4.1 Display of status, alarm and fault signals

Categories of signals	The signals (messages) to be available for thyristor power con-
and possibilities of	verters series DCS 500B / DCF 500B or DCP 500 are subdivided
display	into five
	categories:
		General messages
		Starting errors
	F	Fault signals
	A	Alarm signals
	[112 . .]	Status signals through parameters

A seven segment display on the control board SDCS-CON-x of the thyristor power converters series DCS 500B / DCF 500B or

DCP 500 is used to show general messages, starting errors, fault and alarm signals. The signals (messages) are displayed as codes. If the codes consist of several parts, the characters/individual digits will be indicated for 0.7 sec one after the other, e.g.:

0.7s

F 14 = Speed measurement fault

In addition to this the DCS 500B DCF 500B or DCP 500 combined with the LCD of the control panel CDP 31x will be able to show the fault and alarm signals as well as the status signals (selected by signal numbers [112 . .]) as clear text.

Note: The languages to be available for display as text depend on the type of Control Panel and the Software version

( ⇒ Chapter „Handling of Control Panel CDP 31x“).

For subsequent evaluation via binary outputs or serial interfaces the 16 bit informations FAULT WORD1 [11101], FAULT WORD2 [11102] and FAULT WORD3 [11103] as well as ALARM WORD1 [11104], ALARM WORD2 [11105] and ALARM WORD3 [11106] contain several fault and alarm signals as a binary code.

Each fault and alarm signal is coded as an individual error code to the LATEST FAULT [11106] and LATEST ALARM [11107].
