Changing the Position of a Switch
Whenever you change the position of a DIP switch, follow this procedure:
1. Remove power from the Series 922. Turn the front panel screw 90° counter-
clockwise.
2. Grip the front panel bezel and pull it straight out from the control case. The
control chassis will come out of the case as you pull the bezel.
3. Set the DIP switch to the position you want.
4. Return the control chassis to the case. Be sure you have it oriented
correctly. It will not fit in upside down, but check just the same. Press firmly,
but gently, to seat the chassis.

Switches
DIP Switch #1 determines a warm or cold start. A "warm" start will save all
programmed information in the 922's memory backup. A "cold" start is a "clean"
startup condition; all user-programmed information is deleted. Your Series 922
leaves the factory programmed for a warm start. DIP Switch #2 selects whether
all SPCLFUNC parameters will be displayed or not. DIP Switch #3 determines
whether the decimal point will be displayed in tenths of units for 0-5V or 4-20mA
input and DIP Switch #4 is for 0-5VDC/0-20mA input or 1-5VDC/4-20mA input
selection. DIP Switch #5 is not used, and DIP Switch #6 is a factory test/cali-
brate switch.

WARNING:
Doing a cold start
will cause all SETUP
parameters and files
to be lost. DO NOT
put DIP switch #1 in
the ON position
unless all user-
programmed
information is to be
cleared.
SPCLFUNC parame-
ters define the
personality of your
Series 922. Such as
input type, units of
measure, range,
calibration offset,
output action, alarm
type, and lock out.
