CUB-0004: Microcomputer Duplex, Triplex, Quadplex Sequencer

4, 3 and 2 Compressor

• FOFO (First On / First Off)


• 2 Hour Sequence

• Input De-Bounce Delay

• Staggered Starting

• Manual Output Select

• Alarm Output

• Indicating LEDs

• 10 Amp,1NO

• Pick-up Delays


Initial application of supply power will cause the LEDs to flash for 2 seconds, but no loads will be energized. When #1 input switch closes, the appropriate output contact will be energized after a 5 second delay. As additional input switches close, additional output contacts will close, each with a 5 second delay. The CUB-0004 cycles outputs On and Off relative to the number of input switches that are closed based on a FOFO (First On – First Off) operation.


If multiple input switches are closed on power up, there will be a 5 second delay before the first output contact is closed. There will also be a 5 second delay before each additional output contact closes (staggered starting).


The CUB-0004 has the feature that if one output has been On continuously for more than 2 hours and another output contact is available; the CUB-0004 will switch the output closure to the one that has been Off the longest.


If all 4 input contacts and output contacts to loads are not going to be used, simply turn off the appropriate DIP switch (4, 3, 2 or 1). In addition to selecting the number of inputs and outputs for specific applications, a DIP switch may also be turned off for maintenance purposed too avoid turning On that particular output contact. The DIP switches are associated with the output contacts, not with the input switches.


The Alarm output contact will close if any one of the input switches closes out of sequence, indicating a faulty input switch. The fault will automatically clear when the out of sequence situation is corrected.


With 2 of the DIP switches turned Off, the CUB-0004 will operate in true duplex mode with the added feature of the 2 hour continuous run timer sequence.
