描述 Description

All three switches are open and all loads are off.When the LEAD Switch closes, it energizes Load 1.As long as the LEAD Switch remains closed, Load 1 remains energized.If the LAG Switch closes, Load 2 is energized.If the LAG2 Switch closes, it energizes Load 3.Each load is turned off in sequence as the switches are opened.The entire cycle is then repeated, but with Load 2 energized first followed by Load 3 and then Load 1.NOTE: power for outputs is supplied from L connection, not through input switches (see drawing below).

应用 Application

• Voltage Tolerance: AC Operation: +10/-15% of nominal at 50/60 Hz.; DC Operation (24V only): +10/-15% of nominal.
• Load (Burden): 2 VA
• Indicator LEDs: One of the Red LEDs will be steady ON to indicate which Load will be energized first; all will flash to indicate a switch out-of-sequence error.
• Time Delay: If power is lost & returns with more than just the LEAD Switch closed, there is a fixed 10 second delay between energization of the second output (Triplex & Duplex mode) & third output (Triplex mode only) to prevent all Loads from coming on at the same time.
• Output Contacts: 3A @ 24V AC General Purpose; C300 Pilot Duty; 1/6HP @ 24VAC
• Life: Mechanical:10,000,000 operations; Full Load:100,000 operations
• Temperature: -28o to 65o C (-18o to 149o F)
• Approvals:
