ZENITH MX250 ATS CONTROLLER TESTED AUTOMATIC TRANSFER SWITCH MICROPROCESSOR UNIT Tested and Refurbished This one is currently set for 480VAC, standard transition with 3 phase sensing on both sources, but can be changed easily. It also has the exerciser, sync check and rotation check enabled. Similar controllers are often offered “AS IS, presumed to work, but never tested”, but why waste time on something that isn’t configured for the type of ATS you have, and may not even power up? This unit is RECONDITIONED, TESTED and GUARANTEED to operate a Zenith ZT ATS with the low voltage Relay /Transformer box. Refurbishing included adding a new exerciser calendar/clock battery. The MX250 is an excellent controller that provides the manual and automatic functions to monitor and run GE Zenith ATS models. There may be some cosmetic scratches on the case or the LCD screen. However, the controller, screen, backlight, outputs, inputs, buttons, normal and emergency voltage sensing and other circuits have been bench tested and verified to work. This MX250 controller is an exact plug-in mate to the low-voltage system-sensing and limit-switch wiring on an ATS supplied with an existing MX200 or MX250 model controller. If Source two is set for single phase sensing, this can also be directly dropped in and used instead of a MX100 or MX150 controller on an existing ATS. The difference from this v5.2 and some newer models of the MX250 is that you don't need a computer to set up this type. I can configure the unit type and voltage (if you leave a message during checkout) before shipping, and will also provide instructions on how to alter the options later yourself if desired. This auction includes: MX250 CONTROLLER, firmware v5.2. Backlit 4x20 character LCD screen. Includes new installed 10-year battery for exerciser clock/calendar. Configuration to match the system voltage and switch configuration of your existing ATS (Tell me your setup at checkout if you want it changed) Passwords to configure and calibrate voltage and other available GE Zenith Options and features. PDF Copy of operator manual for the MX250 controller. This auction does not include additional interface relays which are often mounted on a DIN rail with these controllers. These can be requested as I have quite a few available for sale. Free shipping for them if purchased at the same time. The controller includes a programmable exerciser, over- and under-voltage sensing, phase rotation sensing, and supports many options including T3/W3, Q2/Q3, A3, A4, E, L, P1, T, U, W, auxiliary indicators, and others. If the wiring for the option is present, this controller can probably support it. No additional external relays or wiring are included. This is ready to bolt into an existing ATS that has a working Relay/Transformer box, wire-harness, and mechanism. Any System: (2-wire 1-phase), (3-wire 3-phase), (4-wire 3-phase) and any voltage can be set: 120/208, 277/480, 220/380, 575VAC, 50Hz, 60Hz, and others. May be set to operates with ATS units as Open (Delay) transition, Closed Transition, or Standard Transition, and supports different styles of limit switches on the transfer mechanism. Timing of transfers is adjustable. This unit is compatible to substitute for the following GE Zenith controls models: 50P-1161RPL MX200/250 Field Replacement Kit - Factory Programmed 50P-1161SPR MX200/250 Replacement Spare Controller Kit If you get an MX250 replacement in NEW condition it will probably cost $2,500-$2,800. Also, new MX200 models are no longer sold, since the vendor wants you to use a MX250 instead. With the auction, you can keep your MX200-type ATS the same as it was. The following information is the original technical specification from GE Zenith Controls: Features and Benefits Multipurpose display: LEDs for continuous monitoring of switch position and source availability; a four-line by 20-character, backlit LCD display for settings, functions, programming and annunciation Through-the-door programming and display Simplified keypad entry - menu-driven display is designed for ease of use Built-in diagnostics with displays for ease of troubleshooting Passcode protected to limit user access Timer countdown display for ease of operation User settings unaffected by power outages Wide range of accessories and configurations available for the most demanding applications Close differential three-phase under-voltage sensing of the normal source - factory standard setting 90% pickup, 80% dropout (adjustable); under-frequency sensing of the normal source factory setting 95% pickup (adjustable) Voltage and frequency sensing of the emergency source - factory standard setting 90% pickup voltage, 95% pickup frequency (adjustable) Test switch (fast test/load/no load) to simulate normal source failure - automatically bypassed should the emergency source fail Designed for emergency and standby applications Product Scope For Zenith ATS Rated 40 to 3000 amps (2, 3 or 4 poles) Guarantee: This unit is sold guaranteed to operate as designed and sold originally by the OEM. Application of this part in an electrical power system is the sole responsibility of the buyer. Fine Print: This unit is meant for use only with compatible ATS equipment. If this part is found to fail within 14 days of delivery, full replacement is guaranteed. Buyer must pay return shipping. If the buyer damages this unit by connecting to wiring at any voltage above the rated 24V from the ATS transformers, or by other abuse of the unit, no replacement will be made. There must be an appropriate ATS relay/transformer box on the ATS for this controller to operate. Any safety and legal requirements for installation and operation of this part are the responsibility of the buyer.
