To Replace the Power-Line Fuse
52 E3632A Service Guide
To Replace the Power-Line Fuse
The power- line fuse is located within the power supply's
fuse- holder assembly on the rear panel (refer to the E3632A
User’s Guide). For 100 Vac or 115 Vac operation, you must
use a 4 AT slow- blow fuse (Agilent part number 2110- 0996).
For 230 Vac operation, you must use a 2.5 AT slow- blow
fuse (Agilent part number 2110- 0999).
To Disconnect the Output Using an External Relay
When the output of the E3632A is turned off, it is
implemented by setting the output to 0 V and 0.02 A. This
gives a zero output voltage without actually disconnecting
the output. To disconnect the output, an external relay must
be connected between the output and the load. A TTL signal
of either low true or high true is provided to control an
external relay. This signal can only be controlled with the
remote command OUTPut:RELay {OFF|ON}. The TTL
output is available on the RS- 232 connector pin 1 and pin 9.
When the OUTPut:RELay state is ON, the TTL output of
pin 1 is high (4.5 V) and pin 9 is low (0.5 V). The levels are
reversed when the OUTPut:RELay state is OFF.
NOTE
• TTL output of pin 1 or pin 9 of the RS-232 connector is available only
after installing two jumpers inside the power supply. See below for
more information.
• Do not use the RS-232 interface if you have configured the power
supply to output relay control signals. Internal components on the
RS-232 circuitry may be damaged.
