This auxiliary output can be an alarm or event. Events may be turned ON or OFF in the
HOLD mode. EV1 will only appear when AUX1 = EV, under the SPCLFUNC menu, and
when the external event output board is connected.
Range: OFF or ON
Default: OFF
This auxiliary output can be an alarm or event. Events may be changed ON or OFF in
the HOLD mode. EV2 will only appear when AUX2 = EV, under the SPCLFUNC menu,
and when the external event output board is connected, or when TYP = "T" or "P" and
an external event board is connected.
Range: OFF or ON
Default: OFF
These auxiliary outputs are events. Events may be turned ON or OFF in the HOLD
mode. EV3 through EV8 only appear when the 8 event output, external board is
connected.
Range: OFF or ON
Default: OFF
EI monitors the status of the external event input. OPEN will be displayed if the external
event input is open, or will display CLOSE if terminals 22 and 24 are tied together. This
is a switch input, not voltage or current.
Range: OPEN or CLOSE
Default: OPEN if nothing is connected to the input.
ER1 is considered a fatal error; your system will shut down. When the Series 922 shuts
down, all outputs will be turned off, and the program will stop running. When an error
occurs, ER1 00XX will alternately flash with the SYSTEM parameter. To clear an error,
ENTER the SYSTEM mode, and scroll to the ER1 parameter. Press ENTER. This
clears the error unless it is a re-occuring error and has not been resolved. Some ER1
errors are self clearing.
Range: 0 - 18
ER2 is considered nonfatal. If you are in the RUN mode, your program will continue
running unless it is a program error. ER2 00XX appears, and flashes alternately along
with the parameter that you are on. To clear an ER2, return to the ER2 parameter
under the SYSTEM mode. Press ENTER. If the error persists, refer to the Error Code
list at the end of the manual to clear.
Range: 0 - 40
Alarms 1 and 2 are considered nonfatal. If you are in the RUN mode, your program will
continue to run. ALMX XX appears and flashes alternately with the parameter you are
presently on. ENTER the CLR ALARM parameter to clear a latching alarm. A non-
latching alarm clears itself once it falls within the alarm limits.
Range: 1 High, 1 Low, 2 High, 2 Low
From any RETURN, you can go back to SYSTEM prompt.
