Automatic Water Supply and Drainage Control 1. Water supply  Connect electromagnetic switch coil terminal A to Tb.  The pump stops when the water level reaches E1 and starts when the water level drops below E2. 2. Drainage  Connect the electromagnetic switch coil terminal A to Ta.  The pump starts when the water level reaches E1 and stops when the water level drops below E2. Note: 1. The diagram shows the connections for water supply. When draining, change the connection Tb to Ta. 2. The earth terminal must be grounded. Operation The conductive type level controller consists of a plug-in controller connected to a set of stainless steel probes. These are cut to length and inserted vertically into the liquid. A low voltage is applied between these probes and the earth probe (or tank, if it is electrically conductive). The water provides a current between the earth probe and the high-level probe. The output relay in the controller is ener- gized when the water level reaches the high-level probe and de-ener- gized when the water level falls below it. For two-point control a low-level pr obe is used as well. In this case the relay does not de-energize until the water level falls below the low-level probe. Using the low-level probe allows a wide differential between switching a pump on and off, and can avoid excessive pump operation during tank emptying or f illing. If this differential is not required, the low-level probe need not be connected. Dimensions Note: All units are in millimeters unless otherwise indicated. 7E1 Ta Tb Tc Power source 220 or

■Electrode Separators F03-14 1P (for Single Pole) F03-14 3P (for Three Poles) Precautions ■How to Mount Electrodes Connecting Electrodes to Electrode Holders Connecting One Electrode to Another ■Application When using electrodes in sea water or sewage, provide a sufficient interval (normally 1 m) between t he electrodes. If the sufficient inter- val cannot be provided, employ a low-sensitivity type Floatless Level Controller. When taping one of the electrodes to prevent it from contacting the other electrodes in water, do not tape the electrode entirely but leave at least 100 mm of its end uncovered. When the required length of the electrode is more than 1 m, use a separator at each joint of two electrodes so as to prevent the elec- trodes from contacting one another. (NOTE: Avoid use of the separa- tors in dust-containing liquids.) Usually, electrodes are used in a se t of three: long, medium, and short. Connect the short electrode to E1, the medium electrode to E2, and the long electrode to E3. Make E3 at least 50 mm longer than E2. Electrodes are in actual contact with the liquid. Standard electrodes are made of stainless steel and usable in purified water, sea water, sewage, acid (except acetic acid, su lfuric acid, etc.) and alkaline liq- uids, although they may corrode depending upon the temperature and working conditions. Note that the Conductive Level Controller 61F-GP-N2 is capable of controlling liquids with specif ic resistances of up to 30 k Ω-cm when the controller employs a type PS-3S electrode holder with the elec- trode(s) submerged to a depth of 30 mm max. 6.5-dia. 28-dia. 41-dia.

■Safety Precautions !WARNING !CAUTION Precautions for Safe Use 1. Precautions for the environment  Use and preserve within the proper temperature and humidity described in the specifications.  Temperature of surroundings for preservation (including during transportation) and use: −10 to 55°C, humidity: 45 to 85%.  Do not install, among others, near heat devices such as coils or other devices having coils, etc.  Avoid preserving (including duri ng transportation) and using in a humid place, in a corrosive gas environment, outdoors and in a place which receives direct sunlight.  Preserve and use without exposing to danger of explosion, flamma- ble dust, gas and vapor, excessive dust, and saline spray or drop- lets.  Avoid preserving (including duri ng transportation) and using in a place which is vulnerable to flooding or oil spillage.  Avoid preserving (including duri ng transportation) and using in a place where vibrations and impacts are strong. Similarly, avoid using next to a high-capacity contactor which may impacts at oper- ation. Doing so causes malfunctions such as chattering, etc.  Do not install the product near devices generating strong high-fre- quency waves or surges. When usi ng a noise filter, check the volt- age and current and install it as close to the product as possible. 2. Cautions for Use  Read the instruction manual and catalog before operating and maintaining the product.  Fit socket(s) and DIN rail(s) so that the screws are tight. If the screws are not tight, DIN rail(s), socket(s), the product and cable(s) may lead to come off.  Be sure to fit socket(s) to DIN rail(s) without fail.  Use metal strengthener(s) to main tain a firm connection between the product and socket(s).  Read the instructions manual and catalog before the operation and maintenance of the product.  When fitting crimping terminal(s) to terminal screw(s), use a tight- ening torque of between 0.45 and 0.6 N·m  Use power supply of appropriate spec ifications to provide control source(s), inputs, etc., and to wire cables. [Recommended cable to wire between the model 61F and elec- trode(s) when using three-core cabtire cable(s) of completely insu- lated 600 V 0.75 mm VCT: 50 m max.]  Do not put power line(s), high-volt age cable(s) and wire(s) of elec- trode circuit(s) in the same duct nor wire closely. Doing so causes malfunctions by getting vulnerable to induction noise.  Shorten the distance for wiring between the model 61F and elec- trode holders as much as possib le. Long distance for wiring may causes malfunctions because stray capacitance may influence operation, or abnormal surges or noise may run through electrode circuit(s).  Be sure to ground common electr ode terminal(s). Doing so can reduce some effects of noise.  Use the product within the noted supply voltage and rated load.  Before using, recheck the application, wiring, power supply, etc.  Check the application and power supply. Power supply (AC 220 V, AC 230 V) consists of other specifications. If the power voltage is not AC 200 V or AC 100 V, follow the instruc- tions described on the device.  Firmly ground the earth terminal No.4.  Make sure that electrode probes in the liquid do not come in con- tact one another as it may cause malfunction. Use separator when connecting.  Tighten nuts for electrode probe(s) firmly.  Prevent flotage from attaching to electrode.  This device is not available when the resistance is too high and is not conductive such as oil. Do not touch the terminals while power is being supplied. Doing so may possibly result in electric shock. Make sure that the terminal cover is installed before using the product. Do not attempt to disassemble, repair, or modify the product. Doing so may occasionally result in minor or moderate injury due to electric shock. In the interest of product improvement, specifications are subject to change without notice.
