What does Dixell/Copeland E0 mean?

The E0 alarm on the Dixell XC1008/XC1011/XC1015 controller indicates a high-pressure switch trip on one or both refrigerant circuits.

What does Dixell/Copeland F7 mean?

The F7 alarm on the Dixell XC1008/XC1011/XC1015 controller signals that the high-pressure switch on a refrigerant circuit has tripped too many times within a set time window.

What does Dixell/Copeland F8 mean?

The F8 alarm on the Dixell XC1008/XC1011/XC1015 controller indicates that a secondary input-driven alarm condition — governed by parameter AF15 — has activated and the working algorithm has responded by turning on a specific output or halting regulation.

What does nP mean on a Dixell controller?

nP on Dixell XR / XW controllers means "no probe" — the controller is configured to use a probe channel (Pb2, Pb3, or Pb4) but no physical probe is wired to that input. Typical scenario: a multi-probe controller (XR70CX with Pb2 evaporator probe and Pb3 condenser probe) running on a single-probe application where Pb2 / Pb3 weren't physically installed during commissioning. The fix is parameter-driven: enter Pr2 programming mode (hold SET + DOWN for 7 seconds, enter password 321), find the AP2 / AP3 / AP4 probe-allocation parameters, and either set the relevant probe channel to nu (not used / disabled) or wire and configure the missing NTC sensor. Saving with the probe disabled clears nP without affecting regulation.

What does the AL series (AL01, AL02, AL05, AL08, AL09) mean on a Dixell iChill controller?

On the Dixell IC100CX / IC120CX iChill chiller controllers, AL01–AL77 are the alarm parameter family. AL01 sets the low-pressure alarm delay in seconds (typical 30–120 s) before the LP digital input triggers a trip — prevents nuisance alarms on compressor startup transients. AL02 caps the maximum number of low-pressure events allowed in a rolling 60-minute window before the controller latches and requires manual reset. AL03 controls whether LP monitoring stays active when the compressor is off (1) or is suppressed during pump-down / standby (0). AL05 is the high-pressure alarm delay; AL08 is the thermal-protection bypass timer after compressor start; AL09 is the LP switch trip in heating mode (heat pump). Persistent AL01 / AL05 trips after delay tuning indicate a refrigerant-circuit fault — undercharge, expansion-valve restriction, dirty evaporator, or a stuck pressure switch.

What does E11, E12, E13, or E14 mean on a Dixell XWi70K controller?

E11 / E21, E12 / E22, E13 / E23 and E14 / E24 on the Dixell XWi70K serial-bus controller are the four Embraco variable-speed compressor faults (1 = circuit 1, 2 = circuit 2). E11 / E21 is overload — motor draws current above the EMB inverter trip threshold; the retry function attempts an automatic restart after a timed delay. E12 / E22 is under-speed — the compressor falls below minimum operating RPM, usually from low supply voltage or low refrigerant load. E13 / E23 is wrong-wiring — the CAB / EMB serial cable (DD190001 51) is mis-pinned or open. E14 / E24 is short-circuit — phase-to-phase or phase-to-ground fault in the compressor windings, requires a full power cycle (5-minute capacitor discharge) plus megger insulation testing before restart. HT1 / HT2 covers high-temperature shutdown of the inverter module itself.

What's the difference between Dixell XR, XW, XC, iPro / iChill, and XEV02 fault codes?

Dixell sells five distinct controller families that share the probe-fault scheme but differ in scope. XR (XR40CX, XR70CX) and XW (XW60K) are entry-level retail / walk-in refrigeration controllers — P1–P3 probe faults, HA / LA / HA2 / LA2 temperature alarms, EA / CA / dA digital-input alarms, nP / EE for missing-probe and EEPROM faults. XC (XC1008, XC1011, XC1015) compressor / condenser-rack controllers add E0 (high-pressure switch trip), F1–F16 (fan / function-code series), F7 (HP trip lock-out at AF14 count). iPro / iChill (IC100CX, IC120CX, IC200CX) chiller controllers use the AL01–AL77 alarm series for low / high pressure, thermal-overload, probe-fault (AL20–AL34 for B1–B8 probes), antifreeze, flow-switch, and water-pump faults. XWi70K serial-bus units expose E11–E14 / E21–E24 plus HT1 / HT2 for Embraco inverter-driven compressors. XEV02D digital-compressor PWM valve drivers use E01 (DLT discharge-line over-temp), E03 (block-alarm digital input), E05 (missing regulation signal). Always confirm which Dixell family is installed before consulting a code table — the same E01 means DLT alarm on XEV02D and a probe-1 fault on some XR firmware.

Quick Answer

Dixell (now Copeland after the 2024 Emerson rebrand) refrigeration controllers use P1–P3 for Pb1 / Pb2 / Pb3 probe faults, HA / LA for high / low temperature alarms, EA for external safety inputs, CA for door-open, and nP for no-probe. iChill chillers (IC100CX) add AL01–AL77; XWi70K reports E11–E14 / E21–E24 for Embraco compressor faults.
