When utilizing customer control run,
connect this to the external terminals
of the customer's controller. When
controlled by a customer's controller,
"b" will be indicated on the digital
display. (Only pressure control mode is
allowed.)
Under remote operation, the operation
of the air compressor is controlled
by the input signal from the remote
switch. Under customer control run,
the operation of the air compressor is
controlled by the input signal from the
control panel of the customer.
Before the remote operation of the air
compressor can be used, the operation
switch must be activated. If the mode
of the air compressor is changed to
remote operation a change-over signal
will occur. A character "r" (Remote
mode) is displayed on the left most
position of the digital display.
When remote control is to be used, the
remote operation change-over signal
must occur before activating the remote
operation command signal.
Subject to EAR, ECCN EAR99 and related export control restrictions.
