PM PLUS™ Operational Overview

The PMPLUS receives Information from an input, performs an internal function as a response to that input, then causes a resulting output. All of these - the inputs, the internal functions, and the outputs - are conﬁgurable. A single PM PLUS™ can carry out several functions at the same time, such as PID control, checking for a limit condition, monitoring for several alarm situations, etc.

You may conﬁgure up to four proﬁles to automate a sequence of up to ten steps per proﬁle, to further customize and extend the application of the device.

Inputs

Inputs provide the information a programmed procedure can act upon. A basic example is a sensor monitoring the temperature of a part being heated or cooled. Each analog input typically uses a thermocouple or RTD to read the process temperature or the volts, current or resistance from various devices.

Optional digital input/output (DIO) hardware can be used as either an input or an output. Each DIO must be conﬁgured as either an input or output. A digital input allows for a speciﬁc function to occur. The Function Key can also be programmed to allow for a speciﬁc function to occur.

Internal Functions

A function is a user-programmed internal process that uses input signals to calculate a value and then perform an action, i.e.:

• Compare an input value to the set point and calculate the optimal power for a heater

• Detect a failure of the primary sensing device and trip a contactor to remove power from the heating element

• When a digital input signal changes, allows for a speciﬁc function to occur.

• Evaluate an incoming temperature to determine an alarm state (on or off)

Each internal function is associated with one source, or instance. For example, a control equipped with DIO, can be conﬁgured to respond to one of the four alarms.

Outputs

Outputs are functions or actions conﬁgured to respond to information provided by an internal function. Some output examples are: removal of the control voltage to a contactor; operating a heater, turning a light on or off, unlocking a door, etc.

You can assign outputs to any input, and may assign more than one output to respond to a single instance of a function. For example, alarm 2 could be used to trigger a light connected to output 1 and a siren connected to DIO 5.

Configuration and Monitoring of Features Through Lists

PM PLUS™ features and parameters are structured in lists that you can access via the smooth-touch key interface on the front panel for easy conﬁguration and monitoring. You can also access lists remotely if you prefer, using our EZ-LINK app or our CONFIGURATOR software.

List Description

Operations List This list is used to monitor or change runtime settings such as the high set point of the

limit, or monitor things like the time remaining in a proﬁle step. It is also used to access the main conﬁguration lists referenced here.

Setup List This is used prior to operation to set up equipment related settings such as input type

and output cycle time.

Proﬁle List If equipped with this feature you will use this list to conﬁgure up to 4 proﬁles with up to

ten steps each.

Factory List This list doesn't affect runtime operations. It is used to adjust hardware settings like

passwords or the appearance of the Home Screen, or to view the control part number.

Profiles

A proﬁle is a sequence of steps. When a proﬁle runs, the controller automatically executes its steps in sequence. The step type determines what action the controller performs. Steps can change temperatures and other process values gradually over time, maintain temperatures and process values for speciﬁc periods, or repeat a sequence of steps numerous times. At each step the proﬁle can activate or deactivate outputs that control other equipment. Also a step can have the controller wait for speciﬁc conditions before proceeding such as, waiting for a switch closure and/or a speciﬁc process value to be detected by a sensor.

Input Events and Output Events

When a Proﬁle step is programmed as a "Wait For Event Input" will wait for the "Input Event" to be in the proper state before it will proceeds to the next step of a Proﬁle. Event Outputs will allow you to turn "On" or "Off", or "leave as is"; in each step of a Proﬁle.

Using Watlow Software to Configure Parameters

You can set up all parameters directly from the PM PLUS™ front panel via the Setup List, as explained in this manual, or use Watlow CONFIGURATOR or COMPOSER on a PC. If you choose to use Watlow CONFIGURATOR or COMPOSER software to set up the PM PLUS™ from your PC, you'll need to wire communications (see Chapter 2). There are two ports (instances) for communications. Port 1 is dedicated to Standard Bus communications. Port 1 may also be used for Modbus

You can conﬁgure up to four proﬁles in the PM PLUS. Once conﬁgured, you can start any of the four proﬁles manually from the Operations - Proﬁle list. You may wish to conﬁgure the function key to start a speciﬁc proﬁle, or set up a DIO to start a proﬁle.

