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).

• QSI1 : Equipped with Bluetooth®, coil/digital pulse input, pulse output (flow or energy & scalable), RS485 (Modbus® RTU), temperature inputs, BTU calculator.
• QSI2 : Equipped with Bluetooth, coil/digital pulse input, pulse output (flow or energy & scalable), temperature inputs, 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 converts the voltage (or pulses) from the meter into usable information to support the various capabilities of the modules. The QSI module electronics are powered by customer- supplied external power.

SAFETY
This product is not approved for use in hazardous locations.

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

NOTE: For ALL QSI electronic modules.

1. Make sure the QSI module and meter are disconnected from power source.
2. Remove any attached products from the 1” male NPT fitting on top of your GSeries 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).
4. Screw the module elbow adapter onto the 1” NPT fitting on top of your G-Series meter, aligning the face of the base (still attached to the elbow) in desired direction.
5. Make sure the seal is in place on the face of the base prior to routing the wiring from the meter.
6.  Route the (2) wires from the meter sensor through the elbow adapter and out the face of the base. Snip ends to remove stripped wire. Connect either of the meter sensor wires to either wire from the QSI PC board using the enclosed butt-splice connectors (see Figure 2). Crimp connector to splice wires together and release insulation gel. Repeat with the remaining sensor and PC board wire (see Figure 4, 6, or 8 depending on your QSI version). (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.
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 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 reliefs, 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 terminals (see Figure 4, 6, or 8 depending on your QSI 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 QSI module and meter.

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 : It is not recommended to connect isolated ground connections together or to board common.
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 other 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 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.

• DISCONNECT POWER TO 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 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.

SERVICE
For warranty consideration, contact your local distributor. If you need further assistance, contact the GPI Customer Service Department at: 1-888-996-3837

You will need to:
