Watlow’s EZ-ZONE PM controllers offer options to reduce system complexity and the cost of control-loop ownership. You can order the EZ-ZONE PM as a PID controller or an over-under limit controller, or you can combine both functions in the PM Integrated Limit Controller. You now have the option to integrate a high- amperage power controller output, an over-under limit controller and a high-performance PID controller all in space-saving, panel-mount packages.

Page 52 Communication Protocols When using a communications protocol in conjunction with the EZ-ZONE PM there are two possible ports (instances) used. Port 1 or instance 1 is always dedicated to Standard Bus communications. This same in- stance can also be used for Modbus RTU if ordered. Depending on the controller part number port 2 (in- stance 2) can be used with Modbus, CIP and Profibus.
Page 53 Modbus Introduction to the Modbus Protocol (cont.) All Modbus registers are 16-bits and as displayed in this User's Guide are relative addresses (actual). Some legacy software packages limit available Modbus registers to 40000 to 49999 (5 digits). Many applica- tions today require access to all available Modbus registers which range from 400000 to 465535 (6 digits). For parameters listed as float, notice that only one (low order) of the two registers is listed;...

Page 124: Changing Pm Integrated Model Number To Pm Express
Changing PM Integrated Model Number to PM Express EZ-ZONE PM firmware revisions of 13 and above allow the user to switch between a PM Integrated control to a PM Express. Switching to a PM Express eliminates the complexity of the advanced PM Integrated con- trol by allowing the user to operate with a simplified menu structure.
Page 125: How To Change The Control Model Number To A Pm Express
How to Change the Control Model Number to a PM Express 1. Enter Factory Page [FCty ] , Calibration Menu [`CAL] via front panel or using EZ-ZONE Configurator Software. 2. Once there, using the green advance button navigate to the Part Number [``Pn] prompt (lower display). The upper display will show factory [ fCtY] indicating the factory model number as shown on the side of the control is currently in effect.
Page 126: Tuning The Pid Parameters
When restoring factory defaults, I/O assemblies for Modbus, DeviceNet, Profibus and Ethernet along with the zone address will be overwritten when restoring factory defaults. Tuning the PID Parameters Autotuning ® When an autotune is performed on the EZ-ZONE PM, the set point is used to calculate the tuning set point. For example, if the active set point is 200°...
Page 127: Autotuning With Tru-Tune
Manual Tuning (cont.) 5. 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.
Page 128: Inputs
ç 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 . Inputs Calibration Offset Calibration offset allows a device to compensate for an inaccurate sensor, lead resistance or other factors that...
Page 129: Filter Time Constant
Note: The user may only calibrate one sensor type. If the calibrator interferences with open thermocouple detec- tion, set Sensor Type [`SEn] in Setup Page [`SEt], Analog Input Menu [``Ai] to millivolt [`Mu] instead of Thermocouple [``tC] to avoid interference between the calibrator and open thermocouple detect circuit for the duration of the calibration process.
Page 130: Sensor Selection
Sensor backup maintains closed-loop control after an input failure by switching control to input 2. The sensor backup feature is only available in an EZ-ZONE PM Integrated Limit or Remote Set Point controller. Turn sensor backup on or off with Sensor Backup Enable [`S; b A] (Setup Page, Analog Input 1).
Page 131: Outputs
12 to 4mA (0 to -100 percent). In some cases this type of output is required by the device that the EZ-ZONE PM 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 sig- nal.
Page 132: No-Arc Relay
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.
Page 133: Resetting A Tripped Limit
Cool Output Curve A nonlinear output curve may improve performance when the response of the output device is nonlinear. If a cool output uses one of the nonlinear curves a PID calculation yields a lower actual output level than a linear output would provide.
Page 134: Control Methods
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.
Page 135: On-Off Control

