Standard Features
Electraulic™ Power Module
The key components of the Power Module include a 100% duty cycle motor, bi-directional gear pump, and Flow Matching Valves. This simple and compact design features a closed-loop, positive pressure hydraulic system which eliminates the need for active reservoirs and filters.
Display and Keypad
Simple, user-friendly push-button calibration. Displays mode of operation, current position, diagnostic warnings, and diagnostic alarms. A real-time clock provides event time and date stamping.
Pressure Gauges
Provided as standard equipment, these color-coded pressure gauges are helpful with troubleshooting should a problem arise. The gauges connect to a manifold with internal valves which isolate the gauges during normal operation ensuring high reliability.
Manual Bypass
An integral bypass is provided to equalize pressure on each side of the cylinder for use during installation and certain maintenance procedures.
Oil Level Indicator
The expansion chamber includes a large spring loaded volume indicator. Stainless steel material and an environmental seal ensure smooth operation. A “dip stick” style gauge eliminates guess work to ensure proper oil levels.
