6.2.3 Remote Enable/Standby
Using the SIM-BNC Interlock connector located
on the back panel of the amplifier, you can re
-
motely Enable the amplifier and/or place the unit in
Standby mode. See
Figure 6.12.
Remote Enable/Standby
Purpose:
Use a switch or optocoupler to remotely
disable the amplifier and place it in Standby mode.
Also, return the amplifier from Standby mode to
the Run condition.
Method:
Short PIN 4 of amplifier to Digital Ground
(PIN 17) using a dry contact switch or optocoupler.
In multi-amp applications, a switch can be used for
Parallel systems, but an optocoupler must be used
for Series systems. Multiple amplifiers (sharing the
same Sampled Common power connections) can
be simultaneously forced to Standby by daisy-
chaining Interlock (PIN 4) across amps.
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.
6.2.4 Remote Monitoring of Current
Using the SIM-BNC Interlock connector located on
the back panel of the amplifier, you can remotely
monitor both voltage and current output.
Use a male, 25-pin D-Sub connector and high-
quality wire to build the desired circuits.
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 6.13.
Signal Type:
DC
Level when Asserted:
2105: 5A/V; 2110/2120:
20A/V
Level when Deasserted:
0V
