PuMP ProtectIon (systeM test)
In some circumstances not all operational stations might be hooked up. For example, if the controller
was capable of running 9 stations but there were only 7 field wires and solenoid valves available for
connection. This situation can pose a risk to a pump when the system test routine for the controller
is initiated.
The system test routine sequences through all available stations on the controller. In the above example
this would mean stations 8 through 9 would become active and would cause the pump to operate
against a closed head. This could possibly cause permanent pump, pipe and pressure vessel damage.
It is mandatory if the system test routine is going to be used, that all unused, spare stations, should
be linked together and then looped to the last working station with a valve on it.
Using the above example, the connector block should be wired as per the diagram below.
Link any unused
stations to the last
active station.
