In the SETUP menu of the Series 920, an ACCESS number (0,
1, 3,5) must be selected to
enter the personality of your Series
920 into the CALIB, PID, MANUAL, and SPCLFUNC parame-
ters.
Displayed information which gives the operator/programmer
real or "actual” data, i.e., actual process temperature. See
“Programmed display data.”
A condition generated by the Series 920, indicating that the
process has exceeded or fallen below the limit point.
Present only when AUX1 = AL and DIP switch #7 is ON.
Determines whether the alarm type for Auxiliary Output 1 will
be a process alarm or a deviation alarm.
Present only when AUX2 = AL and DIP switch #7 is ON.
Determines whether the alarm type for Auxiliary Output 2 will
be a Process alarm or deviation alarm.
Control feature that inhibits automatic reset action outside of
the proportional band.
Data entry points where a microprocessor-based control
“prompts” or asks the operator/programmer for information
input.
One of six step types under the PROGRAM menu of the Series
920 that can be programmed to automatically start at a certain
time, depending on the DAY, HOUR, and MIN parameter
settings.
This parameter detemines whether Auxiliary Output 1 will be
an alarm or event output for the Series 920. Not displayed if
DIP switch #7 is ON.
This parameter detemines whether Auxiliary Output 2 will be
an alarm or event output for the Series 920. Not displayed if
DIP switch #7 is ON.
When AUX1 = AL, the Series 920 will display this parameter
representing the high process alarm or high deviation alarm for
Alarm 1.
This parameter represents the low process alarm or low
deviation alarm for Alarm 1 of the Series 920. Displayed only
when AUX1 = AL.
Represents the high process alarm or high deviation alarm for
Alarm 2 of the Series 920. Displayed only when AUX2 = AL.
The low process alarm or low deviation alarm for Alarm 2 of the
Series 920. Displayed only when AUX2 AL.
An offset of the process variable. This number is added to the
value that the system derives. The final result is used for the
set point as well as a front panel indication.