Setting Up Global Features

Some feature settings, once conﬁgured, apply to all proﬁles, e.g. if Guaranteed Soak is not enabled in the Global List, this feature will not be available in any individual proﬁle. These parameters apply to all proﬁles:

You must set up the globally applicable parameter settings prior to setting up individual profiles.

2. Select a parameter using the right arrow key, and select the desired option for that parameter. After selecting the parameter, press the left back arrow to return to the Global List and choose the next parameter so you can conﬁgure its options.

• Ramping Type can be Time or Rate, and defaults to Time. If set to time, the set point is ramped according to the

time interval selected (hours minutes, seconds). If set to rate, the set point is ramped by degrees/units per minute.

• Profile Type can be Set Point or Process. This determines whether a step changing the set point of a profile be-

gins using the last closed-loop set point (Set Point). or the process value (Process)

• Guaranteed Soak Enable, when set to on is available in all profiles. If Guaranteed Soak Enable is on, use Guaran-

teed Soak Deviation 1 to 2 for the corresponding loop. Set the deviation or band above or below the working set point where this condition must be met before the profile can proceed.

• Source Instance A and Source instance B refer to DIO 5 or 6, and are used in "Wait for Event" steps.

Autotune

When an autotune is performed on the PM PLUS™ the set point is used to calculate the tuning set point. For example, if the active set point is 200° and Autotune Set Point is 90 percent, the autotune function uses 180° for tuning.

Autotuning calculates the optimum heating and/or cooling PID parameter settings based on the system's response. The PID settings generated by the autotune will be used until the autotune feature is rerun, the PID values are manually adjusted or TRU-TUNE+

2. Scroll to select

3. Use the slider or +/- keys to set the set point for the tune.

4. Press the Home icon to return to the Home Screen.

WARNING! During autotuning, the controller sets the output to 100 percent and attempts to drive the Process Value toward the

set point. Enter a set point and heat and cool power limits that are within the safe operating limits of your system.

Manual Tuning

In some applications, the autotune process may not provide PID parameters for the process characteristics you desire. If that is the case, you may want to tune the controller manually.

8. Start with an Integral value of 6,000 and allow 10 minutes for the process temperature to reach the set point. If it has not, reduce the setting by half and wait another 10 minutes. Continue reducing the setting by half every 10 minutes until the process value equals the set point. If the process becomes unstable, the Integral value is too small. Increase the value until the process stabilizes.

TRU-TUNE+

The TRU-TUNE+ adaptive algorithm optimizes the controller's PID values to improve control of dynamic processes. TRU-TUNE+ monitors the Process Value and adjusts the control parameters automatically to keep your process at set point during set point and load changes. When in adaptive control mode, the controller determines the appropriate output signal and, over time, adjusts control parameters to optimize responsiveness and stability. The TRU-TUNE+

feature does not function for on-off control.

The preferred and quickest method for tuning a loop is to establish initial control settings and continue with the adaptive mode to ﬁne tune the settings. Setting Control Mode to tune starts this two-step tuning process. This predictive tune determines initial, rough settings for the PID parameters. Then the loop automatically switches to the adaptive mode which ﬁne tunes the PID parameters.

Once the Process Value has been at set point for a suitable period (about 30 minutes for a fast process to roughly two hours for a slower process) and if no further tuning of the PID parameters is desired or needed, TRU-TUNE+™ may be turned off. However, keeping the controller in the adaptive mode allows it to automatically adjust to load changes and compensate for differing control characteristics at various set points for processes that are not entirely linear.

Once the PID parameters have been set by the TRU-TUNE+ adaptive algorithm, the process, if shut down for any reason, can be restarted in the adaptive control mode.

Enable TRU-TUNE+ only after autotune is complete. TRU-TUNE+ should be disabled before autotune is initiated.

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 offset value can be viewed or changed with Calibration Offset (Operations — Setup -

Analog Input).

Before performing any calibration procedure, verify that the displayed readings are not within published speciﬁcations by inputting a known value from a precision source to the analog input. Next, subtract the

displayed value with the known value and compare this difference to the published accuracy range speciﬁcation for that type of input.

