Alternate Operation Relay
61F-AN/-APN2
CSM_61F-AN_-APN2_DS_E_3_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 (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.

Time Chart for Alternate Operation of Water Supply
When the 61F-A@ Alternate Operation Relay is combined with a
Floatless Level Switch, 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 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 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 Switch.
Operation
•
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 S
0
and S
2
, NO
contacts Tc
1
and Ta
1
, and NO contacts Ta
2
and Tc
2
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 Tc
1
and Tb
1
and NC
contacts Ta
2
and Tc
2
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.

61F-APN2 (Compact Plug-in Model)
Used in combination with a Floatless Level Switch.
Operation
•
The 61F-APN2 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 2 and 7, NO contacts
1 and 3, and NO contacts 6 and 8 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 1 and 4 and NC
contacts 5 and 8 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.

Connections (Refer to connection diagram.)
•
Connect output terminal Ta in the 61F-G example (page 5) to input
terminal 2 on the 61F-APN2.
•
Connect coil terminal A on each of the two contactors to the
switching contact terminals 3 and 4 on the 61F-APN2.
•
Use the switching contact terminals 5 and 6 on the 61F-APN2 to
control the operation of the two pumps.
•
The power supply of the 61F-APN2 is 100, 110, 200, or 220 VAC.
Be sure to use the correct power supply.
