When Interlock (PIN 4) is shorted to Digital Ground
(PIN 17), the amplifier is placed in Standby mode.
When switch is open, the amplifier is released to
the Run condition.
Signal Type:
DC
Level when Asserted:
0 to 8 V
Level when Deasserted:
10 to 15 V
IMPORTANT:
The amplifier must be configured for
Ready mode at startup (factory default) or the Run
button must be pressed at the amplifier front panel
at startup. The Remote Enable/Standby circuit will
not function if the Startup to Standby Latch has
been activated on the amplifier.
5.1.4 Remote Monitoring of Current
Using the SIM-BNC Interlock connector located on
the back panel of the amplifier, you can remotely
monitor current output.
Remote Monitoring of Current Output
Purpose:
Use a voltage meter to monitor output
current.
Method:
Connect a voltage meter to monitor
the output current being produced by the ampli
-
fier. Connect across PIN 6 (I MON+) and PIN 10
(Sampled Common). See
Figure 5.5.
Signal Type:
DC
Level when Asserted:
20A/V
Level when Deasserted:
0V
Purpose:
Use a voltage meter to monitor output
current when output is not balanced.
Method:
Connect a voltage meter to monitor
the output current being produced by the ampli
-
fier. Connect across PIN 6 (IMON+) and PIN 19
(IMON-). See
Figure 5.6.
Signal Type:
AC
Level when Asserted:
10A/V
Level when Deasserted:
0V
CAUTION:
To avoid ground loops, isolation from
ground must be provided. Use of a differential
probe is recommended.
