Excavator Timer EC 1636703 Time Relay 1636703 Description A dedicated time relay designed for excavator electrical systems. The Excavator Timer EC 1636703 provides controlled timing functions to manage start delays, shutdown sequences, and auxiliary circuit timing where a precise delay is required. Key benefits Restores proper timing functions quickly by matching part number 1636703 for direct replacement and service. Controls delay and sequencing to reduce wear on starter and hydraulic components by preventing rapid cycling. Compact, vehiclegrade design fits typical excavator control compartments for straightforward installation. Simple integration into existing wiring harnesses when replacing an original 1636703 time relay. Function and performance Provides reliable timed switching for on delay or off delay applications commonly used in excavator control systems. Maintains consistent timing behavior under normal operating conditions to support predictable machine response. Intended for use as a control module in electrical circuits that require a dedicated time delay relay. Compatibility Identified by part numbers 1636703 and 1636703 for compatibility checks during maintenance or replacement. Suitable for excavators and related heavy equipment that specify time relay 1636703 in electrical schematics or parts lists. Practical applications a failed timer to restore delayed engine shutdown or starter interlock functions and resume normal operation. Use in hydraulic control circuits to add a timed precharge or lockout interval that protects pumps and valves during sequence changes. Integrate as a delay element for lighting, alarms, or auxiliary systems so circuits engage or disengage with controlled timing. Installation and handling notes Match the part number 1636703 to the equipment parts list before installation. Handle and install according to the equipment electrical guidelines to ensure correct connections and secure mounting. If uncertain about wiring, consult the machine electrical diagram or a qualified technician. This time relay is provided as a component replacement for excavator systems that require the specified 1636703 time relay function.
