MAR/DCR Series Groups 3, 9, 12, 16, 25 &40 Installation Manual
RCS ActuatorsMAR/DCR Series Groups 3, 9, 12, 16, 25 &40Installation ManualSafety First8.Manually operate the actuator from one extreme to the otherseveral times.In the maintenance and operation of mechanical equipment, SAFETY isthe basic factor which must be considered at all times. Through theuse of the proper clothes, tools and methods of handling, seriousaccidents causing injury to you or your fellow worker can be prevented.To Manually Operate:Models MA8, MAR8:Throughout this manual are listed a number of safety precautions.Study them carefully and follow them; also insist upon those workingfor you do the same. Remember, an accident is usually caused bysomeone’s carelessness, neglect or oversight.CAUTION Manual operation is accomplished by use of an open-endwrench on the hex stock-coupling adapter. Direction of rotation and or position can be checked byindicator located on output shaft. Avoid turning beyond normal open/close travel.Models MAR10, 50 & 90:To prevent ignition of hazardous atmospheres, do notremove actuator cover while curcuits are live. Pull the black declutching knob (A) all the way up and hold.Gently rock shaft back and forth with wrench to disengage, androtate to desired position as indicated by the arrows. Actuator will automatically re-engage when “knob” is releasedand electrical power is applied.Avoid turning beyond normal open/close travel.Installation1.Operate valve manually before installing actuator and place intoopen position.2.If valve is equipped with mechanical position stops they shouldbe removed, but care should be taken not to damage or removenecessary parts from the valve. When actuator is supplied separately from valve, actuator willbe shipped in valve open position and care should be taken tomaintain proper alignment between the actuator and valveshafts. If actuator and valve shafts are not in correct alignmentrepeat operation number one (1) with correction as required. Depress and rotate handwheel slowly until detent is felt toengage. Turn handwheel in desired direction (note markings on wheeland check position by indicator located on output shaft). Avoid turning beyond normal open/close travel. When handwheel is returned to raised position, electricaloperation is restored (see manual cut-off switch).3.Models MAR100, 120, 160, 250, 800, 1600 & 4000:Direction of rotation is defined as the direction the actuatoroutput shaft rotates (CW or CCW) as viewed from above the topof the actuator.4.Mount the actuator to the valve. The actuator is usually mountedparallel to the run of the pipe. Tighten all bolts and nuts evenly,taking care to center the actuator on the valve stem. It is often agood idea to manually cycle the actuator while the mountingbolts are somewhat loose. This will allow the unit to centeritself.5.Loosen socket set screw and remove the manual declutchingknob (Models MAR/DCR10, 50 & 90 only).6.Remove the hex bolts located around the enclosure of theactuator.7.Wire per diagram, or if actuator is of special design, wiringdiagram is included with unit. Wiring diagram is drawn with theactuator in the open position. Use #18AWG stranded wire orbetter, for field hook-up.Manual cut-off switch:When handwheel is depressed for manual operation, an integralcut-off switch prevents injury due to unexpected restoration ofelectrical power and is automatically reset when handwheel isreturned to raised position.
