SymCom 455-575 MotorSaver
455-575
The New Model 455s are now Microcontroller Based equipped* with an infrared LED to communicate with the hand-held diagnostic tool, the Informer-MS, to display MotorSaver® data to assist in monitoring and troubleshooting the system. Motor run hours, displayed by the Informer-MS can now be reset on the Model 455**. Protects 3-Phase motors from: Contact failure Loss of any phase (single-phasing) on the load or line side Low voltage High voltage voltage unbalance phase reversal rapid cycling The status of the Model 455 can be easily identified by the four LEDs on the front of the device: Run, Undervoltage, Overvoltage, and Phasing Fault or by using the Informer-MS, which, in addition to present status, will display live voltages, last 20 faults, last 32 motor starts, and motor run hours**. The 455's universal range from 190-480VAC 50/60Hz provides the versatility needed to handle global applications. Four adjustments pots provide versatility for a variety of applications. Both load and line-side monitoring provides contactor protection. Diagnostic LEDs indicate trip status and provide simple troubleshooting. Microcontroller-based circuitry provides better accuracy and higher reliability than analog designs. Single-phase conditions are detected regardless of regenerated voltages. Transient protection meets IEEE and IEC standards and permits operation under tough conditions. Manual, 2-300 second variable restart delay 2-8% variable voltage unbalance 2-30 second variable trip delay Surface mount Finger-safe terminals UL and CcUL listed 5-year warranty Made in USA The Model 455 (190-480VAC) and the 455-575 (475-600VAC) are equipped with one SPDT 480VA @ 240VAC output relay. *Effective March 2006 **To reset the motor run hours in the Model 455: 1) record settings 2) remove power 3) turn all setpoint knobs to the minimum setting 4) apply power momentarily 5) remove power again 6) adjust knobs back to the desired settings 6) reapply power.
