61F-AN/-APN2When power is applied to the input terminals 2 and 7, the power willbe transmitted through the alternate operation control circuit and out-put circuit to turn ON the contacts (NO condition) between 1 and 3and between 6 and 8. This state will be held by a magnetic lock evenwhen the power to the input terminals is turned OFF.
When power is again applied to the input terminals, the contact (NOcondition) will turn OFF and the contacts (NC condition) between 1and 4 and between 5 and 8 will turn ON. This state will be held evenwhen the power to the input terminals is turned OFF.
The above operation repeats each time power is applied to the inputterminals (power application pulse response system). Refer to thefollowing internal circuit diagram.
Time Chart for Alternate Operation of Water SupplyWhen the 61F-A@ Alternate Operation Relay is combined with a Floatless Level Controller, the Relay output contacts switch (break) while the contactor is engaged. The Relay output contacts will not switch simultaneously with engaging the contactor. In other words, the contactor or other load is switched with the output contacts from the Floatless Level Controller, not directly with the output contacts from the 61F-A@ Alternate Operation Relay. Using water supply as
an example, after the control level is reached and the 61F Controllers’ NC contacts turn OFF (break), the Relay’s output contacts switch. The next time the 61F Controller’s NC contacts turn ON, the output contacts have already switched. Thus, only the continuous carry current needs to be considered for the load capacity of the 61F-APN2, enabling application to the rated carry current of 3 A.
61F-AN (Compact Model)Used in combination with a 61F-G@N Floatless Level Controller.
Operation• The 61F-AN is used in combination with a Floatless Level
Controller for alternate operation when using two pumps for level control in one location.
• When power is applied to the input terminals S0 and S2, NO contacts Tc1 and Ta1, and NO contacts Ta2 and Tc2 are turned ON via the alternate operation control circuit and the output circuit. This state is held with a magnetic lock even if the power supply is turned OFF.
• When power is applied to the input terminals again, the NO contacts are turned OFF and the NC contacts Tc1 and Tb1 and NC contacts Ta2 and Tc2 are turned ON. This state is held with a magnetic lock even if the power supply is turned OFF.
• The above operation is repeated each time the power supply is turned ON. (Power Supply Pulse Response Method)

Safety Precautions for Floatless Level Controllers
!WARNING
Precautions for Safe UseDo not use the Controller in locations subject to explosive or combustible dust, combustible gas, flammable vapors, corrosive gas, excessive dust, salt water spray, or water drops.
Precautions for Correct Use● Operating Environment
• Use and store the Controller within the rated ambient operating temperature, ambient operating humidity, and storage temperature ranges specified for individual models.
• Use the Controller according to the characteristics specified for individual models for vibration, shock, exposure to water, and exposure to oil.
• Install the Controller as far as possible from devices that generate strong high-frequency noise (such as high frequency welders or sewing machines).
● Tighten Terminal Screws to the Specified TorqueWhen fitting crimping terminals to terminal screws, use a tightening torque of between 0.45 and 0.6 N·m
● Use a Power Supply with Minimal Voltage Fluctuation
Avoid connection to a power supply with a voltage fluctuation greater than or equal to +10% or 15%.
● Consider the Ambient Temperature
Do not install the Controller where it may be exposed to a temperature of 55 C or higher or a humidity of 85% or higher. In particular, install the Controller away from heat-generating equipment incorporating coils or windings. Do not use the Controller outdoors or in locations subject to high humidity, corrosive gases, or direct sunlight.
● Avoid Vibration and Shocks
Do not subject the Controller to vibration or shocks which can cause chattering problems. Do not install the Controller near contactors that generate severe shocks while the contactors are in operation.
● Do Not Test with a Megaohmmeter
During insulation resistance measurements, never apply the megaohmmeter across the Electrode terminals.
● Use Self-holding Electrodes
• Use Self-holding (E2) Electrodes when contactor open/close control is carried out. If E1 Electrodes are used, ripples on the liquid surface can cause incorrect contactor operation and damage to the contacts.
• Be sure to turn OFF the power supply before replacing the plug-in models.
● Short Wiring in Electrode Circuit
• Keep the wires connecting the Controller to Electrode Holders as short as possible. If long leads are used, the floating capacity of the leads, and abnormal surges or noise in the Electrode circuit can cause malfunctions.
• The thicker the cables, the shorter the permitted wiring length. The length of the cable connecting the Controller and Electrode is specified in the Controller datasheet as a guideline assuming that a 600-V VCT 0.75-mm2, 3-core cabtire cable is used. Test results indicate that the actual wiring length using VCT 3.5-mm2, 3-core cable laid over the ground is 50% of the specified length for
general-purpose applications and 80% of the specified length for long-distance applications. When selecting cable specifications, remember that the wiring length is further decreased for underground cables and larger diameter cables because of the increased floating capacity with the ground.
● Keep Power Cables Separate from the Electrode Circuit
Do not pass the leads for the Electrode circuit through the same duct, or near to, high-tension cables or power cables. This can cause noise which leads to malfunctions.
● Ground Correctly
Ground the common Electrode terminal to reduce the effects of noise.
● Use a Surge Suppressor
Connect a 61F-03B(-04B) Surge Suppressor with the Controller’s Electrode terminals to protect the circuit from surges. This is particularly important in lightning-prone areas. To further improve protection, install a commercial surge suppressor in the power supply to eliminate surges in the power system.(Refer to 61F-03B/-04B.)
● Consider the Response Times
The Controller requires a response time not exceeding 80 ms for operation or 160 ms for reset. Take these response times into account in cases where precise sequence control is required.
● Consider the Liquids to Be Controlled
• The Controller cannot be used for any liquid that has almost no conductivity such as sewage containing oil.
• The Controller cannot be used for any flammable liquid such as gasoline, kerosene, or heavy oil.
● Do Not Share Electrodes
Do not connect a single Electrode to more than one Controller. If the phases of the 8-VAC Electrode-circuit power supplies are opposite to each other, as shown in Fig. 1, an internal close circuit (return circuit) is created (indicated by the arrows). The Controller may malfunction regardless of the liquid level when the Controller power is turned ON. This problem can be overcome by matching the power supply phases, as shown in Fig. 2, but in this configuration the internal impedance of the Controller calculated from the Electrode will be approximately half as large as the internal impedance of a single Controller. Maintain sufficient clearance between Electrodes connected to separate Controllers so that they do not interfere with each other. Common leads, however, can be connected to the ground Electrode.
Do not touch the terminals while power is being supplied. Doing so may occasionally result in electric shock.
Do not attempt to disassemble, repair, or modify the product while the power is being supplied. Doing so may occasionally result in electric shock.