Equipment required while performing calibration:

Obtain a precision source for millivolts, volts, milliamperes or resistance depending on the sensor type to be calibrated. Use copper wire only to connect the precision source to the controller’s input. Keep leads between the precision source and controller as short as possible to minimize error. In addition, a precision volt/ohm meter capable of reading values to 4 decimal places or better is recommended. Prior to calibration, connect this volt/ohm meter to the precision source to verify accuracy. Actual input values do NOT have to be exactly the recommended values, but it IS critical that the actual value of the signal connected to the controller be accurately known to at least four digits.

Go to Operations — Setup — Control Loop — to enter the Minimum Set Point and Maximum Set Point.

Scale High and Scale Low

When an analog input is selected as process voltage or process current input, you must choose the low and high values of voltage or current. For example, when using a 4 to 20 mA input, the scale low value would be

4.00 mA and the scale high value would be 20.00 mA. Commonly used scale ranges are: 0 to 20 mA, 4 to 20

mA, 0 to 5V, 1 to 5V and 0 to 10V. You can create a scale range representing other units for special applications. You can reverse scales from

high values to low values for analog input signals that have a reversed action. For example, if 50 psi causes a 4 mA signal and 10 psi causes a 20 mA signal.

Scale low and high low values do not have to match the bounds of the measurement range. These along with range low and high provide for process scaling and can include values not measurable by the controller. Regardless of scaling values, the measured value will be constrained by the electrical measurements of the hardware.

Range High and Range Low

With a process input, you must choose a value to represent the low and high ends of the current or voltage range. Choosing these values allows the controller’s display to be scaled into the actual working units of measurement. For example, the analog input from a humidity transmitter could represent 0 to 100 percent relative humidity as a process signal of 4 to 20 mA. Low scale would be set to 0 to represent 4 mA and high scale set to 100 to represent 20 mA. The indication on the display would then represent percent humidity and range from 0 to 100 percent with an input of 4 to 20 mA.

Remote Set Point

A remote set point can be received with two process inputs (analog or J1939), using a thermocouple, RTD, 1 k potentiometer or process signal at input 2 to establish the set point. A common application would use one ramping controller with a set-point retransmit output to ramp multiple controllers using the remote set point. Or you could use an analog output from a PLC to send set point values to a PM PLUS.

You may select between local and remote set points at the front panel, with an event input, from a remote computer using the communications feature or from an external switch using an event input. Make sure all input and output impedances are compatible.

Ten Point Linearization

The linearization function allows a user to re-linearize a value read from an analog input. There are 10 data points used to compensate for differences between the sensor value read (input point) and the desired value (output point). Multiple data points enable compensation for non-linear differences between the sensor readings and target process values over the thermal or process system operating range. Sensor reading differences can be caused by sensor placement, tolerances, an inaccurate sensor or lead resistance.

Output Features

Duplex

Certain systems require that a single process output, control both heating and cooling outputs. A PM PLUS™ with a process output can function as two separate outputs. With a 4 to 20mA output the heating output will operate from 12 to 20mA (0 to +100 percent) and the cooling output will operate from 12 to 4mA (0 to -100 percent).

In some cases this type of output is required by the device the PM PLUS™ controls, such as a three-way valve that opens one way with a 12 to 20mA signal and opens the other way with a 4 to 12mA signal. This feature reduces the overall system cost using a single output to act as two outputs.

Outputs 1 and 3 can be ordered as process outputs. Select duplex as the Output Function (Setup Page, Output Menu). Set the output to volts or milliamps with Type. Set the range of the process output with Scale Low and Scale High.

NO-ARC Relay

A NO-ARC relay provides a signiﬁcant improvement in the life of the output relay over conventional relays. Conventional mechanical relays have an expected life of 100,000 cycles at the rated full-load current. The shorter life for conventional relays is due to the fact that when contacts open while current is ﬂowing metal degradation occurs. This action produces unavoidable electrical arcing causing metal to transfer from one contact to the other. The arcing conditions continue on each subsequent contact opening until over time the resistance through the contacts increases causing the contacts to increase in temperature. Eventually, the contacts will weld together and the relay remains in the on state.

