WARNING! The power controller’s protection rating is IP20 with all covers installed and closed. It must be installed in an enclosure that provides all the necessary additional protections appropriate for the environment and application.

WARNING! Ground the power controller via the provided protective earth grounding terminal. Verify ground

is within impedance specications. This should be veried periodically.

WARNING! Electric Shock Hazard: when the power controller has been energized, after shutting off the power, wait at least one minute for internal capacitors to discharge before commencing work that brings you in to contact with power connections or internal components.

WARNING! The installation must be protected by electromagnetic circuit breakers or by fuses. The semicon-

ductor fuses located inside the power controller are classied for UL® as supplementary protection for semicon-

ductor devices. They are not approved for branch circuit protection.

WARNING! When making live voltage or current measurements, use proper personal protective equipment

for the voltages and arc-ash potentials involved.

WARNING! Verify the voltage and current ratings of the power controller are correct for the application.

CAUTION: To avoid compromising the insulation, do not bend wire or other components beyond their bend

radius specications.

CAUTION: Protect the power controller from high temperature, humidity and vibrations.

CAUTION: The power controller warranty is void if the tested and approved fuses are not used.

CAUTION: Only trained and authorized personnel should access and handle the internal electronics and they

must follow proper electro-static prevention procedures.

CAUTION: Install an appropriately sized RC lter across contactor coils, relays and other inductive loads.

NOTE! Provide a local disconnect to isolate the power controller for servicing.

NOTE! The nominal current is specied for ambient temperatures at or below 40° C. Ensure the application

design allows for adequate cooling of each power controller. The power controller must be mounted vertically. The cooling design must prevent air heated by one power controller from causing power controllers mounted above to exceed the ambient operating temperature limit. When power controllers are mounted side by side allow a minimum spacing of 15mm between them.

NOTE! Use only copper cables and wires rated for use at 75°C or greater.

AVERTISSEMENT! Tous les services, y compris l’inspection, l’installation, le câblage, l’entretien, le dépan-

nage, le remplacement de fusibles ou d’autres composants pouvant être réparés par l’utilisateur, doivent être

effectués uniquement par un personnel dûment qualié. Le personnel de service doit lire ce manuel avant d’effectuer tout travail. Pendant que l’entretien est exécuté, tout personnel non qualié ne doit effectuer de travail

Installation

WARNING: To avoid damage to property and equipment, injury and loss of life, adhere to applicable electrical codes and standard wiring practices when installing and operating this product. Failure to do so could result in damage, injury and death.

Installing the ASPYRE Power Controller

This chapter provides the information necessary to select and prepare a location and to mount one or more ASPYRE power controllers.

Consider the spacing required for power, load, and control signal wiring before mounting the power controller. Take in to account the controller dimensions, wire bending radius, and cooling requirements. Use good wiring practices to minimize electrical noise problems.

Peripheral Components

Allow room for fuses and fuse holders for the auxiliary input power and fans (if present).

Mounting Orientation

Mount power controllers vertically.

Bend Radius

Allow adequate space to route cables without requiring bending more than permitted for the type of cable.

Environmental Conditions

Mount ASPYRE power controllers in a suitable electrical enclosure. Allow adequate wire bending space and cool-

ing. The maximum ambient temperature in the enclosure must not exceed 104°F (40°C).

Cooling Requirements

To maintain the ambient temperature in the enclosure in which the power controller, circuit breakers, fuses and other components are installed, there must be adequate cooling to remove the heat generated by all the devices. The power controllers are designed to be cooled by drawing cool air in from the bottom and expelling heated air at the top. Typically cabinets are designed with one or more fans on the front door or on the top of the enclosure. The designer will need to know the heat generated by the power controller. See the table below.

ductor fuses located inside the power controller are classied for UL® as supplementary protection for semicon-

ductor devices. They are not approved for branch circuit protection.

Wiring the ASPYRE Power Controller

This chapter describes how to select, prepare and attach power and signal wires to the power controller.

Good Wiring Practices

Follow good wiring practices to minimize the effects of interference from nearby equipment and the line power on the operation of the power controller:

• Install an appropriately sized RC lter across contactor coils, relays and other inductive loads

• Use shielded twisted-pair cables for input, output and communication signals

• Route control and signal cables away from motors and other sources of electromagnetic interference and not parallel to power cables

• Follow all local regulations applicable to electrical installations

NOTE: Use only copper cables and wires rated for use at 75°C or greater.

Configure the Enable Input

By default digital input 1 is used to enable the power controller.

To verify that digital input 1 is congured to enable the power controller:

• On the Hardware menu verify that Digital In 1 Function is set to Enable.

NOTE! If the power controller is used to switch power on and off simply following an on-off or time propor-

tioned signal, that signal can be connected to the enable input and the set point can be set to 100%.

