3. PRODUCT INTRODUCTION

Our digital panel meters are versatile, cost effective solutions to a wide variety of monitoring and control applications. Depending on the choice of signal conditioner, they are easily set up for an accurate display of temperature, pressure, flow, weight, voltage or current, all in appropriate engineering units and with zero and span adjustment when needed. Setup can be via front panel pushbuttons or the meter’s serial interface. Selective security lockout of the front panel keys protects against accidental changes to meter setup.

High read rates up to 60 per second (50 for 50 Hz operation) are made possible by Concurrent Slope Conversion (Pat 5,262,780), which integrates the signal over an AC power line cycle for maximum noise rejection. High read rates provide accurate peak and valley capture, and quick response for control applications. An adaptive digital filter supplies a time constant for the encountered signal noise level, yet responds rapidly to changes that exceed a selected threshold. Self-calibration occurs automatically after every 17th reading.

The standard power supply is a high-efficiency switching unit that operates from AC or DC, and allows the meters to be powered from worldwide AC without changes. A low-voltage supply is optional for power from 10-48V batteries or from 12-30 Vac. Both supplies provide an isolated 5, 10 or 24Vdc transducer excitation output.

The meter case conforms to the 1/8 DIN size standard. It is made of high impact, 94V-0 ULrated plastic and is watertight to NEMA-4 (IP65) when panel mounted. Mounting is from the front of the panel and requires less than 110 mm behind the panel. Power and signal wiring is via removable plugs conforming to UL61010C safety standards. All output options are isolated from meter and power ground to 250 Vac.

Extended meter versions can linearize nonlinear inputs. Up to 180 data points may be linearized by a computer program that stores setup parameters in nonvolatile memory. Extended meters can also display rate of change, for example to display flow rate based on changing tank level.

Alarm or setpoint control is provided by an optional relay board with two or four Form C 8A mechanical relays or two or four Form A 120 mA solid state relays. The setpoints may be latching or non-latching, be energized above or below the setpoint, or operate in a fail-safe mode. The relays can operate from the filtered signal to reduce relay chatter or from the unfiltered signal for fastest response. Snubber circuits and a programmable relay switching time delay extend relay contact life.

An isolated analog output of 4-20 mA, 0-20 mA, 0-10V or -10 to +10V can be provided by an optional analog output board. The output is linearized to the display and can operate from the filtered or unfiltered signal input. It can be scaled via front panel pushbuttons or the meter’s serial interface.

Ethernet USB, RS232, or RS485 (2-wire half-duplex or 4-wire full-duplex) serial communications options are available with the Modbus protocol or a simpler custom ASCII protocol. Modbus operation includes RTU or ASCII modes, up to 247 digital addresses, and up to 32 devices per RS485 line without a repeater. Ethernet-to-RS485 and USB-to-RS485 converter boards allow a meter to be interfaced to a PC and to multiple meters on an RS485 network.

Meter programming can be via the meter’s front panel or a PC running Windows based Instrument Setup Software (serial interface option required).

REMOVING THE ELECTRONICS

With the rear panel removed, grasp the power supply board to the left and signal conditioner board to the right, and carefully slide the electronic assembly out through the rear of the case. (see figure below).

INSTALLING NEW 0PTION BOARDS

Options boards plug into the main board at the front of the meter. These are plug-and-play and may be installed in the field. They will be recognized by the software, which will provide access to the menu items associated with that board. If necessary, remove rear panel knockouts for new boards. Boards plug into connectors as follows:

Option Board	Main Board Plug	Rear Panel Jack
Power supply	P11	J1
Relay board	P12	J2
Serial interface board	P13	J3
Analog output board	P14	J4
Signal conditioner board	P15	J5
	8

Note: Corresponding main board and option board connectors have the same number of electrical lines. When an option board is correctly installed, the top and bottom edges of the main board and option board are aligned.

REASSEMBLING YOUR METER

Slide the electronics assembly into the case until the display board is seated flush against the front overlay. Insert the bottom tabs of the rear panel into the case, and then carefully align the board connectors with the openings in the rear panel. If necessary, remove any rear panel knockouts for new option boards that may have been installed. Ensure that all option boards are properly aligned with the molded board retaining pins on the inside of the rear panel. Once the rear panel is in place, reinstall the input/output screw clamp terminal plugs.

