How to Set Alarm Parameters
Prerequisites
Before setting the alarm parameters, get familiar with the relationship among each parameter.
Configurations of temperature and humidity alarms and main board alarms for the air cooled devices comply with the following relationships:
- Power underfrequency alarm threshold < Power overfrequency alarm threshold
- Backup power underfrequency alarm threshold < Backup power overfrequency alarm threshold
- Supply air high temperature alarm threshold + 5°C ≤ Return air high temperature alarm threshold
- Supply air high temperature alarm threshold + 5°C ≤ Hot aisle high temperature alarm threshold
- Cold aisle high temperature alarm threshold + 5°C ≤ Hot aisle high temperature alarm threshold
- Cold aisle high temperature alarm threshold + 5°C ≤ Return air high temperature alarm threshold
- Supply air low temperature alarm threshold + 5°C ≤ Return air low temperature alarm threshold
Context
- To set an alarm threshold, follow the instructions in this section.
- The method for setting each alarm is the same. This section describes how to set Threshold of Supply air high temperature alarm to 45.
- If you need to change alarm settings, log in as the Admin user.
Be careful when configuring alarms. Only professional maintenance personnel can change alarm settings.
Procedure
- Choose on the home screen. Figure 12-21 is displayed.
- Tap Threshold following Supply air high temperature alarm.
- Set the value to 45 and tap
