3-4.6 METERED VALUE (ME)

The phase, neutral and ground currents are displayed in the Metered Values menu, as well as Total Energy, Forward Energy, Reverse Energy, Power, Peak Demand, Power factor, %THD of each phase, and Harmonic Content of each phase.

3-4.7 TEST MODE (TM)

Simulations of either a long delay, short delay, or instantaneous fault condition can be performed by using Test Mode. This can be done by first reading

the setpoints and noting their adjustment. The trip mode menu item can then be selected and a current above the noted settings can be entered. A trip or no trip test can be performed. A test in progress may be terminated if the currents through the breaker under test are above 40% of the rating plug value. See section 3-9.

3-4.8 SETPOINTS MENU (SE)

The trip unit can be adjusted for various time-current characteristic curves. This is done within the Setpoints Menu. See section 3-7, and Figure 3-1.

Notice: 1) Short Delay and Instantaneous Action can not be turned off at the same time.

2)When long delay is set to I4t, the short delay slope must be set to Flat.

3-4.9 PASSWORD (PA)

settings or use certain features. To change the baud rate or trip unit address, setpoints, run test mode, or download copied setpoints, a correct password must be used. The OPTIMizer’s factory default setting is 1000. See section 3-5for additional details.

3-4.10 TRIP EVENT COUNT (TC)

The trip unit records the number of times that the trip unit has initiated a trip. This is displayed when the Trip Event Count is selected.

3-4.11 CAUSE OF TRIP (CT)

The OPTIMizer can display the cause of trip, similar to the cause of trip LEDs of the trip unit, but in some cases with more specific information. This information is available as long as the trip unit Reset pushbutton has not been pressed after a trip condition. For example, a non-compliant rating plug may cause an instantaneous trip to occur which will light the Instantaneous LED of the trip unit. However, the OPTIMizer in this case would display that the instantaneous trip is a result of a Bad Plug.
