Thresholds page
Sensor Values. View the temperature values reported by these sensors:
• Rack Inlet Temperature—The temperature of air entering the enclosure on which the Rack Inlet
Temperature Sensor is installed.
• Supply Air Temperature—The temperature of air leaving the unit.
• Return Air Temperature—The temperature of air entering the unit.
Thresholds. Configure the temperature thresholds:
• Rack Inlet High Temperature—Specify the high-temperature threshold. If air entering the
enclosure is above this temperature, the unit generates an alarm.
• Supply Air High Temperature—Specify the high temperature threshold for air leaving the unit.
If the temperature exceeds this threshold, the unit generates an alarm.
• Return Air High Temperature—Specify the high temperature threshold for air entering the unit.
If the temperature exceeds this threshold, the unit generates an alarm.
Configuration page
Configure the startup delay, define the normal state of input contacts and output relays that affect the
behavior of the unit, define how the unit will respond when an alarm condition is detected, and specify
the units of measure the unit will use.
• Startup Delay—Set the delay that begins when power is applied and ends when the unit starts.
Valid values are 0 to 999 seconds.
• Idle on Leak Detect—Idle the unit when a leak is detected. By default, this feature is not
activated.
• Input Normal State—Define the normal state of the input, open or closed. The unit changes its
operating mode to Standby when the input is not in its normal state.
• Output Normal State—Define the normal state of the output, open or closed. When one or more
alarms are present on the output source, the output will be set to its abnormal state.
• Output Source—Define the type of alarm that will change the state of the output.
• OHE Input Normal State—Define the normal state of the Outside Heat Exchanger (OHE), open
or closed. An alarm is generated if the current state differs from the configured normal state.
• Unit Role Override—When set to Automatic (the default setting), the system defines whether
this unit is used as a primary or redundant unit. When set to Forced On, the unit is always a
primary unit.
• Idle on Cool Fail—Idle the unit when the supply temperature exceeds 90°F (32.2°C) for a
maximum of five minutes. The time limit decreases as the temperature rises. By default, this
feature is enabled.
• Display Units—Define whether this interface will display Metric or US units of measure