PANEL MOUNTING

Ensure that the panel mounted gasket is in place against the back of the bezel. Turn the two mounting screws counterclockwise until the space between the mounting pawl and the rear of the gasket is greater than the panel thickness. Insert the meter in the panel cutout. Turn the mounting screws clockwise until the meter is securely mounted in the panel. Do not overtighten.

8. FRONT PANEL SETUP KEYS

Meter Front Panel

There are four front panel keys, which change function for the Run Mode and Menu Mode, effectively becoming eight keys. The keys are labeled with alphanumeric captions (MENU, PEAK, RESET, ALARMS) for the Run Mode and with symbols ( right arrow, right triangle, up triangle, left arrow) for the Menu Mode.

FRONT PANEL LOCKOUT

The Menu Mode will not work with most meters as received from the factory, since all menu items have been disabled in software and a lockout jumper is in place. That jumper needs to be removed for the Menu Mode to work, and menu items under Loc 1, Loc 2 and Loc 3 then need to be set to "0" via the front panel for these menu items to be unlocked See Section 9. The paragraphs below assume that all menu items have been unlocked.

MENU MODE KEY ACTION

In the Menu Mode, pressing a key momentarily advances to the next menu item. Holding down a key automatically advances through multiple menu items for fast menu navigation.

KEYS IN RUN MODE

MENU Key. Pressing MENU from the Run Mode enters the Menu Mode. Pressing MENU repeatedly will step the meter through the various menu items (if these have not been locked out) and then back to the Run Mode.

PEAK Key. Pressing PEAK normally causes the peak value of the input signal to be displayed. The peak display then blinks to differentiate it from the normal present value display. Pressing PEAK again returns the display to the present value. The PEAK key can also be programmed to display Valley, alternating Peak or Valley, or to Tare the reading to zero. When Peak or Valley is selected, periodic horizontals bars at the top of the display indicate Peak, and periodic horizontals bars at the bottom indicate Valley.

RESET Key. Pressing RESET with PEAK resets peak and valley values. Pressing RESET with ALARMS resets latched alarms. Pressing RESET with MENU performs a meter reset (same as power on). Meter reset can also be applied via a rear panel connect or a serial ASCII command.

ALARMS Key. Pressing ALARMS once displays the setpoint for Alarm 1. Pressing it again displays the setpoint for Alarm 2. Pressing it again returns to the present value.

10

KEYS IN MENU MODE

Right Arrow Key (MENU). Pressing steps the meter through all menu items that have been enabled and then back to the Run Mode. With the DC signal conditioner board and no option boards, available menu items are _InPut, SEtuP, ConFG, _FiLtr, dEc.Pt, SCALE, OFFst, Loc 1, Loc 2, Loc 3. If a change has been made to a menu item, that change is saved to non-volatile memory when the key is pressed next, and StoreE is displayed briefly.

Right Triangle Key (Digit Select).

•Pressing from the InPut menu brings up all meter functions available with the meter's signal conditioner. For the DC signal conditioner, these are _dC U, _dC A and _rAtio.

•Pressing from the SEtuP, ConfFG, FiLtr, SCALE, OFFSt, Loc 1, Loc 2 or Loc 3 menus items sequentially selects digit positions 1 - 5, as indicated by a flashing digit: 00000, 00000, 00000, 00000, 00000.

•Pressing from the dEC.Pt menu item sequentially selects decimal point positions, which will flash: d.dddd dd.ddd ddd.dd dddd.d ddddd. .ddddd.

Up Triangle Key (Value Select). Pressing for a flashing item (digit position or decimal point position) will increment that item. Pressing MENU will save any changes.

Left Arrow Key (Reverse Menu). Pressing has the same effect as the MENU key, except that menu items are brought up in reverse order.

11

9. ENABLING & LOCKING OUT MENU ITEMS

For security reasons and ease of meter operation, any and all menu items may be disabled or "locked out" so that they are no longer directly accessible from the front panel. Each function to be disabled is set to "1" in menu items Loc 1, Loc 2 or Loc 3, and each function to be enabled is set to "0." The top menu items Loc 1, Loc 2 and Loc 3 can in turn be locked out by installing an internal hardware jumper. With the jumper installed, the operator only has access only to enabled menu items. With the jumper removed, the operator also has access to menu items Loc 1, Loc 2 and Loc 3.

SETTING HARDWARE LOCKOUT JUMPER

To access the lockout jumper, remove the rear panel per Section 9 and locate jumper “a” in the lower portion of the power supply board next to the input connectors (see figure at right).

