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.

Watlow Series 97 Installation ■ 2.1

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.

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.

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).

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.

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 Features ■ 5.1

Limit

The Series 97 limit controller is added to thermal applications to limit over- or under-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. A limit condition is latched and therefore requires operator intervention to clear it. This is done by pressing the Reset key after the limit condition has passed.

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.

5.2 ■ Features Watlow Series 97

Watlow Series 97 Features ■ 5.3

Input

Calibration Offset

Calibration offset allows a device to compensate for an inaccurate sensor, lead resistance or other factors that affect the input value. A positive offset increases the input value, and a negative offset decreases the input value.

The input 1 offset value can be viewed or changed with Calibration Offset 1 [CAL1] (Limit Menu).

Figure 5.3 — Calibration offset.

Actual Process Temperature

Negative Calibration Offset will compensate for the difference between the Sensor Reading and the Actual Temperature.

Time

Filter Time Constant

A time filter smooths an input signal by applying a first-order filter time constant to the signal. Either the displayed value or both the displayed and control values can be filtered. Filtering the displayed value makes it easier to monitor.

View or change the input 1 time filter with Filter Time Constant 1 [Ftr1] (Input 1 Menu). A positive value affects only the viewed values. A negative value affects both the viewed and control values.

Sensor Selection

You need to configure a controller to match the input device, which is normally a thermocouple or RTD. When you select an input device the controller automatically sets the input linearization to match the sensor. It also sets high and low limits, which in turn limit the range high and range low values.

Use Sensor Type 1 [SEn1] and Input 1 [In1`] (Input 1 Menu) to select the appropriate sensor for input 1.

Range Low and Range High

The controller constrains the set point to a value between range high and range low. Range high cannot be set higher than the sensor high limit or lower than range low. Range low cannot be set lower than the sensor low limit or higher than range high.

Use Range Low 1 [rL1`] and Range High 1 [rh1`] (Input 1 Menu) to select or view values for the corresponding input 1 parameters.

Event Input

With an event input an operator can perform certain operations on a system by opening or closing a switch or applying a dc logic signal to the controller. This feature can add convenience, safety or security to a system.

Use Event Input Status [E`St] (Monitor Menu) to read the state of the event input parameter.

Watlow Series 97 Features ■ 5.7

Retransmit

The retransmit output can be used to transmit an analog signal representing the value of the input process variable. The retransmit signal can be configured as either a milliamp or a voltage signal. In choosing the type of retransmit signal the operator must take into account the input impedance of the external device and the required signal type, either voltage or milliamps.

A typical application might use the retransmit option to record a process value with a chart recorder.

Figure 5.7 — Retransmit example.

In the example a Series 96 is being used to control the temperature of a heat-treat oven and the Series 97 is being used as a safety limit with a retransmit output. Output 4 of the Series 97 must be equipped for retransmit (97_ _ - _ _ _ M - _ _ _ _).

The temperature of the limit process value is being recorded on a chart recorder. The oven temperature range stays between 600 to 900°F. The chart recorder requires a 4-20mA signal.

Set [Aout] Analog Output 4 (Output 4 Menu) to [Proc] Process 1 and [Prc4] Process 4 (Output 4 Menu) to [4-20] to tag the input 1 process value as the parameter to be retransmitted. Set Analog Output High [A`hi] to 900 to set the high range for the retransmit signal. Set Analog Output Low [A`Lo] to 600 to set the low range for the retransmit signal. Set Analog Output Offset [ACAL] to 0, assuming no calibration offset is required.

The retransmit output will be 4mA until the oven temperature is greater than 600°F, at which point the signal will increase with temperature to 20mA at 900°F and will not exceed 20mA.

Alarms

An alarm takes some action, usually notifying an operator, when the process temperature leaves a defined range. A user can configure how and when an alarm is triggered and whether it turns off automatically when the alarm condition is over.

Alarm Set Points

The alarm high set point defines the temperature that will trigger a high side alarm. The alarm high set point must be higher than the alarm low set point and lower than the high limit of the sensor range.

The alarm low set point defines the temperature that will trigger a low side alarm. The alarm low set point must be lower than the alarm high set point and higher than the low limit of the sensor range.

Process alarm set points for output 2 can be viewed or changed with Alarm 2 High [A2hi] and Alarm 2 Low [A2Lo] (Alarm Menu).

Alarm Hysteresis

Alarm hysteresis is a zone inside each alarm set point. This zone is defined by adding the hysteresis value to the alarm low set point or subtracting the hysteresis value from the alarm high set point.