Configure the Current Limit

For models with this option the current limit feature prevents the current from exceeding the user-set current limit. As the current approaches the limit, the power controller decreases its output to avoid exceeding the current limit. The current limit set point can be set with the I Limit parameter or by an analog input.

CAUTION: This procedure must be performed only by qualied persons.

CAUTION: This procedure requires turning on full power to the load. This should only be performed once the

installation is complete and when it is safe to provide full power.

NOTE! this procedure assumes the analog input signal wiring, if used has been connected and that the signal can be set to various values as needed to perform the procedure. See “Set Point, Feedback or Current Limit (Analog Input 2)” on page 26.

ATTENTION : Cette procédure ne doit être effectuée que par le personnel qualié.

Using ASPYRE Configurator

This chapter explains how to use the ASPYRE Congurator software as an alternative to using the power controller’s keypad and display for viewing and setting parameters as well as the advanced features not available via the power controller’s onboard user interface.

Overview

This section describes the scope and intent of the ASPYRE Congurator software.

Typical Uses

The software may be used during commissioning to set and make a record of settings that determine how the power controller operates and performs; to copy or clone the setup or one power controller to another; on a day-to-day basis to monitor operation and power usage; if necessary, to examine performance in more detail to determine if any corrective actions are needed; or to restore the setup of the power controller.

Communicating with Power Controllers

ASPYRE Congurator software can communicate with ASPYRE power controllers via USB or RS-485. When initially

commissioning the power controller it is convenient to connect a computer to the power controller via the USB port located below the control panel’s display. The power controller’s electronics are powered by the computer via the USB connection when the auxiliary line power is turned off. This makes it possible to examine and congure the power controller’s settings prior to applying power to the panel.

USB is designed to connect consumer electronics and peripheral devices such as cameras and keyboards to computers in home and ofce environments; it is not an industrial communications protocol. To continue communicating once the panel door is closed and line power is on, connect the computer to the power controller via the RS-485 communications port. See “Communication Connections” on page 28.

Recipes

A recipe is a computer le which contains a setting for each user adjustable parameter in a power controller. A recipe can be used to congure a power controller for a particular application or job. A recipe can be used to

copy the settings of one power controller to another. A recipe can be created by uploading the settings from a

power controller to the ASPYRE Congurator software and saving it as a le on the computer. A power controller can be congured by downloading a saved recipe from the ASPYRE Congurator software to the power controller.

How To

This section provides step-by-step procedures for common tasks.

Communicate For the First Time

These procedures are for installing the software and establishing communications for the rst time.

To install ASPYRE Congurator:

1. Locate the installer:

• On www.watlow.com linked to the ASPYRE power controller product page. Download the installer to your computer

• On the Controls Tools DVD ROM disk.

Watlow - ASPYRE 300A to 700A Power Controller • 39 • Chapter 6 Using ASPYRE Configurator

Page 40

2. Double-click the installer program.

3. Follow the on-screen instructions to complete the installation.

To communicate with a power controller:

1. For the direct USB connection:

• Connect the USB cable (Watlow p/n 0219-0480-0000) between the computer and the micro USB connector between the display and keypad on the ASPYRE power controller’s control panel.

• Wait for the USB driver to install, if necessary.

2. For an RS-485 connection:

• Connect the computer to the ASPYRE power controller. See “Communication Connections” on page 28. For most computers a USB-to-485 converter is required (Watlow p/n 0847-0326-0000).

3. Launch the ASPYRE Congurator software.

4. Select:

• ASPYRE to communicate with a single-phase power controller

• ASPYRE 3PH to communicate with a three-phase power controller (two or three switched legs)

5. From the Setting menu, choose Serial Port.

6. For Port, select the COM port that is connected to the power controller (see the note below).

7. To verify communications, click Test.

8. Click OK.

NOTE! There are several ways to determine which port is connected to the power controller. You can look in

the Windows® Device Manager under Ports (COM & LPT) for the COM port named “LPC USB VCOM Port (COMx)”

where x is the port number. You can also disconnect the USB cable from the computer, run ASPYRE Congurator and note the ports available in the list on the Serial Port dialog, then close ASPYRE Congurator, reconnect the

USB cable and run the program again; the port that did not appear previously is the correct one.

Using ASPYRE Configurator

These procedures are for using the software once communication has been set up. They assume the software has been installed and the COM port and model type (ASPYRE or ASPYRE 3PH) have already been selected.

Closed Loop Control

The ASPYRE power controller measures the voltage and current delivered to the load, and depending on how it is

congured, corrects for, among other things, variations in line voltage and load resistance.

DT1 Models and DT3 Models

Single-phase and three-phase, three-leg models that include the current limit option, use two control loops to regulate power to the load. One loop attempts to drive the output to match the power demand set point. The other loop attempts to drive the current through the load to match the current limit. By using the lesser of the outputs from the two control loops, the power is controlled to the set point but prevented from exceeding the current limit.

