TABLE 2-4. TRIGGER PORT PIN ASSIGNMENTS
CONNECTOR PIN SIGNAL NAME FUNCTION
TRIGGER PORT
(connector A1J3)
1 LOGIC GND Return for EXT TRIGGER and REMOTE ON-OFF signals.
2 REMOTE ON-OFF Logic 0 or short-circuit referenced to logic GND (pin 1) sets
the output OFF (output disabled). Logic 1 (TTL or 5V-
CMOS) or open sets the output to ON (output enabled).
This logic can be reversed (see 3.3.2.1 for details.).
When using digital control this pin can also be a) disabled
to allow OUTP ON and OUTP OFF to control the output or
b) configured to put the unit in standby (see PAR. B.15).
Logic 0 or short circuit for at least 100
µ
sec disables the
output and puts the unit in standby, however Logic 1 (TTL
or 5V CMOS level) does NOT enable the output. A remote
OUTP ON command must be used to enable the output.
Response to this signal is relatively slow (200mS max).
3 NOT USED
4 EXT. TRIGGER INPUT Logic 0 for at least 100
µ
sec or short-circuit referenced to
logic GND (pin 1) causes a trigger event. Logic 1 (TTL or
5V CMOS level) rearms the trigger feature. Response time
is 500
µ
sec max.
TABLE 2-5. EXTERNAL PROTECTION CONNECTOR INPUT/OUTPUT PIN ASSIGNMENTS
CONNECTOR PIN SIGNAL NAME FUNCTION
EXT. PROTECT PORT
(connector A2A5J7)
1 SD_EXT_K
Cathode of LED optocoupler (through a 510 ohm resistor) which is
used for external isolated shutdown. Anode of LED is connected to
(A2A5J7) pin 2. A positive voltage (3.5 to 15V) at pin 2 (referenced to
pin 1) shuts down the unit. This signal shuts down unit functionality.
The unit remains powered, but no output is available and the front
panel POWER/FAULTLIMIT LED will turn red. Response is relatively
fast (100
µ
S max.). To resume normal operation it is necessary to
cycle power off, then on.
2 SD_EXT_A
Anode of LED optocoupler which is used for external isolated shut-
down. (See pin 1 above.)
3 PG_EXT_C
Collector of optocoupler-transistor which is used for external isolated
“power OK” flag. Transistor emitter is connected to (A2A5J7) pin 4.
When unit is operating normally, transistor is saturated. Current
through transistor should not exceed 5mA and supply voltage should
not exceed 15V.
4 PG_EXT_E
Emitter of optocoupler-transistor which is used for external isolated
“power OK” flag. (See pin 3 above.)
5 EXT_C
Collector of optocoupler-transistor which is used for external isolated
“Output OFF” flag. Transistor emitter is connected to (A2A5J7) pin 6.
When output is OFF, transistor is saturated. Current through transis-
tor should not exceed 3mA and supply voltage should not exceed
15V. See NOTE below for alternate function.
6 EXT_E
Emitter of optocoupler-transistor which is used for external isolated
“output OFF” flag. (See pin 5 above.)
NOTE: Upon receipt of LIST:SET:TRIG command (PAR B.72), the Output Off flag (EXT_C/EXT_E) no longer represents output on/
off state. Instead, this signal can be used to trigger an external device. The transistor state (conducting or not conducting)
and the pulse width duration is controlled by the LIST:SET:TRIG command. Upon receipt of LIST:CLE command (PAR
B.49) the Output Off flag reverts to representing output on/off status as described above.
