SymCom’s PumpSaver
commonly used in duplex pumping applications to balance the run time of two pumps (loads). The
voltage designation must be specified in the part number.

The ALT-XXX-1-SW gives the user the option to allow the unit to automatically select the load, to
balance the run time of the two loads, or to manually select Load 1 or Load 2. This gives the user the
option to force one load to be the lead at all times when one load has been removed for maintenance
or repair.

An additional feature is the ability to output to two remote indicator lights.

READ THESE INSTRUCTIONS ENTIRELY BEFORE INSTALLATION.

Model ALT-XXX-1-SW is designed to alternate between two loads. It is

CONNECTIONS

1. The ALT-XXX-1-SW requires an 11-pin socket part number OT11 (sold separately).

2. Mount the PumpSaver
If the location is wet or dusty, it should be mounted in a NEMA 4 or 12 enclosure.

NOTE: The ALT-XXX-1-SW can be connected in many different ways using many different
switching devices. The following is a typical configuration for alternating between two pumps
and two indicator lights. See Figure 2 for a typical wiring diagram showing the following
connections.

3. Connect one pump’s magnetic contactor coils (M1) between socket terminal 11 and L2 of
the power supply.

4. Connect the other pump’s magnetic contactor coil (M2) between socket terminal 9 and L2
of the power supply.

5. Connect the indicator light for M1 (LT1) between socket terminal 3 and L2 of the power
supply.

6. Connect the indicator light for M2 (LT2) between socket terminal 1 and L2 of the power
supply.

7. Connect the power supply L2 to socket terminal 8 and power supply L1 to socket terminal

4.

8. Connect the control switch device between the power supply L1 and the socket terminals
10, 2, and 6.

9. Plug the Model ALT-XXX-1-SW into the socket.

SETTINGS

Figure 3: User-Selectable Options

The unit itself has one adjustable setting for load selection. Any additional configurations must be set
by connections to user-selected external switches.

To let the unit automatically select the load to be activated next, set the dial to “AUTO”. Turn the dial
to the selected load to allow only that specific load to be activated. This de-activates the other load if
it is currently activated. This allows one pump to be taken out of the circuit for repair or replacement.

Lock-out power to the ALT-XXX-1-SW before attempting to repair or replace

wiring or loads

OPERATION

Apply power to the system. Indicator lights on the unit will show which load is currently active.
Output to the corresponding remote light will also be activated.

When set to “AUTO”, the active load will continue to run until the control switch is opened. Each time
the control switch is opened, the output contacts will switch to activate the opposite load and light
the next time the control switch closes.

SOLUTION

Measure the line voltage. If the voltage is
below the minimum listed in the Specification
Table, the PumpSaver
power to operate its internal electronics. If the
voltages are correct, call SymCom at (800)
843-8848 or [phone].

Check the adjustment knob setting on the ALT­XXX-1-SW to make sure it is set to the AUTO
position.
