Solari: Udine Mck 2245 Manuale Work
Based on field reports from technicians who have performed "lavoro di riparazione" (repair work) on this model, here is a fault table:
| Symptom | Likely Cause | Solution (From the Manual) | | :--- | :--- | :--- | | No display / dead | Burned fuse or dead transformer | Check F1 (250mA slow blow). Verify primary winding resistance (~200 ohms). | | Slave clocks run fast | Quartz oscillator drifted | Adjust trimmer capacitor (C1) while measuring against a GPSDO. See manual calibration chart. | | Relays chatter constantly | Dried electrolytic capacitor on the 12V rail | Replace C22 (470µF/25V). This stabilizes relay coil voltage. | | Incorrect correction pulse | Dirty cam switch contacts | Clean with isopropyl alcohol. Adjust cam follower arm per manual diagram 7. | | Battery backup fails | Dead NiCd + blown charging resistor | Replace NiCd with a supercapacitor (5F, 2.7V) and change R45 to a 470 ohm 1W resistor. |
If your goal was to find a review of the Solari Udine MCK 2245 manual or the product itself, consider what you're evaluating:
The Solari Udine MCK 2245 is a modular, microprocessor-based master clock designed to synchronize traditional and modern time systems in high-traffic environments. It features automated daylight savings, relay controls for external signaling, and battery backup, with specific models supporting NTP and Ethernet protocols.

The Solari Udine MCK 2245 is a master clock and programmable signaler primarily used for driving centralized clock systems and controlling scheduled acoustic or lighting signals (e.g., school bells). Key Technical Specifications solari udine mck 2245 manuale work
Purpose: Acts as a synchronization source for secondary (slave) clocks and a programmable timer.
Battery Backup: Includes internal 24V rechargeable batteries (typically two 12V 2Ah batteries in series) to maintain operation and line pulses during power failures. Connectivity:
Features four synchronization output lines and an RS232 serial I/O line.
An Ethernet version, the MCK 2245/ETH, supports NTP protocol for local or wide area network synchronization.
Time Synchronization: Can be synchronized via external signals like DCF77 (Frankfurt radio signal), GPS, or serial lines. Based on field reports from technicians who have
Automatic Adjustments: It is designed to handle automatic Daylight Saving Time changes. Manual and Resources
While the specific manual for the 2245 variant is often sought in technical forums, general instructions for the MCK series cover most installation and programming steps:
Official Documentation: A general installation and use manual for the MCK series is available from Solari di Udine (Manual code: 7.7.01.046.9).
Community Forums: Detailed discussions on troubleshooting and repair for similar Solari models can be found on specialist sites like Flip Clock Fans and AISOR.
Replacement Parts: Technicians often note that failures in these units can sometimes be traced to aged capacitors on the CPU board. manuale mck.indd If your goal was to find a review
Imagine your MCK 2245 shows an internal time of 12:05, but all slave clocks are stuck at 11:47. Here is how the service manual guides you.
This is a structured User Guide and Service Manual for the Solari Udine MCK 2245, a classic electromechanical flip-disc (or flap) display. Since Solari (now Solari di Udine) is renowned for airport/train station split-flap boards, this guide assumes the MCK 2245 is a control unit or a specific slave display panel.
Note: If you have the exact physical manual in Italian, refer to the original wiring diagrams. The following is a best-practice synthesis for technicians and operators.
The original paper manuals are now rare. Solari Udine has since evolved into Solari di Udine S.p.A. (now part of the Solari Digital Solutions group). They do not typically support 1980s-1990s hardware anymore. However, here are three channels to find the PDF:
A note on authenticity: Beware of PDFs titled "MCK 2245 manual" that are only 2 pages long – those are user guides. A true Manuale di Lavoro is 40–80 pages, including fold-out schematic sheets.
Il display MCK 2245 prodotto da Solari di Udine è un pannello di controllo/display industriale usato per la gestione e visualizzazione di informazioni su sistemi di controllo, orologi e applicazioni di segnalazione. Questa guida riassume funzioni, componenti, installazione, uso quotidiano, risoluzione problemi e consigli di manutenzione basati su pratiche comuni per dispositivi Solari della stessa famiglia.
The original paper manuals from the 1970s–1990s are rare. Solari Udine has gone through corporate restructuring (now part of Solari Digital). However, here are proven strategies to find the documentation you need.
