Omron E5ZN Manual 

• The E5ZN is a Temperature Controller that features the ability to be built into equipment. • The E5ZN is equipped with RS-485 communications, so process values can be monitored and parameters can be read or written from the host system. • The Terminal Unit can be separated from the Controller, so maintenance can be performed on the Controller without changing the wiring. • If two or more Controllers are connected to the same host system, use an expansion Terminal Unit and close mounting to safe space and reduce wiring. Using Setting Switches Controller Front panel Terminal Unit Standard Model Expansion Model Baud Rate Operation Indicators Unit Number Switch Set the baud rate of the Controller to match the baud rate of the host system. • POWER Lights when power is turned ON. • ERROR Lights when an input error (e.g., memory error or input error for any channel) occurs. • SD/RD (Send Data/Receive Data) Light during communications with the host. • OUT1, OUT2 (Control Output 1, Control Output 2) Light when the control output 1 or the control output 2 functions are ON. • SUB1, SUB2 (Auxiliary Output 1, Auxiliary Output 2) Light when the auxiliary output 1 or the auxiliary output 2 functions are ON. Front Panel Set the unit number to identify the Controller connected to the host system and to the Setting Display Unit (E5ZN-SDL). The unit number is hexadecimal. Switch settings 0 to F correspond to unit numbers 00 to 15. Set a different unit number for each E5ZN if more than one is connected using RS-485 communications. Communications cannot be performed if the same unit number is used more than once on the same line.

This function can be used only when control is stopped. When copying settings, first finish making settings for the Temperature Controller in the normal mode, then upload and download in Copy Mode. Upload (Temperature Controller to Setting Display Unit) Step 1 Press the COPY Key for at least 1 s to enter Copy Mode. Step 2 Use the UP and DOWN Keys to select up on Display No. 2. Press the UNIT Key to select the unit number for the upload. Any unit number from 0 to f or "-" (all units) can be selected. Step 3 Press the LEVEL Key for at least 1 s to start the upload. Note: 1. up will flash on Display No. 2 during the upload. 2. The mode will return automatically to the Operation Level when the upload has been completed. Download (Setting Display Unit to Temperature Controller) Step 1 Press the COPY Key for at least 1 s to enter the copy mode. Step 2 Use the UP and DOWN Keys to select down. The possible selections are up and down. Step 3 Press the UNIT Key to select the unit number for which data has been uploaded. Any unit number from 0 to f can be selected (for each Unit). The unit number for any Controllers without uploaded data, however, will not be displayed. Also, selection will not be possible if the uploaded information in the display was uploaded from all Controllers. The UNIT display will be "-". Note: For example, to download setting data from unit number 1 to unit number 2, change the unit number from 2 to 1, and change the number of unit number 1 to another unit number or disconnect the socket connected to unit number 1. Be sure that there is only one Controller with the same unit number on the network at any one time. Step 4 Press the LEVEL Key for at least 1 s to start the download. Note: 1. down will flash on Display No. 2 during the download. 2. The mode will return automatically to the Operation Level when the download has been completed. Supplementary Explanation To download to all Temperature Controllers, use the same configuration as when the data was uploaded. Downloading is not possible in the following circumstances. If downloading is not possible, down will flash and then the upload display will be shown. • An E5ZN has been added or deleted since the upload. • The same number of Controllers are connected as when the upload was executed, but when the unit numbers are different. • The resistance thermometer/thermocouple type configuration is different. Copying Parameters from an E5ZN Master to Other E5ZNs This section describes how to copy parameters from Unit 1, used as the master, to Units 2 and 3, as shown in the following diagram. Data uploaded to the E5ZN-SDL can be downloaded only to a Controller whose unit number has been uploaded. Therefore, after copying the Master parameters, change the unit number of the Controller where the data is to be downloaded to the unit number from which data was uploaded (i.e., the master's unit number), and then download the parameter data. Step 1 Select Copy Mode. Press the COPY Key for at least 1 s to enter Copy Mode. Step 2 Press the UNIT Key to select the unit number of the master. In this example, the master is unit number 1, so select 1. Step 3 Upload all the parameters from the Master. In this example, all the parameters from unit number 1 will be uploaded to the E5ZN-SDL. Press the LEVEL Key for at least one second to start the upload. up will flash on the display during the upload. The mode will return automatically to Run Mode when the upload has been completed. copy up 0 copy down 0 23 0 0 E5ZN-SDL System Configuration Master E5ZN 1 E5ZN 2 E5ZN 3 23 0 0 copy up 1 copy up 1

downloaded to the unit number of the Controller from which the data was uploaded. When uploading has been completed, turn OFF the power and disconnect the uploaded Controller (unit number 1) from the socket or change the unit number to avoid using the same unit number twice during the download. In this example, change the unit number of the master from 1 to 5, and change the unit number of the Controller to which the data is to be downloaded from number 2 to number 1. The system configuration will change to the configuration shown in the following diagram. Step 5 Select Copy Mode. Turn ON the power and press the COPY Key for at least 1 s to enter the Copy Mode. Step 6 Set the download mode and the copy destination. Use the DOWN Key to select down on Display No. 2. Press the UNIT Key to select unit number 1. (The lowest unit number that is being uploaded will be displayed in the download unit number display. At initialization, there is no upload data, so the unit number display is blank.) Step 7 Press the UNIT Key for at least 1 s to start the download. down will flash on the display during the download. The mode will return automatically to Run Mode when the download has been completed. Step 8 Copying to Other Controllers Repeat steps 4 to 7 to continue copying the data. The following example shows copying data to unit number 3. Turn OFF the power and change unit number 1 back to unit number 2. Change unit number 3, where the data is to be downloaded, to unit number 1. The system configuration is shown in the following diagram. Turn ON the power and follow steps 4 to 7 to copy data to unit number 3. Step 9 Changing back to the original unit number. After copying has been completed, turn OFF the power and change back to the original the unit numbers. In this example, turn OFF the power and change unit number 5 to unit number 1, and change unit number 1 to unit number 3. 23 0 0 Master Copy destination E5ZN 5 E5ZN 1 E5ZN 3 copy up 0 copy down 1 copy down 1 23 0 0 Master Copy source Copy destination E5ZN 5 E5ZN 2 E5ZN 1

