AZBIL SPS300 B (01) PDF DOCUMENT

WARNING

Before removing, mounting, or wiring the AZBIL SPS300 B, be sure to turn off the power to the device and all connected equipment to prevent electric shock.

For safety, ensure a proper ground connection is made before connecting the AZBIL SPS300 B to the measurement target or external control circuits to prevent electric shock or fire.

CAUTION

The PV value zero point and full-span point are factory-adjusted. Do not adjust them at installation. If adjustment is necessary, compensate using PV bias.

Wire the device according to the manual to ensure full performance.

Wire the AZBIL SPS300 B according to predetermined standards and with designated power leads using recognized installation methods to prevent electric shock, fire, or faulty operation.

Use the device within the specified operating ranges for temperature, humidity, voltage, vibration, etc., to avoid fire or faulty operation.

Do not disassemble the AZBIL SPS300 B or touch internal components to prevent electric shock or faulty operation.

Do not touch internal components during use or immediately after powering off, as they may be hot and could cause burns.

If wiring via a conduit, use an appropriate conduit. For rain protection, use a waterproof conduit and seal unused conduit holes with the supplied plugs to prevent electric shock, fire, or faulty operation.

Do not operate the keys with a mechanical pencil or other sharp objects, as this may cause faulty operation.

Do not climb on or use the AZBIL SPS300 B as a stand, as this may cause faulty operation.

Output signals (relay contact, 4 to 20 mA) may be unpredictable for a brief moment at power-on. Implement preventive measures in your instrumentation to delay the reception of the output signal to avoid equipment malfunction.

To reduce the risk of electric shock, follow all safety notices in the documentation. A symbol on the device warns of potential shock hazards from accessible live voltages.

If the equipment is used in a manner not specified by the manufacturer, the built-in protection may be impaired.

Do not replace any component not specified as replaceable.

All wiring must comply with local regulations and be done by authorized personnel.

Always wire the ground terminal first and disconnect it last.

Mount a power shutoff switch for the unit within reach of the operator.

For AC power models, install a fuse compliant with IEC 127 according to the power voltage:

100/120 V AC: Type F, 100 mA, 250 V

200/240 V AC: Type F, 50 mA, 250 V

For DC power models, use a power supply with reinforced insulation.

High accuracy: The accuracy for the display and 4 to 20 mA output is ±0.25% FS at 0 to 50 °C.

Pressure readings: Pressure values (PV) are shown on a 4-digit, 7-segment LED.

4 to 20 mA output: PV values are converted to a 4 to 20 mA output for either the full range or a preset span.

Relay contact output: Relay ON/OFF control is performed by contacts based on digital settings.

Digital settings: Set point and differential values can be entered via key input.

Keylock: Prevents inadvertent changes to settings while still allowing modes to be displayed and checked.

Display digit: The last digit can be hidden to prevent display flickering from small pressure fluctuations.

Peak hold: Stores the maximum pressure value in memory for checking. This value is cleared when power is turned off.

Filter time constant change: Sudden PV fluctuations can be suppressed with a preset time constant.

HI/LO operation switching: The relay excitation direction can be changed (HI or LO).

PV bias: Process variables can be adjusted with preset values, allowing for zero point adjustment to atmospheric pressure.

PV zero point and span adjustment: The zero and span points of PV values are adjustable.

Current value manual output (SPS300A only): Manually set pressure values can be output to check controllers and recorders.

Self-diagnostics: An integrated microcomputer monitors for abnormal conditions.

Avoid installing the AZBIL SPS300 B in the following locations:

Locations with temperatures outside the operating range of -20 to +60 °C.

Locations with humidity exceeding 90% RH.

Locations subject to sudden temperature changes and condensation.

Locations subject to corrosive or flammable gases.

Locations with large amounts of dirt, dust, salt, conductive substances (like iron powder), or organic solvents.

Locations where the device is directly subjected to vibration or impact.

Locations exposed to direct sunlight.

Locations with large amounts of water or rain.

Locations subject to splashing from oil or chemicals.

Locations where strong magnetic or electrical fields are generated.

Locations where connector joints are subject to surge pressure.

When connecting a pipe to the pressure inlet, do not directly hold the main unit. Doing so might damage the unit. Instead, use a wrench to hold the hexagonal nut on the pressure inlet while tightening the pipe.

Avoid the following incorrect connection methods:

Dropping the unit.

Striking the unit.

Screwing-in, pushing, or pulling on the main body of the unit.

Installing the unit in an upside-down or horizontal position.

To prevent electric shock on panel-mounted models, prevent direct contact with the terminals by the operator.

A switch in the main power supply is required within the operator’s reach.

For AC power models, install the proper fuse according to the supply voltage:

Type F 100 mA, 250 V AC fuse (for 100/120 V AC)

Type F 50 mA, 250 V AC fuse (for 200/240 V AC)

Ground one point on the protective ground terminal. Shielded cables should be grounded by connection to an earth bar.

Grounding should have a resistance of 100 Ω max, using a mild copper wire of more than 2 mm² (with crimp terminals for M4 screws) and a length of 20 m max.

If waterproofing is needed, seal the conduit hole with a waterproof conduit.

Separate low-voltage output signal cables from power cables with a voltage higher than 100 V. Do not put them in the same conduit or duct.

For wiring (not grounding), use crimp terminals with insulating sleeves compatible with M3.5 screws. For locations with high vibration or shock, use round terminal lugs that cannot come loose.

Be careful not to scratch electronic parts or lead wires.

Do not apply excessive force to the 3-pole terminal block.

Confirm the model number before connecting cables according to the correct diagram.

After wiring, check that it is correct.

Disconnect power before wiring, installing, or removing the device.

Calibrate pressure at least once per year.

This is a precision instrument; protect it from excessive shock during installation or operation.

The unit is not free-standing and must be firmly fixed to a mounting plate.

Do not hold the case while threading the pipe into the unit. Hold the hexagonal nut to secure it.

Install the AZBIL SPS300 B upright only. Horizontal installation may result in errors.

The device is rain-proof but should be installed away from direct sunlight or rain. Use a waterproof conduit if needed.

Do not apply excessive pressure, as it may cause drift.

Use caution when opening and closing valves, as pressure surges through non-compressible liquids can damage the sensor.

Protect liquid-contacting parts from freezing. Use insulation or heating if freezing is anticipated.

Reduce the pressure inlet temperature to 60 °C or lower by using a siphon for high-temperature media.

Wait at least 10 minutes after turning the power ON for the unit to stabilize.

Handling Precautions:

PV zero and full-span points are factory-adjusted. Do not adjust these at installation unless necessary; use PV bias instead.

If adjustment fails, initialize the settings.

Since the PV bias value is not adjusted by this procedure, reset it to zero before starting.

Reset the filter time constant to zero and adjust it after the PV value has stabilized.
