1 Chapter 1: Overview Available EZ-ZONE RM System Literature and Resources Document Title and Part Number Description EZ-ZONE Rail Mount Access (RMA) User's Guide, part number: 0600-0072-0000 Describes how to connect the RM system into an industrial network, how to use data logging, module backup and the real-time clock. EZ-ZONE Rail Mount Controller (RMC) User's Guide, part number: 0600-0070-0000 The RMC module is an advanced integrated controller capable of PID and limit control.
Introduction grated solution that minimizes inter-module connections and potential problems at screw termination points. The EZ-ZONE ® Rail Mount Expansion module (RME) takes the pain out of adding I/O points to your RM system architecture. It just got a whole lot easier to solve the thermal requirements of your system. The RME module is provided in a space-saving, rail-mount package and is highly scalable where you only pay for what you need.

A Conceptual View of the RM System The flexibility of the RM system software and hardware allows for a large range of configurations. Focusing on the RME module, acquiring a better understanding of its overall functionality and capabilities while at the same time planning out how this module can be used will deliver maximum effectiveness in your application.
that instance alone that will be reset. RMC module - The logic block (within the RME module) is configured as an OR function - The RME output function is tied to the internal output of the logical OR function Note: Alarms will reset automatically when the condition that caused the alarm goes back to a non-alarm state if the alarm latching prompt is set to non-latching (Setup Page, Alarm Menu).
A Conceptual View of RM Hardware Configurations Due to the scalability and flexibility in the system components a user has several options available in the way that the hardware can be connected. Listed below are a few examples. RM System Connected to a Remote User Interface (RUI) and a PC In this configuration the RUI and PC are connected to the RM system via Watlow's Standard Bus where both will be able to talk directly to any interconnected system module.
Module Orientation The picture below represents one of six possible RM modules. All six will have four slots on the face (slot A, B, D, and E) and one on the bottom (slot C) not shown. All of these slots are not always used on all modules. On the face of the module there is a button (white circle) under the Zone address (5) that when pushed and held has the following functions: 1.For any module, push and hold for ~ 2 seconds. The address will intensify indicating that it can now be changed.

RME Installation and Removal on a DIN Rail Modular Backplane Connector The picture on the right shows the Modular Backplane Connector, both front and rear view. The rear view is bringing in to focus a metal clip. If the DIN rail is grounded the Modular Backplane Connector and the module connected to it will be also (recommended).
Module Removal To remove a module from the Modular Backplane Connector find the red tab protruding from the bottom of the module and pull back on it as shown to the right. While pulling back on the red tab the two mounting posts will release the module where the module can then be lifted up and out of the Modular Backplane Connector.

Saving and Restoring User Settings Temperature Input Point 10 Recording setup and operations parameter settings for future reference is very important. If you unintentionally change these, you will need to program the correct settings back into the controller to return the equipment to operational condition. After you program the controller and verify proper operation, use User Settings Save [USr;S] (Setup Page, Global Menu) to save the settings into either of two files in a special section of memory.
switches the compressor on and off. The compressor will not turn on until the output power exceeds the Compressor On % Power for a time longer than the Compressor On Delay. The compressor will not turn off until the output power exceeds the Compressor Off % Power for a time longer than the Compressor Off Delay.
Process Alarms A process alarm uses one or two absolute set points to define an alarm condition. Select the alarm type [`A;ty] via the Setup Page, Alarm Menu. Alarm Set Points The alarm high set point defines the process value or temperature that will trigger a high side alarm. The alarm low set point defines the temperature that will trigger a low side alarm. For deviation alarms, a negative set point represents a value below closed loop set point.
Alarm Blocking Alarm blocking allows a system to warm up after it has been started up. With alarm blocking on, an alarm is not triggered when the process temperature is initially lower than the alarm low set point or higher than the alarm high set point. The process temperature has to enter the normal operating range beyond the hysteresis zone to activate the alarm function.
The following examples show how the Lockout Menu parameters may be used in applications: 1. You can lock out access to the Operations Page but allow an operator access to the Profile Menu, by changing the default Profile Page and Operations Page security levels. Change Lock Operations Page [LoC;o] to 3. If Set Lockout Security [SLoC] is set to 2 or higher and the Read Lockout Security [rLoC] is set to 2, the Home Pages can be accessed, and all writable parameters can be written to.
push the Advance key ‰ to proceed to the Password [ pass] prompt. If not find your way back to the Factory Page as described above. 4. Execute the calculation defined below (7b or 8b) for either the User or Administrator. 5. Enter the result of the calculation in the upper display play by using the Up ¿ and Down ¯ arrow keys or use EZ-ZONE Confgurator Software. 6. Exit the Factory Page by pushing and holding the Infinity ˆ key for two seconds.
Software Configuration use. Using EZ-ZONE® Configurator Software To enable a user to configure the RME module using a personal computer (PC), Watlow has provided free software for your use. If you have not yet obtained a copy of this software insert the CD (Controller Support Tools) into your CD drive and install the software.
In the previous screen shot the RME 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. After clicking on the control of choice simply click the next button once again. The next screen appears below. as an input, output parameters do not apply and are therefore grayed out.
ting 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. Of course, there is an option to exit without saving a copy to the local hard drive. After selecting Save above click the "Finish" button once again. The screen below will than appear. When saving the configuration note the location where the file will be placed (Saved in) and enter the file name (File name) as well.
Function Block Descriptions Alarm Function Each of the next several pages graphically shows each of the RME function blocks. Note that as you view each you will find text that is black and text that appears gray. The gray text represents inputs that are not currently available based on the functions defined use (red text). For instance, when the defined use of the Alarm function is set to Off, all parameters will appear gray.
