when the master controller isn’t able to cycle
through its operation.
Make sure all electrical connections are
appropriately shielded so the master controller is
not disrupted by noise.

the request of the master controller.
The master controller will try to recover from
the fault. If unsuccessful, replace the pressure
module.

interface. This will only appear when the
master controller is used in conjunction with
a slave board.
Make sure the control cable used in the daisy
chain interface is properly shielded from noise.

in module configuration or a fault in one of
the modules.
Reinstall all modules in accordance with the
instructions in the factory IOM.
Err 5
If the fault described in “Err 4” is not
corrected, the master controller will
reconfigure the modules that are responding
properly and operate at a degraded
condition.
