HFV 8000 Generator
Description
Enables RF output power with an
external contact closure between
pins 4 and 9. This pin is tied to
+15 V through a 1 kΩ 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
(See Figure 4-4 on page 4-8
electrical diagram.)
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
electrical diagram.)
Common for pins 2, 3, and 5; tied
to chassis ground.
