DC Linear: Ranges Selectable from Front Panel:

(Changes may also be required to the CPU PCB link jumpers - see Volume I Subsection 2.5.1.)

Scale Range Maximum:	–1999 to 9999.	Decimal point as required.
Scale Range Minimum:	–1999 to 9999.	Decimal point as for Scale
	Range Maximum.
Minimum Span:	1 display LSD.
Sensor Break Protection:	Applicable to 4 - 20mA, 1 - 5V and 2 - 10V
	ranges only. Break detected within two

seconds. Control outputs set to OFF (0% power); Alarms operate as if the process variable has gone under-range.

REMOTE RUN/HOLD INPUT (OPTION)

Type:	Voltage-free or TTL-compatible;
	edge-sensitive.
	OFF-ON transition - currently-selected
	program will run or (if currently held)
	resume running.
	ON-OFF transition - currently-running
	program will be held.
Voltage-Free Operation:	Connection to contacts of external switch
	or relay; contacts open = OFF (minimum
	contact resistance = 5000￿), contacts
	closed = ON (maximum contact resistance
	= 50￿).
TTL levels:	OFF: –0.6V to 0.8V
	ON: 2.0V to 24V
