Strain Gauge: Depending on user setting lnPF can cause input to fail
high scale or low scale reading. Reading will fail on either, Sig+ or Sig-
loss, or incorrect excitation output <0.8mA and >50mA supply.
High alarms activate for sensor break. Linear 4 to 20mA, 2 to 10V and
1 to 5V DC: Low alarms activate for sensor break.
Note: Sensor break not detectable on 0 to 20mA, 2 to 10V
and 1 to 5V DC input types.
Isolated from all outputs.
Universal input must not be connected to operator accessible circuits
if single relay outputs are connected to a hazardous voltage source.
Supplementary insulation or input grounding would then be required.
If the Logic State setting in Config Mode = CLS, Reset or Tare occurs on
an Open to Closed transition, or high (3 to 5VDC) to low (<0.8VDC)
transition.
If Logic State setting in Config Mode = OPN, Reset or Tare occurs on a
Closed to Open transition, or low (<0.8VDC) to high (3 to 5VDC))
transition.
No isolation from inputs and other outputs.
