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

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 MODE keys to reach the
ER1
or
ER2
parameter and press ENTER.
Press
ENTER or transmit a 0.
If the code returns, or if
the 920 replies to a data communicated
“?
ER1
”
or
“?
ER2”
query with the same code, the problem still
exists. Refer to the Series 920 manual or the
Series 920 Data Communications Manual.
ER1,
ER2, and ALM can only be cleared
when in the SYSTEM menu.
How to Clear an Alarm Code
An alarm code will alternately flash with the pa-
rameter 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.
First correct the alarm condition and return to the
SYSTEM menu
.
Press the MODE key until you
see the CLR ALARM parameter. Press ENTER to
clear latching
alarms
that are no longer in an alarm
I
condition.
RUN
Menu
One of the three step types will be displayed
depending on the type of step
PROGRAMmed.

~
be visible.
