the retention collar and slide it over the controller, making certain that the two locating holes in the retention collar are visible from the rear of the controller, with one hole pointing up and one pointing down. Then, take the mounting collar and slide it over the controller, making certain that one cantilever is pointing up and one is pointing down also. With one hand holding the controller and the other hand using a #2 Phillips screw driver, tighten the two screws in the mounting collar until the gap between the bezel and panel surface is .025” maximum. See figure below. Make sure that you cannot move the controller back and forth in the cutout. If you can, you do not have a proper seal.

Figure 2.2a - Installing the controller. Figure 2.2b - Series 97 gap dimensions.

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.

NOTE: Be careful not to over-tighten the screws. This may cause the mounting cover to fail. Over-tightening occurs when the front bezel is touching the customer’s front panel.

Removing the Series 97 Controller

1 Hold the controller with one hand while using the other hand to loosen the screws with

a #2 Phillips screwdriver until the end of the screw is flush or past the end of the cantilevers, see the figure below.

2. After the screws have been loosened, hold the controller with one hand while squeezing the two screws together with the other hand. Then simply slide the mounting collar off the controller.

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 97

Wiring options depend on the model number. 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.

NOTE: Using the Diagnostics Menu (Factory Page) check Output 1 Hardware through Output 4 Hardware, [Oty1] through [Oty4]. See Chapter Six for information about the menu and range of settings for each output. These outputs may differ from those listed for the model number on the controller and described in this manual, indicating a customized hardware setup.

Input-to-output Isolation

The Series 97 uses optical and transformer isolation between the analog inputs and the controller outputs, including the communications interface. This isolation provides a 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 are grouped together. This does not apply to Output 4 when it is configured for communications.

• If Output 4 is configured for communications, it is isolated from the the other inputs and outputs.

Figure 3.2 — Isolation blocks.

There are no electrical connections between these blocks.

Figure 3.3 - Power wiring.

Sensor Installation Guidelines

Thermocouple inputs: Extension wire for thermocouples must be of the same alloy as the thermocouple to limit errors.

When using a voltage input for the digital event on Input 2, use an ungrounded thermocouple on Input 1. If a grounded thermocouple is required, the signal to input 2 must be isolated to prevent possible ground loops.

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, multistranded or solid, same metal).

ç

CAUTION: If high voltage is applied

to a low-voltage unit, irreversible damage will occur.

ç∫

WARNING: To avoid damage to

property and equipment, and/or injury of loss of life, use National Electric Code (NEC) standard wiring practices to install and operate the Series

97. Failure to do so could result in such damage, and/or injury or death.

ç

CAUTION: 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. Failure to follow this guideline could result in damage to equipment.

Watlow Series 97 Wiring ■ 3.11

NOTE: Successful installation

requires five steps:

• Choose the controller’s hardware configuration and model number (Appendix);

• Choose a sensor (Chapters 3 and 6, and Appendix);

• Install the controller (Chapter 2);

• Wire the controller (Chapter 3) and

• Configure the controller (Chapters 4, 5 and 6).

NOTE: The CMC converter

requires an external power supply when used with a laptop computer.

ç

WARNING: To avoid damage to

property and equipment, and/or injury of loss of life, use National Electric Code (NEC) standard wiring practices to install and operate the Series 97. Failure to do so could result in such damage, and/or injury or death.

NOTE: If the system does not

work properly, it may need termination resistors at each end of the network. A typical installation would require a 120-ohm resistor across the transmit/receive terminals (19 and 21) of the last controller in the network and the converter box or serial card. Pull-up and pull-down resistors may be needed to maintain the correct voltage during the idle state.
