DC (mV) - - As if Process Variable is over-range
DC Linear: Ranges Selectable from Front Panel (with displayed codes):
(Changes may also be required to the CPU PCB link jumpers - see Subsection 2.5)
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.
A.2 DUAL SETPOINT SELECTION INPUT (OPTION)
Type: Voltage-free or TTL-compatible
Voltage-Free Operation: Connection to contacts of external switch
or relay; contacts open = Setpoint 1
selected (minimum contact resistance =
5000 Ω ), contacts closed = Setpoint 2
selected (maximum contact resistance =
50 Ω ).
TTL levels: To select Setpoint 1: –0.6V to 0.8V
To select Setpoint 2: 2.0V to 24V
