Connector # 6 wiring (all versions except 22)
MONITOR SIGNALS
valid for all versions
On the “D” type CONN #6 there are two monitor signals, in the range 0 ÷
10Vdc (pin 2 and pin 3, ground on pin 15 and 16 respectively).
The meaning of the monitor signals can be changed only by remote inter-
face; the default setting at power-on is “Magnetron Voltage & Current” .
*: from software version 1.03 the CPU “copies” on these monitors the
incoming signals arriving from RD8400 amplifier, without making any linea
-
rization or changes; hence, the real meanings of the signal is linked to the
meaning of the RD that could be calibrated differently (i.e. the reverse signal
may be scaled 0-6000W).
