3.0 Closing/Opening Operation
DANGER!
Ensure that all applicable interlocks are defeated before beginning any remote switching
operation on the switchgear. Failure to do so will damage interlocks, switchgear, and/or
RSA. Please follow all applicable operation instructions and take necessary precautions as
stated in the switchgear operation manual.
1.
Ensure that the switch is fully charged as outlined in the previous section.
2.
Next, pull the spring-loaded shaft outward using the T-handle on the backside of
the shaft to disengage the tooling from the switching mechanism and bypass the
interlock. With the shaft disengaged, rotate it slightly to ensure that when it is
released it will not engage the switching mechanism.
3.
On the RSA-138 Interface Module, switch the two position switch to the setting
labeled “Open/Close Actuator.”
4.
Power on the RSO-I AR and ensure that the AR function is “ON.”
5.
To perform the applicable opening or closing operation press and hold the
“CLOSE” button to extend the linear actuator and engage the opening/closing
lever located above the shaft. The actuator will automatically retract when the
“CLOSE” button is released.
ATTENTION!
Please note that even if the desired effect is to open the switch, the “CLOSE” button must still
be pressed on the RSO-I AR. Because of this misnomer, operators must be aware of the
actions being performed on the switch.
