and perform the check again. If the function continues to fail, contact
the factory for assistance.
3.4 REMOTE ANALOG CONTROL CONNECTOR (J1)
The Analog Control connector (J1) of the Remote Analog Interface on the
rear panel allows the unit to be configured for different operating
configurations: front panel and remote current programming, front panel and
remote voltage programming, output current and voltage monitoring, output
enable/disable, etc. Refer to Figure 3-12 for the connector pin-out diagram.
The setup and operating requirements of each configuration are provided in
Sections 3.5 through 3.8.3.
CAUTION!
In the standard, Remote Non-Isolated Analog Interface, the
programming/control circuits (signal returns through J1-6 and J1-24) are
electrically connected to the output power negative terminal of the supply (not
isolated). Proper connection of signal returns must be made with respect to
external programming/control equipment to ensure that ground/return loops are
not formed where output load current might flow through the external
connections to the J1 circuits (J1-6 and J1-24), possibly causing internal
damage to the power supply. Refer to Table 3
–5.

The option, Remote Isolated Analog Interface control, uses the same Analog
Control connector (J1) as the standard interface. However, this option fully
isolates the remote control signals and allows control of units not connected
to a common ground. Control signal returns are isolated from output power
negative terminal, which protects against potential damage from systems with
high energy electrical potentials or large ground loop currents.
Note:
Some standard, Non-Isolated Analog Interface programming signals
are not available with this option; see Table 3 –5 for details.
CAUTION!
The Remote Isolated Analog Interface option is not intended to allow
operation of the power supply at excessive voltages. Operation of Isolated
Analog Interface signals should be at SELV safety voltage conditions to
chassis ground. Refer to Section 1.2.2 for maximum terminal voltages.
