2.6 COOLING
The power devices used within the power supply are maintained within their operating tempera-
ture range by means of internal heat sink assemblies and by two cooling fans. Periodic cleaning
of the power supply interior is recommended. Do not obstruct any vents on the unit. If the power
supply is located within a confined space, take care that the ambient temperature, which is the
temperature of the air immediately surrounding the power supply, does not rise above the speci-
fied limits (see Table 1-2).
2.7 SETTING UP THE UNIT
The following paragraphs describe the connections and initial BOP setup needed to operate in
the desired mode.
2.7.1 POWER-UP SETTINGS
The BOP uses three DIP switches (S1, S2, S3 shown in Figure 2-2 and explained in Table 2-2),
each with five segments to establish initial conditions upon power-up. These switches can be
configured for a) Reset Power-up or b) Normal Power-up.
Reset Power-up (PAR. 3.3.2.1) is used to change the load type (load type determines how the
unit responds to the output OFF command, see PAR. 3.3.6), logic of The Remote On/Off signal
at pin 2 of the Trigger port, and baud rate. Reset power-up also resets the limits to factory
defaults (see PAR. B.143). When using the unit on for the first time, refer to PAR. 3.3.2.1 to per-
form a Reset power-up.
Normal Power-up (PAR. 3.3.2.2) is used to establish the GPIB address, configure the unit as
either standalone or part of a multi-unit configuration, and establish how the unit is to be con-
trolled (analog or digital), select operating mode (voltage or current), and select how protection
limits are to be controlled.
Refer to PAR. 3.2 for a summary of factory default settings established by the power-up
switches. The Reset Power-up (PAR. 3.3.2.1) must be used to change the load type, baud rate
or reverse the logic of Remote On/Off logic at Trigger port pin 2. Otherwise refer to PAR. 3.3.2.2
to establish normal power-up settings.
