Cat MX250 Microprocessor Controller

MX250 mikroprocessor-controlleren er standard i hele CTS-produktfamilien. MX250-serien har de samme funktioner som findes i MX150-controlleren, og tilbyder herudover udvidet programmerbarhed og mulighed for at tilpasse felter. MX250-controllerens store pålidelighed og dens mulighed for at køre uden konstant overvågning gør den ideel til brug i en lang række kritiske applikationer.

Fordele og funktioner

Features and benefits

Available to support ALL transfer modes:
–Open, Delayed and Closed Transition
User-friendly programmable engine exerciser,with or without load, at ANY interval in a one-year period
A wide variety of operating voltages available in a single controller for most domestic and international applications
Real-time display of ATS status, including active timer(s)
Multiple levels of user-defined password protection
Serial communications allowing connectivity with other ATS's, Caterpillar® Switchgear, and SCADA systems
Time-tested synchronous logic automatically measures phase angle and frequency allowing disturbance-free transfer
Unsurpassed statistical ATS/System monitoring available in real-time
Elevator pre-signal contacts automatically bypassed if the selected source fails, minimizing time an elevator is without power
Universal Motor Disconnect (UMD) sends a pre-signal, post-signal or both to any motor control center. Not bypassed in an outage,the UMD ensures safety in the event of a single phase loss
Voltage unbalance detection standard
Also includes all standard MX150 features
Back-lit/temperature compensated LCD display (includes the display of source voltage and frequency, exercise time, delay options and source condition)
Close differential 3-phase under-voltage sensing of source 1, factory standard setting 90% pickup, 80% dropout; under-frequency sensing of source 1 factory setting 95% pickup;voltage and frequency sensing of source 2,factory standard setting 90% pickup voltage,95% pickup frequency.
All factory settings are operator adjustable.
LED indicators for ATS position and source availability
Plant exerciser clock (configured for 1, 7, 14 or 28 day run selections)
Built-in time delays with count-down display
Push button to bypass time delay transfer/retransfer
Transfer/commit/no commit selection In-phase monitor
Event logging (last 16 events)
A test is standard (fast test/load/no load) to simulate source 1 failure – automatically bypassed should source 2 fail.
