DC(M)24-(44/88) Series - Installation, Operation & Maintenance Manual Continued
Warning - These actuators are designed for use only in conjunction with operating controls. Where an operating control failure would result in personal injury
and/or loss of property, it is the responsibility of the installer to add safety devices or alarm systems that protect against, and/or warn of, control failure.
To avoid excessive wear or drive time on the motor, use a controller and/or software that provides a time-out function to remove the signal at the end
of rotation (stall).
Disclaimer - The performance specifications are nominal and conform to acceptable industry standards. For application at conditions beyond these
specifications, consult the nearest Bray oce. Bray controls shall not be liable for damages resulting from misapplication or misuse of its products.
