Description

Description The Servo Electronic Valve (SEV) is controlled by closed loop digital electronics, providing consistent acceleration and deceleration of hydraulic elevators largely independent of load and oil temperature. An electronic card regulates the performance of the car via variable-flow solenoid valves. The elevator operation can be monitored, recorded and adjusted by a laptop computer either on site or remotely through the modem connection. Additional intermediate speeds for maintenance runs can also be programmed. Up directionUp to 1.0 m/s (200 fpm). 1 full speed, 1 inspection speed and 1 levelling speed. All transitions are smooth programmable. For up stop the motor must run approx. 1 sec. longer through a time relay. Down Up to 1.0 m/s (200 fpm). 1 full speed, 1 inspection speed and 1 levelling speed. All transitions are smooth programmable.
