LED indicators
The C232 has a total of 13 LED indicators for parallel display of binary signals. The
Address List in the Appendix gives information about the configuration options for all
LED indicators. The following table provides an overview.
LED indicator Description on
the label strip
as supplied
Configuration
H 1 ‘HEALTHY’ Not configurable. H 1 signals the operational readiness of the device
(supply voltage present).
H 17 ‘EDIT MODE’ Not configurable. H 17 signals the fact that the user is in the ‘EDIT
MODE’. In this mode, parameter values can be changed. (See the
section entitled ‘Display and Keypad’ in Chapter 6.)
H 2 ‘OUT OF SERVICE’ Permanently assigned to the function MAIN: Blocked/faulty.
H 3 ‘ALARM’ Permanently assigned to the function SFMON: Warning (LED).
H 4 ‘TRIP’ The factory-set configuration is shown in the Terminal Connection
Diagrams. These diagrams are found in the appendix to this manual or
in the Supporting Documents shipped with the device.
H 5 to H 12 ---- The user has the option of assigning functions to these LED indicators.
The arrangement of the LED indicators on the local control panel is illustrated in the
dimensional drawings of Chapter 4.
An operating mode can be defined for each LED indicator. Depending on the selected
operating mode, the output relay will operate in either energize-on-signal (ES) mode
(‘open-circuit principle’) or normally-energized (NE) mode (‘closed-circuit principle’) and
in either latching or non-latching mode. For LED indicators operating in latching mode,
the operating mode setting also determines when latching will be canceled.
