Time Mark 441 Data Sheet

MODEL 441

TIME MARK is a division of

Multi-Stage

Alternator

 Replaces Mechanical Alternators

 User Selectable for:

• Single Motor/Pump

• Two Motor/Pump (duplex)

• Three Motor/Pump (triplex)

• Four Motor/Pump (quadraplex)

 Unit Remembers Which Motor/Pump
Is Next During Power Loss

 First-On, First-Off Operation

DESCRIPTION

The Model 441 Multi-Stage Alternator is designed to
control the operating sequence of multi-stage motor/
pumping systems. It can also be used to maintain the
desired level of pressure-on air compressor systems. Four
motor select DIP switches located on the front panel allow
the alternator to control a single-motor/pump, two-motor/
pump, three-motor/pump or four-motor/pump system.

The Model 441 will assure that only the necessary motors/
pumps are operating, and that the run time for each motor/
pump is approximately equal. Motors are sequenced “first­on, first-off”. If the motor/pumping demand requires only
one motor/pump at a time, the alternator will start the next
motor/pump in sequence each time an input switch is
closed. Input switches may be float switches, pressure
switches, flow switches, etc., as required by the
application.

Potential uses for the Model 441 include water supply
systems, sewage disposal plant systems, storage tank
filling systems, air compressor systems, irrigation and
water recycling systems.

READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.

KEEP THIS DATA SHEET FOR FUTURE REFERENCE.

GENERAL SAFETY

POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 441.

ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.

THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.

Installation Instructions

INSTALLATION

Switch Inputs

Input 1

Input 2

COM

Mount the Model 441 in an appropriate enclosure or panel.

Do not apply power until all other connections are made.

Connect the input switches (float, pressure, etc.) to the
terminals marked INPUT CONTACTS.

One side of each input switch is connected to the common
terminal; the other side should be connected to the input
terminals, starting with terminal 1.

Terminal 1 will be the first selected for either the pump up or
the pump down application. See the TYPICAL APPLICATION
diagram.

Connect the control circuits of the pumps or motors to be
alternated to the terminals marked OUTPUT CONTACTS.

Connect AC power connections to the terminals marked
Supply Voltage.

ADJUSTMENT

Set the motor select DIP switches to the ON position, for
every Motor/Pump connected to the Model 441 you wish to
enable.

If a pump or motor must be removed from service, set the DIP
switch to OFF for that motor/pump AND remove power from
the motor/pump.

PUMP DOWN APPLICATION

In a “Pump Down” application, the switches are normally­open. As the liquid level rises, the number 1 level switch
closes, turning on the first pump. If the level continues to rise,
additional pumps are turned on.

As the level drops, the pumps or motors are turned off on a
first-on/first-off basis. When the low level switch opens, the
Model 441 alternates to the next pump for the next operating
cycle. Switch number 1 determines when alternation occurs.

PUMP UP APPLICATION

In a “Pump Up” application, the switches are normally-closed.
When the reservoir is full, the switches will be open. As the
liquid level drops the number 1 level switch closes, turning on
the first pump. If the level continues to drop, additional pumps
are turned on.

When the level rises above the number 1 switch, the switch
opens, turning off the pump. The Model 441 then alternates to
start the next pump in line for the next operating cycle. The
number 1 switch determines when alternation occurs.