Parameters are divided into groups called levels. Each of the items that is set in any of the levels is called a parameter. The parameters on the E5ZN are divided into the following seven levels: ❍: Indicates items that can be set. Note: To move to the Advanced Function Setting Level, set the Initial Setting/Communications Protection parameter in the Protect Level to 0. Of these levels in normal mode, the Initial Setting Level, Communications Setting Level, and Advanced Function Setting Level can be used only when operation is stopped. Operation stops when any of these four levels are selected. It is possible to enter Copy Mode while control is being performed, but copy operations (e.g., upload and download) can be used only when control has stopped.

Protect Level • To enter the Protect Level, simultaneously press the and M Keys for at least 3 s in the Operation Level or Adjustment Level. The Protect Level is for preventing unwanted or accidental modification of parameters. Protected levels will not be displayed, and so the parameters in that level cannot be modified. Operation Level • This level is displayed first when you turn ON the power to the E5ZN. You can move to the Protect Level, Initial Setting Level, or Adjustment Level from this level. • During operation, the PV, SP, and MV can be monitored, and the SP, alarm value, upper limit alarm and lower limit alarm can be monitored and modified. Adjustment Level • To enter the Adjustment Level, press the Key for less than 1 s. • This level is for entering set values and offset values for control. The level contains parameters for setting the auto-tuning, communications writing ON/OFF, hysteresis, multi-SP, input correction values, heater burnout alarm (HBA) settings, PID constants, etc. You can move to the top parameter of the Initial Setting Level and Operation Level from here. Initial Setting Level • To enter the Initial Setting Level, press the Key for at least 3 s in the Operation Level or Adjustment Level. The first display flashes after 1 s. The Initial Setting Level is for specifying the input type, selecting the control method, setting the control period, setting direct/reverse operation, and selecting the alarm type. You can move to the Advanced Function Setting Level or Communications Setting Level from this level. To return to the Operation Level, press the Key for at least 1 s. To move to the Communications Setup Level, press the Key for less than 1 s. (The display will be blank ("----") when you move from the Initial Setting Level to the Operation Level.) Advanced Function Setting Level • To enter the Advanced Function Setting Level, you must enter 0 for the Initial Setting/Communications Protection parameter in Protect Level, and then enter the password (−169) in the Initial Setting Level. • You can move only to the Initial Setting Level from the Advanced Function Setting Level. • The Advanced Function Setting Level sets the MV limits, event input assignments, standby sequences, alarm hysteresis, and other parameters. Communications Setting Level • To enter the Communications Setting Level, press the Key for less than 1 s in the Initial Setting Level. When the communications settings are to be used, set the communications conditions in this level. Communications with a host device (e.g., computer) enables SPs to be read and written, and MVs to be monitored.

Use the error message to check the type of error and correct the error accordingly. PV display Error Meaning Action Operation Input error The input value has exceeded the control range∗. ∗Control Range Resistance thermometer or thermocouple input: SP lower limit −20°C to SP upper limit 20°C (SP lower limit −40°F to SP upper limit 40°F) ES1A input: Same as input indication range Analog input: −5% to 105% of scaling range Check the wiring of inputs for mistakes in wiring, disconnections, short-circuits, and the input type. If no abnormality is found in the wiring and input type, turn the power OFF then back ON again. If the display remains the same, the E5ZN must be repaired. If the display is restored, then electrical noise may be affecting the control system. Check for electrical noise. After the error occurs, the error is displayed, and control outputs turn OFF. Alarm outputs operate as if the upper limit has been exceeded. This error message is displayed when the PV or PV/ SP is displayed. Display Range Over This message does not indicate an error. It is displayed if the PV exceeds the display range and the control range is larger than the display range (−1999 (−199.9) to 9999 (999.9)). • Less than -1999 (−199.9): • More than 9999 (999.9): --- Control continues and operation is normal. This message is displayed when the PV or PV/SP is displayed. Memory Error There is an error in the internal memory operation for the E5ZN-SDL Setting Display Unit. First, turn the power OFF then back ON again. If the display remains the same, the E5ZN must be replaced. If the display is restored, then electrical noise may be affecting the control system. Check for electrical noise. Key operations are not possible. Current Value Exceeded This error is displayed when the heater current value exceeds 55.0 A. --- Control continues and operation is normal. This error message is displayed when the heater current value monitor is displayed. Disabled Status This error is displayed when one of the following errors has occurred in the connection with the E5ZN. • The connecting cable is disconnected. • The power supply to the E5ZN-SDL has been turned OFF while in Copy Mode. • A memory error has occurred in the E5ZN. The control output and alarm outputs will be OFF for the E5ZN generating the error. --- Controllers that do not show this disabled status will continue operation and will operate normally. The selected Controller and the channel status will be displayed. In the interest of product improvement, specifications are subject to change without notice. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
