4. ALARMS 4.1. BITe AND ALARMS The Built-In Test (BITe) concept comprises the monitoring of the power supplies, the power amplifiers and the optical interface. All alarms occurring can be checked via software at the Master Unit. 4.2. HANDLING OF ALARMS A message is transmitted to the Master Unit when the software acknowledges a valid alarm. A new alarm message will not be repeated if the reason for the alarm is cleared or if the alarm continues.
4.4. STATUS LED ALARMS For local supervision, a status LED on the connector flange of the remote unit gives an indication of possible reasons for alarms. This table shows possible on-site measures that could be checked before referring to the master unit alarm list. Status LED Indication Green Orange Red Status LED off Alarms Possible on-site measures No alarm Status ok Door alarm Close the door (RUs with door). Alarms not directly related to RU: External alarms Check externally connected devices.
4.5. EXTERNAL ALARM INPUTS AND OUTPUTS G1038Z0 figure 4-1 Flange connector, 5 poles G1038Z0 figure 4-2 Flange connector, 7 poles The alarm outputs (open collector output 5 V / 1 mA) are normally low. In case of an alarm they are high active (5 V). They can be used to monitor alarms with an external alarm indicator. The +28 V pin (for its location see figure 4-2 Flange connector, 7 poles) is protected by a 500 mA thermoswitch.
With the external alarm inputs it is possible to monitor the status of connected devices, e.g. a UPS, via software. All alarm inputs are normally high (5 V) without connection. The polarity (high/ low) can be set via the software at the Master Unit (for details please see according software manual). The device to be monitored must be connected so that the alarm contacts will be closed in case of an alarm (I max = 8 mA). The alarm inputs are potential-free with common ground.
