15 Speed 2-Wire Operating Mode

Operation in the 15 Speed 2-Wire mode is controlled by the opto isolated inputs at J4-8 through J4-16. The opto inputs can be switches as shown in Figure 3-27 or logic signals from another device.

Switched inputs at J4-11 through J4-14 allow selection of 15 preset speeds and provide

Fault Reset as defined in Table 3-9.