The Watlow NO-ARC relay is a hybrid that uses a mechanical relay for the current load and a triac (solidstate switch) to carry the turn-on and turn-off currents. NO-ARC relays extend the life of the relay more than

Watlow PM PLUS™ 6 • 85 • Chapter 8: Features

Page 86

two million cycles at the rated full-load current. Although a NO-ARC relay has signiﬁcant life advantages, a few precautions must be followed:

Do not use:

• Hybrid relays for limit contactors. A limit or safety device must provide a positive mechanical break on all hot legs simultaneously

• DC loads with hybrid relays. The triacs used for arc suppression will turn off only with ac line voltage

• Hybrid switches to drive any inductive loads, such as relay coils, transformers or solenoids

• Cycle times less than five seconds on hybrid switches

• On loads that exceed 264V ac through relay

• On loads that exceed 15 amperes load

• On loads less than 100mA

• NO-ARC relays in series with other NO-ARC relays

Retransmitting a Process Value or Set Point

Applicable on models with a Universal Process output 1 and 3. Check your product label to confirm the configuration code shows F in the 6th or 10th digit: PM _ _ _ [F] _ - _ _ [F] _ _ _ _ .

The retransmit feature allows a process output to provide an analog signal that represents the set point or process value. The signal may serve as a remote set point for another controller or as an input for a chart recorder documenting system performance over time.

Outputs 1 and 3 can be ordered as process outputs. To conﬁgure these outputs, go to Operations — Setup

— Output — Output [1,3] — Function — and select Retransmit. Set the output to volts or milliamps with Type. Select the signal to retransmit with Retransmit Source. Set the range of the process output with Scale Low and Scale High. Scale the retransmit source to the process output with Range Low and Range High.

In choosing the type of retransmit signal, consider the input impedance of the device to be retransmitted to and the required signal type, either voltage or milliamps. Typically applications might use the retransmit option to record one of the variables with a chart recorder or to generate a set point for other controls in a multi-zone application.

When the retransmit source is at the Range Low value, the retransmit output will be at its Scale Low value. When the retransmit source is at the Range High value, the retransmit output will be at its Scale High value.

Resetting a Tripped Limit

Applicable on Integrated Limit models. Check your product label to confirm the configuration code shows L or M in the 9th digit: PM _ _ _ _ _ - _ [L,M] _ _ _ _ _.

On Limit models, output 4 is a Form A (normally open) Mechanical Relay and it is internally tied to the limit function. When the limit is in a safe state the internal coil for this relay is energized, and the relay will be closed. When a condition causes the limit to trip, the internal coil de-energizes, causing the relay to latch open. When the condition that caused the limit to trip is within the limit range, plus the hysteresis value; the relay remains latched open until manually reset by an operator.

Reset a Tripped Limit (Use one of these four methods)

1. When at the Home Page, and a Limit condition occurs; then "Attention Limit" will appear. It will also state "Press Home to Request Clear".

2. Set Source Function A to the device that will reset the limit (Digital I/O or Function Key).

3. Use a ﬁeld bus protocol, i.e., Modbus®, EtherNet/IP™, etc. and write a value of zero to the associated address (navigate to the Operations List — and look for Clear Limit under the Limit Menu to ﬁnd appropriate address).

4. Cycle the power to the controller.

Control Methods

Output Configuration

Each controller output can be conﬁgured as a heat output, a cool output, an alarm output or deactivated. No dependency limitations have been placed on the available combinations. The outputs can be conﬁgured in any combination. For instance, all three could be set to cool.

Heat and cool outputs use the set point and Operations parameters to determine the output value. All heat and cool outputs use the same set point value. Heat and cool each have their own set of control parameters. All heat outputs use the same set of heat control parameters and all cool outputs use the same set of cool output parameters.

Each alarm output has its own set of conﬁguration parameters and set points, allowing independent operation.

Auto (closed loop) and Manual (open loop) Control

The controller has three modes of operation: auto, manual, and off. Auto mode allows the controller to decide whether to perform closed-loop control or to follow the settings

of Input Error Failure. The manual mode only allows open-loop control. The PM PLUS™ is normally used in the auto mode. The manual mode is usually only used for specialty applications or for troubleshooting.