An alarm state is triggered when the process value reaches the alarm high or alarm low set point. Alarm hysteresis defines how far the process must return into the normal operating range before the alarm can be cleared.

The alarm hysteresis value for output 2 can be viewed or changed with Hysteresis 2 [hYS2] (Output 2 Menu).

Process

A process alarm uses one or two absolute set points to define an alarm condition. The alarm process value of output 2 can be viewed or changed with Alarm 2 High [A2hi]

Alarm Latching

A latched alarm will remain active after the alarm condition has passed. It can only be deactivated by the user. An alarm that is not latched will deactivate automatically when the alarm condition has passed.

Alarm 2 Latching [LAt2] (Output 2 Menu) allows you to view or change whether the output 2 alarm will latch.

Clear a latched alarm by pressing the Reset key after the alarm condition has passed.

Alarm Silencing

Alarm silencing has two uses:

1. It is often used to allow a system to warm up after it has been started up. With alarm silencing on, an alarm is not triggered when the process temperature is initially lower than the alarm low set point. The process temperature has to enter the normal operating range beyond the hysteresis zone in order to activate the alarm function.

2. Alarm silencing also allows the operator to disable the alarm output while the controller is in an alarm state. The process temperature has to enter the normal operating range beyond the hysteresis zone in order to activate the alarm output function.

Alarm Silencing 2 [SiL2] (Output 2 Menu) allows you to view or change whether alarm silencing is on. If Alarm Annunciation 2 [Anu2] (Output 2 Menu) is set to [`YES], the output 2 indicator light will remain on and an alarm message will appear in the display, even though the alarm is silenced.

Watlow Series 97 Features ■ 5.11

Communications

Overview

A Series 97 controller can also be programmed and monitored by connecting it to a personal computer or programmable logic controller (PLC) via serial communications. To use this communications option, a Series 97 must be equipped with an output 4 communications board for EIA/TIA-485 (97_ _ - _ _ _U - _ _ _ _), which allows as many as 32 controllers on a 4,000-foot-long network, or EIA/TIA-232 (97_ _ - _ _ _R - _ _ _ _), which allows a single controller to be connected to a computer.

The Series 97 uses an 8-N-1 data format (eight data bits, no parity, one stop bit and one start bit).

To view or change controller settings with a personal computer, you need to run software that uses the Modbus RTU protocol to read or write to registers in the controller. These registers contain the parameter values that determine how the controller will function and the values that reflect the current input and output values of the system. The parameters chapter lists the modbus address and range for each parameter. Refer to setup parameter table for setup order.

Communications parameters appear in the Output 4 Menu (Setup Page). Match the Baud Rate [baud] to that of the computer and select an Address [Addr] for each Series 97.

The wiring chapter shows how to wire a Series 97 controller for EIA/TIA-485 or EIA/TIA232 communications.

The Appendix provides technical information about programming for Modbus RTU.

Modbus Remote Terminal Unit (RTU)

Modbus RTU enables a computer or PLC to read and write directly to registers containing the controller’s parameters. With it you could read all 141 of the controller’s parameters with five read commands.

Because of the wide array of choices available for setting up a Series 97 controller, only a subset of the prompts contain parameters in a given situation. This manual explains the interrelations between prompts. A Modbus read command response of -32000 indicates that a register is not implemented;

-32001, register not active; or -32002, not read accessible. A write command will return an exception response of 01 to indicate an illegal function, 02, illegal register; or 03, illegal data. If you try to write to an inactive prompt the controller will return an illegal data address message (02).

If you already have a software application that uses Modbus, you can simply skip to the Temperature/process Controller Prompt Table or the Modbus RTU Address Table in this chapter for the address information your program will need. The rest of this section on the Modbus provides information for writing a software application that uses Modbus.

Writing a Modbus Application

You need to code messages in eight-bit bytes, with no parity bit, one stop bit (8, n, 1). Negative parameter values must be written in twos complement format. Parameters are stored in two-byte registers accessed with read and write commands to a relative address.

Messages are sent in packets that are delimited by a pause at least as long as the time it takes to send 30 bits. To determine this time in seconds, divide 30 by your baud rate.

Because changing some parameters automatically changes or defaults other parameters, use the Complete Parameter Download Sequence table in this chapter to order write commands.

Using a controller address of 0x00 for a write command broadcasts that command to all the controllers in the network. This is a powerful feature if all the controllers on a network use all or most of the same parameters.

