The Weschler BarGraph 2 Series High Reliability Digital BarGraphs are intended for use in applications where accurate and reliable measurement of a process value is of paramount importance. This series is designed to meet or exceed all national nuclear standards for environmental temperature and humidity extremes, seismic shock, EMI/RFI, HMI and system software V&V.

The BG2 is built for use in nuclear power plant (NPP) control rooms and other locations where physical and electrical environmental extremes may be found. The BV2-5A, BW2-1316 and BF2-6402 are housed in steel enclosures. The BG2-252 and BH2-252 use a high-impact, UV stabilized olycarbonate housing. Due to the self-shielded internal construction, no additional case shielding is required.

The BG2 Series features a five digit numeric display, that indicates to 99999 in the positive excursion and 19999 in the negative excursion. Character colors are blue, green, amber and red.

The 101 segment bar provides 1% resolution. A unique programming capability allows for fine control of set point annunciator visibility. In addition, the bar display can be configured to indicate with a single moving point, which simulates a pointer, or in standard expanded bar mode. It can also be configured in dual-slope or bipolar modes. The bar can be populated with LED’s in a single color (red, green, amber, blue), or in several different colors to provide a fixed banded mode of high color purity and brightness.

Up to four setpoint relays are available for control or alarms. These high current outputs can be programmed for either high or low action, with adjustable hysteresis, mode and delay. Red setpoint annunciators are provided when relays are specified. The trend indication option adds two red trend arrows to the front panel.

BG2-252 & BH2-252 meters are configured through the three front panel buttons. Front panel programming on the BW2-1316, BV2-5A and BF2-6400 is done with a plug-in programming module (EPM). For enhanced security, the front panel programming buttons can be disabled by configuring a setting requiring the installation of a jumper on the rear panel. When a communication option is ordered, the BG2 meters are also configurable through the RS-232, RS-485, Ethernet or USB port. Modbus and ASCII protocols are provided. With available setup software, configuration files can be created off-line and stored for uploading at a later time.

The Weschler ACP4 Power Series BarGraph is a self-contained instrument. No external current transformers, voltage transformers or phase shifters are required to measure up to 240V and 10A. However correct installation is critical. Consult the phaser diagrams to determine the proper configuration and phase orientation for the application, particularly in retrofit situations. Note that some three phase analog VAR meters may have been specified as a Wattmeter with a VAR scaleplate and 90 degree phase shifter. The ACP4 only supports an external phase shifter in 4-wire systems. For VAR measurements in 3-wire systems, the external phase shifter must be bypassed.

The Quatro BarGraph line is based on a precision 12000 count A/D converter and microprocessor control. Intelligent filtering smooths noisy signals while quickly responding to large signal changes. A wide selection of input modules easily interface to transducers, sensors and common process signals. Multi-range modules increase field configurability. Range selection is made by moving the on-board jumper.‍

Setpoints & Relays

‍Up to four setpoints can be configured for control and alarm functions. Setpoints are indicated on the bar display by a lit segment if the bar is below the setpoint and a dark segment if the display is above the setpoint. Up to 4 setpoints are available in each unit. Relays can be ordered to provide external control and alarms. Each relay may be configured to activate above its setpoint or below its setpoint. High current outputs handle SPST and SPDT switching up to 10A and 250VAC. Solid state relays (DC or AC/DC) are also available in the edgewise case. Setpoints 1 & 2 can be combined to define a hysteresis band for relay one. This is particularly useful in tank level applications. Depending on the relay mode selected, it will perform either a tank fill or tank empty function.‍

Bar Display‍

The 101 segment bar provides 1% resolution for the selected bar span, which can be any portion of the input range. Red, green and tricolor bars are available. The tricolor bar can be set to change color based on signal level. This provides an easily seen indication when a measured parameter needs attention. The setpoint values are the transition points for color changes. Any color can be set between two adjacent setpoint values. In a common application, the bar is green when the signal is below SP1. When the signal is between SP1 & SP2, the entire bar changes to orange. Above SP2, the entire bar changes to red.

‍Analog Retransmit‍

A 0-10V or 4-20mA isolated analog output is available for remote indication or SCADA interface. The output can be adjusted to track any portion of the input span. Rescaling of the bar will not affect the analog output. An internal jumper quickly changes between V & mA.

Initial setup on the Quatro meters is done through the front panel buttons. Once set, installation of a rear panel jumper disables this feature.

This high performance measurement and computation platform provides unique capabilities in a switchboard instrument. In addition to displaying and retransmitting a single channel signal, the Premo meter can display two channels, perform cross channel math, log data and control processes.

For processes with overshoot or undershoot, the PID mode on SP1 & SP2 provides stable control.‍

Datalogging

‍Premo BarGraph Meters will log data in either linear (writes until full) or cyclic (overwrites oldest data) FIFO modes. A reading can be triggered from the program button, a digital input, time or an alarm condition. Optional memory allows storage of up to 4000 readings in non-volatile EEPROM. The optional real time clock can be used to initiate readings and time stamp the data. A lithium battery provides clock back-up in the event of power loss. The clock will also activate a setpoint or control function at a preset time.

‍Display‍
