Alarm code display, Alarm classification | Honeywell DCP552 Mark II

Chapter 10. TROUBLESHOOTING

■Alarm code display

The DCP552 is designed to alternate display of the following alarm codes and normal display items in one-second intervals on display panel 1 when input failures or instrument system failures are detected.

In cases of multiple alarm codes, display of the codes is alternated with normal display items, starting in order from the alarm code with the smallest number.

■Alarm classification

	PV range alarm group		: AL01 to AL04
	Measuring instrument alarm group		: AL90 to AL99, and battery voltage drop
			(In case of battery voltage drop, BAT LED
			of the console is flickered.)

Alarm	Alarm name	Contents		Countermeasure
code
AL01	PV1 overrange	PV1 is more than 110%FS.		Check PV1.

AL02	PV1 underrange	PV1 is less than –10%FS.

AL03	PV2 overrange	PV2 is more than 110%FS.		Check PV2

AL04	PV2 underrange	PV2 is less than –10%FS.

AL90	Board configuration failure	Incorrect board configuration		Request the repair.

AL92	Adjustment value is abnormal.Analog input/output			Request the repair.
		adjustment data were broken.

AL93	Setup data is abnormal. Setup data were broken.			Check the setup data, and reset
				the data.

AL94	Variable parameter is abnormal. Variable parameter were			Check the variable parameter,
		broken.		and reset the data.

AL95	PID parameter is abnormal.	PID parameter were broken.		Check the PID parameter,
	(Fixed command control data is abnormal.)			and reset the data.

AL96	Program data is abnormal. Program data were broken.			Check the program data,
				and reset the data.

AL97	Event configuration data	Event configuration data		Check the event configuration data,
	is abnormal.	were broken.		and reset the data.

AL99	PROM is abnormal.	System program were corrupted.		Request the repair.

*1: When AL90 is generated, the alarm code stays on and continued operation is disabled.

*2: Data checks performed by AL93 and AL97 may fail to detect corrupted data. When this happens, the alarm can be turned off by entering normal data.
