3.7.3 Supervise for short
When supervised for short, the active state in the Configurator is Open. A single
47 kΩ resistor is required for short supervision as shown below.
Note:
3.7.4 Supervised for open and short
When supervised for both open and short, the active state cannot be open,
therefore the active state in the Configurator is Close.
Two 22 kΩ resistors are required for supervision.
