A.5.3.1 Exception Status
The exception statuses are the same for the 3
compressor types. In the table below an overview
of the exception statuses is given.
A.5.5 Compressor Status
The ES-6 continuously monitors and re-calculates
which compressor will be started next and which
compressor will be stopped next (see FIG A.5.5).
To indicate which compressor will be started
next a full line is placed under the compressor
figure (e.g. compressor 2).
To indicate which compressor will be stopped
next a dashed line is placed under the compressor
figure (e.g. compressor 4)

Description Electro-pneumatic Compressor
X
No valid
compressor type
X is blinking when: • An unknown compressor type is detected
• A second variable speed drive (VSD compressor) is detected
?
No communication
? is blinking when: • For fixed speed or variable speed compres
-
sors: No reply from the connected compressor within a timeout
• For electro-pneumatic compressor: status read from the com-
pressor is not consistent or illogical
!
No answer
! is blinking when the connected compressor is not responding
(or not responding correctly) to the commands (example: no
reaction on a load command).
__
Not available
- is blinking when the compressor is stopped and is counting
down the minimum stop time. During this time the compressor
is not available for the ES 6 control algorithm.

Compressor
shutdown
* is blinking when the compressor is in shut-down condition
