Manual for SACE Tmax XT2 - XT4
Uploaded: April 20, 2026, 8:01 p.m.
The Ekip Touch Trip unit, mounted on SACE Tmax XT2-XT4 circuit breakers, offers measurement, protection, and signaling functions. It provides detailed system monitoring, protection against electrical anomalies, and communication capabilities for optimized system efficiency. The unit is designed for use by qualified and instructed personnel in electrical fields, with specific warnings and cautions for safe installation, operation, and maintenance. The manual covers overview, management operations, interface, protections, measurements, settings, and troubleshooting.
Troubleshooting and error codes
| Signal | Alarm type |
|---|---|
| Trip Test | Alert of completed trip test; press iTEST to reset the message. |
| Timing Protection (example: Timing L) | Specific timing protection |
| Pre-alarm Protection (example: Pre-alarm G) | Specific pre-alarm protection |
| Protection (Trip off) [example: S (Trip off)] | Specific protection, configured with trip disabled, alarm active |
| 21 Active | 2I protection active |
| LC1 Load / LC2 Load | Power threshold I1/ I2 exceeded and alarm active |
| Alarm Iw1 / Alarm Iw2 | Power threshold Iw1 / Iw2 exceeded and alarm active |
| Harmonic distor | Harmonic distortion protection alarm active |
| Power Factor | Power factor measurement (cos ) lower than the set threshold |
| Phase cycle | Phase sequence protection alarm active |
| Frequency | Measured frequency out of range (< 30 Hz or > 80 Hz) |
| Harmonic V over Th / I over Th / THD I over Th / THD V over Th | Single or total harmonic measurement over threshold |
| Malfunction | Possible causes | Suggestions |
|---|---|---|
| Communication problems with terminal modules | Circuit breaker in extracted position, Vaux missing or modules not inserted correctly | Insert modules, set the CB to the Engaged position, connect the Vaux |
| CB status not aligned with the CB position | Modules on the terminal board or the S751 contact missing | Check for modules on the terminal board and connect the S75/1 contact |
| The circuit breaker does not react to the open/close command from Ekip Touch | The connections or power supplies for the open/close actuators are not correct | Check connections and power supplies. |
| Display off and/or not backlit | No auxiliary power supply to Ekip Touch | Check the power supplies and the status of the Power LEDs |
| The circuit breaker is in a state that does not allow the selected command | Check the circuit breaker documentation and the cases that do not allow the command | |
| No auxiliary power supply or powers/voltages are lower than minimum switch-on values | Proper operating condition | |
| Temperature out of range | Proper operating condition |
| Malfunction | Possible causes | Suggestions |
|---|---|---|
| No power reading | Power below the minimum viewable threshold | Proper operating condition |
| Incorrect measurements (power, voltage, etc.) | Power below the minimum viewable threshold | Proper operating condition |
| Frequency setting incorrect | Set frequency | |
| Harmonic distortion and/or peak factor out of range | Proper operating condition | |
| Incorrect Rated Voltage parameter setting | Set the correct parameters | |
| Password not required | The password has been disabled or already entered during the same programming session | Correct operating condition. See the chapter on the password (page 33) |
| Password error | Password incorrect or lost | Contact ABB or view the document 1SDH001501R0001 |
| The trip test cannot be performed | The Trip coil is not connected correctly | Check the Trip coil connection and the messages on the display |
| The CB alert has not been reset | Press the reset button | |
| The bus power is greater than zero | Proper operating condition | |
| The expected trip did not occur | Trip disabled | Proper operating condition; enable trip if necessary. |
| Reaction times different from expectations | Wrong threshold/time/curve selected | Correct the parameters |
| Thermal memory enabled | Disable if not necessary | |
| Zone selectivity enabled | Disable if not necessary | |
| Neutral selection incorrect | Correct the neutral selection | |
| Quick intervention with I3 = Off | Linst intervention | Correct operating condition with high-voltage short circuit |
| High ground voltage, but trip is missing | Incorrect sensor selection | Set internal or external sensor |
| G function disabled for high voltage | Correct operating condition (see cases in the chapter describing the protection) | |
| No display of opening data | Auxiliary power supply is missing and/or battery is low. | Proper operating condition |
