Alternate Operation Relay 61F-AN/-APN2 CSM_61F-AN_-APN2_DS_E_4_1 Increases Motor Life and Enables Operating Only One Pump When Cleaning Tanks or as an Emergency Measure for Pump Failures. • Electronic Relay with the same operation as the G4Q Latching Relay. Compared with the G4Q, the 61F-AN/-APN2 has a shorter power supply application time and no restrictions on mounting direction. • Compact Models (61F-AN) and Compact Plug-in Models (61FAPN2) available. Note: A changeover switch must be included in the sequence to enable operating only one pump. Refer to Safety Precautions for Floatless Level Controllers. ■ Ordering Information Type Model Alternate Operation 61F-AN Relay 61F-APN2 Note: When ordering, specify the desired operating voltage at the end of the model number.

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 Switch, 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 61FAPN2, enabling application to the rated carry current of 3 A.

Operation S2 Tb1 Ta1 Output circuit S0 Alternate operation control circuit Xc1 Power circuit • The 61F-AN is used in combination with a Floatless Level Switch 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.
