Section 2 Installation & Initial Turn-On
2.7.1 Remote/Extended Control and Status Connections
Input control lines are standard ground switching inputs. The inputs can be operated by
relay contact or transistor switching. See Figure 2-12. Grounds are provided on TB1 for
use as common.
Figure 2-12 Ground Switching for Remote Control
The status output lines on TB1 are transistor type - open collector. Figure 2-13(A)
illustrates how to interface TB1 outputs with TTL logic circuits. Figure 2-13(B)
illustrates how to interface TB1 with an external relay. A series resistor and LED can
also be used for extended status indications. Maximum external supply voltage should
not exceed +28Vdc.
