MODE D'EMPLOI 61F-GPN-BT OMRON

Conductive Level Controller

61F-GPN-BT/-BC

Battery (24 VDC) allows use in locations without AC power supply. AC sine-wave voltage between electrodes enables stable detection with no electric corrosion.

• Outputs can be set to self-hold at ON or OFF using special circuits.
• Adjustable sensitivity, with an operating resistance range of 0 to 100k , allows use for a wide variety of liquids.
• Relay contact chattering conventionally caused by waves eliminated using open collector output, reducing contact wear.
• Bears CE marking and is a UL recognized component.

Features

The 61F can now run on DC power to allow energy savings, greater safety, and use in emergency situations.

Combines DC Power Supply with AC Sensing Method

AC sine-wave signals are sent to electrodes using a built-in DC-AC converter, preventing electric corrosion and ensuring safety.

Open Collector Output Signals can be used as direct input for a PLC. PNP output is also possible using the connection method.

Supports Multi-channel Sensing

Power supply circuits and detection circuits are isolated, allowing more than one Controller to be used in the same tank.

Same Wiring for Supply and Drainage

Supply control and drainage control can be performed with the same wiring (short terminals 7 and 8 for supply control). This makes it easy to perform wiring and confirm connection.

Connections

Automatic Drainage Operation

Note: The part within the dotted-line box is for the 61F-GPN-BC (relay-output type) only.

Automatic Water Supply Operation

Short terminals 7 and 8 for automatic water supply operation. (Operation shown in parentheses in the diagram above.)

■ Reading Signals for the Liquid Level Only (No Control)

Only E1 and E3 are used. Output will turn ON when the liquid level reaches E1 if terminals 7 and 8 are open, and will turn OFF if terminals 7 and 8 are closed. Also, to take signals for liquid level at several points, use terminal 4 as a common for all of the Controllers and use terminal 5 of each Controller as an electrode.

Note: If terminals 7 and 8 are shorted, operation of the 61F relay is "de-energizing" (i.e., energized normally and de-energized when liquid is present across the electrodes). Therefore, if the power supply connected across terminals 3 and 9 is interrupted, the output from terminals 10 and 11 will turn OFF, enabling detection of power interruptions.

Dimensions

Application Examples

Drainage control for semiconductor wafer cleaning installations.

Liquid level control for solar power generation systems.

Meet safety standards by using DC power supply for all devices in a panel.

Liquid level control for waste-heat recovery boilers in co-generation systems.

Liquid level control for remote regions without AC power supply.

Cut costs by using the 61F in situations where ultrasonic/electrostatic capacity level controllers were used because only DC power supply was available.

General Precautions

Before using the Controller under conditions not described in the relevant documents or applying the Controller to nuclear control systems, railroad systems, aviation systems, vehicles, combustion systems, medical equipment, amusement machines, safety equipment and other systems, machines, and equipment that may have a serious influence on lives and property if used improperly, consult your OMRON representative.

Make sure that the ratings and performance characteristics of the Controller are sufficient for the systems, machines, and equipment and be sure to provide the systems, machines, and equipment with double safety-mechanisms.

Safety Precautions

In order to ensure safe operation, be sure to observe the following points.

• Use a power supply voltage within the specified range.
• Do not use the Controller in locations subject to flammable gases or objects.
• Insert the Socket until it securely clicks into place.
• Do not short the load connected to the output terminals.
• Do not connect the power supply in reverse.

Correct Use

Mounting

Mount to a panel of thickness 1 to 5mm

Do not mount the Controller in the following places.

• Locations subject to strong vibrations or shocks.
• Locations outside the specified temperature and humidity ranges, or locations prone to condensation. (The Controller detects high impedances. Do not use in locations subject to high humidity levels.)
• Locations subject to dust.
• Locations subject to corrosive gases (in particular, sulphurized gas or ammonia gas).
• Outdoors, or in locations subject to direct sunlight.
• Near devices that generate strong, high-frequency noise (e.g., high-frequency welders, machines).
