| Model 403 |
 |
Liquid Level Controller | 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. |
| Model 404 |
 |
Liquid Level Sensor | 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. |
| Model 4042 |
 |
Liquid Level Controller | 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. |

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 407 |
 |
3-Pump Liquid Level Controller | 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. |
| Model 408 |
 |
5-level Liquid Level Sensor | 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. |
| Model 4082 |
 |
Liquid Level Controller | 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. |
| Model 409 |
 |
Liquid Level Controller | 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. |
| Model 4092 |
 |
Dual Seal Failure Detector | 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. |
| Model 4092I |
 |
Isolated Dual Seal Failure Detector | The Model 4092I Isolated Dual Seal Failure Detector is designed specifically for monitoring the shaft seals of two submersible pumps. All electrical inputs are totally isolated from each other. The probes are to be installed in the seal cavities of each of the pumps. The sensitivity is field adjustable. 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 4092I will automatically reset when the fault condition is corrected. |
| Model 4093 |
 |
Liquid Level Controller | The Model 4093 is a compact, socket mounted Liquid Level Controller that operates by monitoring the conductive liquid resistance between two probes. The unit monitors two liquid levels and responds as a pump-up or pump-down control as determined by the switch setting on the top of the unit. The green LED indicates pump operation while the potentiometer allows the user to adjust probe sensitivity. |
| Model 409D |
 |
Liquid Level Controller | The Model 409D 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, 300ms 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 11-pin octal socket (such as the Time Mark model 51X016). |
| Model 422 |
 |
Submersible Pump Controller | The Model 422 Submersible Pump Controller detects an overload or underload condition on all types of running pump motors: suction pumps, submersible pumps, etc. This Monitor detects the actual power used (voltage x current x power factor) and is more sensitive than simple current monitors. The 422 can be used with single phase pumps or, using the Model 276C current transducer, with 3-phase pumps. Matching CTs allow the Model 422 to be used with most pump motor sizes. Optional trip and restart delays are provided. |
| Model 448 |
 |
Output Relay Board | The Model 448 Output Relay Board provides electromechanical relay contacts for the Model 404 or 408 Liquid Level Sensors, allowing those models to be used as a control device. The Model 448 consists of a power supply and five relays on the surface-mounted printed circuit board. Four of the five relays are used with the Model 404. All five relays are used on the Model 408, refer to typical application. Some liquid level control applications may not require the alternating control, HOA switches, or run-time meters (see the Model 403 or Model 407 data sheets). The Model 404 and Model 408 Liquid Level Sensors uses the Model 448 to meet the needs of direct relay control applications. |
| Model 451 |
 |
Pressure Transducer | The Model 451 pressure transducer will convert 0-15psi to proportional 4-20mA signal. It can be used with any pump control system that utilizes a 4-20mA input for level control. The 451 can be mounted in a standard 8-pin octal socket for remote use. |
| Model 456-15 |
 |
Pressure Transducer | The Model 456-15 Pressure Transducer is designed specifically to meet the rigorous environments encountered in many level measurement applications. This transducer provides repeatable, precise depth measurements under the most adverse conditions. |
| Model 460D |
 |
Switch-to-Loop Converter | 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. |
| Model 662 |
 |
Pump Up Control | The Model 662 Pump Up Control, part of the 600 series line of instrumentation controls, is designed to monitor andmaintain liquid levels. A user-provided 4-20mA current loop represents the liquid level, and output connections are provided for pump control. The HIGH ADJUSTsetpoint, and the LOW ADJUST setpoint, are field adjustable. If the input falls below the low setpoint, the PUMP UP relay energizes, and remains that way until the input rises above the high setpoint. The high setpoint must always be set above the low setpoint. Top-mounted LEDs on the Model 662 show system status. The PUMP UP LED turns ON when the input falls to 10% below the low setpoint, and resets when the input rises above this level. An INPUT LOOP ERROR LED turns ON if the input is outside the 4-20mA range. A Time Mark Model 650 Loop Power Supply (or equivalent) is required to provide the 24 VDC operating voltage. |
| Model 663 |
 |
Pump Down Control | The Model 663 Pump Down Control, part of the 600 series line of instrumentation controls, is designed to monitor and maintain liquid levels. A user-provided 4-20mA current loop represents the liquid level. The HIGH ADJUST setpoint, and the LOW ADJUST setpoint, are field adjustable. If the input rises above the high setpoint, the PUMP DOWN relay energizes, and remains that way until the input falls below the low set point. Top-mounted LEDs on the Model 663 show system status. The PUMP DOWN LED turns ON when the input is above the high setpoint, and goes OFF when the input is below the low setpoint. The HIGH ALARM condition indicator turns ON if the input rises to 10% above the high setpoint. The HIGH ALARM condition then resets when the input is again less than 10% above the high setpoint. For proper operation, the high setpoint must always be set above the low setpoint. An INPUT LOOP ERROR LED turns ON if the input is outside the 4-20mA range. A Time Mark Model 650 Loop Power Supply (or equivalent) is required to provide the 24 VDC operating voltage. Also, a Time Mark Model 672-15 Pressure Transducer (or equivalent) is required to provide the input signal. |
| Model 680 |
 |
Voltage/Current Simulator | The Model 680 is a user selectable voltage or current simulator. It is useful for the setup and testing of process controllers and indicators with either a current loop or control voltage input, such as liquid level controllers and other devices. The mode of operation is displayed on the top line of the LCD. Either 4-20mA, 0-20mA, 0-10V, or 0-5V. The Model 680 can be set to any one of these four modes of operation by holding down the rotary push-button until the desired mode is displayed. The mode is saved in nonvolatile memory so that the device will power up in the mode last selected. The output signal level is displayed on the bottom line of the LCD. On power up or on changing the mode of operation, the output goes to the range minimum, i. e. 4mA, 0mA, or 0V. The Model 680 offers short circuit protection by actively sensing for any overload condition and limiting output current to 20mA. Overload at the output is indicated by OL on the top line of the LCD and occurs when the output current is 21mA or greater. Signal level is adjustable with the rotary dial in increments of 0.1mA or 0.1V, or you can depress the dial to quickly jump between the minimum and maximum values of the range. |
 |
Pump Controller | The Time Mark model 430 pump controller is a versatile and advanced liquid level/pump management system. The Model 430 was designed to control up to three pumps with a 4-20mA input. It can also be used to control 2 pumps with a 4-20mA input and backup floats or to simply control two pumps with only float inputs. Alarm inputs are provided, if necessary, and may be disabled through the menu system if not used. Alarm inputs are: SF – seal fail, OT – over temperature, CF – contact failure, and SP – spare (eg. a second seal fail). A relay output is provided for the level alarm (either high or low), depending on pump configuration; PUMP UP or PUMP DOWN. |
