About this file
This document contains technical specifications and nameplate data for pumps and a liquid level controller for the Southeast Des Moines Pump Station rehabilitation project. The project involves rehabilitating the pump station located on the Des Moines River in Des Moines, Iowa. The pump station contains three pumps that will be replaced. Pump specifications include manufacturer, model, horsepower, flow rates, and other technical details. The document also provides installation and operation instructions for a Model 407 liquid level controller that will automatically control the three new pumps based on sensed water levels. The related federal contract opportunity is a solicitation from the U.S. Army Corps of Engineers seeking bids for the pump station rehabilitation project. The project is estimated to cost between $5-10 million and take 360 days to complete. Bids will be evaluated using lowest price technically acceptable criteria.

MODEL 407
Liquid Level Controller
Three pump operation
Three run-time meters
Selectable lead or automatic alternation
Five sensing levels
Alarm outputs
Hand-off-auto controls
DESCRIPTION
The Model 407 Liquid Level Controller provides central control of triplex pumping systems. The Model 407 includes pump alternating, visual run-time meters, hand-off-auto (HOA) controls and alarm outputs.
Five level-sense inputs interface with float switches, pressure switches, or other level sensing devices which can provide a contact closure.
A SPST, normally-closed internal power-fail contact opens when AC power 120VAC is connected to the controller, and closes if power is lost or removed. Connections for external remote alarm contacts, which must remain closed for normal operation (or jumpered if not required), are supplied for each pump.
If either circuit opens, the corresponding pump will be locked out until the problem is corrected and the ‘Alarm reset’ switch is pressed.

MODEL 407 Liquid Level Controller
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 407.
ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.
DO NOT EXCEED THE OUTPUT OR INPUT RATINGS, AS STATED IN THE SPECIFICATIONS.
PROTECT THE UNIT WITH PROPERLY RATED FUSES.
DO NOT INSTALL IN DAMP OR MOIST AREAS.
THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.
Installation Instructions
INSTALLATION
Mount the controller in a suitable enclosure. Unplug the terminal connectors from the controller.
Referring to the terminal block decal on the controller and the illustration on this page, make the following connections.
1. Connect a chassis ground to the terminals marked
AC GND.
2. Connect 115VAC operating power to the terminals marked 115VAC.
3. Connect the LOW float switch to the LOW terminals. Polarity is not critical.
4. Repeat step 3 for LEAD, LAG, LAG-LAG, and HIGH terminals.
5. The SIGNAL GROUND connection is a common between the controller and a Liquid Level Sensor, no connection is necessary if the sensor is not used.
6. The PUMP 1, 2, & 3 REMOTE ALARM terminals should be connected to normally closed (NC) alarm contacts in the motors. If none exist it is st i l l necessary to install a jumper connection between Pump 1, PUMP 2, & PUMP 3 REMOTE ALARM terminals.
7. The POWER FAIL, ALARM BELL, & ALARM LIGHT are not required for proper operation, but are provided for your convenience. If used, connect an audible/visual alarm across the terminals. The POWER FAIL contact is open while power is applied and closes on loss of power. Connect audible and visual a l a r m s across the ALARM BELL and ALARM Light terminals respectively. These contacts are normally open and will close on a fault (high or remote alarm) condition.
8. Connect the PUMP 1, PUMP 2, & PUMP 3 contacts to the appropriate motor control circuits.
These contacts start and stop the pump motors during operation.
Set the HOA (Hand-off-Auto) switches and the LEAD PUMP selector switch as required. Apply operating power. Test alarm LEDs and bells by pressing the ALARM TEST switch.

WARRANTY
This product is warranted to be free from defects in materials and workmanship for one year. Should this device fail to operate, we will repair it for one year from the date of manufacture. For complete warranty details, see the Terms and Conditions of Sales page in the front section of the Time Mark catalog or contact Time Mark at 1-800-862-2875.
Which pump actually starts is determined by the LEAD PUMP selector switch. The third and fourth switch (LAG and LAG-LAG) starts the second and third pumps. The final level switch (HIGH) illuminates the alarm indicator and closes the alarm bell and alarm light outputs.
As the level switches are opened (in reverse order) all operating pumps remain on until the LOW switch is opened. All pumps are then turned off and the internal alternator is triggered. On the next operating cycle the next pump depending which was on before (either 1, 2, or 3) will become the lead pump.
If the HIGH level is triggered an alarm light and alarm bell circuit are activated, plus an LED on the controller illuminates to warn of the problem.
Should this occur, an ‘Alarm Silence’ switch on the controller breaks the alarm bell contacts, but leaves the LED alarm indicator on.
When the alarm condition is corrected, an alarm reset switch returns the controller to its normal operating mode.
TROUBLESHOOTING
Problem: Remote alarm LEDs will not extinguish Causes: 1. Remote alarm inputs not jumpered closed
2. Motor circuit to close jumpers is open Solutions: 1. Install jumpers
2. Close circuit
Problem: Remote alarm LEDs come on for no apparent reason and inputs are jumpered closed.
Causes: Externally generated noise. Noise can be generated from faulty circuit breakers, contacts and motors. It can also be induced from the source being too close to the controller with little or no shielding.
Solutions: Replace faulty components; install noise suppression devices; shield wiring.
Note: This device is not a field repairable unit. Should the unit not operate properly during installation or testing, insure that all electrical, ground, and physical connections are correct. Verify that the proper voltage is applied and check all fuses. Check all motor control circuits, and insure that, if the REMOTE ALARM contacts are not used, they are jumpered. If everything is correct and the device still fails to operate, contact the factory. Should the controller fail during use, contact the factory for instructions on returning the device for repair.
MODEL 407 Liquid Level Controller
OPERATION
The Liquid Level controller can be used in either pump-down applications (with sump pumps) or in pump-up applications (to fill water tanks or reservoirs). The type of application is determined by the type of level switch used, normally-open or normally-closed.
In typical application, as shown on page 4, pumps are used to remove water from wet well when the water level activates the float switches. Activating the first switch (LOW) prepares the controller for operation. No pump is started. The second level switch (LEAD) starts the first pump.
