INTERFACE OPTIONS FOR GLACIATOR X-STREAM
The PLC interface connector is now fully operational on all models, without
the need to fit an extra interface PCB to the machine. This allows installers
to control the functions of the machine using active low signals from a PLC
or other automatic control system. The fog and density levels must be preset
on the display units, or alternatively, a 0-10v signal can be used at the
remote interface connector (XLR3).
Since the interface has no opto-isolators, the external control system should
use voltage free contacts or opto-isolated outputs to control the machine.
The signals are active low, and need a threshold voltage of 1.5V or less @
2mA to activate the functions. The internal circuits of the interface offer very
little overload or interference protection, meaning that any control device
POWER
should be located physically close to the machine. This will prevent
SWITCH
problems due to long cable runs etc.
The special function pin 5, is now allocated to allow the machine to be
shutdown by a remote fluid sensing system. The input is active low and has
the same electrical specification as the other inputs.
To allow the external fluid system to use a remote pump, a 'normally open'
contact is connected to pins 8 and 9.
