WaterLine Controls™ Audible Alarm
This alarm can be heard in a mechanical room or outdoors. It is very loud with a very disguised sound.
We use the relays that are already in the enclosure. It can be wired to any relay and we do that for you at the factory. We have wired it into both the high alarm and the low alarm at the same time so only one alarm is needed.
The Control Panel is still considered NEMA4X since this alarm is rated the same
WaterLine Controls™ WLC-WS3000 Specification – Set Points for: Fill ONLY for up to 5HP Pump
The Model WLC-WS3000-220-50 (This is a sensor wire length of 50 Feet) Waterline Controls Unit manufactured by System Dynamics, Inc (888-905-1892) and supplied by System Dynamics, Inc (888-905-1892) shall be supplied as a unit, including sensor with wire, controller and mounting assembly parts. A properly sized pump shall be supplied by others. The level control system shall consist of solid-state parts with non-corrosive components and is suitable for use outdoors in an industrial or residential application or indoors in a mechanical room environment. The level control system will provide automation monitoring outputs, fine control, ease of operation, ease of service and accessibility. The Control Panel shall come with a 5 Year Limited Warranty, which can be copied from: https://waterlinecontrols.com/pdfs/Lifetime_Limited_Warranty%5B1%5D.pdf and submitted.
The well water water level control system shall be automatically controlled within a range identified as “the operating range” (this range will be changed by the custom length probes being cut in the field). This condition has three outputs each which are: 1. Close a set of dry contacts for the BAS, 2 - operate a relay rated at 40AMPS for 250VAC (5HP Motor or less) and 3 - turn on an LED to indicate this sensor has tripped.
The water level control system shall be comprised of a sensor mounted inside a 3” sensor housing with wire attached that is suitable to be placed in a wet environment and installed at the water level. A separate control panel, which is to be mounted outside of the wet environment within a distance of less than 50 feet (250 feet is the maximum length of a sensor wire that can be supplied).
The 3” sensor housing shall be installed according to the drawings. The sensor head and its assembly will consist of 3 inch PVC plug, three pre-cut ¼” round stainless steel probes with thread ends. The adjustment of the sensing system shall be accomplished by adding intention rods as necessary to fit inside the operating range.
The Control Panel must be certified by an independent third party testing facility (e.g., UL or ETL) to meet Standard UL508 or equivalent for the country in which it is installed. The level control panel shall draw no more than 0.25AMPS at 110VAC or 0.125 Amps at 220VAC. All power relays shall be rated at 40Amps at 250VAC for the normally open relay contacts. All three level outputs shall have a corresponding set of normally open dry contacts rated at 0.5Amps at 60Volts to be connected to an automation system if desired.
The Control Panel shall have visual displays indicating power to the level control panel, when the control panel is actively filling. The control panel shall have a self-test button which cycles through and turns on each function in sequence for at least 10 seconds to allow for trouble-shooting as needed. This trouble-shooting feature shall operate without removing wires or disconnecting the sensing probes. This feature will be automatic and activated by pushing a button. There shall be an indicator (a Yellow LED) to indicate that this feature is operating. The Control Panel shall have an indicator which tells the operator when there is debris fouling the probes. The Control Panel shall have an automatic reset system if the well pump stays on for longer than six hours without turning off. It shall have a corresponding set of dry contacts that alerts (Closing a dry contact) the automation system.
The Control Panel shall be of modular construction such that relays that control the above features can be removed and replaced without replacing the PCB or transformer.
