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 con- troller, or you can combine both functions in the PM Integrated 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.

See model number information in the Appendix for more information. If there is only one instance of a menu, no submenus will appear. Profile Setup First, consider some foundational profile setup features that once configured, will apply to all configured profiles.
Once these global profile features are configured, the next step will require navigation to the Profiling Page. Here, each desired ramp and soak profile will be configured. To navigate to the Profile Page from the front panel, follow the steps below: 1.

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 Inte- grated control to a PM Express. Switching to a PM Express eliminates the complexity of the advanced PM Integrated control by allowing the user to operate with a simplified menu struc- ture.
After switching the model number to a PM Express this document will no longer apply to the control. Click on the link that follows to acquire the latest version of the PM PID Ex- press User's Guide. http://www.watlow.com/en/Resources-And-Support/Technical-Library/ User-Manuals Once there, simply enter express in the "Keyword" field to find the appropriate document.
Time has no affect. A new feature in EZ-ZONE PM products will allow set point changes while the control is autotuning, this includes while running a profile or ramping. When the auto tune is initially started it will use the current set point and will disregard all set point changes until the tun- ing process is complete.
at the normal set point, using the new parameters. Select a set point for the tune with Autotune Set Point. The Autotune Set Point is expressed as a percent of the Set Point. If you need to adjust the tuning procedure's aggressiveness, use Autotune Aggressiveness (Setup Page, Loop Menu).
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 com- pensate for differing control characteristics at various set points for processes that are not entirely linear.
Calibration 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 differ- ence to the published accuracy Negative Calibration Offset will compensate for the difference...

Note: The user may only calibrate one sensor type. If the calibrator interferes with open ther- mocouple detection, set Sensor Type in Setup Page , Analog Input Menu millivolt instead of Thermocouple to avoid interference between the calibrator ЛЏ u and open thermocouple detect circuit for the duration of the calibration process.
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.
Or you could use an analog output from a PLC to send set point values to an EZ-ZONE PM. The controller must have two process inputs to use the remote set point feature.
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 signal.
The Watlow NO-ARC relay is a hybrid relay. It uses a mechanical relay for the current load and a triac (solid-state switch) to carry the turn-on and turn-off currents. NO-ARC relays extend the life of the relay more than two million cycles at the rated full-load current.
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. These output curves are used in plastics extruder applications: curve A for oil-cooled extrud- ers and curve B for water-cooled extruders.

control can be selected with Heat Algorithm or Cool Algorithm (Setup Page, Loop h. a g C. a g Menu). On-off hysteresis can be set with On/Off Heat Hysteresis or On/Off Cool Hyster- h. h y esis (Operations Page, Loop Menu). C.
Proportional, Integral and Derivative (PID) Control Use derivative (rate) control to minimize the overshoot in a PI-controlled system. Derivative (rate) adjusts the output based on the rate of change in the temperature or process value. Too much derivative (rate) will make the system sluggish. Adjust the derivative with Time Derivative (Operations Page, Loop Menu).
Dead Band (cont .) When the dead band value is a negative value, both heating and cooling outputs are active when the temperature is near the set point. Adjust the dead band with Dead Band (Op- erations Page, Loop Menu). Negative Dead Band Cool Output Active Set Point...
Single Set Point Ramping Ramping protects materials and systems that cannot tolerate rapid temperature changes. The value of the ramp rate is the maximum degrees per minute or hour that the system tem- perature can change. Select Ramp Action (Setup Page, Loop Menu): ramping not active.
On - When Source B Value <= Input B Turn On To prevent unwanted on/off cycling and compressor wear, there are two settings (On and Off Time) that allow the user to define how fast a compressor may be turned off and back on again.

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 con- trol loop.
The process temperature has to enter the normal operating range beyond the hysteresis zone to activate the alarm function. 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.

All of these prompts can be found in the Operations Page under the Current Menu. CT Application Note: Alarms have to point to the correct source for the current measurement.
Using Lockout and Password Security If unintentional changes to parameter settings might raise safety concerns or lead to down- time, 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. Method 1- Change the value of the Read Lock (1 to 5) and Set Lock (0 to 5)

Modbus - Using Programmable Memory Blocks When using the Modbus RTU or Modbus TCP protocols, the PM control features a block of ad- dresses that can be configured by the user to provide direct access to a list of 40 user config- ured parameters.
PM control. Watlow refers to these assemblies as the T to O (Target to Originator) and the O to T (Origi- nator to Target) assemblies where the Target is always the EZ-ZONE PM controller and the Originator is the PLC or master on the network.
This protocol is typically used with older Allen Bradley programmable controllers capable of PLC-5 compatibility. EZ-ZONE PM controllers support this protocol. As described above, the PM has 2 assemblies; one for input (O to T), and the other for output (T to O). Within the PM controller and as viewed and accessed using Rockwell software, these assemblies can be identified as N11:0 (O to T) and N10:0 (T to O).
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 ver- sion; DP-V0, DP-V1 and DP-V2. It should be noted that Watlow products utilizing this protocol support DP-V0 and DP-V1 only.
