3.8.7 CLI and Discriminator PC
Board
Jumper JU2 provides alternate contact status (NO
or NC) for margin relay.
Jumper JU3 should be left untouched.
3.8.8 Receiver Logic PC Board
The Receiver Logic Module (style number CF20-
RXLMN-00X) has no jumpers on its PC board.
Instead, it provides three banks of DIP switches to
control its logic functions. Each board also
includes a pre-programmed, plug-in EPLD chip
for one of the following types of application:
• 2-Frequency Directional Comparison
• 3-Frequency Directional Comparison
• 2-Frequency Phase Comparison
For complete information and instructions on
setting the DIP switches, please refer to “Setting
the DIP Switches for Your Application” in Chapter
16. For a diagrammed overview of the possible
DIP switch settings and other signal flow infor-
mation for each application, please refer to
Figure 16-7 (2-Frequency Directional
Comparison), Figure 16-8 (3-Frequency
Directional Comparison), and Figure 16-9 (2-
Frequency Directional Comparison).
3.8.9 EM Output Board
There are six relays on the board; six jumpers
(JU1 thru JU6) determine the function of the
relays. The choice of functions are:
• Guard
• Trip 1
• Trip 2
• Off
There are six additional jumpers which provide
“NO” or “NC” contacts for the alarm relays as
follows:
• K1 (JU7)
• K2 (JU8)
• K3 (JU9)
• K4 (JU10)
• K5 (JU11)
• K6 (JU12)
3.8.10 Voice Adapter PC Board
Operator controls consist of five jumpers, as
follows:
JU1 Receiver Squelch (IN or OUT)
When the jumper is “IN”, voice
keying squelches the receive audio
signal.
JU2/JU3 Compandor (IN or OUT)
When the jumpers are “IN”, the audio
is compandored; when the jumpers
are“OUT”, the audio is not compan-
dored. For best performance, we
recommend the “IN” position.
JU4 Signaling (TC or TCF)
When the jumper is set for “TC”, and
the handset (TJ1) is plugged into the
handset jack, the alarm cutoff from
the handset jack will cause the relay
to operate. When the jumper is set for
“TCF”, the presence of a signaling
tone will operate the relay.
JU5 Alarm Contacts (NO or NC)
When the jumper is set in the “NO”
position, and the relay is de-
energized, the alarm contacts will be
“OPEN”. When the jumper is in
the“NC” position, and the relay is de-
energized, the alarm contacts will be
“CLOSED”.
