A. The external control module of the chilled water temperature setpoint received a
control voltage or current aboveor 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 thebeginning of the reclaiming.

Code Diagnostic Description of Pr oblem
E5 A phase reversal was detected on the equipment's energy supply. Local
E4 The L1current sensor detected a loss of current. Local
E4 The L2 current sensor detected a loss of current. Local
E4 The L3 current sensor detected a loss of current. Local
6B6 Detecting error in the configuration in the starter module memory of the compressors. Local
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 system was detected. This
diagnostic will be automatically reset when thepressure 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
390 The controller was informed that it is linked to the Management System(BAS) and
cannot make communication with it.
Remote
398 The COM M3 communication module of the controller lost communication with the
Management System(BAS)
