PCEC Hydraulic Elevator Softstarters
up to 150 HP @ 480 VAC The PCE Hydraulic Elevator Softstarter and PCEC Panel Solution by Sprecher+Schuh are designed to simplify installation, set-up, and typical operation of motors that drive hydraulic elevators and escalators. This solid state starter solution is designed to operate 3 phase standard squirrel cage induction motors and can be connected to a 6 or 12 lead Wye-Delta (Star-Delta) or standard 3 or 9 lead motors. Through the use of LINE or INSIDE-THE-DELTA control, the solid state solution can provide ultimate control of the motor. The advantages of a solid state solution include the following:
Provides smooth motor starting
- Decreases current surges on weak electrical systems
- Reduced starting torque of the motor helps to reduce mechanical stress on system components
- Helps meet both local and regional electrical codes when reduced voltage starting is a requirement
- Eliminates voltage and current spikes associated with traditional Wye-Delta (Star-Delta) starters
- Maximizes motor life due to reduced electrical strain
- Lowers general system maintenance requirements for improved uptime
The PCEC panel solution provides a standard PCE controller and a factory coordinated fault contactor on a common mounting plate for ease of installation. The PCE controller utilizes software opti- mized for the elevator industry along with a built-in selectable Class 10, 15 and 20 overload relay and SCR bypass to control all three phases. The pre-wired control har-ness (3 ft / ~1m flying leads) is supplied to simplify wiring into current installations while the mounting plate holes are the same as many standard Wye-Delta electro- mechanical starter panels. To insure start up performance both the PCE controller and PCEC panel assembly are factory tested before shipping. The result is a quick and easy starter solution for the elevator and escalator industries.
Microprocessor control provides precision operationPCEC softstarters are under full microprocessor control, which limits starting current to the preset adjustable value. Current never exceeds the preset limit. Microprocessor control also provides finer increments of adjustment, facilitating smooth, repeatable, and accurate starting characteristics, independent of component aging and varying environmental conditions.
LED diagnostic displayAn LED display indicates operating status and fault condition (overload, over temperature, phase reversal/ phase loss, phase imbalance, shorted SCR, start fault). This enables speedy diagnosis and quick resolution of problems.
Standard fault contactorThe PCEC panel solution is equipped with a standard fault contactor which isolates one side of the motor windings from the line power in case of softstart- er fault or motor overload. Current flow is prevented by this mechanical isolation in addition to the solid state SCRs.
UL/CSA Elevator RatingsThe PCEC Softstarters are UL Listed and cUL Listed (Canadian Standards per UL 508 and CS C22.2 No. 14-95) as solid state motor controllers in File E96956. They are also UL Listed and cUL Listed per UL 508 and CAN/ CSA B44.1-96 as elevator controllers in File E3125.
