WARNINGS

Before removing, mounting, or wiring the AZBIL SPS300 A, be sure to turn off the power to the unit and all connected devices. Failure to do so might cause electric shock.

For safety, make a good connection to ground before connecting the AZBIL SPS300 A to the measurement target or external control circuits. Failure to do so might cause electric shock or fire.

CAUTIONS

PV value zero point and full-span point have been adjusted before shipment from the factory. Do not adjust these points again at installation. If these points must be adjusted, compensate by PV bias.

Wire the AZBIL SPS300 A according to the descriptions in the manual to ensure that the performance of the unit is fully exhibited.

Wire the AZBIL SPS300 A according to predetermined standards. Also wire the unit using designated power leads according to recognized installation methods. Failure to do so might cause electric shock, fire or faulty operation.

Use the AZBIL SPS300 A within the operating ranges recommended in the specifications (temperature, humidity, voltage, vibration, shock, atmosphere, etc.). Failure to do so might cause fire or faulty operation.

Do not disassemble the AZBIL SPS300 A, or touch components inside the unit. Doing so might cause electric shock or faulty operation.

Do not touch internal components during use or immediately after turning the power OFF. Doing so might cause burns.

If the AZBIL SPS300 A must be wired via a conduit, provide an appropriate conduit. Also, when the unit must be protected from the rain, provide a waterproof conduit, and properly seal unused conduit holes with plugs (supplied). Failure to do so might cause electric shock, fire or faulty operation.

Do not operate the keys with a mechanical pencil or other sharp-tipped object. Doing so might cause faulty operation.

Do not climb on top of the AZBIL SPS300 A or use it as a stand. Doing so might cause faulty operation.

Output (e.g., relay output contact operation or 4 to 20 mA operation) may be unpredictable for a brief moment when power is first supplied. Take preventive measures with the instrumentation to delay reception of the output signal to avoid any effects. Failure to do so might cause faulty operation of the equipment.

High accuracy: The accuracy for the display and output range, 4 to 20 mA, is ±0.25 % FS at 0 to 50 °C. It exhibits no temperature characteristics.

Pressure readings: Pressure values (PV values) are indicated by a 4-digit, 7-segment LED. The position of the decimal point can be moved rightwards to the minimum resolution range.

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

Relay contact output: Relay ON/OFF control is carried out by contacts according to the digital settings.

Digital settings: Relay contact and pressure differential set points can be input by key input while monitoring process pressures.

Keylock: The DISPLAY and PARAMETER mode details can be displayed and checked in the keylock state, but settings cannot be changed. This prevents inadvertent and erroneous setting.

Display digit: The display digit setting can be changed so that the last digit is hidden. This prevents flickering of the display caused by small pressure fluctuations.

Peak hold: The previous maximum pressure value can be stored in memory and checked when required. This value is cleared when the power supply is turned off.

Filter time constant change: Sudden fluctuations in PV value can be suppressed using a preset time constant.

HI/LO operation switching: The excitation direction of the relay can be changed. ‘HI’ for relay de-energized on pressure rise, energized on pressure drop. ‘LO’ for relay energized on pressure rise, de-energized on pressure drop.

PV bias: Process variables can be increased or decreased with preset values. This allows zero point adjustment to atmospheric pressure.

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

Current value manual output (SPS300A): Manually set pressure values can be output in order to check controllers and recorders during trial runs.

Self-diagnostics: Abnormal conditions are monitored by an integrated microcomputer so that remedial measures can be quickly carried out.

Entering numerical values with the DISPLAY key:

1. Move the focus to the left or right with the [◁], [▷], [▽], [△] keys.

2. Increment or decrement the value with the [△] or [▽] keys.

Locations where connector joints are subject to surge pressure.

Handling Precautions: Be sure to use the wall mounting bracket for the wall mounting model (Part No. 81446092-001) or the panel mounting bracket for the panel mounting model (Part No. 81446093-001).

Handling Precaution: Do not directly hold the unit when connecting the pipe to the pressure inlet. Doing so might damage the unit. Use a wrench to hold the hexagonal nut on the pressure inlet while tightening the pipe.

Correct connection: For both wall-mount and panel-mount models, use a wrench on the pressure inlet fitting to secure it while attaching the pipe with another wrench.

Incorrect connection methods to avoid:

Do not drop the unit.

Do not strike the unit.

Do not apply force by screwing-in, pushing, or pulling on the main body of the unit.

Do not install the unit upside-down or in a horizontal position.

Wiring Precautions:

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 (supply voltage: 100/120 V AC)

Type F 50 mA, 250 V AC fuse (supply voltage: 200/240 V AC)

Grounding:

Ground one point on the protective ground terminal.

Shielded cables should be grounded by connection to an earth bar.

Grounding type: Grounding resistance of 100 Ω max.

Grounding wire: Mild copper wire of more than 2 mm² (use crimp terminals compatible with M4 screws).

Grounding wire length: 20 m max.

General Wiring:

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

Devices and systems to be connected to this unit must have basic insulation sufficient to withstand the maximum operating voltage levels of the power supply and input/output parts.

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 that are compatible with M3.5 screws.

When installing in locations subject to much vibration or shock, be sure to use round terminal lugs that cannot come loose from the terminals.

Cable Installation:

Wire cables through the conduit holes. Use a waterproof conduit if needed (e.g., Seiwa Electric SC lock SK type).

The cable entry point should be lower than the conduit hole itself to prevent water drops from entering the unit by running along the cable.

2. Select the digit to be set by pressing the [◁] or [▷] key. The value of the blinking digit can be changed.

3. Set the desired value by pressing the [△] or [▽] keys. Each press increments or decrements the value. Pressing [△] at “9” rolls over to “0” and increments the next higher digit. Pressing [▽] at “0” rolls over to “9” and decrements the next higher digit.

4. When you press the [ENT] key after setting the desired numerical value, the digit blinks once, and then stops blinking to indicate that the value has been set. Control output is also executed at the same time.

5. To reset the value before pressing [ENT], press the [◁], [▷], [△] or [▽] keys.

Handling precautions: Since the value displayed on the PV display has been rounded to the nearest whole number, the relay may not operate even if the same value is displayed for the set point and the PV. The relay operates when the internally calculated PV value matches the set point.

Handling Precautions:

PV zero point and full-span point were adjusted before shipment from the factory. Do not adjust these points again at installation. If adjustment is necessary, use the PV bias.

When adjusting, follow the instructions below. If unsuccessful, initialize the settings using the “PV value zero point and full-span point adjustment initialization” function (PuI.n).

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

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