Warranty Information
Warranty information is not explicitly stated in this manual excerpt.
This manual covers the operation and maintenance of SACE Tmax XT7 circuit-breakers with Ekip Touch Trip Units. It details installation, commissioning, maintenance, and troubleshooting procedures. Key sections include trip unit overview, safety requirements, accessory integration, and operating features. The manual also outlines management operations like putting into service and handling alarms and faults. It emphasizes the importance of qualified personnel for electrical operations and provides guidance on using the Ekip Touch interface for configuration, measurement, and testing. Specific chapters address various protection functions and external accessories that enhance the circuit-breaker's capabilities.
Troubleshooting and error codes
| Signal | Suggestions |
|---|---|
| Numerical alarm (e.g. 30002) | Internal error; contact ABB if this type of error occurs |
| Battery low | Change the battery (See 1SDH001000R0509 kit sheet) |
| Local bus | Unit on with auxiliary supply, Local Bus parameter enabled but connection to modules not present, incorrect or communication lost (for more than five seconds); check: connection and powering of modules in terminal box or external; that the modules connected are compatible with Ekip Touch |
| CB undefined | Check the circuit-breaker status signal contacts |
| Trip fail command (BF) | CB has failed to open and/or current still present after a TRIP command: comply with the procedure proposed in the next chapter 'Faults, causes and remedies' |
| Configuration | Protection parameter configuration error: make sure that threshold I4 and time t4 are compatible with the minimum values required for self-supply. Check: Rating plug of model compatible with Ekip Touch and CB size; If present, protection parameters do not conflict with size of current of unit details on page 42; In the absence of Vaux threshold I4 and/or I41 > 100 A; In the absence of Vaux time t4 and/or t41 > 100 ms; RC protection active and Rating Plug not RC |
| Invalid Date | Wrong date and time: set in Settings-System-Date and Settings-System-Time |
| Ekip Cl | Ekip Cl module not detected or absent, with Ekip M Touch and Open Mode configuration = Normal |
| Ekip Com Hub | Problem of Ekip Com Hub module with: certificates, connected devices, missing Com modules (RTU or with Ethernet connection), API TLS device, Hub events, parsar configuration |
| Ekip Link Bus | Fault in Ekip Link module: check for loss of connection with one or more actors (modules) connected to Link Bus |
| Ekip Sign 3T connection | Alarm for connection of one or more analog inputs to Ekip Signalling 3T module |
| Ekip Sign 3T threshold | One or more thresholds of the Ekip Signalling 3T module has/have been exceeded |
| Internal error | Internal error; contact ABB if this type of error occurs |
| SNTP error | Fault with Ekip Com modules: synchronization problem of SNTP synchronization reference module |
| Measuring Error | Measurement module parameter reading error, contact ABB |
| Ethernet disconnected | No external cable on one or more Ekip Com modules with Ethernet connection |
| IEEE1588 synch | Synchronization problem of IEEE 1588 synchronization reference module |
| MAC Address | Ekip Com module detected with incorrect / not allowed MAC address, contact ABB. |
| Ekip Installation | Installation error between HMI and Mainboard, contact ABB |
| Measuring installation | Install Measurement module (Settings-Circuit breaker-Installation-Measuring-Install) menu |
| RatingPlug Installation | Install Rating Plug (Settings-Circuit breaker-Rating Plug-Install menu) and check connection if there are further faults |
| Maintenance | Maintenance alarm: carry out maintenance and then reset the alarm via Ekip Connect (see page !da duplicazione!112) |
| Rating plug | Rating plug not present, value or size incompatible with Ekip Touch parameters |
| Zone Selectivity Diag | Error in zone selectivity connections (Hardware Selectivity) |
| S.G.R. Toroid | Check connection and state of toroid |
| Sensor L1/L2/ L3/Ne | Fault in connection of sensors to Trip unit; check status of sensors, including external Neutral, or call ABB |
| Configuration Session | TFTP server enabled and/or configuration session open on module Ekip Com IEC61850 or Ekip Hub |
| Software Not Compatible | The software versions between Mainboard and display (Ekip Touch) are not compatible with each other: To restore compatibility, please consult ABB. NOTE: modification of all parameters is inhibited via display; if present, protections L, I and Iinst are active and function with the parameters prior to the alarm (parameters of previous unit are active if display has been replaced) |
| CB status | CB state incorrect (example: current present but CB in open state) |
| Switchboard Actor communication Error | Check configuration and connection of Ekip Link module |
| TC disconnected | Disconnection of Trip coil detected, check functionality |
| Contact Wear | Make sure that the contacts/poles are in good condition. |
