Emerson Liebert iCOM Manual De Usuario

S41A Minimum Valve Pulse—Sets the minimum valve pulse % when a movement is requested. 

This parameter is adjustable from 0 - 10%. The factory default is 5%.
S41B CW Valve Delay / Power Off Time—Sets the delay time of the CW valve movement when 

power is lost. If power is lost, the valve will not move for the time entered into this parameter so the 

unit has time to come back online from a power loss. This parameter is adjustable from 0 - 60 

minutes. The factory default is 5 minutes. Sets the Power Off time; if power has been lost for the time 

entered into this parameter, the CW delay will be ignored. This parameter is adjustable from 0 - 300 

minutes. The factory default is 30 minutes.

S413 Humidification Enabled—Enables or disables humidification.
S414 Infrared Flush Rate—Shows the amount of makeup water supplied to an infrared humidifier 

as a percentage of the humidifier capacity. This value can be set from 110-500% (default is 150%). 

Higher flush rates reduce mineral deposit buildup in the humidifier pan.
S415 through S418—Not applicable to Liebert North America units.
S419 Dehum Enabled/Dehum Fan Ctrl—Selects whether the compressor and / or valve will be 

used to dehumidify when the humidity is above setpoint.
S420 Auto Restart Enabled—Restarts the unit after a power cycle when set to Yes. When this 

parameter is set to “No,” the unit will not restart (Turn On) after a power cycle.
S421 Single Unit Auto Restart—Sets a time delay for the unit to restart when the Auto Restart 

Enabled is set to YES. The delay begins once the boot process has completed. This parameter allows 

units to be staggered On to reduce the amount of simultaneous power consumption after a loss of 

power.
S422 On-Off Enabled—Sets the Liebert iCOM control to ignore the On/Off command from the 

display On/Off button when set to NO. This parameter is a local setting in the control board.
S42A Fan Shutdown Delay Timer—Sets the fan shutdown delay timer to allow the fan to continue 

to operate after the unit has been shut down. This parameter is adjustable from 0 - 999 seconds. The 

factory default is 0 seconds.
S42B Restart @ BMS Off and Disconnected—Yes allows the unit turn On if in a monitoring off 

state when a BMS Disconnect alarm occurs. Remote Off, Display Off, System Off, Alarm Off and U2U 

Standby will take priority over this feature when a disconnect occurs. No allows the unit to remain in 

a monitoring off state if a BMS disconnect occurs.