While the current limit loop overrides the power demand loop, the output is phase angle

red and the display

indicates the current limit alarm. If the alarm output function is set to indicate the current limit, the alarm relay is de-energized.

LOAD

Each loop adjusts its output based on its measurement of error, the difference between the set point and the measured and calculated feedback. For the current limit loop, the error is the difference between the current

Watlow - ASPYRE 300A to 700A Power Controller • 71 • Chapter 8 Features

Page 72

limit set point and the measured current. For the power demand loop, the error is the difference between the set point and the user-selected feedback. See Feedback below.

The two loops use proportional and integral (PI) control which allows them to compensate for both transient and long-term variations in conditions, including line voltage and load resistance. The performance of each loop can be tuned by adjusting the corresponding proportional band and time integral settings. The Prop Band Power and Integral Power parameters determine how the power controller adjusts its output to match the set point. The Prop Band Current and Integral Current parameters determine how the power controller adjusts the output to ensure that the current limit set point is enforced. These parameters are on the advanced setup menu.

The power demand set point can be set with the Set Point parameter on the Operator menu via the keypad or via communications. Alternatively it can be set by an analog voltage or current signal from a potentiometer or another piece of automation equipment such as a temperature controller.

DT2 Models

Three-phase, two-leg models use one control loop to regulate power to the load. The power demand loop attempts to drive the output to match the power demand set point.

The loop adjusts its output based on its measurement of error, the difference between the set point and the measured and calculated feedback. See Feedback below.

The power demand loop uses proportional and integral (PI) control which allows it to compensate for both transient and long term variations in conditions, including line voltage and load resistance. The performance of this loop can be tuned by adjusting the proportional band and time integral settings. The Prop Band Power and Integral Power parameters determine how the power controller adjusts its output to match the set point. These parameters are on the advanced setup menu.

The feedback setting determines what the power controller attempts to keep constant and therefore what variations are minimized.

Because closed-loop control reacts to the difference between the user-supplied set point and the measured feedback, the feedback selection also determines the meaning of the set point. For example, if Feedback is set to Voltage, the set point is interpreted as a percentage of the nominal load voltage. In that case, with set point at 50%, the power controller adjusts the output to make the voltage drop across the load half the Nominal V setting.

• External—the power controller adjusts the output to make the signal received as eternal feedback on analog input 2 equal to the set point.

• No Feedback—the power controller output is on for a percentage of time equal to the set point. The power demand loop does not adjust the output based on the measured voltage or current.

Keep in mind that in single-phase and 60A to 500A three-phase models, the output is limited by the current limit loop. Therefore, at times the actual output may be less than the power demand loop’s set point. See “Current Limit” on page 74.

Set the feedback on the advanced setup menu see “Feedback” on page 58. The feedback can also be set with a digital input. See “Digital Inputs” on page 74.

Current Limit

For models that include current limiting, this feature is always active. By default it limits the RMS load current by reducing the output whenever the power demand control loop would tend to drive current above the current limit set point.

You can congure the power controller to limit peak rather than RMS current. The controller limits peak current by switching to phase angle ring whenever the peak current would otherwise exceed the limit. When peak

current limiting is enabled, the current limit set point is interpreted as peak rather than RMS current. See “Limit Peak Current (Models with Current Limit)” on page 61.

Set the current limit set point, I Limit, on the setup menu. To determine the current limit set point empirically, see “Congure the Current Limit” on page 33.

Conﬁgurable Inputs and Outputs

The ASPYRE power controller features two digital inputs, up to two analog inputs and a relay output. Some models also include an analog output for retransmitting a measured value to other automation equipment. This section describes the various functions of these inputs and outputs and how they interact with other features of the power controller.

Digital Inputs

The ASPYRE power controller has two optically-isolated, digital inputs that can be connected to control panel switches or other automation equipment such as a temperature controller or programmable logic controller. See “Congurable Digital Inputs (Digital Input 1 and Digital Input 2)” on page 27 for information on connecting to the digital inputs.

Using Digital In 1 Function and Digital In 2 Function on the hardware menu each digital input can be congured to perform one of the following:

• Enable—the power output is off unless this signal is on. If both digital inputs are set to this option, the state of digital input 2 takes precedence.

• Voltage Feedback—this signal overrides the feedback setting. When this signal is on, the control loop uses voltage feedback. When the signal is off, the loop reverts to the feedback parameter setting.

• Local / Remote—this signal selects how the set point is set. When this signal is on, the control loop’s set point is set using the keypad or through communications. When this signal is off, the set point is set by the an analog input. When a digital input is set to this function, the Local/Remote (L/R) button on the front panel cannot be used to choose the source of the set point.

