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 3-28 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 3-10.
