Codes
ER1 Codes Shut Down Outputs
The Series 922 will shut down its outputs
whenever an ER1 code occurs. An ER1 code
usually represents a Series 922 malfunction.
Check These Items First
Anytime you see an ER1 error code, check for
these four items first, then follow the
recommended action listed by the code:
a) Low line voltage
b) Noisy environment, noise event
c)
Vibration
d) Temperature or moisture over
specification
ER2 Codes Do Not Shut Down Outputs
ER2 error codes are data communication
system related or file programming related.
Clearing an Error Code
To clear an Error Code from the
alphanumeric display, first correct the
problem, then return to the SYSTEM menu.
Use the UP/DOWN keys to reach the ER1 or
ER2 parameter and press ENTER. Press
ENTER or transmit a 0. If the code returns,
or if the 922 replies to a data communicated
"? ER1" or "? ER2" query with the same
code, the problem still exists. Refer to the
Series 922 manual.
ER1 error codes can only be cleared when in
the SYSTEM prompt and ER1 XX is
flashing.
ER2 error codes can be cleared by returning
to the SYSTEM menu, or by pressing the
ENTER key while in the RUN mode.

How to Clear an Alarm Code
An alarm code will alternately flash with the
parameter that you are presently on. If the
LAT alarm value is NLAT, your alarms are
non-latching and will clear automatically
when the ACTUAL display value returns to
within the normal operating band. If LAT =
LAT, the alarms are latching, and must be
cleared. Alarm conditions can be cleared, by
pressing the ENTER key, while in the RUN
mode, or in the CLR ALARM parameter