• Phase Angle—this signal overrides the Firing setting. When this signal is on, the power controller uses

phase-angle ring. When the signal is off, the controller uses the method set with the ring parameter on

the advanced setup menu. This option is available with single-phase and 60A to 500A three-phase models.

• SP Analog In 1 / 2—this signal chooses which of the two analog inputs is used as the source of the set point when the remote set point is in effect. When this signal is off, analog input 1 is the source of the remote set point. When the signal is on, analog input 2 is the source of the remote set point.

• Logging—this signal turns data logging on or off. When the signal is on, data is logged. When the signal is off, data is not logged. When this signal is on, it supersedes the setting of the Logging parameter on the advanced setup menu.

• Heater Bakeout—this signal turns the heater bakeout feature on or off. When the signal is on, the heater bakeout feature is enabled. When the signal is off, the heater bakeout feature is disabled. When this signal is on, it supersedes the setting of the Heater Bakeout parameter on the advanced setup menu. This option is available with single-phase and 60A to 500A three-phase models.

To congure how the power controller uses these signals, see “Digital In 1 Function” on page 56 and “Digital In 2 Function” on page 57.

Analog Input 1: Set Point

To control the power to the load with a device such as a temperature controller, connect the control signal to analog input 1.

This input accepts current, voltage and potentiometer signals. The signal is interpreted as set point by comparing the measured value to the input’s full scale. For example, the set point is 50% when the analog input detects

5V and the input is congured to receive 0 to 10VDC.

Congure the power controller to recognize the signal with the hardware menu; see “Analog In 1 [Signal Type]”

on page 53. For instructions for wiring this input see “Set Point (Analog Input 1)” on page 26.

Analog Input 2: Set Point, Feedback or Current Limit Set Point

What this input does is user-congurable. Connect an analog signal that indicates:

• An alternate set point signal

• Measured power, voltage or current from an external device used as feedback

• Maximum current to the load (current limit) in single-phase and 60A to 500A three-phase models

This input accepts current, voltage and potentiometer signals. The signal is interpreted by comparing its measured value to the input’s full scale. For example, the signal is 50% when the analog input detects 12mADC and

the input is congured to receive 4 to 20mADC.

Congure the power controller to recognize the signal and how the power controller uses it on the hardware

menu; see “Analog In 2 [Signal Type]” on page 54 and “Analog In 2 Function” on page 54. For instructions for wiring this input see “Set Point, Feedback or Current Limit (Analog Input 2)” on page 26.

Choose which conditions determine the alarm relay output with the Alarm Function setting on the hardware menu. See “Alarm Function” on page 53.

NOTE! The alarm relay output indicates an alarm

Firing Types

This section describes the options for the Firing parameter. Using the correct ring ensures the optimum perfor- mance of the power controller with a particular type of load. Set Firing on the advanced setup menu.

Zero-Crossing

This ring type is used with relatively slow loads and when

it is desirable to minimizing radio frequency emissions by switching only as the line voltage crosses zero volts. Power

to the load is on for a percentage of the xed time-base

proportional to the required output percentage. The time base is dened by the Cycle Time parameter. For example, if the cycle time is ten seconds and 75% power is called for, the output turns on for 7.5 seconds and off for 2.5 seconds, and repeats.

The illustration shows examples of zero-cross ring with a

cycle time of 10 seconds:

• 25%, the output is on for 2.5 out of every 10 seconds

(150 out of 600 cycles at 60Hz)

• 50%, the output is on for 5 out of every 10 seconds

(300 out of 600 cycles at 60Hz)

• 75%, the output is on for 7.5 out of every 10 seconds

(450 out of 600 cycles at 60Hz)

• 100%, the output is on continuously

Contactor Operation

Off

The power controller can be congured to switch power on

and off following a signal from, for example, a temperature controller’s output. In this case, power to the load is on when the signal from the temperature controller to the power controller’s digital input is high, and off when the signal is low. The power controller is said to operate as a contactor. When controlled by a device such as a temperature controller, any time proportioning is determined by

that device, not the power controller. In this conguration

the power controller’s power demand loop does not adjust the output or use feedback, but in single-phase and 60A to 500A three-phase models the current limiting loop is active and will reduce power delivered to ensure current does not exceed the limit.

Though the output is said to follow the enable input, power to the load is actually switched on or off only at the voltage zero cross in order to minimize radio frequency emissions.

With single-cycle ring, power to the load is on for a number cycles proportional to the required output percentage.

The illustration shows examples of single-cycle ring:

• 75%, the output is on for three out of every four cycles

This ring type is similar to burst ring, however, the

addition of the start ramp feature causes the output to be

at the beginning of each burst. This intermittent phase-an-

gle ring increases radio frequency emissions compared with purely zero-cross switching ring types. This ring

type is recommended for use with small inductive loads to avoid inrush current.

