#2 mA Mid Value – This field displays the expected midpoint analog input
•
value in a three point calibration provided by the user during calibration.
#3 mA Max Value – This field displays the expected maximum analog input
•
value provided by the user during calibration.
#1 Raw Min Value – This field displays the measured minimum value read
•
from the device.
#2 Raw Mid Value – This field displays the measured midpoint value read
•
from the device.
#3 Raw Max Value – This field displays the measured maximum value read
•
from the device.
Status – This field displays one of the following:
•
Live – Current output is being driven by the selected measurement ID.
Hold – Current output is being driven based on the Hold Value (EU).
Low Alarm – The current output value is below the Min Current value.
High Alarm – The current output value is above the Max Current value.
Fault Low Alarm – The current output is below the value defined by the
Namur standard.
Fault High Alarm – The current output is above the value defined by the
Namur standard.
Current outputs can be calibrated using two or three points. The calibration process
for the current outputs should be completed by selecting Calibration from the
Functions menu or by clicking the fourth icon button, the wrench. Selecting either of
these options will guide the user through the calibration process step-by-step. For
further information, see Calibration.
There are two relay outputs on the system that allow the user to provide additional
process information from the detector to the outside world. The function of a relay
output is to provide alarm signal and/or totalizer pulses to an external system for
monitoring or processing purposes.
To access the information on the Digital Input tabs using only the remote transmitter
keypad, see
