Installation and Removal

Figure 3 - Series V4 multiple panel cutout dimensions.

NOTE: Measurements between panel cutouts are the minimum recommended.

Installing the Series V4 Controller

Installing and mounting requires access to the back panel.

1. Make the panel cutout using the panel cutout dimensions as shown in Figure 4.

2. Make sure the rounded side of the external case gasket is facing the panel surface.

3. Check to see that the gasket is not twisted, and is seated within the case bezel flush with the panel.

4. Slightly compress the top and bottom side of the V4 Case while pulling the controller into the panel cutout (Figure 5a). Slide the mounting collar over the back of the controller.The tabs on the collar must line up with the mounting ridges on the case for secure installation. The tab holes are facing the back of the controller.

5. Adjust the mounting bracket screws enough to allow for the mounting collar and panel thickness. Snap the upper and lower mounting brackets on the case of the controller (Figure 5 b). Make sure all the grips are well engaged on the mounting slots of the controller. (The four screw heads are facing the back of the controller.)

6. Make sure the case is seated properly.Tighten the installation screws firmly against the mounting collar to secure the unit (Figure 5c). To ensure NEMA 4X seal, there should be no space between the bezel and panel. Over tightening the screws will distort the case and make it difficult to remove or replace the controller.

NOTE: Be careful not to over-tighten the screws. This may cause the mounting cover to fail. Over-tightening occurs when the front bezel is touching the customer’s front panel.

Removing the Series V4 Controller

1. Loosen the upper and lower mounting bracket screws.

2. Use a flat screw driver to unsnap the four grips on the opposite side of upper and lower mounting brackets. Push the brackets back and forth gently until they can be pulled off easily.

3. Remove controller from the panel.

Sensor Installation Guidelines

We suggest you mount the sensor at a location in your process or system where it reads an average temperature. Put the sensor as near as possible to the material or space you want to control. Air flow past this sensor should be moderate. The sensor should be thermally insulated from the sensor mounting.

WARNING:

To avoid damage to property and equipment and/or injury or loss of life, use National Electric Code (NEC) standard wiring practices to install and operate this unit. Failure to do so could result in injury and/or death, or such damage.

NOTE:

Taking the unit out of the case is not a normal operating condition and should only be done by a qualified maintenance installation technician. Power to the case should be disconnected before removing or installing the controller into its case.

∫

WARNING:

The case terminals may still carry live voltage when the unit is removed.

∫

WARNING: Irreversible damage will occur if high voltage is applied to the low voltage unit.

Input Wiring

Figure 6a – Thermocouple

Extension wire for thermocouples must be of the same alloy as the thermocouple itself to limit errors.

Figure 6b – RTD (2- or 3-Wire) 100Ω Platinum

There could be a +2°F input error for every 1Ω of lead length resistance when using a 2-wire RTD. That resistance,when added to the RTD element resistance, will result in erroneous input to the instrument. To overcome this problem, use a 3-wire RTD sensor,which compensates for lead length resistance. When extension wire is used for a 3-wire RTD,all wires must have the same electrical resistance (i.e. same gauge, same length, multiplestranded or solid, same metal.

Figure 6c – Process,4-20mA Figure 6d – Process,0-5VÎ (dc)

Input impedance: 5Ω Input impedance: 10kΩ

NOTE:

Successful installation requires five steps:

• Choose the controller’s hardware configuration and model number;

• Choose a sensor;

• Install the con-

troller;

• Wire the controller and

• Configure the controller.

WARNING:

NOTE: When an external device with a non-isolated circuit common is connected to the 4-20mA or dc output, you must use an isolated or ungrounded thermocouple.

CAUTION: Process input does not have sensor break protection. Outputs can remain full on.

Setting up the Series V4 is a simple process. First set the DIP switches to match your input type. Refer to the orientation on the back of the controller to select the [``In] Input value. Next, configure the Series V4's features to your application in the Setup Menu, then enter values in the Operating Menu. Both tasks use the ‰Advance key to move through the menus and the Up-arrow/Down-arrow keys to select data.

Before entering information in the Setup Menu, set the [`dFL] parameter. If [``SI] is selected, °C, proportional band in % of span, derivative and integral are the defaults.If [``US] is selected,°F,proportional band in degrees,reset and rate are the defaults. Changing the [`dFL] prompt will set parameters to their factory default. Document all current parameter settings first. See the calibration section in the Appendix to change this parameter.

Entering the Setup Menu

The Operation Menu will appear as the default menu of the Series V4.The Setup Menu displays the parameters that configure the Series V4's features to your application.

Enter the Setup Menu by pressing the ¿Up-arrow and ¯Down-arrow keys simultaneously for 3 seconds.The lower display shows the [`LOC] Lock parameter, and the upper display shows its current level. All keys are inactive until you release both keys.You can reach the Lock parameter from anywhere.

Use the ‰Advance key to move through the menus and the ¿Up-arrow and ¯Down-arrow keys to select data. You will not see all parameters in this menu, depending on the controller's configuration and model number. After stepping through the menu it returns to the set point parameter under the Operation Menu. If no keys are pressed for approximately 60 seconds, the controller returns to the default display, Process over Set Point.

Calibration

Before attempting to calibrate, make sure you read through the procedures carefully and have the proper equipment called for in each procedure. Make sure the DIP switches are in the proper position for the input type.

Entering the Calibration Menu

In the Calibration Menu, various input signals must be supplied for the controller to go through its auto calibration. The Calibration Menu can only be entered from the [`LOC] Lock parameter in the Setup Menu. Press the ¿Up- arrow/¯Down-arrow keys simultaneously for 3 seconds (± 1 second). The [`CAL] parameter appears in the lower display with "no" in the upper display.

Any inadvertent change in the displayed data, when pressing the ¿Up- arrow/¯Down-arrow keys, is ignored. Calibration values won't be retained unless you are in the manual mode. Press the ¿Up-arrow or ¯Down-arrow key to change the upper display to [`YES] Press ‰Advance to enter the calibration sequence.

Upon entering the calibration menu, the upper display window indicates [`CAL]. It continues to indicate [`CAL] (with the exception of calibration of the 4-20mA output) while the operator walks through the entire calibration parameter list. While calibrating the 4-20mA output, the upper display contains a numeric value to be slewed up or down until the output value is correct. The controller uses the lower display to prompt the user as to what the input should be.

With the [`dFL] parameter,select either [``US] parameters which include displaying °F, rate, reset, and proportional band in degrees or units. Or select [``SI] (System International) and the displayed parameters are °C, integral, derivative, and proportional band in % of span.

Once the information has been properly established and maintained for at least 5 to 10 seconds, the ‰Advance key may then be used to display the next prompt. After the final input is established, press the ‰Advance key twice to return the controller to the configuration menu at the top of the parameter list.

Figure 19 Entering the Calibration Menu.

NOTE:

While in the Calibration Menu, the controller output(s) go off and the alarm output (if present) is on.

NOTE: Calibration values will not be retained unless you are in the MANUAL mode. Do not enter the MANUAL mode until you are at the correct input parameters.