The illustration shows examples of burst ring with four

• 25%, the output ramps up for three and is on for one full cycle out of every sixteen

The illustration shows examples of burst ring with two

minimum cycles and a delay of 50 degrees applied to one half-cycle:

• 25%, the output turns on at 50° and remains on for the remainder of two out of every eight cycles

• 66%, the output turns on at 50° and remains on for the remainder of two out of every three cycles

• 100%, the output turns on at 50° and remains on continuously

NOTE! Do not use this ring type with transformer-coupled loads that have low resistances when cold, such

as heaters with silicon carbide, molybdenum and tungsten elements. Instead consider using phase-angle ring.

Delayed triggering increases radio frequency emissions compared with purely zero-cross switching ring types.

Other than the programmable delay, this ring method is similar to burst ring. The load switches on for a num-

ber cycles proportional to the required output percentage. The output is on and off for at least the user-speci-

ed number of cycles.

Phase Angle with Soft Start (DT1 and DT3 Models)

This ring type is the same as Phase Angle except it does use the soft start feature. Whenever the set point is

changed, the ring angle is gradually adjusted rather than

being instantaneously changed. The set point is ramped from the previous set point to the new set point over the user-set Soft Start Time which is set in 50ms increments on the advanced setup menu.

The soft start feature also applies when the enable signal turns on. For example if the set point is 60% but the enable signal is off, when the enable signal turns on, the output gradually increases as if the set point was ramped up from 0% to 60% over the soft start time. However, when the enable signal turns off, unlike the case of lowering the set point, the output turns off immediately rather than ramping down.

This ring type is recommended to reduce inrush current with transformers during the cycle of magnetization or with cold resistance loads that are nearly short circuits when they are rst turned on.

The soft start feature can be used with all ring types except Phase Angle. Soft start acts as a lter on the set

point gradually applying changes to the set point over the user-set soft start time. The soft start time is set in 50ms increments on the advanced setup menu.

The soft start feature also applies when the enable signal changes state. For example, if the set point is 60% but the enable signal is off, when the enable signal turns on, the output gradually increases as if the set point was ramped up from 0% to 60% over the soft start time setting.

NOTE! When the ring type is set to Phase Angle, the soft start feature is ignored. To use soft start with

phase angle, set the ring type to Phase Angle Soft Start.

Start Ramp (DT1 and DT3 Models)

Start ramp causes the output to be phase-angle red for a user-specied number of half cycles each time the output is turned on. This intermittent phase-angle ring increases radio frequency emissions compared with purely zero-cross ring types. Set the duration of the ramp using the Start Ramp parameter on the advanced set-

up menu in increments of half cycles.

Safety Ramp (DT1 and DT3 Models)

Bakeout SP 100%

This feature is the same as start ramp except it is active only if the output is off for longer than a user-set time.

Safety ramp can be used with single-phase and 60A to 500A three-phase models using burst ring with delay or half cycle ring. Use it to ramp up the voltage applied to a heater or other load which has been off for more

than a user set time.

With this option enabled, after power to the load has been off for more than the user-set time, once power is

called for, the ring type is temporarily changed to phase angle and the power is ramped up from zero to the set point over the safety ramp time. Once the ramp is complete, the ring type reverts to the user setting.

Because it uses phase-angle ring, safety ramp increases radio frequency emissions when active compared with

purely zero-cross switching.

Enable the safety ramp feature and set how long the ramp takes by setting the Safety Ramp Duration (#66) to a value greater than zero (in increments of 50ms). Set the minimum amount of time the power to the load is off before the ramp occurs with the Safety Ramp O Time parameter in increments of 50ms (#65).

Heater Bakeout Function (Models with Current Limit)

When a heater insulated with magnesium oxide (MgO) is powered off, not in use or in storage for a long period of time, it can absorb moisture. If full power is applied, excessive current can damage the heater or blow fuses. The heater bakeout feature limits the voltage and current applied as the heater is brought back in to service. This drives moisture out of the heater and prevents blown fuses and damage to the heater.

Using Heater Bakeout

While the heater bakeout feature is active, the ASPYRE power controller ramps the current according to the user-set current and ramp time parameters for the heater bakeout function. The heater bakeout function does not ramp the output above the normal process set point. Once the function has run for the user-set time, the bakeout function terminates and the power controller attempts to perform control to set point normally.

Use Heater Bakeout Ramp Time to set the duration of the bakeout in minutes. Use Heater Bakeout Current to set the current to which the function attempts to ramp in Amperes. Use Heater Bakeout Off Time to set how many minutes the heater can be off before the bakeout fuction runs the next time the heater is used.

While the performing the heater bakeout function, the power controller displays a message.

