FLOMEC 1-4-2022 QSI Module

INTRODUCTION

The QSI communications module is a multiple-capability electronics package. For the QSE meter, the module is available with the plain cover plate only. The QSI module has three versions (QSI1, QSI2, or QSI3) available; each with its own mix of capabilities to better serve the customer (See Versions below).

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

NOTE : The coil/digital input connections are for use with equipment other than a QSE meter. QSE meters automatically provide coil/digital pulse input via the 10-pin ribbon cable from the AFE PC board.
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

INSTALLATION

CAUTION : Installation near high electromagnetic fields and high current fields is not recommended and may result in inaccurate readings.

If you ordered your QSI module electronics with a QSE meter, it is installed at the factory. If you ordered your QSI module electronics separately (i.e. repair part), follow the instructions below to install them on a QSE meter. If you ordered your QSI module with one of our several types of meter adapter kits, follow the separate instructions enclosed with the kit to install the unit. In every case, please review and thoroughly understand all manuals and installation instructions before proceeding.

To mount your QSI module to a QSE meter:

Install the cover plate seal.
Connect the QSI module PC board connector to the AFE module PC board connector inside the meter housing with the ribbon cable. The ribbon cable connectors are polarized and cannot be incorrectly connected (see Figure 1).
Install the cover plate with screw holes aligned.
Install the (6) cover plate screws and tighten them. Make sure the cover plate seal is fully seated before tightening the screws.

A ribbon cable connects the QSI electronics within the cover plate to the AFE electronics within the meter body and allows 180 degrees of movement in either direction (see Figure 2).

WIRING
The cover plate has four threaded ports, compatible with PG7 threads, for gaining wiring access to the electronics inside the cover plate. The meter is shipped with the ports environmentally sealed with a threaded plug and seal. Remove one or more of these plugs as required to install the supplied port fittings below.
Each meter is supplied with cable gland strain reliefs with O-rings and 1/2 NPT adapters with seals for use in the threaded ports of the meter cover plate. Select the port fittings that fit your process and replace the threaded plugs in the cover plate with the fittings as required. The threaded plugs installed at the factory may be left in any unused cover plate port indefinitely.
It is recommended that a “removable” thread-locker (fluid, stick, tape, spray, etc.) be used when installing the strain reliefs or adapters into the cover plate ports.
Strain Reliefs
The cable gland strain reliefs will accommodate a cable diameter of 0.11 – 0.26 inches (2.79 – 6.6mm) and provide an environmental seal around the cable when the dome-nut is tightened.

NPT Adapters
The 1/2 NPT adapter fittings are used for attaching flex conduit to the meter, for those applications that require cable runs to be enclosed in conduit.
NOTE: Cable to be provided by customer to accommodate job requirements. Cable is not included with meter.

ISOLATED POWER SUPPLY WIRING
The QSE meter has an internal connection to the conductive fluid through one of the electrodes. The fluid and/or plumbing in most applications should be earth grounded to prevent any static buildup and provide a proper grounding for the system. Therefore, the power supply connection to the QSI should have an earth ground isolated output to prevent ground loop currents. Failure to use an isolated power supply could result in ground faults and could cause accuracy issues caused by stray voltages due to the ground loop currents. Proper grounding is a requirement.
The wire gauge for the power supply cable should be between 16 to 26 AWG to properly fit in the wire termination connector. The external power supply used for supplying power to the QSI should be rated for a minimum of 0.25 Amps.
The power supply polarity is not a requirement for the DC supply as long as the supply is properly earth ground isolated.

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

TEMPERATURE PROBES

If you ordered a QSI1 or QSI2 electronic choice with the temperature probe option, the correct length probes with cables are installed near the inlet and outlet ends of the meter. The cables are not connected to the QSI PC board. If you are installing a temperature probe retrofit kit, you will need to install the probes on the meter.

CAUTION : The temperature probes are not NSF certified. Installation of temperature probes will invalidate NSF approval.
Enclosed with your meter is a stainless steel pipe plug. It will be used during the set-up process.

INSTALLATION

NOTE : The meter should be installed in the system return line for accurate BTU calculations.
Each of the (2) temperature probes has a 10 ft. cable. The threaded body of the probe has 1/8” NPT threads to fit a standard 1/8” NPT port (see Figure 11).
The cable used with the probes has a smaller diameter than the standard strain reliefs (black), installed on the meter at the factory, will allow. Therefore, (2) reduced fit strain reliefs (gray) are included with the probes. For probe cable entry through the ports of the meter cover plate (to wire the system) replace (2) of the (black) strain reliefs in the cover plate with these reduced fit strain reliefs. The entire cable length is used for each probe installation. Both cables require a matched length.
Typically, a temperature probe is installed initially in each of the 1/8” NPT ports of the meter to calculate the differential between the two probes, if any.
The differential is captured and shown in the Android application as “Temp 1” and “Temp 2” and is used in the BTU calculations to ensure an accurate calculation.
For clarity, one probe is considered PT100 #1 and is connected to the meter PC board in that location. It is shown as “Temp 1” in the Android application.
The other probe is then considered PT100 #2 and is connected to the meter PC board in that location. It is shown as “Temp 2” in the Android application.
To perform the differential check, the probe installed in the 1/8” NPT port near the meter outlet end should be considered PT100 #1.
The probe installed in the 1/8” NPT port near the meter inlet end should be considered PT100 #2.
See Figures 5 and 7 for wiring diagrams.
After wiring the probes to the correct terminal of the PC board, perform the differential check.
NOTE : Use thread sealant on the male threads of the probes when installing in either the meter ports or system port.
After performing the differential check, remove the PT100 #2 probe near the inlet end of the meter and install the pipe plug, received with your meter, in the open meter port. Install the removed probe in the system supply line.
NOTE: Use thread sealant on the male threads of the pipe plug when installing it in the meter port.
During normal system operation, probe PT100 #1 is installed at the meter outlet end and probe PT100 #2 is installed in the system supply line. Accurate system BTU usage is calculated between the (2) probes.
The excess cable from the PT100 #1 probe (on the meter) to the cover plate may be coiled and secured using plastic quick ties.

WIRING
See Figures 5 and 7 for wiring diagrams. FLOMEC-1-4-2022-QSI-Module-
FIG-11

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 re-seat 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
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. To Replace Battery:

DISCONNECT POWER TO METER

Remove (6) screws retaining the cover plate to the meter body and lift the cover plate free of the meter body (see Figure 12).
Flip the cover plate over and remove (4) screws retaining the PC board assembly (see Figure 13).
Remove and replace the coin cell battery (CR2032) on the backside of PC board (see Figure 14).
Reverse the procedure to reassemble the cover plate to the meter. Make sure the cover plate seal is seated before tightening the (6) cover plate screws.