Packet Syntax

Each message packet begins with a one-byte controller address, from 0x01 to 0xF7. The second byte in the message packet identifies the message command: read (0x03 or 0x04); write (0x06 or 0x10); or loop back (0x08).

The next n bytes of the message packet contain register addresses and/or data. The last two bytes in the message packet contain a two-byte Cyclical

Redundancy Checksum (CRC) for error detection.

Write to a Single Register Command (0x06)

This command writes a parameter to a single register. The controller will echo back the command. An attempt to write to a read-only parameter returns an illegal data address error (0x02).

Cyclical Redundancy Checksum (CRC) Algorithm

This C routine, calc_crc(), calculates the cyclical redundancy checksum, CRC, for a string of characters. The CRC is the result of dividing the string by 0xA001. Modbus applications calculate the packet’s CRC then append it to the packet.

#define POLYNOMIAL 0xA001;

unsigned int calc_crc(unsigned char *start_of_packet, unsigned char *end_of_packet) {

unsigned int crc; unsigned char bit_count; unsigned char *char_ptr;

/* Start at the beginning of the packet */

char_ptr = start_of_packet;

/* Initialize CRC */

crc = 0xffff;

/* Loop through the entire packet */

do{

/* Exclusive-OR the byte with the CRC */

crc ^= (unsigned int)*char_ptr;

/* Loop through all 8 data bits */

bit_count = 0; do{

/* If the LSB is 1, shift the CRC and XOR the polynomial mask with the CRC */

if(crc & 0x0001){

crc >>= 1; crc ^= POLYNOMIAL;

}

/* If the LSB is 0, shift the CRC only */

else{

crc >>= 1;

}

} while(bit_count++ < 7);

} while(char_ptr++ < end_of_packet); return(crc); }

Glossary

annunciator — A visual display that uses pilot lights to indicate the former or existing condition of several items in a system.

burst fire — A power control method that repeatedly turns on and off full ac cycles. Also called zero-cross fire, it switches close to the zero-voltage point of the ac sine wave. Variable-time-base burst fire selectively holds or conducts ac cycles to achieve the desired power level. See zero cross.

calibration offset — An adjustment to eliminate the difference between the indicated value and the actual process value.

CJC — see cold junction compensation. closed loop — A control system that uses a sensor to measure a process

variable and makes decisions based on that feedback.

cold junction — see junction, cold. cold junction compensation — Electronic means to compensate for the

effective temperature at the cold junction. default parameters — The programmed instructions that are permanently

stored in the microprocessor software. derivative —

The rate of change in a process variable. Also known as rate. See PID.

derivative control (D) — The last term in the PID control algorithm. Action that anticipates the rate of change of the process, and compensates to minimize overshoot and undershoot. Derivative control is an instantaneous change of the control output in the same direction as the proportional error. This is caused by a change in the process variable (PV) that decreases over the time of the derivative (TD). The TD is in units of seconds.

Deutsche Industrial Norm (DIN) — A set of technical, scientific and dimensional standards developed in Germany. Many DIN standards have worldwide recognition.

DIN — See Deutsche Industrial Norm. droop — In proportional controllers, the difference between set point and actual

value after the system stabilizes.

duty cycle — The percentage of a cycle time in which the output is on. external transmitter power supply — A dc voltage source that powers

external devices. filter, digital (DF) — A filter that slows the response of a system when inputs

change unrealistically or too fast. Equivalent to a standard resistor-capacitor (RC) filter.

form A — A single-pole, single-throw relay that uses only the normally open (NO) and common contacts. These contacts close when the relay coil is energized. They open when power is removed from the coil.

form B — A single-pole, single-throw relay that uses only the normally closed (NC) and common contacts. These contacts open when the relay coil is energized. They close when power is removed from the coil.

form C — A single-pole, double-throw relay that uses the normally open (NO), normally closed (NC) and common contacts. The operator can choose to wire for a form A or form B contact.

Watlow Series 97 Appendix ■ A.15

hysteresis — A change in the process variable required to re-energize the control or alarm output. Sometimes called switching differential.

integral — Control action that automatically eliminates offset, or droop, between set point and actual process temperature. See auto-reset.

integral control (I) — A form of temperature control. The I of PID. See integral.

isolation — Electrical separation of sensor from high voltage circuitry. Allows use of grounded or ungrounded sensing element.