Totalizer

The ASPYRE power controller includes a power totalizator that sums the power over time in various terms. The total power over time can be viewed on the ASPYRE Con-

gurator PC software’s Test view.

Data Logging

The ASPYRE power controller offers an optional data logging feature. Record up to ten parameters as often as

once per second. Use ASPYRE Congurator software to set the real-time clock, to select which parameters to log, to retrieve data log les and to manage the logging memory. See “Setting Up and Using Data Logging” on

page 42. The ASPYRE Congurator software also supports viewing the data in log les after downloading them from the power controller.

Data logging can be turned on and off using:

• ASPYRE Congurator software (see “Setting Up and Using Data Logging” on page 42.)

• The advanced setup menu in the power controller’s user interface (see “Logging” on page 61)

• A digital input (see “Digital In 1 Function” on page 56, “Digital In 2 Function” on page 57 and “Digital Inputs” on page 74)

Maintenance & Troubleshooting

This chapter describes the routine maintenance that should be planned, provides information for troubleshooting and includes procedures for corrective actions.

NOTE! To ensure proper and safe operation of the equipment all investigation, adjustments and replacement

procedures must be performed by qualied individuals.

REMARQUE : Pour assurer un fonctionnement approprié et sécuritaire de l’équipement, toutes les recherch-

es, les réglages et les procédures de remplacement doivent être effectués par le personnel qualié.

Routine Maintenance

With very little maintenance you can expect the ASPYRE power controller to provide years of trouble-free operation.

1. To prevent overheating, periodically clean the heat-sink and protective grill on the fans. Depending on the environment, this cleaning may be necessary more or less frequently.

2. Periodically verify the torque on the bolts for the line, power and safety earth ground connections.

Alarms and Indicators

This section describes the alarms that can occur and what can cause them.

Alarm Indicator

When an alarm occurs and while the condition persists, the indicator labeled "4" on the display is lit. The indicator is normally off.

Aux High ALARM

Alarm Relay Output

When an alarm occurs and while the condition persists, the alarm relay is de-energized. The alarm relay is energized when power is supplied to the controller’s electronics via the auxiliary power input and there are no alarms. The alarm relay can be congured to indicate various combinations of alarms using the hardware menu see “Alarm Function” on page 53.

Alarms and Messages

The display normally indicates the power demand set point and one of the home page parameters such as output

current. When an alarm or other condition occurs and while the condition persists, the upper display ashes the

corresponding message. See the table below and the following sections for descriptions of each.

Alarms and Messages

Alarm or Message DT1 DT2 DT3 Description

Aux High X X X Aux voltage too high Aux Line Loss X X X Auxiliary power is not detected Aux Low X X X Aux voltage too low Bakeout X X Heater bakeout function is active Heater Break X X X Heater break alarm I Limit X X Output reduced by current limit feature PH Loss X X One or more phases of the line power are disconnected SD Card Error X X X SD card error SCR Short X X X Shorted SCR (output on continuously) SCR Over Temp X X X Thermal switch over temperature Unbalance Load X X One or more legs of the load are open Watchdog X X X Communication watchdog error

Aux High

This alarm occurs when the auxiliary voltage is over the maximum required. Verify the auxiliary power requirement per the model number.

Aux Line Loss

This alarm is indicated when the line power is off, but the electronics are powered by another means, such as the USB port or the optional 24VDC input.

Aux Low

This alarm occurs when the auxiliary voltage is below the minimum required. Verify the auxiliary power requirement per the model number.

Bakeout

The heater bakeout feature is controlling the output. See “Heater Bakeout Function (Models with Current Limit)” on page 83.

Heater Break Alarm

This alarm occurs when the measured load resistance is higher than expected. See “Heater Break Calibration Procedure” on page 90.

I Limit

In models with the current limit option this alarm indicates when the current loop overrides the power demand loop to prevent the load current from exceeding the current limit set point. In DT3 models this alarm indicates when the current exceeds the user-set current limit. DT1 and DT3 models reduce the output to enforce the limit; DT2 models do not. For more information see “Current Limit” on page 74.

Watlow - ASPYRE 300A to 700A Power Controller • 86 • Chapter 9 Maintenance & Troubleshooting

Page 87

PH Loss

One or more phases of the line power are disconnected.

SD Card Error

This error occurs when the SD memory card option is present but does not work properly or when it is impossible to read or write data. Contact your supplier.

SCR Short

This alarm occurs when the SCR is stuck on and the output is on continuously.

Thermal Switch

This alarm occurs when the temperature sensor on the power switch indicates it is too hot. The thermal switch alarm triggers the alarm relay output. Until the temperature is reduced, power to the load is turned off. Correct the environmental conditions that caused the over temperature or reduce the load current to resume operation.

Operating the unit at temperatures outside the specied range can void the warranty. For information on proper

cooling see “Cooling Requirements” on page 18.

