Cooling System: Power Stack Adapter, Firmware Version Too Old; Cooling Liquid Temperature Has Exceeded The Fault Threshold; Cooling System: Alarm Has Occurred; Cooling System: Conductivity Has Exceeded The Alarm Threshold - Siemens Sinamics S120 Diagnostic Manual

249155 <location>Cooling system: Power Stack Adapter, firmware version too old
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: POWER ON
Cause: The firmware version in the Power Stack Adapter (PSA) is too old and does not support the liquid cooling.
Remedy: Upgrade the firmware. Check EEPROM data.
249156 <location>Cooling system: Cooling liquid temperature has exceeded the fault
threshold
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The cooling liquid intake temperature has exceeded the permanently set fault threshold.
Remedy: Check the cooling system and the ambient conditions.
249170 <location>Cooling system: Alarm has occurred
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: The cooling system signals a general alarm.
Remedy: - check the wiring between the cooling system and the input terminal (Terminal Module).
- check the external control device for the cooling system.
249171 <location>Cooling system: Conductivity has exceeded the alarm threshold
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: The conductivity of the cooling liquid has exceeded the selected alarm threshold (p0269[1]).
See also: p0261 (Cooling system, starting time 2), p0262 (Cooling system, fault conductivity delay time), p0266 (Cool-
ing system, feedback signals, signal source)
Remedy: Check the device to de-ionize the cooling liquid.