SETTING SOFTWARE LOCKOUTS

When setting up the meter, it may be necessary to enable specific menu items by setting the corresponding lockout digit to 0. Be sure to reset the lockout digit to "1" if you do not want the menu item to be changed by an operator.

Loc 1 Loc 2 Loc 3

Press the MENU key until Loc 1, Loc 2 or Loc 3 is displayed, as desired. Note: the hardware lockout jumper must be removed (see above).

11111

Press to display the lockout status, consisting of 1’s and 0’s. The left digit will flash. Press again to step to the next digit, which will flash.

10. READING COORDINATES OF 2 POINTS SCALING METHOD

When the reading coordinates of 2 points scaling method has been selected under SEtuP, the four menu items below will appear ahead of all other menu items when the MENU or key is first pressed from the run mode.

This scaling method applies a straight line fit between two points, which are determined from actual transducer signals and the desired corresponding meter readings. A low signal, such as the output of a pressure transducer at zero pressure, and high signal, such as the output of the same transducer at a known high pressure, are applied to the meter. The desired corresponding low and high readings are then entered from the front panel. The meter then applies straight line fit between the high and low calibration points. This scaling method has the advantage of calibrating the transducer and meter as a system. The actual voltage or current at either point does not need to be known. This method is ideal for process and load cell meters, which require zero and span adjustment. It is also available for DC or AC meters. It is not available with thermocouple or RTD meters.

The programming example below is for a process meter used with a 4-20 mA pressure transducer for 0 to 100 psi. Decimal points are set separately using the dEC.Pt menu.

11. DC VOLTS, AMPS, PROCESS, STRAIN INPUT

The DC Volts, Amps, Process and Strain meters utilize the DC signal conditioner board, which needs to be configured via jumpers for the desired voltage or current range. All signal ranges are factory calibrated with calibration factors stored in EEPROM. The meter software recognizes the board and will bring up the appropriate menu items for it; however, it does not recognize the jumper settings. Please see further manual sections for setup of the following: relay output (16), analog output (17), communications (18), and excitation output (19).

4.Store spare jumpers on an unused jumper post not associated a capital letter.

SCALE & OFFSET SETUP

For DC voltmeters & ammeters, a scale factor of 1 and an offset of 0 are used for direct readings in (milli)volts or (milli)amperes. Decimal point selection does not affect the displayed digits. For example, 0-20V or 0-20 mA signals can both be displayed as 0-20000. A full scale of 20000 may be displayed as 20.000 mA or 20000 SA. Use with a current shunt will require a scale factor to be set. For example, for a 500-100 (500A, 100 mV) shunt, divide 5000 (the desired full scale display with 0.1A resolution) by 10000 (displayed value with 100 mV when the scale factor is 1.0) for a scale factor of 0.5.

For process & strain meters, scaling is normally set up from the front panel using the and keys, but can also be set up via RS232/485 using special PC-compatible setup software (available at no charge). The meter allows three scaling methods to be selected: 1) Scale and offset, 2) Coordinates of 2 points, and 3) Reading coordinates of 2 points. Only menu items applicable to the selected method will be presented.

12. LOAD CELL & MICROVOLT INPUT

The Load Cell and Microvolt meters utilize the load cell signal conditioner board, which offers sensitivity to ±20 mV full scale and 4 or 6-wire load cell connection. This board needs to be configured via jumpers for the desired voltage range. All signal ranges are factory calibrated with calibration factors stored in EEPROM. The meter software recognizes the board and will bring up the appropriate menu items for it; however, it does not recognize the jumper settings. Please see further manual sections for setup of the following features: relay output (16), analog output (17), communications (18), and transducer excitation output (19).

±250 mV			c	±25000
±500 mV			d	±50000
Notes	1.		See Section 19 to select 10V excitation.
	2.		Jumpers are 2.5 mm (0.1 in).

SCALE & OFFSET SETUP

For DC microvolt meters, a scale factor of 1 and an offset of 0 are used for direct readings in microvolts or millivolts. Decimal point selection does not affect the displayed digits. For example, 20 mV can be displayed as 20.000 mV or 20000 SV. The decimal point is set separately.

For load cell applications, scaling is normally set up from the front panel using the and keys, but can also be set up via RS232/485 using special PC-compatible setup software (available at no charge). The meter allows three scaling methods to be selected: 1). Manual scale and offset, 2) Coordinates of 2 points, and 3) Reading coordinates of 2 points. Please see the Glossary for an explanation of each method.
