FLOMEC 1” OM Stainless Steel Flange Flowmeter Instruction Manual

This instruction covers the installation of the “no display” electronic module with QSI1, QSI2, or QSI3 versions of communications electronics installed. The basic mechanical installation is the same for all electronic modules. The wiring connections and wiring diagrams differ depending on the electronic module being installed.

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.

INSTALLATION

NOTE: For ALL QSI electronic modules.

Make sure the QSI module and meter are disconnected from power source.
Remove the circular plate (or other product) from the top of your OM meter. It will be replaced with the module components.
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).
Install the O-ring received with the module in the O-ring gland on the bottom of the base; mount the base to the OM meter and secure with (4) metric screws provided with the module. Tighten screws.
Make sure the seal is in place on top of the base prior to routing the wiring from the meter.
Route the wiring from the meter up through the base and connect the wires to the QSI PC board screw connectors, (see Figure 4, 8, or 10 depending on your module version).
To route external power and/ or electronic cables to the QSI PC board screw connectors, prepare the cover late by removing the plug and sealing washer from each port you intend to use. Replace the removed plugs with a strain relief with O-ring. The strain relief will accommodate cable sizes of 0.11 in. (2.8 mm) through 0.26 in. (6.6 mm) diameter.
(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.
Connect cable wires to the QSI PC board screw connectors (see Figure 4, 8, or 10 depending on your module version).
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.
Connect power to QSI module and meter.

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.

To replace battery:

DISCONNECT POWER TO METER
Remove (6) screws retaining the cover plate to the base and lift the cover plate free of the meter body (see Figure 13).
Flip the cover plate over and remove (4) screws retaining the PC board assembly (see Figure 14).
Remove and replace the coin cell battery (CR2032) on the backside of PC board (see Figure 15).
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.
