The Solari Udine MCK 2245 is a microprocessor-controlled master clock ("orologio pilota") and signal generator designed for industrial and professional timekeeping systems. Core Functionality
As a master clock, the MCK 2245 serves as the central "brain" for a network of secondary or slave clocks. Its primary duties include:
Synchronization: It provides a central time source to drive and synchronize all connected clocks in a facility.
Automatic Adjustments: It features an internal perpetual Gregorian calendar, enabling it to automatically manage leap years and seasonal time changes (Daylight Saving Time/Solar time) without manual intervention.
Programmable Signaling: The device can act as a signal generator, often used to trigger school bells, factory shift sirens, or other time-based industrial equipment through optional programmable modules. Technical Context & Use
The MCK series is known for high reliability in professional environments where precise, synchronized time is critical, such as schools, hospitals, and transit hubs.
Installation: Detailed instructions for wiring and configuration are typically found in the MCK Installation and Use Manual .
Heritage: Manufactured by Solari di Udine , a company with a 300-year history in timekeeping and the original inventors of the iconic split-flap display system. Troubleshooting and Resources
If you are working with a legacy unit, note that newer models like the MCK 2290 have since expanded on this technology with more advanced microprocessors, though the fundamental operation of the pilot clock remains consistent. For official support or technical inquiries, the manufacturer can be reached via the Solari di Udine official site .
Manufactured by Solari di Udine S.p.A. in Italy, the MCK 2245 serves as a "pilot clock." Its primary function is to send precise electrical impulses to secondary "slave" clocks (like the famous Cifra or Dator series) to ensure synchronized time across a large facility. It also features a built-in calendar and automatic daylight savings (BST/CEST) adjustments. Technical Specifications
Manufacturer: Solari di Udine S.p.A., Via Gino Pieri 29, 33100 Udine, Italy.
Functions: Master pilot clock, signal programmer, and automatic solar/legal time switcher. Output: Typically drives 24V DC impulse clocks. Step-by-Step Programming Guide
To program the time, date, and year on a Solari master unit, follow these sequence steps (commonly used across Solari digital interfaces):
Initialize: Press the Yellow Clear key; the unit will beep once. Mastering the Solari Udine MCK 2245: The Definitive
Set Year: Press the YR key, then enter the code corresponding to the current year type (refer to the internal manual table). Set Date: Press MO to cycle to the current month. Press DM (Day of Month) to set the date. Press DW (Day of Week) to select the current weekday. Set Time: Use the H (Hours) key to reach the current hour. Use the M (Minutes) key to set the minutes.
Confirm: The clock will beep to signal it is programmed. Secure the front cover to lock in the settings. Common Use Cases & "Work" Mode
The "Work" or "Manuale" aspect of the MCK 2245 often refers to its signaling relays. These are used to:
Schedule Shifts: Program specific times for bells or sirens to trigger.
Manual Overrides: The interface allows for manual triggering of connected signals for testing or unscheduled drills.
Synchronization: If slave clocks fall out of sync, the MCK 2245 can be used to "advance" the pulses manually to catch up the secondary dials. Maintenance and Troubleshooting
Power Supply: Ensure the unit is connected to a stable 24V or 48V source as required by your specific wiring configuration.
Battery Backup: These units often contain a backup battery to retain memory during power outages; if the time resets after a flicker, the internal battery likely needs replacement.
Pulse Direction: If using with flip clocks (like the Cifra 5), ensure the polarity of the impulses matches the requirements of the slave motors.

The Solari Udine MCK 2245 is a vintage digital industrial clock, often used in railway stations and public spaces, known for its iconic Italian design and flip-display or LED technology. Finding a "work manual" or technical article for this specific model often requires looking into specialized horology and industrial design archives. Technical Overview
belongs to the "Mercure" or "Cifra" lineage of Solari Udine products. These devices were designed for high reliability and were typically part of a synchronized master-slave clock system.
Display Type: Depending on the specific sub-variant, it uses electromagnetic flip-digits or high-intensity LED segments.
Control System: Originally designed to be driven by a Master Clock (such as the Solari MCS series) using a 24V polarized pulse or a serial data protocol (RS485).
Power: Generally operates on standard AC power for the logic, but requires a signal line for time synchronization. Operating and Maintenance Highlights 23:58: It sends a "slow" pulse (alternating polarity)
Based on standard Solari Udine industrial clock protocols, a "work manual" for this unit involves the following procedures:
Manual Time Adjustment: If the clock is in "standalone" mode, time is adjusted via internal dip-switches or push-buttons located behind the front panel. In "slave" mode, time is set automatically by the master controller. Wiring: L/N: Power supply connections. Data/Pulse: Terminals for the synchronization signal.
Maintenance: For flip-digit versions, the "work" primarily involves cleaning the electromagnetic rotors and ensuring the flaps are not brittle. For LED versions (common in the MCK 2245), maintenance is focused on the power supply board and ensuring no segments have burnt out due to voltage spikes. Where to Find Full Manuals
Because these are professional industrial tools, manuals are rarely hosted on consumer sites. You can find detailed technical schematics at:
Solari di Udine Official Heritage: They maintain archives of their historical industrial line.
Museum of Information Technology: Often carries Italian industrial manuals for telecommunications and timing equipment.
Vintage Tech Forums: Sites like NewOldStock or Clock-Watch often have PDF scans shared by enthusiasts who salvage these from decommissioned train stations.

The Correction Cycle (The Genius of Solari)
Slave clocks are analog and drift over time due to mechanical resistance. At 23:58, the MCK 2245 enters a special routine:
- 23:58: It sends a "slow" pulse (alternating polarity) to advance slaves to 23:59.
- 23:59: It stops sending pulses.
- 00:00: It sends a rapid series of pulses (fast-forward) to bring all slaves precisely to 12:00 AM.
If this cycle fails, the Manuale Work guides you to check the "Correzione" relay and the optocoupler isolation circuit.