Unbalanced Load

The resistance of one or more legs of the load has gone outside the tolerance for a balanced load. The alarm indication specifies which leg of the load is outside the tolerance. This likely indicates one or more legs of the

load are open.

Watchdog

This error occurs when the communications watchdog feature is enabled but no transmission has been received for longer than the user-set watchdog reset time. When this error occurs, power to the load is turned off. See “Watchdog” on page 69 and “Watchdog Reset Time” on page 69.

Removing the Covers

WARNING: To prevent injury and loss of life, shut off power and ensure it cannot be

restored while performing work with the covers open or removed.

CAUTION: Take appropriate precautions to prevent electrostatic discharges from damag-

ing electronic components when handling the boards.

AVERTISSEMENT : Pour éviter les blessures et les pertes de vie, couper l’alimentation électrique et s’assurer qu’elle ne peut être restaurée pendant l’exécution du travail avec les couvercles ouverts ou enlevés.

Replacement Fuses

The ASPYRE power controller contains fast-blow fuses protecting the SCR power switches. These fuses are critical to safe operation of the power controller particularly in preventing catastrophic failure in the event of a shorted load. The agency approvals are contingent upon the use of the same fuses (manufacturer and model) that were tested. The table below lists the tested and approved fuses for the various models.

CAUTION: These fuses protect life and property against catastrophic failure in the event of a shorted load.

They do not provide and are not approved for branch circuit protection.

CAUTION: The power controller warranty is void if the tested and approved fuses are not used.

WARNING: Before opening the cover, disconnect and lock out the line power and control signals to the unit

and verify that power and control cables are isolated from voltage sources.

ATTENTION : Ces fusibles protègent la vie et la propriété contre des pannes catastrophiques en cas de

charge en court-circuit. Ils n’assurent aucune protection des circuits de dérivation et ne sont pas approuvés à

cette n.

ATTENTION : La garantie du régulateur de puissance est nulle si aucun fusible testé et approuvé n’est util-

isé.

AVERTISSEMENT : Avant d’ouvrir le couvercle, débrancher et verrouiller les signaux d’alimentation de ligne

et de commande, puis vérier que les câbles d’alimentation et de commande sont isolés des sources de tension.

Calibration Procedures

The procedures in this section can be used to adjust the performance of the corresponding features.

Configure the Current Limit

The current limit feature acts to prevent the RMS current from exceeding the user-set current limit. As the current approaches the limit, the power controller decreases its output. The current limit set point can be set with the I Limit parameter or by an analog input.

CAUTION: This procedure must be performed only by qualied persons.

CAUTION: This procedure requires turning on full power to the load. This should only be performed once the

installation is complete and when it is safe to provide full power.

ATTENTION : Cette procédure ne doit être effectuée que par le personnel qualié.

Watlow - ASPYRE 300A to 700A Power Controller • 89 • Chapter 9 Maintenance & Troubleshooting

Page 90

ATTENTION : Cette procédure nécessite la mise sous tension totale de la charge. Cela ne doit être effectué

qu’une fois l’installation terminée et lorsque la puissance maximale peut être fournie en toute sécurité.

For help with entering and accessing the menus see “Menu Navigation” on page 36.

To limit the current using the parameter setting:

1. On the Hardware menu set I Limit Local / Remote to Local.

2. On the Operator menu set the I Limit to 0%.

3. Enable the power controller and set the power demand / set point to 100%.

4. Gradually increase the current limit set point until the RMS current is at the maximum desired value.

5. Disable the power controller.

To limit the current using the signal to analog input 2:

1. On the Hardware menu set Analog In 2 for the type of signal and range:

0 to 10 VDC or 10k potentiometer

4 to 20 mADC

0 to 20 mADC

3. On the Hardware menu set the Analog In 2 Function to I Limit.

4. On the Hardware menu set the I Limit Local / Remote to Analog In 2.

5. Set the signal to the analog input to the minimum value (typically 0 V).

6. Enable the power controller and set the power demand / set point to 100%.

7. Gradually increase the signal to the analog input until the RMS current is at the maximum desired value.

8. Disable the power controller.

NOTE! This procedure assumes the analog input signal wiring, if used has been connected and that the signal

can be set to various values as needed to perform the procedure. See “Set Point (Analog Input 1)” on page 26.

Heater Break Calibration Procedure

The heater break alarm is automatically set when you set the nominal load current and nominal line voltage. If the load resistance increases due to a partial or total load failure, the heater break alarm occurs.

You can adjust the resistance threshold at which the heater break alarm occurs with the Htr Break Sensitivity parameter on the advanced setup menu. This parameter is set as a percent of the nominal load resistance (from 1% to 100%). A lower value causes the alarm to occur with less change to the resistance.

