NOTE:
The rL and rH

to scale the display
for process inputs,
and/or will scale the
retransmit range for
process output. rL
and rH also limit the

depending on control configuration.
Entering the Setup Menu
The Setup Menu displays the parameters that configure the Series 942's features
to your application. Enter the Setup Menu by pressing the UP/DOWN keys simul-
taneously for 3 seconds. The Lower display shows the LOC parameter, and the
Upper display shows its current level. All keys are inactive until you release both
keys. You can reach the LOC parameter from anywhere except the Run menu.
While in the Setup menu, all outputs are OFF.
Use the MODE key to cycle through the menu, and the UP/DOWN keys to select
Setup data. You will not see all parameters in this menu, depending on the unit's
configuration, model number, and LOC parameter. After stepping through the
menu it returns to the control set point parameter under the Operation menu.
