    1�1 System Description M11S-S Hydraulic Control System is a compact, modular system designed for use with Bettis spring return actuators. The system incorporates a piston type hand pump and a make-up oil reservoir necessitated by the differential volume of the hydraulic cylinder (the differential volume is due to the inboard piston rod displacement).

    Continued operation of the pump simply circulates fluid through a high pressure relief. Fully open the M11S-S by-pass control valve (30) to reverse the actuator rotation or to return to normal power operation. Actuator M11S-S Manual Operation...

    5.2.1 Shut off and exhaust the operating media from the actuators power cylinder. 5.2.2 Allow the actuator to fully stroke to its fail position by opening the M11S-S by-pass control (30) valve. 5.2.3 Remove the breather (150) from the reservoir end cap (25).
  • Page 9 5.3.10 and proceed as follows: 5.3.12 Close the M11S-S block (10) by-pass control valve (30). 5.3.13 Operate the M11S-S hand pump as described in section 4.0 to cycle actuator. 5.3.14 Replace the hydraulic cylinder inboard top o-ring plug when fluid appears. Stop operation of pump.
  • Page 10: Section 6: Maintenance

    Bettis does not recommend periodic field maintenance for the M11S-S module and pump. The only time the M11S-S module or pump should be disassembled is when either the pump or the M11S-S module fails to perform its override function. If maintenance is required and when possible the M11S-S package should be returned to the factory for maintenance.
