5.3 Remote keyboard connection – Only for XC660D -7x0xx- or
XC660D -7x2xx-
**** ONLY FOR THE MODELS WITH 90-260Vac POWER SUPPLY
IDENTIFIED BY THE FOLLOWING PART NUMBERS: XC660D -7x0xx- or
XC660D -7x2xx-****
The VC660, remote keyboard for XC600D series, can be connected only to
the models with the above part numbers.
Use shielded 2 wires cable AWG 20, max allowed distance between
controller and keyboard: 30m.
Respect the polarity indications: as for the following table
XC660D -7x0xx- or XC660D -7x2xx-
VC660
Terminal:29 (+)
Terminal: 1 (+)
Terminal:30 (-)
Terminal: 3 (-)
5.4 Probes connection
5.4.1 General warnings
Pressure probe (4 - 20mAor ratiometric): respect the polarity. If using terminal ends be sure
there are no bear parts which could cause short circuiting or introduce noise disturbance at high
frequencies. To minimize the induced disturbances use shielded cables with the shield connected
to earth.
Temperature probe: it is recommended to place the temperature probe away from direct air
streams to correctly measure the temperature.
5.4.2 Probe wirings
Low voltage side : Keep the cables away from the power cables. Use shielded cable to lengthen the
cables.
NOTE1: The PIN 38 is the common line for the temperature probes
NOTE2: The PIN 37 gives a 12Vdc supply for the 4-20mA pressure transducers
PP07 PP11, PP30, PP50 4÷20mA pressure
transducers respect the polarity.
