Wiring and Hookup Diagrams
The IT400 has many connections all made through the bottom/mounting board. It is recommended to remove the battery when connecting wires to the connectors and when plugging the connectors into their sockets.

Wiring

In order to maintain the rated CE marking, the following practices must be followed:
All wires connected to the IT400 must be shielded (exception: SI supplied signal cable). o All shields must be connected to one of the internal mounting screws to achieve their
ground connection.
o It is recommended that the non-IT400 end of these shields is left unconnected. This
will help avoid ground loops and unexpected behavior.
o It is recommended that only one spade type terminal be used on each of the screws.
Care should be taken to avoid shorting any spade with other circuitry on the mounting board. If a longer screw is needed to attach the shielding spade, then the screw must be chosen to ensure at least one extra thread of space behind the screw. The hole depth is approximately 0.250 inches.
o Shields should not cover more than one pair of signal wires at a time.
The IT400’s chassis must be connected to an earth ground via the screw attached to the
outside of the unit. At least a 12 AWG preferably green wire is recommended.
All connections are to be made to the unit via rigid conduit.
All connected wires must not exceed 98’ length.
DC powered devices requiring the CE marking must be 4-20mA loop powered.
If no wires are required for a particular installation; the only requirement is the chassis ground connection.

Battery Removal and Installation

Battery Replacement:
- E8010 from Liquid Control s Sponsler, Inc.
- TL-5930/F from Tadiran Batteries, Ltd.
Battery Removal: reset the totalizer appears, the totalizer/grand totalizer/service timer will be saved to memory. Using two fingers inserted in the slots on the top and bottom of the main board overlay, gently rock the board top to bottom while pulling straight out. If this is done too quickly or unevenly, the main board will be damaged. After the main board is removed, the battery is accessible by opening the hook-loop strap. Once the battery is loose, the battery clip is removed by compressing the locking tab on the connector (locking tab is on the top of the connector {J3}) and pulling it out. Battery installation: Reverse the pr ocess for installation. Ensure the battery connector key is in the proper orientation pri or to inser ti on.
The internal battery may only be replaced with one of two batteries:
Unscrew the IT400 cover, press and hold the menu button until the option to

IT400 Operational Overview
The IT400 flowmeter system will perform the necessary calculations to provide the user with an optional temperature compensated and optional linearized output of the following values:
Rate
Total
Grand total
Errors/warnings
Various outputs

Calibration

Calibration of the IT400 is accomplished using either a linear K-Factor (pulses per gallon) or a linearized K-Factor linearization table (when the linearizer is enabled). Independent unit conversion factors and decimal points are available for the rate and total displays. Calibration and configuration data are stored in an onboard EEPROM for permanent storage. Calibration of the IT400’s reference circuitry is factory set and is not user accessible. Calibration of the IT400’s reference circuitry should be performed by factory trained service personnel.

Temperature Compensation

The temperature compensator utilizes a platinum RTD to detect the process temperature. Process temperature is used in conjunction with the reference temperature and Coefficient of Thermal Expansion of the measured liquid (menu items) to adjust the rate and total values. When the temperature compensation is enabled, the temperature warning annunciator (thermometer on the LCD) will indicate when the process temperature is out of a programmable range. Optionally, an alarm output as well as a totalizer inhibit function can also be tied to this temperature warning. Various Coefficient of Thermal Expansions and their reference temperatures can be found in the appendix. The temperature circuit and associated algorithm, when enabled, increase the IT400 current consumption fr om the power source and diminish battery life if running solely from the battery. A programmable delay function has been provided in order to minimize the impact of the temperature sampling on the battery life. The delay feature specifies the number of seconds between temperature value samples. The higher the delay, the longer the battery will last.

Linearization

The linearizer utilizes a linear interpolation algorithm to calculate the rate and total based on a set of calibration data points pr ogrammed by the user. The linearizer has21 points, the first point (lowest) is automatically set at zero hertz, the remaining 2 to 20 are user programmable. The linearizer table must have at least two data points in addition to the first (fixed) point and must be ascending in frequency from the first point to the last. To have fewer than 20 points in the linearizer table, after the last desired linearization point add one additional point and set the frequency at zero. Zero is an invalid frequency; this will indicate the end of the table. The IT400 will not allow frequencies to be entered out numerical order. Frequencies between zero and the first programmed point will use the K-Factor of the first programmed point.

LCD Display

The LCD display has three main areas: The 8 digit totalizer, 5 digit rate indicator, and the annunciators.
The 8-digit totalizer shows the total number of units of volume through put of the flowmeter since the last time the totalizer was reset. The totalizer is resettable by 2 methods, via a magnetic reed sw it ch in the lower left side of the unit and by menu. Th e grand total is displayed as long as a magnet is placed near the top of the face of the unit. The word "GRAND" indicates the displayed value is the grand total. Grand should be activated prior to battery replacement to save total/grand total values to non­volatile memory. Engineering unit annunciators display the units and decimal place selected to compute total and grand total values. The grand totalizer uses the same engineering unit as programmed for the totalizer.
The 5-digit rate display shows the rate of the flowmeter throughput. If the rate exceeds the high flow warning setpoint, "-oL-" is displayed. “-UL-“ is displayed when the rate is less than
the low flow warning setpoint. The warning is displayed until flowrate within these setpoints resumes. The totalizer is not affected by this warning unless programmed to inhibit totalizer when out of range. The range limits are established by the flow warning setpoints (Warning menu) in the menu system. Indicators on the display also show the engineering units of volume, time and decimal place used to compute the rate value. Note: When the Grand Total magnetic reed switch is activated (and GRAND is displayed on the screen), the rate display will display the current rate regardless of the range limits. This is helpful when troubleshooting flow condition problems when the low rate setpoint is set above zero.
Refresh rate of the display of the unit happens at pre-determined intervals depending on the selected power mode (see “Power”). Once the power mode is programmed (in the menu), the refresh rate is fixed. This prevents a low refresh rate from being automatically selected which could cause measurement delay.
Other display annunciators. These are warning indicators and do not inhibit the operation of the unit (unless explicitly enabled to do so by the alarm opti o n). These indicators may however indicate the condition causing an inaccurate reporting of rate or total information.
o Wrench – The service annunciator is user programmable to a specific amount of
“turbine hours” (activ e flowmeter hours).
o Thermometer – The thermometer annunciator is displayed continuously any time the
temperature compensator is enabled and the process temperature is out of range.
o Battery – The battery annunciator is composed of two segments. The segments
indicate the level of the battery charge, like an automotive gas gauge.
Two segments – The battery is within normal operating voltage range. One segment – A replacement battery should be acquired and installed. This will
also cause high temperature range on the temperature circuit to be reduced.
