The local operating switches in the actuator can he used for electrically operating the actuator.
1. The local operating faceplate of the control box
2. Manual/an to over-change,switch knob 2 (red): When the" switch knob is locked at the automatic position. the actuator incepts the continuous modulating signal of the control station.when the switch knob is locked at the local position The local operation can be realized by using the knob 3(blue). When it is locked at the off position, the actuator stops turning.
3. Valve open and valve close knob 3(blue); when the left switch knob 2(red) is locked at the locked at the local position, the right blue switch knob 3 is turned to the valve opened position for operating the actuator to turn for the valve opened direction or it turned to the valve closed position for operating the actuator to turn for the valve closed direction.
4. Lock pin: it can lock the switch knob 2 (red) at the manual or the automatic position. If it is necessary.it can be added a lock to protect from the un-authorized operating. When the knob is locked at the local position. The remote automatic controlling signal will not be in action.when it is turned back the automatic position.the actuator will be controlled under the remote automatic controlling signal immediately.
The wiring diagram of the integral proportional modulating model electric actuator.
The internal wiring has been done before the actuators leaves the factory,the external wiring for the user refers to fig.1.
Please turn off the power supply when the actuator is being wired.
Fig.l the external wiring diagram of the integral proportional modulating model electric actuator notes
1. The input is 4~20ma signal.
2. Input the pulse signal from terminals 35-34,36-34 (in this case, short wiring 34-39 that namely the switch K5 is at the manual position)
3. If the local operating function is not necessary, short wire teminals 7 and 8.
