A. The external control module of the chilled water temperature setpoint received a
control voltage or current above or below the specified limits. (0 to 10 VDC or 4 to 10
ma).
B. The control module presented an operational failure or there is a bad contact on the
connection cable of the modules (LLID).
A. When activated, the operational reclaiming normally is interrupted by the low
pressure control. This message indicates that the low pressure control did not detect a
low pressure of 10PSI after 30 seconds after the beginning of the reclaiming.
When the reclaiming service is activated, the low pressure control did not detect a low
pressure of 10PSI after 1minute from the beginning of the reclaiming.

1A0
The current sensors detected a three-phase power loss during the operation. If the
current is less than 10%of the nominal current, the equipment will shut down in 2.64
seconds.
Remote
CA
A current level 10%higher than the maximumcurrent of operation for the equipment was
detected on one or more phases of the three-phase power supply.
Local
D9
The controller was reset after receiving a new configuration and installation of a new
version of the control software. This message is automatically deactivated and only
visualized through the log of diagnostics.
NA
B5 or B6
The equipment's suction pressure dropped below 7 psi, causing the compressor(s) to
turn off.
Local
6B6
A suction pressure below that specified for the protection systemwas detected. This
diagnostic will be automatically reset when the pressure reaches adequate values.
Local
BA or BC
The internal thermostat of the compressor identified a high temperature or the
protection against the compressor's overload detected a current level above the
protection level established.
Local
BB or BD
The internal thermostat of the compressor identified a high temperature or the
protection against the compressor's overload detected a current level above the
protection level established.
Local
