Entering the Type Command
N O T E
The main board is physically identical for the isocratic and the quaternary
pump. After the installation of a new mainboard the TYPE (isocratic or
quaternary) of the module is normally automatically detected. The specific
TYPE
tells the pump how to configure itself during turn on. In some cases,
especially when a defective mainboard is replaced with an older version of
mainboard, the automatic TYPE detection does not work. When the TYPE of
the exchange main board does not match the pump, a pump configuration
error will occur during pump turn on. This will cause the pump status
indicator to be red. In this case the TYPE of the module has to be entered using
the procedure described in the following sections.
You must change the TYPE of the replacement main board to agree with the
quaternary pump (G1311A). The TYPE can be entered using either the
control module or the ChemStation, see “Entering the Type Command using
the Control Module” on page 134 or “Entering the Type Command using the
ChemStation” on page 135.

case, re-enter the TYPE command correctly.
