Damper System Operation 52 Decommission
10. Isolate the system from electrical power.
When the system electronics, control software, and the system PC are
powered down, turn off the system’s main electrical supply and disconnect
all cables.
Residual hydraulic pressure can produce a high pressure spray.
You could be cut by this spray or hydraulic fluid could be forced into your
skin.
Do not start this procedure unless the system has been isolated from hydraulic
pressure for at least 20 minutes. Always be cautious when you loosen any
hydraulic connection or remove bolts or screws from any hydraulic component.
Always allow fluid pressure to dissipate slowly until completely vented before
continuing to loosen. Always wear gloves and appropriate eye protection.
11. Remove all accessible hydraulic hoses.
The system does not have hydraulic reservoirs that must be drained.
However, each hose and hard line will potentially have trapped oil in it.
When removing the hydraulic components, ensure that you have drain pans
and towels available that are sufficient to handle the drain volume of the
item you are disconnecting. Use safe practices when removing hydraulic
components and allow any trapped or latent pressure to dissipate safely
through a loosened connection before removing the component. Cap each
hose, port, and hardline component.
12. Dispose of all hydraulic fluid in accordance with all local codes regarding
hazardous materials handling and disposal.
13. Disconnect all cables from the controller.
14. There are two configurations for the controller: contained in an upright
console (perform step A) or floorstanding (perform step B).
A. Upright consoles are lifted by an overhead lifting devise using supplied
lift rings. If necessary, install lift rings in the threaded bores at the top
of the control cabinet. If not already installed, the lift rings are typically
stored inside the cabinet or in receptacles at the rear of the cabinet. Rig
and lift the cabinet and set aside.
B. Floorstanding controllers can be lifted onto a suitable cart and moved
to a desired location.
