Table 35 AC8 - default settings for inputs and outputs

DEFAULT SETTINGS - DIGITAL INPUTS (FROM Table 15)

Feature	Default	Other Options
LABEL	DEVICE_1 - DEVICE_8	Any name (up to eight characters)
NORM OPEN/CLOSE	NO (Normally open)	NC (Normally closed)
ALARM/EVENT	AL (Alarmable)	EV (Event)
LATCHED	L (Latched) / Y (Yes)*	NL (Unlatched) / N (No)*
DELAY	00:01 (1 second)	Any time (in minutes and seconds) from 00:00 to 99:59

* NOTE: Different abbreviations are used to designate a digital input as Latched (L/Y) or Unlatched (NL/N) in Select Input/Set Inputs screens.

DEFAULT SETTINGS - ANALOG SENSOR INPUTS (FROM TABLE 17)

Feature	Default	Other Options
CONNECTED*	N (Not connected)*	Y (Connected)**
LABEL	SENSOR_1 - SENSOR_4	Any name (up to eight characters)
UNITS	DEG	Any units (up to three characters)
4 mA	+045.0	Can define up to two decimal places—e.g., -99.99
20 mA	+096.0	Can define up to two decimal places—e.g., +99.99
OFFSET	+000.0	Can define up to two decimal places—e.g., +00.00
ALARM/EVENT	AL (Alarmable)	EV (Event)
LATCHED	N (Unlatched)	Y (Latched)
LOW SETPT	+0050.0	Can define up to two decimal places—e.g., -999.99
HIGH SETPT	+0090.0	Can define up to two decimal places—e.g., +999.99
SENSOR DELAY	00:01 (1 second)	Any time (in minutes and seconds) from 00:00 to 99:59

* If a sensor is configured as N (Not connected), the display will show an empty reading (blank spaces). ** If a sensor is configured as Y (Connected) and is functioning properly, the display will show a reading.

If the connected sensor is not functioning properly, the display will show dashes (------) indicating a problem.
