Aerator Control Module
The ProCore 648 is equipped with an Aerator Control
Module to monitor and control electrical components re•
quired for safe operation. This Module is located on the
inside of the console cover (Fig. 33).

Inputs from the start (ignition), head low limit, head high
limit, transport limit #1 proximity switch, aeration #4
proximity switch and ground follow switches are moni•
tored by the Module. The condition (open or closed) of
the ”OK to lower” circuit is also monitored by the Module.
Output to the three hydraulic solenoid valves (lower
SVL, raise SVR and quick raise SVQ) are controlled
based on the inputs received by the Module.

The Aerator Control Module does not connect to an ex•
ternal computer or hand held device, can not be re–pro-
grammed and does not record intermittent fault data.

Control module
The Aerator Control Module can be used to check op•
eration of machine switches by monitoring the LED’s of
the module. If a module LED does not illuminate (e.g. the
ground follow LED does not illuminate when the ground
follow switch is in the ON position), testing of the switch
and circuit wiring would be required.
