Solution:
1.
Verify water supply and that the MCS unit is receiving water.
2.
Verify adequate water pressure delta.
3.
Verify that the Water Flow Loss Emergency Door Opening Temperature Threshold is not less than
5°C (41°F) above or more than 20°C (68°F) above the Server Intake Temperature Set Point.
4.
Adjust the temperature in the Server Intake Temperature Set Point or the Water Flow Loss Emergency
Door Opening Temperature Threshold fields to prevent false alarms.
IMPORTANT:
Use caution when entering temperatures in the Emergency Door Opening fields.
Setting the temperature thresholds too low might cause the MCS unit to shut down.
