7.3 Maintenance

Field maintenance of the TankGate is simplified by several built-in features. The

modular design of the computer control system, in conjunction with quick-disconnect

connectors, allows for on-site replacement of questionable components.

The following standard procedure can be used for repairing the TankGate:

7.3.0.1 Replacing a defective component or module

• Turn off main power.

• Open the enclosure door. Remove the case cover of the TankGate.

• Replace the defective component or module using the instruction supplied with

the spare part.

• Replace and tighten the case cover.

• Turn on power and test with PC and ViewRTU.

• Close the enclosure door.