Manual mode is open-loop control that allows the user to directly set the power level to the controller’s output load. No adjustments of the output power level occur based on temperature or set point in this mode.

Off deactivates the control loop and all outputs attached to the control loop are turned off. In auto mode, the controller monitors the input to determine if closed-loop control is possible. The

controller checks to make certain a functioning sensor is providing a valid input signal. If a valid input signal is present, the controller will perform closed-loop control. Closed-loop control uses a process sensor to determine the difference between the process value and the set point. Then the controller applies power to a control output load to reduce that difference. If a valid input signal is not present, the controller will indicate an input error message on the Home Screen and respond to the failure according to the setting of Input Error Failure. You can conﬁgure the controller to perform a bumpless transfer, switch power to output a preset ﬁxed level, or turn the output power off.

Bumpless Transfer

Bumpless transfer allows the controller to transfer to manual mode using the last power value calculated in auto mode if the process had stabilized at a ±5 percent output power level for the time interval or 10 seconds, (whichever is longer) prior to sensor failure, and that power level is less than 75 percent. Reverse Bumpless functionality will take effect when the control is changed from Manual to Auto mode. The control will preload the Manual Power value into the Integral and Proportional Terms, which will allow for a bumpless transition. The normal PID action will then take over to control the output to the Set Point value.

Input Error Latching (Operations — Setup -— Analog Input — [on,off]) determines the controller’s response once a valid input signal returns to the controller.

• If latching is on, the controller will indicate an input error until the error is cleared. To clear a latched alarm, press the Home icon as indicated on the screen.

• If latching is off, the controller will automatically clear the input error and return to reading the temperature. If the controller was in the auto mode when the input error occurred, it will resume closed-loop control.

• If the controller was in manual mode when the error occurred, the controller will remain in open-loop control. The Manual Control Indicator Light % is on when the controller is operating in manual mode.

On-Off Control

On-off control switches the output either full on or full off, depending on the input, set point and hysteresis values.

The hysteresis value indicates the amount the process value must deviate from the set point to turn on the output. Increasing the value decreases the number of times the output will cycle. Decreasing hysteresis improves controllability. With hysteresis set to 0, the process value would stay closer to the set point, but the output would switch on and off more frequently, and may result in the output “chattering.”

On-off control can be selected with Heat Algorithm (Operations — Setup - Control Loop - Heat Algorithm) or Cool Algorithm (Operations — Setup - Control Loop - Cool Algorithm). Then, On/Off hysteresis can be set at

Operations — Setup - Control Loop - On/Off Heat Hyster. or Operations — Setup - Control Loop - On/Off Cool Hyster..

Input Error failure mode does not function in on-off control mode. The output goes off.

Proportional and (P) Control

Some processes need to maintain a temperature or process value closer to the set point than on-off control can provide. Proportional control provides closer control by adjusting the output when the temperature or process value is within a proportional band. When the value is in the band, the controller adjusts the output based on how close the process value is to the set point. The closer the process value is to the set point, the lower the output power. This is similar to backing off on the gas pedal of a car as you approach a stop sign. It keeps the temperature or process value from swinging as widely as it would with simple on-off control. However, when the system settles down, the temperature or process value tends to “droop” short of the set point.

With proportional control, the output power level equals the set point minus the process value divided by proportional band times 100. In an application with one output assigned to heating and another assigned to cooling, each will have a separate proportional parameter. The heating parameter takes effect when the process temperature is lower than the set point, and the cooling parameter takes effect when the process temperature is higher than the set point.

Adjust the proportional band with Heat Proportional Band or Cool Proportional Band (Operations — Setup -

Control Loop).

Proportional and Integral (PI) Control

The droop caused by proportional control can be corrected by adding integral (reset) control. When the system settles down, the integral value is tuned to bring the temperature or process value closer to the set point. Integral determines the speed of the correction, but this may increase the overshoot at startup or when the set point is changed. Too much integral action will make the system unstable. Adjust the integral with Time Integral (Operations — Setup - Control Loop).

