Veeder Root Series C628 Position Indicator Technical Manual

Introduction

Your V eeder-Root brand C628 Position Indicator is one model in a family of 1/8 DIN units which offers breakthrough display technology as well as easy-to-program single-line parameters. Designed to provide instant visual feedback regarding an application’s key input value, the C628 not only has a 0.71” high LED display (27% larger than other 1/8 DIN units), but also the ability to change display color based on process status (programmable parameter in Operation Mode). Easy programming is made possible via a help function and a secondary legend display.

This manual will guide you through the installation and wiring of your C628 unit with information on proper panel mounting and rear terminal layout and wiring instructions. In addition, the instrument’s operation and programming modes are thoroughly explained. The Operation Mode provides day to day operation and allows editing of preset values. The Program Mode enables the configuration of various parameters prior to initial operation. These parameters include those for basic configuration as well as other settable features which will enhance the functionality and usability of the device.

This manual also provides information on the C628 Position Indicator’s alarms; transistor, relay and linear outputs; product specifications; and ordering and warranty procedures.

SIZE

The instrument can be mounted in a panel with a thickness of up to 6mm. The cutout(s) should be made based on the recommended panel opening illustrated in the drawing above.

Insert the unit in the panel through the cutout. Ensure that the panel gasket is not distorted and the instrument is positioned squarely against the panel. Slide the mounting clamp into place on the instrument, as shown to the left, and push it forward until it is firmly in contact with the rear face of the mounting panel and the tabs on the bracket arm are seated in the mounting grooves on the side of the unit.

The electronic components of the instrument can be removed from the housing after installation without disconnecting the wiring. To remove the components, grip the side edges of the panel and pull the instrument forward. Take note of orientation of the unit for subsequent replacement in the housing.

Input Power

For an AC powered unit, Terminal #13 serves as the line or Hot side connection for AC powered units and as the positive side for DC powered units. The neutral side for AC powered units and the negative side for DC powered units are connected to Terminal #14.

Count Inputs

Terminal #2 is the connection for Input A, which is used for channel A of an encoder input. Terminal #1 is the connection for Input B, which is used for channel B of an encoder input. The common connection for both Input A and Input B is Terminal #3.

Transistor Outputs

Your unit comes standard with 2 NPN outputs which are activated by each of the alarms. Transistor Output 1, which is tied to the High Alarm V alue, is on Terminal #7. Transistor Output 2, which is tied to the Low Alarm Value, is on Terminal #9. Terminal #8 serves as the common

Control/Digital Inputs

A contact closure or NPN signal can be used to activate preconfigured functionality. Terminal # 5 is used for a remote reset function, while Terminal #6 is a security function, that when active, will prohibit entry into Program Mode. Terminal #8 serves as the common for both of these inputs.

connection for both transistor outputs.

Relay Outputs

Your unit comes standard with a relay output which is tied to the High Alarm Value. Terminal #19 is NC, Terminal #20 is common, and Terminal #21 is NO. A second relay output tied to the Low Alarm V alue can be added as an option at the time of order or later installed in the

field. Terminal #22 is NC, Terminal #23 is common, and Terminal #24 is NO.

A 9 - 15 VDC for powering external sensors and encoders up to 125 mA can be accessed by connecting the positive supply side of the sensor to Terminal #4 and the negative side to Terminal #8.

Serial Communication

An RS-485 communication board, utilizing ASCII protocol, can be installed as an option. Terminals #16 & #17 serve as the B and A

signal relative to the Position Value. Terminal #12 is the positive side of the connection, and Terminal #10 is the negative side. The default range of the output is 4-20 mA, but can be changed via the front panel to 0-20 mA, 0-10 VDC, 2-10 VDC, 0-5 VDC, or 1-5 VDC.

Terminals 11 & 15 are not used.
