Alternate Operation Relay 61F-AN/-APN2 CSM 61F-AN -APN2 DS E 4 3 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 (61F- APN2) 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.

The Relay output contacts will not The next time the 61F Controllers NC contacts turn ON, the output switch simultaneously with engaging the contactor. In other words, contacts have already switched. Thus, only the continuous carry the contactor or other load is switched with the output contacts from current needs to be considered for the load capacity of the 61F- the Floatless Level Switch, not directly with the output contacts from APN2, enabling application to the rated carry current of 3 A. the 61F-A Alternate Operation Relay.

Operation The 61F-AN is used in combination with a Floatless Level Switch Tb1 Xc1 for alternate operation when using two pumps for level control in one location. Ta1 S0 When power is applied to the input terminals S0 and S2, NO Tc1 contacts Tc1 and Ta1, and NO contacts Ta2 and Tc2 are turned ON X via the alternate operation control circuit and the output circuit. This Tb2 Xc2 state is held with a magnetic lock even if the power supply is turned S2 OFF. Ta2 G2RK (See note.) When power is applied to the input terminals again, the NO (61F-AN) Tc2 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. Note: The above diagram is for a rated voltage of 200 or 220 VAC.