Dead Band

In a PID application the dead bands above and below the set point can save an application’s energy and wear by maintaining process temperature within acceptable ranges.

Proportional action ceases when the process value is within the dead band. Integral action continues to bring the process temperature to the set point. Using a

positive dead band value keeps the two systems from

ﬁghting each other.

When the dead band value is zero, the heating output activates when the temperature drops below the set point, and the cooling output switches on when the temperature exceeds the set point.

Variable Time Base

Variable time base is the preferred method for controlling a resistive load, providing a very short time base for longer heater life. Unlike phase-angle ﬁring, variable-time-base switching does not limit the current and voltage applied to the heater. With variable time base outputs, the PID algorithm calculates an output between 0 and 100%, but the output is distributed in groupings of three ac line cycles. For each group of three ac line cycles, the controller decides whether the power should be on or off. There is no ﬁxed cycle time since the decision is made for each group of cycles. When used in conjunction with a zero cross (burst ﬁre) device, such as a solid-state power controller, switching is done only at the zero cross of the ac line, which helps reduce electrical noise (RFI). Variable time base should be used with solid-state power controllers, such as a solid-state relay (SSR) or silicon controlled rectiﬁer (SCR) power controller. Do not use a variable time base output for controlling electromechanical relays, mercury displacement relays, inductive loads or heaters with unusual resistance characteristics.

Compressor Control

The PM PLUS can be conﬁgured for Compressor control with two loops of control and enhanced ﬁrmware, as frequently used for cooling and/or dehumidiﬁcation. The application may have one or two loops of control that utilize the compressor for cooling and/or dehumidiﬁcation (negative power levels). Because the compressor is a mechanical device, it is desirable to minimize unwanted starts and stops. Either loop can attempt to start or stop the compressor, but this algorithm will determine when it should or should not run. Because you may not turn the compressor off until the loop is in the heat or humidify region, the input values (Source Function A and B) to the compressor algorithm must be loop power (+/- 100%).

The compressor turns on and off under the following conditions:

Loop 1 Off - When Source A Value >= Input A Turn Off On - When Source A Value <= Input A Turn On

Loop 2 Off - When Source B Value >= Input B Turn Off On - When Source B Value <= Input B Turn On

To prevent unwanted on/off cycling and compressor wear, set the Minimum On Time and Minimum Off Time for the compressor.

The Time Delay setting is used to avoid having the compressor remain on indeﬁnitely if the loop control modes are set to off, such as when a proﬁle ends. The rule for the Time Delay setting follows:

Off - Source A Value and Source B Value = 0.0% for a period longer than Time Delay

Differential Control

The PM can be conﬁgured for Differential Control with two inputs and enhanced ﬁrmware. After conﬁguring the appropriate inputs and their associated internal functions Differential Control allows the PM to drive an output based on the difference between those analog inputs. See

Application examples.

Ratio Control

The PM PLUS can be conﬁgured for Ratio control with two inputs and enhanced ﬁrmware, especially useful in applications that mix materials. Ratio control is commonly used to ensure that two or more ﬂows are kept at the same ratio even if the ﬂows are changing. See

Application examples.

Duplex Control

Certain systems require that a single process output controls both heating and cooling outputs. A PM PLUS with a process output can function as two separate outputs.

With a 4 to 20mA output the heating output, for instance, will operate from 12 to 20mA (0 to +100%) and the cooling outputs will operate from 12 to 4mA (0 to -100%). In some cases this type of output is required by the device, such as a three-way valve that opens one way with a 12 to 20mA signal and opens the other way with a 4 to 12mA signal. This feature reduces the overall system cost using a single output to act as two outputs.

Alarms

Alarms are activated when the output level, process value or temperature leaves a deﬁned range. A user can conﬁgure how and when an alarm is triggered, what action it takes and whether it turns off automatically when the alarm condition is over. Conﬁgure alarm outputs in the Setup Page before setting alarm set points. Alarms do not have to be assigned to an output. Alarms can be monitored and controlled through the front panel or using software.

