4042
The Model 4042 Liquid Level Controller monitors, displays and controls water level up to 34.6 feet, in a tank or reservoir. The Model 4042 operates from the 4-20mA input signal provided by the Time Mark Model 450 Pressure Transducer. This 4-20mA signal represents the water level to be controlled, where 4mA equals zero feet, and 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 four 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. A 4-20mA output, which tracks the 4-20mA input, is also provided. This signal output can be rescaled to different ranges of level by the user. A test control, that stimulates an input signal, is available on the front panel. The test control is useful for checking the trip set-points, and overall system operation. -
4052
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.

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.

4082
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. -
412
The 412 Automatic Reverse Controller is a current sensor designed to detect jamming of sewage grinders and to initiate the reversing of the grinder. The controller allows the selection of up to five forward/reverse cycles, and provides for an alarm output, if the number of cycles is exceeded. The current loop inputs are designed for direct connection of 10 amps at 240 VAC, or 5 amps at 480 VAC (up to 2hp motors). For higher currents, a current transformer must be used (the CT secondaries are connected to the 5 amp terminals, regardless of voltage). A manual push-button is used to simulate an over current condition and to test the relay contacts and alarm. A current level adjustment is used to optimize the trip point setting. LED indicators show the running direction of the motor and the alarm condition. -
460D
Liquid level controllers generally require a 4-20mA loop current. The loop current indicates the level of liquid in a tank or reservoir, and is usually generated by an expensive pressure transducer or ultrasonic sensor. If you already have a tank with float switches installed, the Model 460D Switch-to-Loop Converter allows you to take advantage of the latest liquid level control, without the added cost of a transducer.
The Model 460D Converter outputs a specific current value as each of the six inputs are closed. Current values are individually adjustable between 4 and 20mA for each switch input. Up to six switches can be used as inputs to all liquid level devices accepting a 4-20mA input, such as Time MarkÕs Model 4052.
