Overview The V4 1/4 DIN panel mount controller is a general purpose industrial PID temperature controller. The V4 provides a reliable cost-effective solution for most temperature control applications. Thermocouple, RTD, and Current and Voltage sensors are supported. Dual outputs can be configured to support heating and cooling. The secondary output can also be configured as an alarm.
Keys and Displays Upper Display: Indicates the process value, actual temperature, operating parameter values or an open sensor. When powering up, the Process display will be blank for five seconds. • To set to blank, set [`dsP] to [`SEt] in the Setup Menu. Lower Display: Indicates set point, output value, parameters for data in the upper display, or error and alarm codes. • To set to blank, set [`dsP] to [`Pro] in the Setup Menu.

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.
Installation and Removal (continued) Figure 5a - Slightly compress the case while pulling the controller into the panel cutout. Figure 5b - Snap the top and bottom mounting bracket into the slots. Figure 5c - Tighten screw to secure the controller. Figure 5d - Remove the controller using a flat screwdriver. 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.
ç 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: Input Wiring Successful installation requires five steps: Figure 8a – Thermocouple • Choose the controller’s hardware configuration and model number; Extension wire for thermocouples must be of the same alloy as the thermocouple itself to limit errors. DIP Switch Orientation 1: OFF 2: ON • Choose a sensor; • Configure the controller.

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.
Calibration Menu Figure 14 Calibration Parameters. Thermocouple Field Calibration Procedure Equipment Required • Type "J" Reference Compensator with reference junction at 32°F/0°C, or Type "J" Thermocouple Calibrator set at 32°F/0°C. • Precision millivolt source, 0-50mV min. range, 0.01mV resolution NOTE: Before calibration on an installed controller, make sure all data and parameters are documented. Setup And Calibration 1. Connect the ac line voltage L1 and L2 to the proper terminals. 2.
RTD Field Calibration Procedure Equipment Required • 1KΩ precision decade resistance box with 0.01Ω resolution. NOTE: When the % indicator light is on, the controller is automatically calibrating. Your sequence is VERY important. Always move to the next parameter before changing the calibration equipment. Setup And Calibration 1. Connect the ac line voltage L1 and L2 to the proper terminals. 2. Connect the decade resistance box to Terminal 4, 5 and 6 on the terminal block.
4-20mA Input Field Calibration Procedure Equipment Required: • Precision current source 0-20mA minimum range with 0.01mA resolution. Setup and Calibration NOTE: When the % indicator light is on, the controller is automatically calibrating. Your sequence is VERY important. Always move to the next parameter before changing the calibration equipment. 1. Connect the ac line voltage L1 and L2 to the proper terminals on the V4. 2.