Process and Deviation Alarms

A process alarm uses one or two absolute set points to deﬁne an alarm condition. A deviation alarm uses one or two set points that are deﬁned relative to the set point used by the control loop. High and low alarm set points are calculated by adding or subtracting offset values from the set point used by the control loop. If the set point changes, the window deﬁned by the alarm set points automatically moves with it. Select the type with Type (Setup Page, Alarm Menu).

Set Points

The high set point deﬁnes the process value or temperature that will trigger a high side alarm. The low set point deﬁnes the temperature that will trigger a low side alarm. For deviation alarms, a negative set point represents a value below set point used by the control loop. A positive set point represents a value above the set point used by the control loop. View or change alarm set points with Low Set Point and High Set Point (Operations Page, Alarm Menu).

Hysteresis

Temperature

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

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

To view or change hysteresis Operations — Setup — Alarm — Alarm [1,2,3,4] — Hysteresis — and enter the value to be added to the low set point, or subtracted from the high set point.

Silencing Alarms

If silencing is on you can disable the alarm output while the controller is in an alarm state. The process value or temperature has to enter the normal operating range beyond the hysteresis zone to activate the alarm output function again. An active message, such as an alarm message, will cause the display to toggle between the normal settings and the active message on the Home screen display.

To enable alarm silencing, go to Operations — Setup — Alarm — Alarm [1,2,3,4] — Silencing — [Off,On],

NOTE: If silence is on, and you silence with Home Key, the message is cleared, but the warning symbol remains.

Blocking Alarms

Blocking allows a system to warm up after it has been started up. With blocking on, an alarm is not triggered when the process temperature is initially lower than the low set point or higher than the high set point. The process temperature has to enter the normal operating range beyond the hysteresis zone to activate the alarm function. If the PM PLUS has an output that is functioning as a deviation alarm, the alarm is blocked when the set point is changed, until the process value re-enters the normal operating range.

To enable alarm silencing, go to Operations — Setup — Alarm — Alarm [1,2,3,4] — Blocking — and then select the desired blocking option: [Off,Startup,Set Point,Both],

Current Sensing

The measurements taken for current sensing use the AC Line Frequency setting found at Operations —

Global — AC Line Frequency — [50Hz,60Hz]. If this setting does not represent the incoming line frequency

of this controller the readings will be in error and may appear to be frozen.

If an alarm is configured to monitor current, the low alarm is effective only when the current level is equal to or greater than 2mA. If there is no current present, the low alarm will not be activated.

Open and Shorted Load Circuit Detection

A Current Error C.Er (Operations Page, Current Menu) can detect either an open or shorted load condition. A shorted condition would be present if the control is calling for 0% power while current is detected as ﬂowing through the current transformer. Conversely, an open condition would be present when the control is calling for power with no current ﬂow detected through the transformer.

A Heater Error indicates if the load current ﬂow is within the speciﬁed limits set by the user through the Current Set Points (High Set Point and Low Set Point) at Operations — Current.

Read and monitor the real-time current level through the Load Current RMS prompt while the most recent faults can be read via the Current Error and Heater Error prompts. All of these prompts can be found in the Operations Page under the Current Menu.

Watlow PM PLUS™ 6 • 98 • Chapter 8: Features

Page 99

CT Application NOTE: Alarms have to point to the correct source for the current measurement. We have one measurement that is sampled and held CU.r. Since this is a zero cross device, in zero cross the current is going to 0 each time the output is turned off. We also calculate an Current RMS value that takes into account on time versus off time. Be sure alarms are pointed to the current that is sampled and held or anytime the PID power gets low like less than 2%, the alarm will activate or if the outputs are off such as control mode set to OFF.

Open Loop Detection

When Open Loop Detection is enabled, the controller will look for the power output to be at 100%. Once there, the control will then begin to monitor the Open Loop Detect Deviation as it relates to the value entered for the Open Loop Detect Time. If the speciﬁed time period expires and the deviation does not occur, an Open Loop Error will be triggered. Once the Open Loop Error condition exists the control mode will go off and an Open Loop message will be display. If the process value goes in the opposite direction, a Reversed Loop message is displayed. The sensor is likely wired in reverse polarity.

All prompts identified in this section can be found in the Loop Menu of the Setup Page.
