4000

4000

4000-Series, Liquid-Level-Controls

The Model 4000 Surface-Mounting Kit makes it easy to install the following Time Mark Liquid Level Controllers: Models 403, 404, 4042, 4052, 4062 and 408. This 20 gauge steel enclosure features a removable top panel for easy access to connections. The mounting kit comes complete with everything you need, including steel support brackets. Designed for applications that require surface-mounting of our Liquid Level Controls.


403

403

403-Series, Liquid-Level-Controls

The 403 Liquid Level Controller provides central control of duplex pumping systems. The Model 403 includes pump alternating, visual run-time meters, hand-off-auto control and alarm outputs. Four level-sense inputs interface with float switches, pressure switches, or other level sensing devices which can provide a contact closure.


404-115V

404-115V

404-Series, Liquid-Level-Controls

The Model 404 Liquid Level Sensor operates in conjunction with a Model 403 Controller for bubbler-type duplex pumping systems. The 404 contains an air pressure-to-voltage transducer and requires only a small air compressor capable of 15 psi to operate the system down to approximately 35 feet. The Model 404s four outputs are designed to replace the float switch inputs to a Model 403, or to be used with a Model 448 output Relay Board. A 4-20mA signal output provides for other control applications. A 3-digit LED display continuously shows the liquid level to a tenth of a foot when the Display Control switch is in the Liquid Level position. Other settings of the switch allow setting of the liquid level trip points. LED indicators illuminate as the levels are exceeded. A test control allows the trip settings to be checked without actually raising or lower the liquid level.


4052

4052

4052-Series, Liquid-Level-Controls

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, up to a depth of 34.6 feet. The input to the Model 4052 can be from any 2 or 3-wire transducer with a 4-20mA output that represents 0 to 34.6 feet. 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. Communications capable via RS-485/Modbus. 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 in. x 4 5/8 in.), same as Time Mark Models 403, 404 and 4042, or surface-mounted using the optional surface-mounting kit, Model 4000. Model 4052BT offers Bluetooth communications in addition to RS-485/Modbus.


4062

4062

4062-Series, Liquid-Level-Controls

The Model 4062 Pump-Up Controller provides total control for duplex pumping systems. The Model 4062 monitors, controls and displays the liquid level in a tank or reservoir, up to a depth of 34.6 feet. The input to the Model 4062 can be from any 2 or 3-wire transducer with a 4-20mA output that represents 0 to 34.6 feet. A 24VDC regulated probe supply is included. A Level Simulator is provided to aid in programming these five set points; Low Alarm, Level 2, Level 1, Pumps Off 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. Communications capable via RS-485/Modbus. 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 4062 can be panel-mounted (11 1/8 x 4 5/8), same as Time Mark Models 403, 404, 4042 and 4052, or surface-mounted using the optional surface-mounting kit, Model 4000. Model 4062BT offers Bluetooth communications in addition to RS-485/Modbus.


407

407

407-Series, Liquid-Level-Controls

The Model 407 3-Pump Liquid Level Controller provides central operating control of triplex pumping systems. The solid-state electronic controller provides alternating of load pumps, low level cutoff and high level alarm outputs. Runtime meters provide instant visual data on total running time of each pump motor. LED indicators show ON/OFF status of each pump. The 407 has five level-sense inputs which can be activated by float switches or other level sensing devices which provide a switch closure.


408-115

408-115

408-Series, Liquid-Level-Controls

The Model 408 is a 5-level liquid level sensor designed for use with bubbler-type systems. The 408 contains an internal air pressure transducer; the user must provide a small air compressor capable of supplying a maximum of 15 psi. This operates the system to a liquid depth of 34.6 feet. The output of the 408 connects to the inputs of the Model 407 3-Pump Liquid Level Controller (replacing the float switches) or to a Model 448 Output Relay Board. A 4-20mA signal output is provided as an input to process controllers or for other control applications. A 3-digit LED display continuously shows the liquid depth to 0.1 foot when the display control switch is in the Liquid Level position. Other switch positions allow setting of the corresponding trip level points. The trip points are set using coarse and fine adjustment pots, and are shown on the LED display. Each trip level has an LED indictor which illuminates as the solid-state output makes. A test feature allows the trip settings to be checked without actually changing the liquid level.


4082

4082

4082-Series, Liquid-Level-Controls

The Model 4082 Liquid Level Controller monitors, displays and controls water level up to 34.6 feet in a tank or reservoir. The Model 4082 operates from the 4-20mA input signal provided by either the Time Mark Model 450 or Model 456-15 Pressure Transducer. This 4-20mA signal represents the water level to be controlled, where 4mA equals zero feet, and the 20mA equals 34.6 feet. A liquid crystal display (LCD) is provided to show the water level during normal operations, and the set-point values during calibration. There are eight user-adjustable trip set-points. As the water level rises above each trip point setting, the front panel LED for that level illuminates, and the corresponding output relay energizes. Two 4-20mA outputs, which track the 4-20mA input, are also provided. These signal outputs can be rescaled to different ranges of level by the user. A test control, that simulates an input signal, is available on the front panel. The test control is useful for checking the trip set-points, and overall system operation.


409-120

409-120

409-Series, Liquid-Level-Controls

The Model 409 is a compact, socket-mount device for level control of conductive liquids. The internal relay is energized when operating power is applied. When the liquid level reaches the probe, the relay de-energizes. When the level drops below the probe, the relay will reset. A fixed, two-second time delay prevents oscillation due to wave action. Probe cables may be shielded or unshielded. If the liquid container is made of a non-conductive material, a common electrode is required. Other features include an LED indicator to show the output relay status and an adjustable sensitivity setting.

Requires a standard 8-pin octal socket. (socket number 51X00120-01)


4092-120

4092-120

4092-Series, Liquid-Level-Controls

The Model 4092 Dual Seal Failure Detector is designed specifically for monitoring the shaft seals of two submersible pumps. The probes are installed in the seal cavities of each of the pumps. When a seal begins to leak, contaminating fluid enters the seal cavity, lowering the resistance between the probe and the common connection. If the resistance drops below the sensitivity set-point, the corresponding relay and the LED indicator are activated. The Model 4092 will automatically reset when the fault condition is corrected. The sensitivity is field adjustable.
