Refer to Safety Precautions for All Timers. When selecting a control output, use the H3Y-2 for switching ON and OFF the power and the H3Y-4 for switching ON and OFF the minute load. The operating voltage will increase when using the H3Y in any place where the ambient temperature is more than 50°C. Supply 90% to 110% of the rated voltages (at 12 VDC: 95% to 110%) when operating at 45°C or higher. Do not leave the H3Y in time-up condition for a long period of time (for example, more than one month in any place where the ambient temperature is high), otherwise the internal parts (aluminum electrolytic capacitor) may become damaged. Therefore, the use of the H3Y with a relay as shown in the following circuit diagram is recommended to extend the service life of the H3Y.
Do not connect the H3Y as shown in the following circuit diagram on the right hand side, otherwise the H3Y’s internal contacts different from each other in polarity may become short-circuited.
Use the following safety circuit when building a self-holding or selfresetting circuit with the H3Y and an auxiliary relay, such as an MY
