HFV 8000 Generator
4 9 RF POWER
ENABLE Input Enables RF output power with an
external contact closure between
pins 4 and 9 . This pin is tied to
+15 V through a 1 k
Ω
resistor. In
order for the generator to deliver
RF output power, the conditions
below must be met in the
following order:
1. Interlocks satisfied
2. RF Power enabled and
Set point > 220 mV
3. Generator not in fault mode
(See Table 5-2 on page 5-17 )
(See Figure 4-4 on page 4-8 for an
electrical diagram.)
5 6 FORWARD/LOAD
POWER SET
POINT Analog
input 0 V to 10 V = 0 W to 8000 W
The set point circuitry uses
hysteresis. If RF on command
(pins
4 & 9 ) is enabled, the
set point signal must be greater
than 220 mV for RF to be turned
on, or less than 180 mV for it to
be turned off.
(See Figure 4-5 on page 4-8 for an
electrical diagram.)
6 RETURN Common for pins 2 , 3 , and 5 ; tied
to chassis ground.
