Flomec QSI Series, QSI1, QSI2, QSI3 Installation Instructions Manual

Adapter Kit - QSI Electronics to G-Series Meter

Installation Instructions

These installation instructions cover the adapter kit installation of the QSI1, QSI2 and QSI3 versions of communications electronics to G-Series Meters. The instructions are the same for QSI versions with or without a display. Check the contents of your kit using the list below as a reference. Make

sure the power to your G-Series meter is disconnected.

INSTRUCTIONS

1. Remove any attached products from the 1” male NPT tting on top of your G-Series meter. It will be replaced with the adapter kit components.

2. Remove the (6) #8-16 x 3/4 screws attaching the kit cover plate to the adapter and separate. Do not damage the seal between the two components (see Figure 1).

3. Screw the kit elbow adapter onto the 1” NPT tting on top of your G-Series meter, aligning the face of the adapter (still attached to the elbow) in desired direction.

4. Make sure the seal is in place on the face of the adapter prior to routing the wiring from the meter.

5. Route the (2) wires from the meter sensor through the elbow adapter and out the face of the adapter. 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 1). Crimp connector to splice wires and release

insulation gel. Repeat with the remaining sensor and PC board wire. See wiring diagram in these instructions.

6. To route external power and/or electronic cables to the QSI PC board screw terminals, prepare the cover plate by removing the mushroom plug from each strain relief you intend to use. The strain relief will accommodate cable sizes of 0.11” (0.28 cm) through

0.26” (0.66 cm) diameter.

7. 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.

8. Connect cable wires to the QSI PC board screw terminals per the wiring diagram in these instructions.

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