8 Operating modes of VS 3015 C
8.1 Manual / automatic emergency mode selection
Emergency operation of the compressor pack after a controller failure is possible using the manual / automatic
selection. The manual / automatic selection is realised at a relay level that is subordinate to the electronic
controller.
The manual / automatic switching of each compressor, gas cooler and fan is performed using the switches
S1…S10 located on the circuit board, see picture:
The following switch positions are possible:
•
A: Automatic ON (default switch position)
If any switch is in the A position, the controller registers the logical AUTOMATIC OPERATION state:
The connected equipment is controlled
as the software envisages
.
•
O: Manual OFF
If any switch is in the 0 position, the controller registers the logical MANUAL OPERATION OFF state:
The connected equipment is
not controlled
- even if the software envisages this
, e.g. pump remains off continuously!
•
I: Manual ON
If any switch is in the I position, the controller registers the logical MANUAL OPERATION ON state:
The connected equipment is
always controlled
- even if the software does not envisage this
, e.g. pump remains on continuously!
Only SIOX extension modules with manual control switch
may be connected.
SIOX extension modules
without manual control switch are not authorised
!
The manual / automatic switching is available in the same way for the basic module as well as for the
SIOX extension module.
The Manual OFF and Manual ON positions override the state desired by the software!