Joint Industrial Standards (JIS) — A Japanese agency that establishes and maintains standards for equipment and components. Also known as JISC (Japanese Industrial Standards Committee), its function is similar to Germany’s Deutsche Industrial Norm (DIN).

junction, cold — Connection point between thermocouple metals and the electronic instrument. See junction, reference.

junction, reference — The junction in a thermocouple circuit held at a stable, known temperature (cold junction). Standard reference temperature is 32°F (0°C).

Modbus

™

— A digital communications protocol owned by AEG Schneider

Automation for industrial computer networks. Modbus™ RTU — Remote Terminal Unit, an individual Modbus™-capable device

on a network. NEMA 4X — A NEMA specification for determining resistance to moisture

infiltration. This rating certifies the controller as washable and corrosion resistant.

on/off controller — A temperature controller that operates in either full on or full off modes.

open loop — A control system with no sensory feedback. output — Control signal action in response to the difference between set point

and process variable. overshoot — The amount by which a process variable exceeds the set point

before it stabilizes.

P control — Proportioning control. PD control — Proportioning control with derivative (rate) action. PDR control — Proportional derivative control with manual reset, used in fast

responding systems where the reset causes instabilities. With PDR control, an operator can enter a manual reset value that eliminates droop in the system.

PI control — Proportioning control with integral (auto-reset) action. PID — Proportional, integral, derivative. A control mode with three functions:

proportional action dampens the system response, integral corrects for droop, and derivative prevents overshoot and undershoot.

proportional — Output effort proportional to the error from set point. For example, if the proportional band is 20° and the process is 10° below set point, the heat proportioned effort is 50 percent. The lower the PB value, the higher the gain.

A.16 ■ Appendix Watlow Series 97

proportional band (PB) — A range in which the proportioning function of the control is active. Expressed in units, degrees or percent of span. See PID.

proportional control — A control using only the P (proportional) value of PID control.

range — The area between two limits in which a quantity or value is measured. It is usually described in terms of lower and upper limits.

rate — Anticipatory action that is based on the rate of temperature change, and compensates to minimize overshoot and undershoot. See derivative.

rate band — A range in which the rate function of a controller is active. Expressed in multiples of the proportional band. See PID.

reference junction — see junction, reference. remote — A controller that receives its set point signal from another device

called the master. remote set point — A signal that indicates the set point for the process, and is

sent from another device. reset — Control action that automatically eliminates offset, or droop, between

set point and actual process temperature. Also see integral.

automatic reset — The integral function of a PI or PID temperature controller that adjusts the process temperature to the set point after the system stabilizes. The inverse of integral.

automatic power reset — A feature in latching limit controls 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.

manual reset — 1) A feature on a limit control that requires human intervention to return the limit to normal operation after a limit condition has occurred. 2) The adjustment of a proportional control to raise the proportional band to compensate for droop.

resistance temperature detector (RTD) — A sensor that uses the resistance temperature characteristic to measure temperature. There are two basic types of RTDs: the wire RTD, which is usually made of platinum, and the thermistor, which is made of a semiconductor material. The wire RTD is a positive temperature coefficient sensor only, while the thermistor can have either a negative or positive temperature coefficient.

RTD — See resistance temperature detector. thermal system — A regulated environment that consists of a heat source,

heat transfer medium or load, sensing device and a control instrument. thermocouple (t/c) — A temperature sensing device made by joining two

dissimilar metals. This junction produces an electrical voltage in proportion to the difference in temperature between the hot junction (sensing junction) and the lead wire connection to the instrument (cold junction).

thermocouple break protection — The ability of a control to detect a break in the thermocouple circuit and take a predetermined action.

three-mode control — Proportioning control with integral (reset) and derivative (rate). Also see PID.

Watlow Series 97 Appendix ■ A.17

time proportioning control — A method of controlling power by varying the on/off duty cycle of an output. This variance is proportional to the difference between the set point and the actual process temperature.

transmitter — A device that transmits temperature data from either a thermocouple or a resistance temperature detector (RTD) by way of a two-wire loop. The loop has an external power supply. The transmitter acts as a variable resistor with respect to its input signal. Transmitters are desirable when long lead or extension wires produce unacceptable signal degradation.

WatLink — A Watlow software application for configuring and communication with Watlow controllers via a EIA-485 network and a Microsoft Windowscompatible personal computer.

zero cross — Action that provides output switching only at or near the zerovoltage crossing points of the ac sine wave. See burst fire.

zero switching — See zero cross.
