An incorrect switch setting (e.g., TEST/BOOT) may cause the pump to turn into a basic
N O T E
mode (yellow or red flashing status light). In such a case turn off the pump, re-set the
address switches, and turn on the pump again.

Entering the Type Command
The main board is physically identical for the isocratic and the quaternary pump. After the
N O T E
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 G1323B, or the Instant Pilot G4208A, or the ChemStation.
