Installation and Removal

Figure 4 - 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 NEMA4X 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.

Input Wiring

Figure 8a – Thermocouple
Extension wire for thermocouples must be of the same alloy as the thermo­couple itself to limit errors.
Figure 8b – RTD (2- or 3-Wire) 100Platinum
There could be a +2°F input error for every 1of 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, multiple-stranded or solid, same metal.

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 13 ­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.
