Sleep mode The Sleep mode reduces the power consumption of the product. There are three types of sleep mode: ● Sleep level 1 The DC controller stops the power supply of +24V according to the +24V CONTROL signal (RMT_24V) and POWER FACTOR CORRECTION ACTIVATE signal (RMT_PFC) after a specified period of time from when a sleep command signal is sent from the formatter. The DC controller supplies +24V and the product exits sleep level 1 when a recover signal is sent from the formatter. ● Active off The DC controller stops the power supplies except for +3.3VA and +3.3VB to the formatter when an active off command signal is sent from the formatter during sleep level 1 or STBY period.
The DC controller supplies all power supplies and the product exits active off when a recover signal is sent from the formatter or the power switch is depressed for shorter than three seconds. ● Inactive off The DC controller stops the power supplies except for +3.3VA to the formatter when an inactive off command signal is sent from the formatter during sleep level 1 or STBY period. The product enters inactive off when the power switch is depressed for longer than three seconds. The DC controller supplies all power supplies and the product exits inactive off when a recover signal is sent from the formatter or the power switch is depressed for shorter than three seconds.
Power supply illumination control The DC controller changes the light of the LED (power supply illumination) for the power switch according to the power supply condition as follows: ● Lighting-up: STBY period or sleep level 1 ● Blinking: Active off ● Lighting-out: Inactive off 12 Chapter 1 Theory of operation ENWW
