WARNING!
This instrument contains electronic components that are susceptible to damage by static electricity. Proper handling* procedures must be observed during the removal, installation, or handling of internal circuit boards or devices.
*Handling Procedure
1. Power to unit must be removed.
2. Personnel must be grounded, via wrist strap or other safe, suitable means, before any printed circuit board or other internal device is installed, removed or adjusted.
3. Printed circuit boards must be transported in a conductive bag or other conductive container. Boards must not be removed from protective enclosure until the immediate time of installation. Removed boards must be placed immediately in protective container for transport, storage, or return to factory.
Comments This instrument is not unique in its content of ESD (electrostatic discharge) sensitive
components. Most modern electronic designs contain components that utilize metal oxide technology (NMOS, CMOS, etc.). Experience has proven that even small amounts of static electricity can damage or destroy these devices. Damaged components, even though they appear to function properly, may exhibit early failure.

DESCRIPTION & SPECIFICATIONS
Description:
Featuring 6 digits of bright, 7-segment LED displays, this unit is an integrating totalizer/ratemeter which ac­cepts analog signal inputs. The unit can be field programmed to accept 0-20mA, 4-20mA, 0-5V, 0­10V or 1-5V signals. An optional Square Law input is available for inputs that require square root extrac­tion. A 4-20mA output option is available to control strip recorders or other peripherals. Two assignable set points are standard for two stage shut off. The high and low scaling settings are programmable from the front panel. By pressing the "view" button, the unit will display: integrated total, rate, peak or valley. RS-422 or RS-232 serial communications are avail­able options for data communication with a host com­puter.
Specifications: Display: 6 digit, .55" high, LED. Input Power: 110, 220 VAC ± 15% or 12 to 24VDC.
Current: maximum 300 mA DC or 10.0 VA at rated AC voltage. Output Power: (AC powered units only) + 24VDC. @ 50 mA regulated ±5%
Temperature:
Operating: +41°F (5°C) to +130°F (+54°C). Storage: -40°F (-40°C) to +200°F (93°C). Memory: EEPROM stores data for ten years if power is lost. Reset: Front Panel: resets displayed values and control out­puts. Remote: 4-30 VDC positive edge, resets totalizer and control outputs. Control Outputs: Standard: Open collector sinks 250 mA from 30VDC when active. Optional: 2 each Form C SPDT 10Amp @ 120/240 VAC or 28 VDC. (Open collector outputs are also supplied with 10VDC provided at transistor outputs through relay coil. If greater than 2mA is used, relay will remain energized. Applying greater than 10 VDC may destroy unit. Transistor will sink 100mA in "ON" state.)
Input:
Standard: Linear 0-20mA, 4-20mA, 0-5V, 0-10V or 1­5V selectable from the front panel. Optional: Square Law 0-20mA, 4-20mA, 0-5V, 0-10V, or 1-5V, is available for inputs that require square root extraction.
Input Impedance: Current: 100; Voltage: 115K Calibration: The unit does all of the calibrations inter-
nally. There are no potentiometers to adjust and the unit never needs to be removed from the case.
Set Points: The two control set points can be set at any number from 0 to 59999. The set point outputs can be assigned to rate or total. The unit comes standard with two open collector control outputs. Two 5 Amp, Form C relays are optional. The outputs are programmable from .01 to 599.99 sec or latched until reset when assigned to the total and a hysteresis (alarm range) when assigned to the rate. Rate Display: Updates 5 times per second, Accurate to
4.5 digits. Set "low" greater than "high" for inverted display (LINEAR ONLY). Totalizer: Integrates from the rate reading and accu­mulates up to 6 digits of total count. The time base (hours, minutes or seconds) is field programmable from the front panel. Analog Out: The unit can be ordered with an optional 4-20mA output which is proportional to the rate display. The high and low settings are programmable from the front panel. Set "low" greater than "high" for inverted output. A sinking driver generates a corresponding linear current through the external devices. The output updates with each update of the rate. Accuracy is 50uA worst case. For rated accuracy, load must be con­nected to the analog output before unit is powered. Compliance voltage must be 3 to 30 VDC non inductive. (The unit can provide the DC source as long as the drop across the devices being driven does not exceed 21V). Programming: Decimal points, Scaling from 0 to 59999 units per selected time base, set points, input type, security lock code, and assigning outputs are all programmable from the front panel. Housing: Standard 1/8 DIN, high impact 94VO plastic case.

HOW TO MOUNT:
MOUNTING
Slide the body of the unit through the rubber gasket. Insert the unit into the panel. Slide the brackets up the groove to press against the back of the panel, as shown in "FIG. A". Insert the screws into the rear of the brackets.

Tighten the screws evenly and alternately. A panel less than .1" may distort if the clamps are screwed too tightly. Do not over tighten! A normal level of torque is required. Maximum torque should be 3" pounds. The panel must be parallel to the bezel to assure proper seal. Unit seals to NEMA 4/ IP65 if properly mounted.

WIRING
AC / DC CONNECTIONS: NOTE: Connect power only after other connec­tions are finished. Do not touch the live AC power terminals. The unit has been designed with an isolated AC input, therefore polarity is not a con­cern for the AC power. The chassis is plastic, therefore earth ground is not used. For DC opera­tion, connect +DC to terminal 10 and -DC to terminal 3.
This Product complies with requirements of the European Community Directive 89/336/EEC [Elec­tromagnetic Compatibility]. However, electrical noise or intense electromagnetic fields in the vicin­ity of the unit may disturb the microprocessor. Users should exercise care and should take proper precautions to avoid microprocessor disturbance.
Four common sources of noise are:
1) AC power line noise- The input power lines should not be common to power lines for motors, pumps, contactors, etc. If the unit cannot be con­nected to an electrically clean power source, an inductive load suppressing device (MOV as GE#V130LA1 or Resistor Capacitor as Paktron# .2uf/220 ohm @ 400V) can be installed. Although locating the suppressor across the AC supply at the unit should help, best results are obtained by connecting the suppressor across the leads of the "load" at the device causing the spikes.
2) Input line noise- The noise is carried on the input and DC ground lines. Make sure the input wires are not run into the unit in a bundle with power input lines. We recommend using shielded cable. Con­nect the shield to DC ground of the unit and "earth" at one point in the circuit preferably at the DC ground terminal of the unit.
3) Output lines- The unit has two open collector outputs and two optional relay outputs. When these outputs are used to run external relays or solenoids, spikes can be generated upon activa­tion. This noise can spread through the instrument causing operating problems. If the source is a D.C. operated device, a general purpose diode (IN4004) placed across the solenoid prevents electrical noise spikes. Connect the cathode (banded side) to the more positive side of the coil. If the source is an A.C. operated device, use a Resistor Capaci­tor or MOV across the coil.
4) 24 VDC output supply- Noise can be generated on the 24 VDC output supply if it is used to drive inductive loads or if the current draw exceeds 50mA. Insure that all inductive loads have a diode (such as IN4004) across the coil and that the current does not exceed 50mA.
