LP 2 PRIMEXTM 5 PC 3000 Specifications For systems with two pumps alternation if on simply swaps lead pump duty between the two pump each pump cycle If there are three pumps alternation can be either of two options In normal alternation each pump cycle the next available pump is selected as lead so that if all pumps are available then each will be lead every third time The other option is jockey pump In this type of system pump 1 is a small pump and pumps 2 and 3 are large The small pump pump 1 is always the lead pump and the other two pump alternate as lag and lag2 When either of the two large pumps are on the small one is turned off This is useful in systems where demand can be low at some times and large at others 2 4 Startup When the PC 3000 is first powered up it executes an internal self test During this test many internal functions are checked and the displays are sequenced The system is controlled by an internal microcomputer which is monitored by a watchdog timer system which will restart the system in the unlikely event that the program fails to execute properly After the self test is complete several timers are started which prevent any relay outputs from activating until all of the system inputs have had a chance to settle and all of the input filtering has resolved to their proper values 2 5 Front Panel Indicators and Controls Figure 1 is a view of the front panel of the PC 3000 It includes eight LED lamp
