INTRODUCTION

QSI

The QSI communications module is a multiple-capability electronics package and has three versions (QSI1, QSI2 or QSI3) available; each with its own mix of capabilities to better serve the customer (See Versions below).
The module is also available as a “display ready” version with no display installed, but ready for the customer to install their own GPI “09” display.

• QSI1: Equipped with Bluetooth®, coil/digital pulse input, pulse output (flow or energy & scalable), RS485 (Modbus® RTU), temperature inputs, and BTU calculator.
• QSI2: Equipped with Bluetooth, coil/digital pulse input, pulse output (flow or energy & scalable), temperature inputs, and BTU calculator.
• QSI3: Equipped with Bluetooth, coil/digital pulse input, pulse output (flow scalable), 4-20mA output.

This manual contains information and meter wiring diagrams for the three different QSI electronics modules.

IMPORTANT NOTICE

QSI module electronics are very sensitive to electric noise if operated within 6 inches of some electric motors, relays, transformers or other sources of electronic noise.
If the QSI electronics are used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

GENERAL INFORMATION
QSI electronics are available factory installed on designated meters, or as modules that will adapt the electronics to other FLOMEC meters.
The QSI electronics convert the voltage (or pulses) from the meter into usable information to support the various capabilities of the modules. The modules also supply the display (when installed on display-ready versions) with the information and power it needs to function as designed.
The QSI module electronics are powered by a customer-supplied external power.

SAFETY

This product is not approved for use in hazardous locations.

• Be sure the O-rings and seals are kept in good repair.
• When applying power, adhere to the specifications in this manual.
• Disconnect external power before attaching or detaching input or output wires.

ASSEMBLY INSTRUCTIONS

NOTE: For DISPLAY READY QSI electronic modules only.
For the “Display Ready” QSI module, follow these initial instructions first to install your customer-provided display to the cover plate in the kit. Then follow the Installation  Instructions to install this customer-assembled unit to the meter

1. Make sure the QSI module and meter are disconnected from the power source.
2. Remove batteries from your display, they will no longer be needed.
3. Remove the pickup coil from the back center of your display by cutting the two wires that attach it to the display. Cut the wires as close to the display as possible to ensure the cut ends do not touch the PC board inside the QSI module. Discard the removed coil.
4. Using a small regular screwdriver, remove the clear sealant from the 10-pin female connector holes on the backside of your display.
5. Insert the “long legs” of the 10-pin male connector that came with the kit into the 10-pin female connector on the QSI circuit board (see Figure A).
6. Install the formed display seal into the seal gland on the backside of the display.
7. CAREFULLY mount the display onto the cover plate ensuring the legs of the male 10-pin connector are inserted into ALL 10 pin female connector holes of the display (see  Figure B).
8. Secure the display to the cover plate using the four #4-20 x 7/8 in. tapping screws. Torque to 80-96 oz-in (0.56-0.67 Nm).

INSTALLATION

NOTE: For ALL QSI electronic modules.

1. Make sure the QSI module and meter are disconnected from the power source.

2. Remove any attached product, if it exists, from the top of your G2 meter. It will be replaced with the module components.

3. Remove the (6) #8-16 x 3/4 in. screws attaching the module cover plate to the base and separate. Do not damage the seal between the two components (see Figure 2). The  (2) wires connecting the QSI PC board to the screw terminal of the pick-up circuit board are long enough to allow the separation of parts. The wires may be disconnected from the screw terminal if necessary. The wires are nonpolarized and may be connected to either screw of the screw terminal (see Figure 4).

4. The module was packaged with the pickup coil in the unseated position to prevent coil damage during shipping. The coil has a foam spacer attached. Remove the liner from the foam spacer to expose the adhesive layer and install the spacer/coil into the adapter recess (see Figure 2).

5. Install the gasket received with the module on the bottom of the base. Mount the base to the G2 meter, seating the pick-up coil in the meter recess. Secure base with (4)  screws provided with the module. Tighten screws.
   NOTE: Use #4-40 screws for metallic meters or #4-20 Plastite® screws for PVDF meters.

6. Make sure the seal is in place on top of the base prior to reattaching (if previously disconnected) the (2) wires to the screw terminal of the pick-up circuit board.

7. To route external power and/or electronic cables to the QSI PC board screw connectors, prepare the cover plate by removing the plug and sealing the washer from each port that you intend to use. Replace the removed plugs with a strain relief w/O-ring. The strain relief will accommodate cable sizes of 0.11 in. (2.8 mm) through 0.26 in. (6.6 mm)  diameter. Leave the factory-installed plugs in any unused ports.

8. (Make sure the power is disconnected from external cables before beginning this step): Route external cables through the strain relief(s), and then tighten the dome nut securely around the cable to provide an environmental seal.

9. Connect cable wires to the QSI PC board screw connectors (see Figures 4, 6, or 8 depending on your module version).

10. Mount the cover plate on the base making sure the seal is seated properly between them. Replace the (6) previously removed screws to secure the cover plate to the base. Tighten screws.

11. Connect power to the QSI module and meter.

NOTE: The below figure is for all QSI electronic modules, even though the “display ready” version is not shown in the pictorial.3

*NOTE: It is not recommended to connect isolated ground connections together or to board commonly.
**NOTE:** Polarity of voltage for DC is not important. However, an earth- ground isolated power supply is required to prevent earth-ground loop currents and ground fault conditions.
***NOTE:** This output may require an external pull-up resistor if interfacing equipment does not include one.

Note: Either of the wiring diagrams below (Low Side Negative Wiring- Figure 10A) or (High Side Positive Wiring-Figure 10B) are valid, as long as the current direction arrows and the (+) and (-) connections on all of the equipment in the loop are correct.

MAINTENANCE

Check cable-entry seals periodically. Tighten and/or apply sealant if needed. This is especially important in environments containing heavy concentrations of dust, oil mist, or another residue.
Check all wiring connections occasionally for oxidation or corrosion. Clean and reseat if such conditions are noted.
If necessary, check and re-seat any connections that may have been subjected to strain (during rework or construction, for example).

REPLACING BATTERY

NOTE: The QSI2 and QSI3 communications module has a 3V lithium coin cell battery installed on the PC board. In case of power failure, the battery functions as a power backup to maintain the internal system time. Any QSI2 or QSI3 feature that uses a time reference as part of its functionality will be immediately accurate to the current time when power is restored.

To replace the battery in “NO DISPLAY” MODULE:

• DISCONNECT POWER TO THE METER
• Remove (6) screws retaining the cover plate to the base and lift the cover plate free of the base (see Figure 11).
• Flip the cover plate over and remove (4) screws retaining the PC board assembly (see Figure 12).
• Remove and replace the coin cell battery (CR2032) on the backside of the PC board (see Figure 13).
• Reverse the procedure to reassemble the cover plate to the base. Make sure the cover plate seal is seated before tightening the (6) cover plate screws.

To replace the battery in “DISPLAY READY” MODULE:
NOTE: On units with a display, only the display needs to be removed to replace the coin cell battery. The battery is accessible through the opening where the display is installed  (see Figure 14).

• DISCONNECT POWER TO THE METER
• Remove (4) screws retaining the display to the cover plate. Lift the display straight up to disconnect the 10-pin bridge connector. The bridge connector could disengage from either the socket connector (display or PCB assembly) or both.
• Remove and replace the coin cell battery (CR2032).
• Reverse the procedure to reassemble the display to the cover plate. Make sure the display seal is seated before tightening the (4) display screws.