For example, if the nominal line voltage is 300V and the nominal load current is 3A, the nominal load resistance

is 100Ω. With the heater break sensitivity set to 20%, the heater break alarm occurs if the measured load resistance rises above 120Ω.

If the heater break alarm occurs due to transient conditions, you can suppress these nuisance alarms by increasing the Htr Break Delay parameter.

CAUTION: To work properly the load must be powered at least about 160msec.

NOTE! The minimum current is 10% of the current transformer size. If the load current is below this value,

the Heater Break Alarm does not work properly.

ATTENTION : Pour fonctionner correctement, la charge doit être alimentée à au moins 160 m/s.

Communication

Overview

This chapter describes using the various options for communicating between an ASPYRE power controller and third-party devices and software.

Wiring

For information about wiring for the communication ports see “Communication Connections” on page 28.

Data Types

Each memory register contains an unsigned, 16-bit integer value. In a few cases the values from more than one register must be combined to read a single parameter value. For example, the kW Total parameter is stored in two 16-bit registers which must be combined in to a 32-bit long for display to users. These cases are indicated in

the tables found later in this chapter. Any protocol specic types are indicated in the corresponding section.

Implied Decimals and Linear Scaling

Some values must be scaled from the units of measure in which they are displayed before being transmitted to the power controller, and conversely when read from the power controller via communications, these values must be scaled to the units of measure for display to users.

In some cases the value read via communications must be divided by a factor of ten because decimal precision is implied. For example, Frequency is measured and stored with two decimal place accuracy, but is transmitted via Modbus® TCP as a whole number with two implied decimal places.

In other cases the value read via communication must be scaled linearly from the range over which it is stored in the power controller to the range of values in the units of measure presented to the user. For example, the Set Point range 0% to 100% is stored in the power controller as value that ranges from 0 to 1023. When the set point is 50% the value read from the power controller is 511, not 500.

In all cases the necessary scaling is indicated in the tables found later in this chapter.

Enumerated Values

Some values represent data that is indicated by a word or short phrase. These enumerated values are listed in the tables found later in this chapter. For more thorough explanations see the parameter descriptions in the “Parameter Reference” chapter starting on page 53.

Bitwise Values

The Status Bits parameter indicates the states of alarms, digital inputs and other features with bits that correspond to each state. The Command Bits parameter supports switching features such as local or remote current limit on or off. For more details see “Status Bits” on page 68 and “Command Bits” on page 55.

To set a command bit without making other changes, read the command bits register, then write the value corresponding to the current setting with the one bit of interest changed.

Communication Watchdog

While a host device or software is connected via Modbus® TCP, Probus DP or Pronet, the ASPYRE power controller must receive a message from the master at least once every 35 seconds. If the time between messages

Watlow - ASPYRE 300A to 700A Power Controller • 97 • Chapter 10 Communication

Page 98

exceeds this limit and when the connection is closed, the parameters in the holding registers are all set to zero (0) to ensure the unit is in a safe state. This feature does not apply to Modbus® RTU or EtherNet/IP™.

To disable this watchdog feature and control the power controller locally, disable the secondary communications. See “Port 2 Access” on page 64.

Enabling the Secondary Port

In order to be able to write parameter settings from the host to the ASPYRE power controller via the secondary communications port (port 2), you must set the Port 2 Access parameter to Read and Write. Do this using ASPYRE

Congurator software or on the communication menu using the power controller’s built-in user interface.

Ethernet Network Setup

In order to establish communications, congure the Ethernet port in the ASPYRE power controller for your network. The IP address can be set only via the web page served by the ASPYRE power controller. View the current

network settings for the power controller on the communication menu or using ASPYRE Congurator.

Modbus® TCP

This section describes communicating with an ASPYRE power controller via the Modbus® TCP communication option. The typical application for this protocol is using a programmable logic controller or other automation equipment to control the power controller.

Features

The Modbus® TCP option supports the following features.

Broadcast Messages

The ASPYRE power controller supports Modbus® TCP broadcast messages. Send broadcast messages using station address 0. All ASPYRE power controllers on the local area network act on the message contents without sending back any reply.

NOTE! When the Command Bits parameter is set to zero, the Set Point Source and I Limit Local / Remote parameters are each set to accept signal from the analog inputs. If the application normally uses the secondary communication port to set the Set Point and I Limit values, the Command Bits parameter must be initialized accordingly each time the master connects to the power controller.

Supported Functions

The ASPYRE power controller supports the Modbus® TCP functions listed below.

Function Description

04 Read the input registers (30,001 to 39,999) 03 Read the holding registers (40,001 to 49,999) 06 Write a single holding register 16 Write multiple holding registers

EtherNet/IP™ Setup

This section describes communicating with an ASPYRE power controller via the EtherNet/IP™ communication option. The typical application for this protocol is using a programmable logic controller or other automation equipment to control the power controller.
