NICAL 48VAC DIN Rail Power
Product Information
This product is a timer designed for various applications. It allows the user to program the ON and OFF cycle times within a range of 10 milliseconds to 99 hours. The programmed time is indicated by an LED display. The timer offers different functions, including starting with the ON time and then the OFF time, starting with the OFF time and then the ON time, single shot mode with switching OFF indefinitely after the ON time, single shot mode with switching ON indefinitely after the OFF time, and more. The product comes with safety and warning instructions that must be followed to ensure safe and proper usage. Non-compliance with the instructions or improper handling of the product can void the warranty and may result in damages for which the manufacturer will not be held liable. It is important to observe valid safety rules during installation and usage, prevent unintentional operation or damage, and always depressurize the compressed air system before working on it. The timer should be checked at least once a year, and serviceable parts should be replaced when necessary. The strainer should be periodically cleaned to avoid possible blocking caused by rust and debris. The valve function should also be checked periodically, and a purging sound must be heard.
