Pump Configuration

Assign Pump to a PCU
Each pump you defined in submenu 1 must be assigned to a pump control unit (PCU). Pumps
are assigned to slots on the PCU. Each PCU has one or more slots. The number of slots
available depends on the type of PCU. There can be up to 32 PCUs in the system, the same as
the number of pumps.
Use submenu 2 of the pump configuration program to assign pumps to a PCU. The submenu
shows the PCU number and type and the slots in use. You can add a new PCU, modify the
pump numbers assigned to an existing one, or delete a PCU. It is not necessary to delete a PCU
that is not in use.
Auto-configure PCU
The auto-configure option (which you can activate by pressing C at submenu 2) assigns pumps
to PCUs automatically. Any existing PCUs will be deleted. Each pump will be assigned to a
PCU, but all slots in PCUs may not be filled if pump types are mixed.
Auto-configure starts with the first pump from the list of existing pumps (set up in submenu 1)
and adds a PCU of the correct type. If the second pump is of the same type and the PCU has
another slot available, the pump will be assigned to that slot. If the second pump is of the same
type, but no slot is available on the first PCU, a second PCU will be added. If the second pump
is of a different type, a second PCU of the corresponding type will be added. This is repeated
for each succeeding pump in turn, so that at least one PCU is created for each sequence of
similar pumps.
Auto-configure adds a new PCU at each point in the list where the pump type changes. It does
not check to see if there is an existing PCU of that type with an empty slot. If auto-configure
leaves too many empty slots of the same type, you may wish to use the delete and modify
options on submenu 2 after running auto-configure.
Tokheim Pumps
For Tokheim pumps only, the poll address set at the pump will probably not be the same as the
PCU number assigned to it in submenu 2.
Each Tokheim model 98 pump controller can handle up to eight 162 pumps. The poll address
of the first 162 on a Tokheim 98 pump controller is always 1 or 9. The poll address of the
second 162 pump is always 2 or 10, and so on, regardless of the PCU numbers. If you need to
skip a Tokheim 162 poll address, you should add a Tokheim PCU with no pumps assigned to
it as a placeholder in that position.
