AMETEK DLM Series - Manual (Page 46)

Advanced Operation DLM-E 3kW & 4kW Series Power Supplies
Section 4.2 Configuring for Remote Programming, Sensing, and Monitoring provides a
reference to the function and location of these controls, and procedures for making any required
changes.
4.2 Configuring for Remote Programming, Sensing,
and Monitoring
This section lists front panel switch, J11 connector, and rear panel DIP switch functions for the
DLM–E Series supplies. Subsequently, it provides a location diagram (Section 4.2.2), in addition
to procedures for resetting the jumpers and switches (Section 4.2.3), and for reconfiguring or
making connections to the J3 connector (Section 4.2.4).
You will find remote programming procedures and diagrams covered in more detail in
Section 4.3, remote sensing in Section 3.3, and remote monitoring of readback signals and
status indicators in Section 4.6.
4.2.1 Programming, Monitoring, and Control Functions
Front Panel REMOTE/LOCAL Switch
You can use the REMOTE/LOCAL Programming switch for remote programming. When set to
REMOTE programming, control of OUTPUT VOLTAGE, CURRENT LIMIT and OVP is passed
to external voltage or current sources which are connected to the J3 connector. Resetting the
switch to LOCAL position returns the supply to local (front panel) control. See Section 4.3 for
more information about using this switch.
External J3 Connector (see Figure 4–1)
The factory default configuration for the J3 connector is with no jumpers or other connections.
The external J3 connector provides user access to the following functions:
• Remote programming of output voltage or current limit, and for OVP
• Remote monitoring of the following readback signals and status indicators
Readback Signals Status Indicators
Voltage Monitor Overtemperature shutdown
Current Monitor OVP status
Remote/Local programming mode
Volt/Curr operating mode
•
Remote programming of the shutdown function using DC or TTL compatible signals
WARNING!
Use extreme caution when biasing the output relative to the chassis due to
potentially high voltage levels at the output and J3 terminals.
