7.6.1.Monitor Input Level Settings

When the Monitor/Alarm Input feature is properly configured, the AFS-16 can trigger an alarm and/or perform A/B switching operations when the signal at Pin 4 (Monitor Input) on the Control Module AUX connector goes high or low. In set up this feature, you must first use the Control Card Jumper to select the non-active (non-alarm) state, and then use the Monitor/Alarm Input configuration menu to select the active/alarm state (the signal level that will trigger an alarm) as described in the Sections that follow.

Notes:

•The Monitor Input signal (Pin 4) is always measured relative to the signal at the common ground (Pin 5).

•A "Low" signal should be between Zero (0) Volts and -48 Volts and a "High" signal should be between +5 Volts and +48 Volts.
