It operates like this:

• When Charge Pump coil (10001) is enabled by other logic in the program, Booster Pump coil (00002) is instantly latched On.
• Whenever Charge Pump coil (10001) is turned off by other logic in the program, The T.1 timer is enabled.
• Only after the T.1 timer counts up to its maximum (in this case 50 tenths of a second = 5 secs.), coil 100 is enabled which unlatches the Booster pump coil (00002)