Page 137: Variable Time Base
Dead Band (cont.) 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. When the dead band value is a negative value, both heating and cooling outputs are active when the tem- perature is near the set point.
Page 138: Single Set Point Ramping
Variable Time Base (cont .) 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 elec- tromechanical relays, mercury displacement relays, inductive loads or heaters with unusual resistance char- acteristics.
Page 139: Alarms
Differential Control The PM can be configured for Differential Control with enhanced firmware. After configuring the appropri- ate inputs and their associated internal functions Differential Control allows the PM to drive an output based on the difference between those analog inputs. See Chapter 10 for application examples.
Page 140: Alarm Hysteresis
If the EZ-ZONE PM 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. Turn alarm blocking on or off with Blocking [`A;...
Page 141: Current Sensing
Current Sensing When utilizing the Current Sensing capabilities of this control it is important to know that the measure- ments taken utilize the AC Line Frequency [AC; l f] setting found in the Global Menu of the Setup Page. If this setting does not represent the incoming line frequency of this control the readings will be in error and may appear to be frozen.
Page 142: Using Lockout And Password Security
Using Lockout and Password Security If unintentional changes to parameter settings might raise safety concerns or lead to downtime, you can use the lockout feature to make them more secure. There are two methods of lockout that can be deployed, both of which are accessible from the Factory Page.
Page 143: Using Lockout Method 2 (Password Enable)
Although the Factory Page is always visible, some menus within it can be restricted. Lockout Security [SLoC] & [rloC] Factory Page Menus Security Level Menus Custom Menu Lockout Menu* Diagnostic Menu** Calibration Menu * Using lockout Method 1 with [SLoC] set to 0, all writable parameters within the control will be inhibited (not writable) with two exceptions, [sloC] and [rloC] .
Page 144 The Administrator can either change the User and or the Administrator password or leave them in the de- fault state. Once Password Security is enabled they will no longer be visible to anyone other than the Ad- ministrator. In other words the Lock Menu [`loC] is not available to a User. As can be seen in the formula that follows either the User or Administrator will need to know what those passwords are to acquire a high- er level of access to the control.
Page 145: Modbus - Using Programmable Memory Blocks
Modbus - Using Programmable Memory Blocks When using the Modbus RTU or Modbus TCP protocols, the PM control features a block of addresses that can be configured by the user to provide direct access to a list of 40 user configured parameters. This allows the user easy access to this customized list by reading from or writing to a contiguous block of registers.

O (Target to Originator) and the O to T (Originator to Target) assemblies where the Target is always the EZ-ZONE PM controller and the Originator is the PLC or master on the network. The size of the O to T as- sembly is initially set to 20 (32-bit) members where the T to O assembly consists of 21 (32-bit) members.
Page 147: Profibus Dp - (Decentralized Peripherals)
Profibus DP - (Decentralized Peripherals) This protocol is typically used to operate sensors and actuators via a centralized controller within industrial- ized production topologies. Data rates up to 12 Mbit/s on twisted pair cables and/or fiber optics are possible. This protocol is available in three functionally graded version; DP-V0, DP-V1 and DP-V2. It should be noted that Watlow products utilizing this protocol support DP-V0 and DP-V1 only.
Page 148: Searching Network For Devices
If the PC is already physically connected to the EZ-ZONE PM control click the next button to go on-line. Note: When establishing communications from PC to the EZ-ZONE PM control an interface converter will be re- quired. The Standard Bus network uses EIA-485 as the interface. Most PCs today would require a USB to EIA-485 converter.
Page 149 The PM8 is shown highlighted to bring greater clarity to the control in focus. Any EZ-ZONE device on the network will appear in this window and would be available for the purpose of configuration or monitoring; simply click on the control of choice. After doing so, the screen below will appear. In the screen shot below no- tice that the device part number is clearly displayed at the top of the page (yellow highlight added for empha- sis).
Page 150 Although the PM control now contains the configuration (because the previous discussion focused on doing the configuration on-line) it is suggested that after the configuration process is completed that the user save this file on the PC for future use. If for some reason someone inadvertently changed a setting without understanding the impact, it would be easy and perhaps faster to download a saved configuration back to the control versus trying to figure out what was changed.
Page 151: Chapter 10: Applications
Chapter 10: Applications Example 1: Single Loop Control Requirements: One input is required and at least one output adjusts the controlled part of the process. Overview: Controls one process value to a user entered Closed Loop Set Point based on an control algorithm. Control loop 1 will control Analog Input 1 to Closed Loop Set Point 1.
Page 152: Example 3: Square Root
Example 3: Square Root Requirements: One analog input and the enhanced software option are required and at least one output adjusts the controlled part of the process. Overview: Calculates the square root value of the sensor connected to Analog Input 1. When function is set for Square Root, the PV Function output equals square root value of Source A.
Page 153: Example 5: Differential
Example 5: Differential Requirements: Two analog inputs and the enhanced software option are required and at least one output adjusts the controlled part of the process. Overview: Differential control maintains one process at a difference to another process. When function is set for Differential, the PV Function output equals Source A minus Source B.
Page 154 The graph below illustrates a system with a long lag time and the advantages in using cascade control. Curve A represents a single-control system with PID parameters that allow a maximum heat-up rate. Too much energy is introduced and the set point is overshot. In most long-lag-time systems the process value may never settle out to an acceptable error.
Page 155: Example 7: Wet Bulb / Dry Bulb
Example 7: Wet Bulb / Dry Bulb Requirements: Two analog inputs and at least one output are required to adjust the controlled part of the processes. Overview: Wet Bulb/Dry Bulb Wet Bulb/Dry Bulb is a configuration where a dry bulb connected to Analog Input 1 measures tem- perature on Analog Input 1.
Page 156: Example 9: Motorized Valve Control
Example 9: Motorized Valve Control A typical scenario where a motorized valve is used is to regulate the flow of fluid which in turn impacts the loop process value. A valve is opened or closed by closing contacts to drive the value in the intended direction. Motor- ized Valves come in a number of configurations.
