EPS 45-80 High-Voltage Generator
3-2
Technical Manual P/N 9894.00.G6
The interface of the peripheral equipment with the
Epsilon
generator is done on the Controller
board and optional expansion boards (Figure 3.1).
No
tes
Most signals are site-dependent and require software configuration using the
Epsilon PC Tools
program (Chapter 4).

Epsilon
RF Generator’s principal interfacing points.
Do not connect signals to the generator when power is applied.
Typically, digital I/Os :
Are active low diode isolated
inputs
.
Are open collector
output
switches to system DC return. Active low, they get true in the
sense of the signal names when the current flows from the output terminal to the generator
DC return. Maximum current in on-state: 100 mA.
Maximum voltage in off-state: 30 V.
Must be shielded
: All signal cables connected to the generator must be shielded. We
recommend connecting the client signal shields to the appropriate chassis ground lugs on the
client section of the Controller board and/or on the optional boards (Figure 3.1, “
Signal
shield lugs
”).
