900CE
Remote Operation Interface
The Remote Operation Interface is an isolated input based on the RS-232
communication standard, and allows communication between the DC
Converter and the 900CE Remote Operation System (ROS). The purpose
of this interface is to provide status information and DC output
measurements from the 900CE to the ROS and to accept commands from
the ROS. For more information on the Remote Operation Interface, please
refer to the 900 Remote Operation System Manual and CAN Interface
document.
900CE Remote Operation System (ROS)
The 900CE Remote Operation System (ROS) is a personal computer-
based system for controlling the 900CE. The system consists of the
computer itself and any peripherals, and the 900CE Remote Operation
System application.
This software provides a graphical user interface for controlling and
monitoring the operation of the 900CE, a command language interpreter
that allows for simple implementation of complex test programs and
communication with the system.
HV Interlock (Front Panel)
Each channel of the 900CE has a High Voltage Interlock Switch (HVIS) for
added protection (Figure 2.6). The HVIS can put one channel of the 900CE
into Standby Mode without affecting the other channel.
Pin 1 (+V) is a system supplied +5 isolated voltage source that is to be
connected to Pin 2 (+sense). The Pin 3 (-sense) has to be connected to
the Pin 4 (the GND signal), which is the ground of the (+V) isolated supply.
A break in either one of these links will put that channel into Standby Mode
(open the output contactor and isolate the output of the 900CE from the
load). (See appendix V for proper wiring.)
NOTE: If this feature is not used, it is necessary to have mating
