See Keypad on page 3–19for details on the configuration menu list. The configuration menu is used to set all the programmable parameters outlined in Configuration Settings on page 4–29.

CTs and CPTs Sub-menu: This menu and its sub-menus are used to select Control Power Transformer (CPT), Current Transformer (CT) or Sensor Pack, and the number of turns through the CT.

Starter Type Sub-menu: This menu is used to select Motor Starter Type.

Run 1 and Run 2 Setup Sub-menus: This Run 1 menu is used to set full load current (FLA) for Run 1. It also contains sub-menus for enable/disable and configures the following optional faults: ground fault, jam, stall, current unbalance, and load loss.

Each fault is configurable not only in magnitude, but also in time delay in which that condition is allowed to exist before the LM10 trips.

The Run 2 Setup menu is laid out identically to Run 1 menu. Unless a custom motor type is selected, Run 2 setup is not necessary.

The full-load current will auto-populate if “Two-Speed” is selected. 2S1W will provide a 4:1 ratio of the FLA and 2S2W will set the FLA to a 2:1 ratio.

Only one relay at a time can be on.

Time Delays Sub-menu: The following time delays are set using this menu: Auxiliary sense 1 (contactor closed; opened detects welded contacts) Auxiliary sense 2 (contactor closed; opened detects welded contacts) Run 1 to Run 2 (delay between forward and reverse or between speeds)
