ACCESSORIES
−
AER485P1: Through this accessory, it
is possible to connect the unit with
BMS supervision systems with electrical
standard RS 485 and MODBUS type
protocol
NOTE: disclosure must be provided for
compressor No. 1 .
− PGD1:
In addition to the control
terminal on board the machine
itself, NXW machines can also be
equiped with an external PGD1
remote control terminal. PGD1
remote terminals provide the same
functions as the on-board terminals
(keyboard controls and display).
− PGD1 terminals can be installed at
distances of up to 1 km from the
machine (up to 50 meters with tele-
phone cable AWG24, for distances
of over 50 metres ensure that the
2nd extension card is powered by a
voltage between 21 and 30 V dc.
5.2. ELECTRICAL ACCESSORIES
− RIF: Current phase advancer. Parallel
connection with the motor makes the
reduction of input current possible.
It can only be installed when the
machine is being made and must
therefore be specified when the
order is placed.
− DRE: It permits the reduction of the
starting current needed by the
machine in the start up phase. This
accessory can only be applied in the
factory.
