Optional Fan Alarm Procedure

Note: The FAN terminals wire-wrap field provides access to the Normally Open (NO), Form A fan relay contact located on the HMU-319 management unit. A temperature monitor activates this fan relay when the shelf temperature exceeds 45°C (±1°C) and deactivates the relay when the temperature drops below 35°C (±1°C). If the temperature exceeds 77°C (±1°C) a critical alarm is also generated. The critical alarm resets when the temperature drops below 40°C (±1°C).

Step

Action

1

Connect the optional fan inputs to the Alarms wire-wrap field pins 25 and 26 (see Figure 2-3).
