Chapter 1: Overview

Introduction

Watlow’s PM PLUS™ has an intuitive interface with a smooth touch keypad for easy programming and readability. This reduces complexity at the front of the control. Using Composer or Conﬁgurator is highly desirable to program the PM. The PM PLUS™ is compatible with legacy EZ-ZONE PM controllers and connects via Bluetooth ordered in the Part number.

The PM PLUS™ can be ordered as a PID controller or an integrated controller with multiple functions combined. Look for the device conﬁguration code on the product label to conﬁrm which functional options are included on your device. Upon power up, you can see the ﬁrmware revision and Bluetooth the device display and if Bluetooth

Watlow PM PLUS™ 6 • 10 • Chapter 1 Overview

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.

Watlow PM PLUS™ 6 • 11 • Chapter 1 Overview

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.

Installing the Device

1. Make the panel cutout using the measurements shown here. We recommend a minimum of 21.6 mm between panel cutouts.

2. Remove the green terminal connectors and the mounting collar assembly.

3. Insert the controller into the panel cutout from the front.

4. Orient the collar base so the ﬂat side faces front and the screw openings are on the sides, then slide the base over the back of the controller.

5. Slide the mounting bracket over the controller with the screws aligned to the collar base.

6. Push the bracket gently but ﬁrmly until the hooks snap into the slots in the case.

7. Tighten the two #6-19 x 1.5" screws with a Phillips screwdriver until the device is ﬂush to the panel (3 to 4 in-lbs torque).

8. Secure screws from the back with Philips screwdriver.

Reinstall the terminal connectors to their original locations. (Or ﬁrst connect ﬁeld wiring as indicated in this guide and then reinstall the connectors).

• This equipment is suitable for use in Class 1, Div. 2, Groups A, B, C and D or Non-Hazardous locations only. Temperature Code T4A. Note: Class 1, Div 2 is only valid if the last 2 characters in the part # are "12".

In this example the Quencharc circuit (Watlow part# 0804-0147-0000) is used to protect PM internal circuitry from the counter electromagnetic force from the inductive user load when de-engergized. It is recommended that this or an equivalent Quencharc be used when connecting inductive loads to PM outputs.

Wiring Notes

Maximum wire size termination and torque rating:

0.0507 to 3.30 mm2 (30 to 12 AWG) single-wire termination or two 1.31 mm2 (16 AWG)

0.56 Nm (5.0 in-lb.) torque

Adjacent terminals may be labeled differently depending on the model number.

Do not connect wires to unused terminals.

Maintain electrical isolation between analog input 1, digital inputoutputs, switched dc/ open collector outputs and process outputs to prevent ground loops.

This equipment is suitable for use in CLASS I, DIVISION 2, Groups A, B, C and D or Non-Hazardous locations only. Temperature Code T4A

Wiring Warnings

ç

Use National Electric (NEC) or other countryspecic standard wiring and safety practices when wiring this controller to a power source, electrical sensors or peripheral devices. Failure to do so may result in damage to equipment and property, and/or injury or loss of life.

Explosion Hazard - Dry contact closure Digital Inputs shall not be used in Class I Division 2 Hazardous Locations unless switch used is approved for this application.

Explosion Hazard – Substitution of component may impair suitability for CLASS I, DIVISION 2.

Explosion Hazard - Do not disconnect while the circuit is live or unless the area is known to be free of ignitable concentrations of ammable substances.
