Fault Codes / Trane

22 codes

—

• 1 — High pressure cutout. Condensing pressure exceeded the safety limit.
• 2 — Low pressure cutout. Suction pressure too low.
• 5 — Oil failure. Inadequate oil pressure or flow in compressor.

CGAM / RTAC

• 100 — Low suction superheat — liquid floodback risk.
• 101 — High pressure limit mode active.
• 103 — High pressure cutout (HPS).
• 105 — Low pressure cutout (LPS).
• 110 — Excessive loss of communication / bus error.
• 125 — Phase loss / phase sequence wrong.
• 70 — Evaporator entering water sensor fault.
• 71 — Evaporator leaving water sensor fault.

Tracer CH530 (CGAM/CXAM)

• BAS Communication Lost — BAS was set up as installed and communication with the LCI-C was lost for 15 continuous minutes.
• Check Clock — The real time clock has detected loss of its oscillator at some time in the past (e.g. dead backup battery).
• Compressor Fault — The compressor fault switch input is open.
• Compressor Fault Lockout — Compressor fault switch input remained open for more than 35 minutes, or 5 events occurred within 210 minutes — lockout.
• High Discharge Temperature — The discharge temperature exceeded the limits for the compressor.
• High Discharge Temperature Lockout — 5 high discharge temperature diagnostics occurred over 210 minutes — lockout.
• LCI-C Software Mismatch — LCI-C Neuron software and LCI-C IPC3 software do not match.
• Low Pressure Cutout — The suction refrigerant pressure fell below the low pressure cutout trip point.
• MP: Non-Volatile Block Test Error — Main processor has determined there was an error with a block in the non-volatile memory.
• Phase Protection Fault — Phase protection module recognized a phase loss or phase reversal of the line power.
• Very Low Suction Pressure — A circuit's suction pressure dropped below 50% of the low pressure cutout setpoint — forces an entire chiller shutdown.
