DESCRIPTION
The Model 4052 Pump-Down Controller provides total
control for duplex pumping systems. The Model 4052
monitors, controls and displays the liquid level in a tank
or reservoir. Maximum selectable depth is from 11.5 ft.
to 346 ft.
The input to the Model 4052 can be from any 2 or 3-wire
transducer with a 4-20mA output representing the
selected depth. A 24VDC regulated probe supply is
included. A Level Simulator is provided to aid in
programming these five set points; Low Alarm, Pumps
Off, Level 1, Level 2 and High Alarm.
A universal zero to 30 second On Delay can be
programmed to prevent outputs from closing due to
input fluctuations caused by turbulent conditions. An
additional 4-20mA output with zero and span controls is
provided for a chart recorder or other external device.
Four heavy-duty 10 amp, 120V contacts are provided
for pump control and alarm activation. An auto-dialer or
other emergency device can be activated with the SPDT
power loss relay. This relay is held open when power is
applied.
Pump outputs include duplex alternation as well as
hand-off-auto switches. Pump run-time can be
displayed for each pump with tenth of an hour
resolution, up to 99,999.9 hours. The Model 4052 can
be panel-mounted (11 1/8” x 4 5/8) or surface-mounted
using the optional surface-mounting kit (Model 4000).

MOUNTING & WIRING
Mount the Model 4052 Pump-Down Controller in a
panel or suitable enclosure (see Time Mark’s Model
4000 Surface Mount kit).
Referring to the terminal block decals on the unit, and
Figure 2, make the following connections:
SIGNAL INPUT
With a 3-wire 4-20mA transducer (see Time Mark
Model 450) remotely mounted, connect the +24VDC
OUT terminal to the voltage input of the transducer
(figure 3). Connect the 4-20mA IN terminals to the loop
terminals of the transducer. OBSERVE POLARITY.
figure 3.
Connect a 2-wire transducer (pressure, ultrasonic, etc.)
as shown in figure 4.
figure 4.
SIGNAL OUTPUT
The 4-20mA output is proportional to the input signal.
This allows for very accurate remote monitoring of level
changes. The factory default is for the output to track
the input; that is, a 4mA signal represents 00.0 feet, and
a 20mA signal represents 34.6 feet. However, the
output can be zeroed and spanned to a specific range,
not necessarily the same as the reading on the LED
display.
The 4-20mA OUT terminals may be connected to a
remote display or other devices. Connect these
terminals as required for your application. OBSERVE
POLARITY of the connections.
RELAY OUTPUTS
SPDT contacts are provided for PUMP 1, PUMP 2, HIALARM, LO-ALARM and POWER FAIL relays. Make
wiring connections as required.
OPERATING POWER
Connect a chassis ground to the lug marked GND and
the terminal marked G.
Connect 120VAC operating power to the terminals
marked L (line) and N (neutral).

The Model 4052 Controller has been factory tested and
calibrated. Factory settings are as follows:
HIGH ALARM
LEVEL 2 8.0 ft
LEVEL 1 6.0 ft
PUMPS OFF 4.0 ft
LOW ALARM 2.0 ft
NOTE: Both Hand-Off-Auto (H.O.A.) switches MUST
be in the OFF position before entering the SET

PROGRAMMING - SET mode (Cont’d)
The display will now show the LOW ALARM setpoint.
Change the LOW ALARM setpoint to the desired level,
using the or keys (figure 1 G,H) to the right of the
SET button. After setting the LOW ALARM setpoint,
press the SET button again. The display now shows the
PUMPS OFF setting.
Using this same procedure, set the PUMPS OFF,
LEVEL 1, LEVEL 2, and HIGH ALARM settings (in that
order).
After setting the HIGH ALARM, press the SET button, to
display the factory setting for the ON DELAY timer. Use
the or keys (figure 1 G,H) to set the ON DELAY to
the desired setting (0 to 30 seconds).
After setting the ON DELAY time period, press the SET
button again to enter the setting into memory.
Review all settings by cycling through the setpoints
before proceeding to the DISPLAY mode. Finally, press
the DISPLAY button, to enter all settings into memory.
OPERATION - DISPLAY mode
While in DISPLAY mode, the LIQUID LEVEL is shown
on the LED display. Pushing the DISPLAY button, while
in the DISPLAY mode will change the LED display from
LIQUID LEVEL to RUN TIME #1 to RUN TIME #2, and
back to LIQUID LEVEL.
If the DISPLAY button is not pushed for 60 seconds, the
LED display will automatically return to the LIQUID
LEVEL setting.
NOTE: The LOW ALARM, PUMPS OFF LEVEL 1 and
LEVEL 2 settings must move up in value from LOW
ALARM to LEVEL 2, to be properly set.
The Model 4052 will not enter the DISPLAY mode if
these settings are improper. When trying to move to the
DISPLAY mode with improper settings, the LED display
will automatically return to the SET mode. Adjust the
improper setpoint, then continue.
The HIGH ALARM setpoint can be set anywhere within
the scale.
VERIFYING SETTINGS
Before entering automatic operation, the program
setting should be reviewed and verified using the
following procedure.
While in the DISPLAY mode (with H.O.A. switched in
the OFF position), the LEVEL SIMULATOR can be
engaged.

VERIFYING SETTINGS (Cont’d)
Pump Down Controller
Push the LEVEL SIMULATOR momentary push-button
(fig. 1 W), and hold it down. The input to the external
transducer will be disabled and internal level simulator
will take its place.
Turning the potentiometer (figure 1 X ), will simulate
changes to the liquid level being monitored.
In this mode, simulated changes in liquid level will
cause the alarm relays to open and close, the liquid
level to change on the numeric display, and all LEDs to
operate (PUMP 1 and PUMP 2 LEDs will flash).
NOTES: RETURN THE SIMULATOR KNOB TO THE
MINIMUM SETTING BEFORE RELEASING THE
SIMULATOR BUTTON. The PUMP 1 and PUMP 2
relays will not energize in the LEVEL SIMULATOR
mode.
AUTOMATIC OPERATION
For fully automatic operation, set the display to monitor
the liquid level, and move the HAND-OFF-AUTO
switches to the AUTO position.
MANUAL OPERATION
To manually operate either of the pumps, push the
momentary HAND-OFF-AUTO toggle switch for the
appropriate pump down to the HAND position, and hold.

4052MC Connector
The 4052MC option replaces seal fail monitoring with motor starter
monitoring. When the 4052MC calls for a pump to run the
corresponding MC contact should close. If the MC contact closes,
the pump controller will increment the run time for that pump. If the MC contact does not close, or opens after the
pump has been started, the pump controller will not increment the run time for that motor and will flash the Run Time
light on the left side of the controller for the corresponding pump.
