SERIES EL-700-V ELECTRIC ACTUATORS_ 1. ^ No manual operation of the actuator while the device is energized. 2. The actuator is equipped with an over heating protection device. When the motor exceeds the temperature of 257" F (125°C), the overheat protection device will automatically switch 3. It is necessary to take additional leakage protection steps when installing the actuator and putting it into service. 4. Be sure to double check the input voltages and all other connections. 5. Do not wire two or more actuators in either series or parallel. Otherwise, it can cause movement to become...

CONTROL CIRCUIT WIRING The opening and closing operation of the actuator is regulated with the travel limit switches which open the power circuit to the motor. Two power legs and a common are needed in order to drive the actuator open and closed. Auxiliary switches are for status of valve (open/closed). 24VAC, EL-700-V and EL-700-V-M units are not equipped with the manual override push ON/OFF button. In order to operate the 24VAC and EL-700-V units with the manual override, power must be turned off to unit. All other units are equipped with the manual override push ON/OFF button which cuts...

INSTALLATION OF ACTUATOR TO VALVE (FIG. 3) 1. Rotate valve to full closed position. Ensure that the valve rotates freely with no obstruction. 2. Using the proper bolts attach the bracket to the valve - tighten loosely. 3. Place the coupling onto the stem of the valve 4. Using the manual override handle, rotate the actuator to the full closed position so that the pointer indicator points to "SHUT" (stating position of the scale). 5. Insert the output drive shaft of the actuator into the coupling. 6. Attach bracket to actuator and tighten all bolts. 7. Drive the actuator using the manual...

ADJUSTMENT OF ACTUATOR - 2 POSITION Units are calibrated at the factory to rotate 90" - if any adjustment is needed please use the following procedure. 1. Adjustment of electric limits for 2 position valves (Fig 5.) a. Full Closed position adjustment: Using the manual hand wheel or hand crank, drive the valve to the full closed position. Ensure the pointer on the dome lid is pointing red zero "shut". If not, remove lid and loosen dome indicator and re-position to red zero "shut". To adjust the closed limit switch, loosen shut position regulating shaft (S) using 2mm Allen wrench and rotate...

ADJUSTMENT OF ACTUATOR - MODULATING 1. Following procedures in section "INSTALLATION OF ACTUATOR TO VALVE" install the actuator onto the valve and ensure proper movement of unit by utiliz- ing the manual crank handle. 2. Drive the valve to the full closed position using the manual crank handle and ensure that the mechanical stops are not making contact with the housing or« screws. If there is contact, back off the mechanical limit screws until there is no contact. Loosen the lock screw on the dome indicator and position the scale to the ^J'^J full closed position "0" (SHUT POSITION) -...

ADJUSTMENT OF ACTUATOR - MODULATING does not have this functionality. • DB SWITCH - Allows for the selection of dead band on the potentiometer. Settings are 1-10 which correspond to 0,5% to • LI LAMP - Green LED is the power indicator and illuminates when power is applied to terminals "N" and "L" of the Servo- Control • L2 LAMP - Red LEO shows a malfunction of the control signal input and illuminates when the control signal is lost or weak. • L3 LAMP - Red LED shows a malfunction of the positioning circuit and illuminates when the potentiometer lead is open, • L4 LAMP - Red LED shows an...
