13InRow RC Operation and Maintenance Manual
General Configuration
The configuration options are set during the commissioning of the cooling units in the cooling group.
NOTE: All changes to settings must be performed by qualified personnel.
Cooling unit configuration
Path: Main > Configure Unit > General
Capacity: Set the cooling capacity of the cooling unit:
– Auto: The cooling unit automatically controls its output under normal (default) conditions.
– Max: The cooling unit runs at full capacity.
NOTE: Normal checks for cooling failures are disabled in the Max mode.
Start-up Dly: Enter a value for the delay. The start-up delay begins when the cooling unit is started and
initialized. The cooling unit cannot begin operation until this delay expires. Use the start-up delay to restart
equipment sequentially in your room after a scheduled downtime or a power outage.
Idle on Fail: When set to Yes, the cooling unit will enter idle mode if the cooling unit is unable to supply
conditioned air. Set to No to disable the cooling unit from entering idle mode if a Cooling Failure is detected.
Idle On Leak: When set to Yes, the cooling unit will enter idle mode if a Water Detection Fault activates. Set to
No to disable the cooling unit from entering idle mode if a leak is detected.
NOTE: The leak sensor (part number AP9325) is optional.
NOTE: There are three alarms that will cause the cooling unit to enter idle mode:
• Water Detection Fault (when Idle On Leak is set to Yes)
• Condensate Pan Full
• Cooling Failure (when Idle On Fail is set to Yes)
See “Alarm messages and suggested actions” on page 27 for more information on alarms.
Bypass Vlve (Bypass Valve): Select the setting that matches the physical status of the bypass valve (open or
closed).
Fluid Cal: Causes the input valve to stay fully open to facilitate adjusting water flow through multiple cooling
units.
Role Override: Set to ON, forces the cooling unit to be the Primary cooling unit in the group. Set to Auto,
allows the system to choose the role of the cooling unit. Choose ON if you have Runtime Balancing enabled
and you DO NOT want a particular unit in the group to become a backup unit. See “Cooling Group
Configuration” on page 15 for more information.
